Samsung TV Makes Clicking Sound and Won't Turn On

I like fixing things myself whenever possible. Fixing my Samsung TV was intimidating at first, but it was actually fairly easy.


How to Fix a Samsung TV That Won't Turn on or Clicks

LCD TVs have a known problem with capacitors going bad. If your Samsung LCD TV won't turn on or makes repeated clicking sounds, there is a very good chance that you can save hundreds of dollars doing this simple repair yourself.

I know, I know. You're thinking, "Tinker inside my LCD HDTV. Are you crazy?" No, I'm not crazy. This is a repair almost anyone can do.

Don't have a Samsung? Read anyway, this guide will help you with any brand of LCD—bad capacitors are very prevalent in modern electronics.

Tools Required

You will need the five items below for this repair:

  1. Soldering Iron & solder
  2. Phillips Screwdriver
  3. Pliers
  4. Wire Cutters
  5. Samsung Repair Kit

Note: You will identify which capacitors you need in step five.

Need a soldering iron? No problem. They are cheap and easy to use. I highly recommend the J&L 60 Watts Soldering Iron. It's about 20 bucks. If you're looking for the lowest price possible, this 60W soldering iron with stand is about $8 (shipped prime) and will work.

Got everything you need? Time to dig in!

Optional tools.

Optional tools.

These tools aren't required, but they can make the process easier.

  1. Magnetic, ratcheting, flexible screwdriver (to help remove all the casing screws)
  2. Electric Screwdriver (to help remove all the casing screws)
  3. Desoldering wick (absorbs melted solder)
  4. Solder sucker (remove melted solder)
  5. Flux Pen (flux on solder makes it flow and less "sticky")
  6. Multi-Meter (test for bad Caps, helpful if there are no visual clues)

Step One: Remove Stand

After unplugging everything on the TV, you will need to remove the stand. If your TV was wall mounted you will need to remove the TV from the wall, and remove the mounting bracket from the back of the TV.

Red arrows: Remove these four screws to remove stand from TV.

Blue arrows: Remove these four screws to remove a wall mount (not shown) from your TV.

The TV sits on top and inside the stand, so it wont just flop over when you remove the stand screws, but it's always safer to have a friend hold the TV upright as you remove the screws from the stand. Then each of you grab a side and carefully lay it flat on a carpeted surface.

Step 1: Remove Stand.

Step 1: Remove Stand.

Step Two: Remove All Screws That Attach the Back Casing of the TV

The below images document where to find these screws on the TV so that you don't miss any!

Step Three: Remove Wiring Harnesses From Circuit Board

Remove the seven different wiring harness located on the circuit board. A simple tug on the connector clip (not the wiring) should be sufficient to remove them.

Step Three: Remove wiring harnesses from the circuit board.

Step Three: Remove wiring harnesses from the circuit board.

Step Four: Remove Screws Holding Down Circuit Board

Remove the six screws shown on the picture above and remove the circuit board from the TV chassis. This board is a power supply board and not particularly sensitive, but it is always a good habit to handle these boards carefully and by the edges.

Step 4: Remove screws that hold down the circuit board.

Identifying Bad Capacitors

Usually, but not always, capacitors will show visible signs of failure. There are two main types of visible failure.

Bulging Vents

When it fails, the chemical reaction inside the capacitor can produce hydrogen gas, so capacitors have vents cut into the tops of their aluminum cans. These are intended to break and release the gas that has built up inside the capacitor. So, a capacitor which has failed can show bulging at the top. Below is an example.



Another sign of a failed capacitor is leaking fluid (electrolyte). This can be an orange or brownish discharge from either the top or bottom of the capacitor. Usually, with leaking the capacitor will also be bulging. But a capacitor can bulge but not leak.


Again, we want to emphasize that capacitors do not always show visible signs of failure. But, if you see signs of this on your board, you can be confident that you're close to fixing your TV. If you don't see these signs of failure, but your TV had the tell-tail clicking sound, you still can be fairly certain the steps below will fix your TV.

Step Five: Identifying the Problem Capacitors

If you have a Samsung 550 Series LCD (and perhaps other models), and you came to this site because your TV won't start, and it makes a clicking sound, then the picture above shows the capacitors that should be replaced in the red box. If you have a different make or model you will need to visually inspect and replace any damaged capacitors.

Below are actual closeups of my TV's board. Notice how the blue capacitors in the foreground are bulging. These are the capacitors I will replace. All other capacitors look OK. If you can find replacements for all 4 of these capacitors, and any others that show visual signs of going bad, I recommend replacing them all while you're in here.

I couldn't find the specific replacements for the "black" capacitors (820 uf 25V) at my local electronic store, and since they looked OK, I just replaced the the bulging ones. But again, if you can find replacements, and since the capacitors are cheap, replace all 4 of these if possible (and any other ones showing signs of damage) while your working in here.

** Watch ** Removing and Replacing Capacitors

Step Six: Remove Capacitors

Capacitors have polarity. What this means is, like a battery, they have a positive (+) and a negative (-) side. Before removing any capacitor, note which side the white stripe of the capacitor is facing. You will need to put in the new capacitor in the same direction. You probably noted on my pictures that I actually made a note on the aluminum heat sink with a pen.

Now that you've identified the capacitors that look bad, turn the board over and carefully identify exactly which points on the board the wire leads from the these capacitors. Circle them with a "sharpie" type pen to keep track.

Grab your friend and have them help you on this next step. Balancing the circuit board on its side while using a hot soldering iron and pliers can be a bit tricky.

Plug in the soldering iron and give it 10 minutes to get hot.

With the circuit board on its edge, have your friend grab one of the capacitors with the pliers and apply a very gentle pulling pressure. Apply the tip of the soldering iron to one lead on the back side of the board and hold it there until you see the solder melt. Now switch to the other lead until it melts. Keep going back and forth on the leads. Each time the solder will melt faster. After going back and forth a couple times the capacitor will easily come out.

Repeat for each capacitor that you are replacing.


Let the iron do the work. If the capacitor does not easily pull out, do not force it.

Using Solder Wick


Step Seven: Get the Appropriate Repair Kit

Now that you've identified the bad capacitors, you need to go out and find replacements. The simplest way is to get a repair kit from Amazon.

If you want to trek out on your own, keep the information below handy when choosing replacement capacitors.

Capacitors are rated for their application and you must replace like for like. There are three ratings to identify:

  1. uF (Micro Farads)
  2. Temperature
  3. Voltage

uF (Micro Farads)

Ideally you should match the uF and the temperature rating exactly. But it is acceptable to use a capacitor rated higher uF if it is within 20% of the original.


Try to match the temperature rating, you can go higher, but not lower.


There is a bit of wiggle room on the voltage, but only if you're increasing it. Do not replace a capacitor with a lower voltage rating then the one removed.

Often, you can find replacement capacitors at your local electronic store. But it may be easier to buy replacements from Amazon.com.

For the Samsung LN46550A, you'll need:

  • 1000uf 10v Capacitor 105c High Temp, Radial Leads, or
  • 820uf 25v Capacitor 105c High Temp, Radial Leads.

For my repair I couldn't find a 1000 uF, 105 degrees and 10 Volts, so I replaced it with a capacitor that is 1000 uF, 105 degrees and 16 Volts. I've seen this repair successful with a capacitor up to 25 Volts, but I wouldn't go any higher than that.

Step Eight: Time to Install New Capacitors

Insert capacitor, making sure to place the negative side in the correct location. If there is hard solder in the hole, simply apply the soldering iron until solder melts and slip capacitor leads in.

Step 8: Install the new capacitors.

Step 8: Install the new capacitors.


Bend back the leads to hold the capacitor in place.


Carefully clip the leads so that only about 1/8" is protruding.


Place your soldering iron and solder on lead until the heat melts the solder. Once solder melts onto the lead, apply the iron on the lead and solder a few times to melt the solder cleanly on the lead. If you have solder flux, the solder will make a clean connection.


Capacitors installed. If there is any flux or solder residue, simply clean the area with a damp cloth.

Step 9: Reverse the Process

Put Your TV Back Together

  1. Attach the circuit board with the six screws.
  2. Reattach all seven wiring harnesses.
  3. Replace the back cover.
  4. Turn on TV and be happy that you save yourself a ton of money.

Did it work? Have any questions?

jordanjessica on September 02, 2020:

Incredible! Total cost of repair $5.97.

Drea on July 06, 2020:

Excellent video and yes it worked. Thank you!

Woman with a plan on July 03, 2020:

No capacitors look bad in anyway. Is there something else to do?

Happy Kiwi. on June 08, 2020:

Excellent and easy to follow tutorial.

I replaced 2x 25Volt 1000uF capacitors on my 46inch tv (LA46A650A1M)

I already have necessary tools for this repair. Total repair cost is NZD$3 only.

Repair was successful and brought back a 12yo TV back to life again.

Guy With A Working TV on September 18, 2019:

Followed you guide and I have a working TV again!

Terry on September 17, 2019:

The repair worked great-Got the kit from amazon- find the capacitor that was bubbled up changed it .Clicking has stopped and now comes back on like it was new.Thanks

Discoverinfo (author) on February 09, 2019:

Fantastic to hear about your success Amy!

Dino and Vicky on January 11, 2019:

Yayyyyyy! A HUGE success! I researched the symptoms and found your blog, and Dino did the work. $5.93 for four capacitors.

Thank you so much!

Discoverinfo (author) on January 09, 2019:

If Capacitors look good, just replace them. The hard work is getting to them, with the casing all removed I would replace them all since they are inexpensive.

Chris on December 24, 2018:

Hi i just recently got a samsund Tv model UN55D6900WF and its making a clicking noise along with the power light flashing red. Ive looked at the power board but i dont see any of the capcitors buldged or leaking at all

Mark on December 08, 2018:

excellent tutorial. I did this a few years back and it worked for roughly another 2 years.....happened again and I got a new tv. screw samsung.

Abinav on November 17, 2018:

Amazing stuff man, my Samsung LCD tv gave me the same problem and I tried fixing it using your steps and it worked. Thanks for your step by step guide. Fixed my tv in 20 bucks.

Edward on November 14, 2018:

My samsung tv screen doesnt come on however when i press the power on button on the controller, the tv makes the sound charm like its going to come on, is this a simple fix?

dannymac84 on November 13, 2018:

Just brought a 10 year old TV back to life, Thanx!

allygh21 on October 27, 2018:

OMG OMG it worked!! Thank you SO much. I'm a single mum and this happened to my Samsung and I was like, I DO NOT want to pay $2K for a new TV because I hardly watch it, it's just good to have for the kids and to watch the news. So I followed your instructions, so easy to understand. I used to help my dad around in the shed when I was little but I'm no electrician and this was really easy to do. Two of the capacitors were obviously bad (bulging), so I replaced those but it still didn't work, so I took out the remaining five capacitors (which looked ok) and replaced those too. I bought some solder just to make sure the connections were all good, and replaced them all in probably half an hour. Turned it on - works like new!! My kids and I were high fiving! And this TV is over 10 years old. Total cost was around $20 for the soldering gun, another $15 for the solder, screwdriver, pliers and wire snipper, (all from Bunnings) and around $7 for all 7 capacitors (Jaycar). Total: $42 which is way better than the hundreds it would have cost to have it fixed or a new one. Thank you, this is seriously good karma for you. x

Brian on October 21, 2018:

Thanks worked great. Easy to follow instructions.

Ed Colwell on October 11, 2018:

Thanks so much. It worked like a charm and was so satisfying. The only additional googling I had to do was to identify the positive side of the capacitor. you made my day.

yoda89 on October 10, 2018:

What if all the capasitors look fine? New, even?

Joe on October 07, 2018:

Mine keeps turning on and off by itself! 1st guy tried to tell me it was cable box so called next day told me truth its power source went bad gotta get a new power source

Jason on September 27, 2018:

Thank you! Worked like a charm.

Roger Smith on August 29, 2018:

Thanks so much for sharing, replaced 5 capacitors, took about an hour and saved mucho bucks! Capacitors cost $2 each. TV works great! Had the clicking issue and wouldn't come on, now works like new!

Elaine Major on August 26, 2018:

No it did not work, followed the steps exactly and we still have the clicking!

JOHN HUSINKA on August 08, 2018:

My system board appears to be different than the one displayed. I have a Samsung Model: PSPF520501A. Do you have the layout for this model to show where the replacement parts go?

Thank you!



Barnabas Nath on August 01, 2018:

My 55" Samsung TV Series 7 is having the same issue, the power board looks bit different, lot of capacitors and doesn't feel any damage, model# BN44-00428B, which set of capacitors you reckon need to be replaced?

Kevin Headla on July 28, 2018:

My 55 inch would not turn on it just clicks I took off back panel took off power board I found a loose connection soldierd it it works fine so check all connections

Patrick on July 14, 2018:

Thank you so much for the details instructions! I fixed my samsung TV like others here. Thanks again!

Jack on July 10, 2018:

Thank you SO MUCH for the knowledge and walk-through! I was able to fix my broken Samsung TV!!

SirSabin on April 23, 2018:

This fix worked, to my great surprise and delight. Thanks!

Jasonvillen on April 08, 2018:

Too many similar comments with similarily fall into similar pattern

BB on February 04, 2018:

Worked, thank you. :-)

Cat on February 01, 2018:

" have a samsung tv and it turns off by itself and keeps making the clicking noise.

I opened it up and don't see any capacitors that are burnt or bulged.

Wonder what could be the issue."

I have relatively the same issue as Jack, although not only does it shut itself off, sometimes it won't turn on and also changes the av settings on it's own at times.

jpa57 on December 12, 2017:

This literally saved me about $1,000. Thanks a gazillion.

AM on December 05, 2017:

Will this work if it's a plasma TV as well?

I have a 65" Samsung but I'm not sure if it's plasma or lcd (it's not with is right now so can't check it out). My husband believes it is a plasma.

Whenever we turn on the TV with the remote or locally, it clicks but nothing turns on.

JD on November 18, 2017:

It worked for me!


Kris on November 12, 2017:

Can a screen be replaced doing it yourself? It's a 55" Samsung maybe two years old

otherthings on November 11, 2017:

I just followed these steps and fixed my 9-year-old Samsung LNT4061FX. Before, it would sit there clicking for 3-5 minutes before starting up. Now, it starts right up the first time. Thanks for the detailed instructions, they were perfect!

Carl Peters on November 06, 2017:

i have 52 inch samsung lcd t.v model ln52a650a1f. no back lights but has sound no 24 volts has 5 volts backlight start up but no 24 volts i used a led tester and it showed the backlight on for just to seconds, the high voltage transformers show no signs of working

Dave on October 19, 2017:

Great post! Clear and saved me a lot of money. Got to love Google searches for repairs. Thank you so much for providing the information.

Jay on October 13, 2017:

Bought the $8 capacitor kit and used an ancient soldering gun I think was my fathers. Followed the instructions and with exception of my sloppy soldering job, everything went as described. And now my tv works. THANKS!!!!! Saved me at least $400.

Great article on September 26, 2017:

Was quoted $800 to fix spent $30 on a iron and 2 capacitors thanks so much worked a treat !

Excellent Article! on September 07, 2017:

I had no idea what I was doing but knew I didn't want to spend $400.

You're step-by-step fixed my TV.


Thank you

Normd on September 04, 2017:

Worked perfectly! Thanks!

jack on August 14, 2017:

i have a samsung tv and it turns off by itself and keeps making the clicking noise.

I opened it up and don't see any capacitors that are burnt or bulged.

Wonder what could be the issue.

Doug on July 26, 2017:

This worked for me for my Samsung LN40A750R1FXZA. Same two capacitors as well. No leaking, just had the tops popped up a bit. Thanks for the excellent instructions.

If you have read this and are apprehensive, I recommend to give it a try anyway. At worst, you can replace the power supply board with a used one online for less than $40, so what do you really have to loose?

Thanks again!


anonymous on July 01, 2017:

These instructions were awesome. I have never soldered and I did not own any of the required equipment. I was able to purchase the equipment and repair parts for less than $30. The instructions were very easy to follow and the best part is that my TV is working again.

Thanks for sharing this awesome solution!

kaileykailey on June 13, 2017:

i bought same capacitors and i replaced them but it still giving me same sound like tic tic after couple of seconds but not turning on. i checked all the connection and everything please help me out

Arch Parsons on June 11, 2017:

Great article. Actually, I'm pretty sure I read it before. It turned out that my power supply board did not have a single bulging or leaking capacitor. Using a hair dryer as a test I found that blowing on the main board caused the clicking to stop and the tv to start in just a few minutes whereas blowing on the power supply or elsewhere made no difference. They tell me I need the capacitor C-102 included in the available online main board repair kit which costs $20. Trouble is I already bought a new tv, a 55 inch that cost approximately 15% what I paid for the 50 inch Samsung back in 2008. I'm trying to ditch the old tv as is for a small amount of money, otherwise it's off to the recycle depot. I have to make an effort not to become a hoarder.

Jammerui on June 10, 2017:

You know when the instructions start out saying it's simple and just $3.98 ....you know it's not for you.

Rob LaCroce on June 05, 2017:

Your directions were on point. My TV is fixed. Thank you.

Arch Parsons on June 02, 2017:

I removed the back of my Samsung PN50A530S2FXZC but all the capacitors looked perfect. I just ordered a new Vizio TV from Amazon. I'm guessing a lot of people are disappointed by the many sites and youtube with articles like this. It seems bad capacitors in the psu is only one of a myriad of other possibilities that can cause this issue including the main board which is impossible to scrounge for my Samsung now that Plasma tv's are obsolete.

sunshinelise on May 24, 2017:

OMG....I just fixed my TV! Thank you so much. My husband wasn't too happy about me fixing it, because if it worked he couldn't get a new one. Lucky me it worked! Thank you for saving me soooo much money! :)

thomas thomson on May 15, 2017:

There is another clicking that comes from the speakers,you will spend more than 4 buck trying to find that one so let me explain ,the stand by light blinks four times,then a click from the speakers,it is the tcon board not the capacitors,

McGruff753 on April 24, 2017:

Had this issue crop up shortly after my warranty expired. Called Samsung and because of the internet buzz (and I think there was a class action lawsuit to boot), they fixed it for free. Fast forward several years and it happened again. Used your steps to refresh my memory from when I watched the repair guy do it the first time. Found 3 different capacitors bad, and not the same ones that were originally repaired. Went to my local Fry's and for $5.81, my TV works like it did the first day I bought it. Thanks for posting this very helpful guide. It DOES save you money.

Pia on April 04, 2017:

My TV makes the clicking sound and will continue forever without turning on WHEN ITS COLD. I noticed it would turn on OK in the summer but not once it got cooler. If I use my hairdryer to heat up the area behind the switch, it will turn on after about a minute...unless its really cold in the house then it takes a couple minutes. I don't think I could replace a capacitor but I sure know how to operate my hair dryer. If that quits the replacement cost won't break me.

Ultimate electronics newbie on April 01, 2017:

It worked for me! I bought a kit on Amazon, replaced only the pooped caps and bam! turns right on every time. THANKS

Tom-Tom on March 23, 2017:

I have Samsung UN40ES6500 FXZA circa 2012. I have carefully inspected and all the caps look fine. No leaking or bulging and solder joints look good. what should I do next. I have the blinking red light and no turn on problem. Thanks in advance. TT

Rosesami on March 11, 2017:

Step 8 First picture:

I have one of those things that look like staples burnt in my power supply board, what are they? how to replace them if possible and where to buy them?

I have already replaced four bad capacitors by following this post instructions, was very helpful, but unfortunately mu case sligtly differ as one of those "staple like" is burnt.

Paul on March 10, 2017:

I have a ns42p650a11 plasma tv that the red light flashes and you hear a clicking noise 3 times then the red light stays on solid. I inspected all the circuit boards and all capacitors look fine. Not swollen or leaking. I replaced the power board and still does the same thing.

Queenie on March 07, 2017:

Yep, a new generation, but the same TV. 2008 LN46A550 series. I read about the repair and the class action, contacted Samsung and was told that the "assistance" ended in 2011, I believe. And that they "were kind enough to" extend it for a few months after it ended. But No GO now. So I had the bf crack it open and there were the 2 ea. 470uF and 820uF capacitors all puffed up. He ran over to Radio Shack but they didn't have but one of the four I need. I am about to buy on Amazon and will definitely buy up on the voltage, currently 25V for all. The trick for me was to figure out how much higher but it seems best to get as close to the older ones but still rated higher. Here I go looking ..........

Charlie Zollinger on February 28, 2017:

Am I the only person that could not fix it? I had 2 bad caps, the black ones. Replaced them and nothing changed. It still clicks and wont turn on. Do I need to replace every cap on the board even though they look perfect? And is that class action lawsuit still active? Also will that repair if covered be VOID since i tampered with it? thanks in advance.

Angelica on February 20, 2017:

Thank you so much for this! I've never touched a soldering iron in my life nor removed the back of a television, but this worked wonderfully for me. Now we have a working 46 inch tele that we had originally found for free!

Aldo on February 07, 2017:

I'd never done electronics before and with this tutorial fixed my tv together with my teenager son, simply brilliant.

Brandon on February 01, 2017:

Worked great for me! We lived with the slow TV startup for over a year before I fixed it, wished I had done it sooner. There is a kit with an assortment of the capacitors you need and some solder on Amazon. Just search Samsung TV repair kit.

Roman on January 17, 2017:

Hi, everything is presented very clearly and I began to follow that guide because my Samsung had clicking noise as I try to turn it on, and it just clicks for 2-3 min until it eventually switches on. Anyway as I opened the TV, all the capacitors look okay, as the new ones I bought in advance. Should I replace them anyway? Do you have any advice?

RyanO on January 12, 2017:

Will this fix work on the HP-T5054X/XAA?

Rich on January 08, 2017:

What a clear precise explanation you provided. A total novice who never soldered before replaced 4 capacitors for $9. Had to use 1000uf vs. 820 but no problem there. Problem fixed and the TV works like new. Thank you SO MUCH!!

Julliana on January 03, 2017:

A massive thank you, the steps are explained perfectly, I can't believe I fixed a tv all by myself. And to think it only cost £1.44 amazing. Thank you thank you thank you

Carl07866 on December 26, 2016:

Have a Samsung LN32A45OC1DXZA that is a bit over 8 years old and thought this discussion might be helpful. The problem started a few days ago when I could not turn it on or get it to stay on for more than a few minutes. The picture quality is fine and have not noticed any other problems. I opened up the back and all the capacitors look fine, no bulging or leaking. I notice a comment about a black box and Melanee's comment about, but it appears like the original author has not commented in 2 years. Any thoughts? We have had 8 good years with this TV and would like to avoid buying a new one if possible.

Don on November 15, 2016:

1 samsung series 5 530 lcd tv as shown in first post

2x 470uf 25v visibly buldged

2x 820uf 25v visibly buldged

2x 1000uf 16v looks ok, but replacing anyway

I'll go a voltage range higher than these ratings.

Best part of this is....the kids actually showed an interest and found this thread on their own. The boys pulled the board for me, and I'll replace the cap's. I'll give the repaired board back to them to re-install.

This thread is absolutely priceless. Your helping a younger generation learn that this doesn't have to be a throw away society.

Melanee on October 26, 2016:

Well, it sounds like we have a new generation of Samsung LED TV's experiencing the same problem. But after reading the two most recent posts I don't know if the solution is the same. I also have no visible signs of failure with my capacitors. I have a 2011 Samsung 55" 3D LED HDTV Model# UN55D6900. At this point I really don't know what to do. Your TV power supply board looks a little different than mine, I'm not even sure what capacitors I should be replacing. I think I am going to go on ebay and look for a new or refurbished power supply board, I just hope after doing that it does not end up being a problem in the main board or something else. If you or anyone has any info on the new generation Samsung LED TV problem please post. I will try to post again if and when I find a solution to my $2800.00, 5 year old TV that keeps making a clicking sound and won't turn on.

Brittney Briggs on October 08, 2016:

Can't thank you again for such great instructions for this simple fix!

Roy Anon on August 02, 2016:

Same here, I pay USD 60 to samsung and they come and check the LED, saying that it must be the whole things dead, and asking me to buy the LED screen @ USD 1500, But I am sure that's the PSU problem, because by disconnecting everything, just the PSU with power cord, it still clicking. So, I say no to samsung. I try to check it up by myself, all cap looks good, and I replace them anyway, and it still clicking. Finding information from the web for a few weeks, still no solution at all, and what I can say is that, that little black box F3PA005V keep clicking. I wonder if that relay box is damaged or what, anyone have idea on it?

Rion on July 29, 2016:

I don't think one could ever stress enough at how fantastic it is to have people like yourself who help out the millions of us who just don't have the money to repair or replace all of today's disposable products. My sincere thanks.

Unfortunately my TV is slightly different and I am getting conflicting info on what the problem is. My capacitors look to be in perfect shape, not that that is an indicator of health. I used a stethascope with the membrane replaced with a steel probe and located the part where the clicking is coming from. A small black box located right beside the power cord. With a voltmeter I found that the power jumped from 5v to 0v and back in time with the clicking sound. This is where I get confused. First I read that this is better than having to replace the whole board but shortly after I read references to installing the new board? I can't say where I read this because I've been on the net for two weeks and hit a lot of sites and only the useful tidbits remain. I tried ordering this part from Samsung but they only sell the whole board to a tune of $300 & change. I might have already sent for it in frustration but there seems to be some confusion as to whether the clicking part is the problem or something else has gone wrong and the clicking part is only a side effect. Would you be able to help me figure this out? It is a Samsung 55" LED. Model Code: UN55C5000QFXZC, Version No: CN01, S/N: Z2EH3CCB100015N. The black box # is F&T; F3PA005V, 5V__DC, 5A250V~AC, 5A30VDC, 5/80A250V~AC/0860. I have clear detailed photos of everything if you have an email I can send it to. I wondered if the supplier of these parts from China could be found and bought through them? As well I thought there must be other products that this part is used in, if this part is the problem. It's sad to say that I have been saving up for this TV for a decade and finally bit the bullet and bought it for my family at Christmas. I felt very confident in the product believing that Samsung was the cream of the crop. By the second Christmas we were not able to all gather around the fireplace channel. It sits now gathering dust beside my first TV that is still going strong; a 21" 30 year old GE piece of crap. An infuriating reminder of what we have allowed these companies to do to us. I look forward to any help you can offer.

I cannot tell you how much fun I had soldering for the first time!! July 2016, no more class action suit -- so I was on my own with my 2008 Samsung. But now it works great. $46 for parts and soldering iron at Radio Shack -- coulda saved about half by ordering through Amazon but I wanted to watch the Olympic Trials NOW..... Thank you so, so much for this site!

Awesome! on June 12, 2016:

Followed your directions and it worked perfectly. I definitely owe you a beer.

Fantastic. I had two visibly blown capacitors but replaced all four as a matter of course. Thank you so much for such excellent pics and explanations.

TV is up and running. How good is that !!!!

Edmond on October 14, 2015:

Many thanks for the tips, very helpful indeed. It was good to fix my tv and save the many dollars I had been charged by repair firms.

KC on June 17, 2015:

WOW !!!

It really worked !!

My daughter found this site as an alternative to buying a new TV. I read through the instructions and figured it was worth the time and nominal cost to give it a try.

I've never even seen a soldering iron before today, much less used one (although I have used a glue gun and the principle is pretty much the same).

$16.00 for parts at Radio Shack including the iron, an hour of work, some serious mother/daughter bonding time, and - voila! - the TV is working.

Thanks for the excellent instructions and a fun afternoon.

Samsung 52" 550. Replaced 2 caps with 25v 1000µF 105C. worked perfectly the first time! no prior soldering or electronics experience - I looked up a few youtube videos to make sure I was doing it right. thanks for great info!

Mal on November 26, 2014:

Great guide. LN46A650A. Started making clicking sound. Replaced 4 caps with 35V 1000µF 105C caps. Worked perfectly. Thanks a lot

Stan on November 08, 2014:

Your instructions were perfect....Thank you for taking the time to do all of this. I bought the parts through work, and one of our tech's replaced the caps. You saved me a lot of time and money. Thank you again !!! Bill

It worked great, thanks for your efforts in getting the answers out there!!!!

@tuffybug: Yes sounds exactly like a capacitor problem. Good luck.

tuffybug on July 14, 2014:

i have a philips 40 inch tv with the clicking sound when i attempt to turn the set on after it had been on for quite a while. it will turn on after 30 minutes or so and has been doing this for about a year. do you think it's still a failed capacitor problem? it's not that easy for me to disassemble the set by myself. there are no young strong people here available to assist me with a repair. the set is too heavy for me to maneuver by myself, so i don't want to try if you don't think the capicitors are the problem

@aj5933: Unfortunately, I don't have any diagnosis tips for this. If it were me, I

would buy replacement capacitors and start swapping them out. It's really

quite easy and cheap and I really have nothing to lose. Good luck

aj5933 on January 18, 2014:

I have a Phillips model 40PFL7505D that is doing the exact same thing. The problem is that when look at the circuit board all the capacitors look great. Any suggestions? aj

@gac95222: Awesome to hear!

gac95222 on January 06, 2014:

Thank you! Already had a soldering iron, so I fixed my tv for $8! Great work!

I have a Samsung LN46A550P3FX similar to the one you are working on here. It follows the same behavior you have here, sort of... When I received it, the minute you plug in the power, you get an alternating 'click' or audio 'pop' from the left or right speaker about once a second. The tv can not be powered on. Naturally I thought this was probably a power board issue too, so I tried to swap in a different power supply, and that one didn't really work either. Same issue, just the alternating audio 'pop' from the speakers every second until power is removed. Is this the same issue, or is the 'click' you're talking about different? Hope you can help!

Wow what a great info and lens! Just awesome!

Just want to say thank you. My Samsung 550 52in TV is fixed thanks to this great blog.
