EDIT: 03/09/12 (09/03/12 for you silly ol 'murricans, teehee) So this is the first time I've checked up on the instructable in over a year, honestly you'd think it wouldn't take me this long to realise Gmail was filtering out the notification emails as spam.
Anyhow; At the time of writing here in the UK I was told that this was not covered under warranty and that I would have to pay £150 to have the board replaced. It seem in other countries samsung are somewhat more benevolent and that since the time of writing some sort of legal action has occurred regarding the subtle design flaws that have a tendency to show themselves just after your warranty expires. So should you be in some kind of mental debate over the options available to you DO NOT open up your TV first. Phone Samsung, see if your model is on this list, read up on the legal situation wherever you live.
It seems I was also borderline illiterate at the time of writing so at some point I will be re writing this in a comprehensible manner.

if your looking at this then you probably have a samsung tv thats broken. This instructable is for how to fix one of the most common faults in samsung LCD tvs. This applies to pretty wide range of models, but in short the ones with the piano black bezel are all affected (That is those with the problem are all fixable in this way). when you turn the tv on it should click once. this problem is that it clicks more than once. first twice, then 5 times then ten then 50 and so on, until eventually it takes about 10 minutes to turn on. Here is how you can fix that problem

I called Samsung. There is some settlement on some brands of Samsung LCD TV's sold before 2008. I spoke to a nice lady at 888-899-7602 who asked for my model number and serial number, then took my info to arrange for a local repairman to come by within 1-2 days to check the capacitor and replace the power components at no charge. SO glad I read this page and called Samsung before having it shipped off and spending a lot of money. Hopefully I will get extended life from this TV set with this servicing.
Thank you so much for that number! I called and a technician is coming out in the next couple days! I had already bought the capacitor kit, but oh well, maybe I'll need them in the future.

Thank you so much for posting that information. I just called and the serviceman is coming out on Thursday. 100% legit. Now my boyfriend is sad because he has no good excuse to buy a new telly. :-)
Thank you for posting this! I called Samsung and they sent out a repairman at no cost to me (Canadians have to call Samsung Canada). My TV is working fine now but the repair guy said the capacitors will blow out again after a few years.

That number is 100% legit

Thanks you so much sstiefel. The lady was great and as long as your model is on that chart I posted then it's 100% free. My tv is a LN46A550 and on the list she said within 2 days the service center will call to come to my home. It will cover Power Supply and capacitor repair. I am very good with a solder iron so I was totally willing to do the repair but, I'll let them.

What sux for me I bought my tv 3yrs and 7 months ago and bought the 3 yr replacement plan I could have gotten a brand new tv if this happened a little sooner.

UPDATE (12/10/2014): The capacitor warranty mentioned below, which was provided by Samsung, ended in late 2013 or early 2014. The issue with my LN46A650A1F just started happening last weekend (12/7/2014). So the website and # below in previous posts are no longer active. But by me being persistent, Samsung agreed to cover the parts and labor. Here's how:

I called Samsung support at (800) 726-7864. The first support tech transferred me to an executive support tech. That tech refused to cover the parts & labor since it was out of warranty, but he confirmed by me serial # that my TV would have been covered if the warranty settlement date hadn't passed. When I was persistent and said I read good things about Samsung's customer service online regarding this issue, he transferred me to a capacitor support tech (now we're getting somewhere!). This third tech offered me a "one time service courtesy" to cover the cost of the new capacitor and power supply. When I asked if the labor was previously covered under the capacitor warranty settlement, she said it was. So naturally, I requested that too. After placing me on hold to ask her supervisor, they agreed to cover BOTH the parts AND the labor. So Samsung stepped up and did the right thing, which I would expect them to do since they sold customers faulty equipment in the first place. But it took some persistence on my part, and a little bit of patience and pushing with asking the right questions to get this fully taken care of by Samsung.

Thanks so much ! The information was perfect :)

Not sure if anyone will respond as I seem to be posting a few years later than most. Bought a second hand Samsung LCD tv for my sister. The people selling it had it running when I came to view it and all seemed perfect. Went to turn it on the following day at home and discovered this problem. Feeling rather aggrieved at being hoodwinked but was delighted to find this site. However, my problem seems to be the taller components that are covered in blue rubber insulation type thing beside the capacitors as one is leaking, rather than the capacitors themselves, as they all seem fine. What are these components called? (They don't appear in any of the repair kits available on ebay etc) Any help would be greatly appreciated.

Thanks so much for this post. Our TV would not turn on and after researching on line as to reason, I found your post. We thought what did we have to lose. Disassembled the tv (hubby has some experience with this kind of stuff) and found the two puffed up capacitors (see bottom two of the 4 in pic) and ordered from what looked like a reputable place on Ebay for $2.59. Installed them and everything is great; no reset required. I had been having trouble for years with it turning off properly too so maybe something had been bad for a long time. Much cheaper than a new tv or taking to a repair shop.

Seconded on Samsung ending the settlement benefits as of September 2013. They offered to cover the parts (what, a whole 6 cents worth maybe?) and I would pay the service fee (which amounted to $200 for in-home, $150 if I brought it into their shop) so I said screw that! I had some caps I mis-ordered once (BIG 50V 1000uF instead of the usual tiny ones I usually order) and a soldering iron and a screwdriver. As luck would have it, the only two poorly rated (i.e. <25V) and damaged caps were 1000uF so I desoldered them (yay for that solder-sucker I bought) and dropped the new ones in and have a brand-new TV again after a half hour of work! Thanks for the instructable!

Oh, and if you need capacitors, don't go to eBay or radioshack or even mouser or digikey, go to Cheapest components evah

Worth noting that there is a component set for some Samsung power boards available on eBay. It consists of a few components that commonly fail and result in the TV not coming on at all (rather than the 10-20 minute delays some experience).

I have removed all the screws from the TV but having trouble removing the back panel. All the edges come up but something is holding it in the middle lower area. Any help?

Nice one sir, just replaced the only two 10A capacitors and got a load of spares. One note to add is my TV still showed the same symptoms until I ran a factory reset:

US sets: Power into standby mode, Mute, 1, 8, 2, Power
European sets: Power into standby mode, Info, Menu, Mute, Power

Mine is in UK and bought in Spain. Second one worked for me. Go to the first menu item and choose a factory reset. This will power down the TV and power it back up again. Choose 'Home' and it will be like a new TV.

Just basically got myself some knowledge and a great TV for £24.36 ;-)

New power supply board was put in and tv is not coming on. Do you push all buttons to factory reset. Mute, 1,8,2, Power?

Yes maybe this is enough but you may need to reset the EEPROM too by bridging 2 pins. I still have one cap somewhere to do (I think near the plug) but still trying to find time to get it about 15min of tv at the moment before malfunction acts up again!.

Excellent stuff this info, £1.18 for 2 caps, 1/2 an hour with a soldering iron and weeks of frustration (and waiting!) have disappeared. I'm a complete novice at this sort of stuff, but your instructions were dead easy to follow, cheers.

Purchased some new capacitors on EBay and performed the repair myself thanks to your detailed instructions. Thankfully not a high degree of difficulty. Hardest part was melting the old solder and removing the defective caps. Once that was completed, installing the new ones was a pretty straightforward (my occasionally poor aim with the new solder notwithstanding). Now the TV fires right up again. Thanks for posting!

I have the same problem with my Samsung TV, I have reached this step but cannot seem to locate any dodgy capacitors, All capacitors look undamaged and there is no liquid from any of these. How do I decided which ones to replace?
sshipway alelex10 months ago

Since they are cheap, if you're not sure which are the failing ones, I'd say just replace all the 1000uF caps to be on the safe side.

I called Samsung twice and found out that even though my TV is on the list, they can't help me because I purchased my TV in 5/09 and also the class action lawsuit settlement ended 9/13. I am awaiting a call from their service center to get an estimate on repairs. The last person I spoke with told me it could be an issue with other parts like the main board, power supply, etc. I think it is the capacitor issue because my TV is clicking when first turned on and works just fine when on. I have told them that I own 2 Samsung TV's and the older model works just fine and If I have to pay for repairs because of a manufacturing problem (e.g. poor capacitors) , I will never buy another Samsung TV. Also I'm not working and paying money for a repair due to bad capacitors is a real downer!

Spent £1.18 on two new capacitors and repaired myself: avoided splashing out for an expensive shop repair or even more expensive replacement TV. Makes you wonder how many other everyday electronic products can be fixed DIY. Most satisfying

derektool1 year ago
This worked for me. I bought the only capacitors that I could get my hands on (radioshack 1000uF, 35V, 85degC, radial) and replaced the 2X 10V and 2X 25V that were bulging the most or leaking black fluid. TV has worked for a day so far. Fingers crossed...
I have a Samsung HP-S4253 42-Inch Plasma HDTV and it will not turn on at all. The Blue light on the front is on but will not actually come on. Can someone please help.

Hi everyone, just an update. I'm from the uk. Have same problem with the clicking before turning on. Unfortunately my extended warranty has run out. However I called the 888 number which directed me to another number.

The person said that the action and the outcome of repairing per 2008 models was only in America and not in the Uk. Great eh, a genuine problem accepted and repaired in one country but not another.

Anyway, I said to the person that if Samsung won't repair then ok, I will follow the instructions on this site. I was given a number 0932 454 385. From past experience I know this to be a premium telephone number which cost a fortune the longer you are on it. The person said she will get someone to call me by 12 noon today.

I don't have any great hope so I will start getting the parts together for my own repair. Will update later if anything happens

Sir! Respect!
I thought I was going to have to spend my pension on a new TV (The Samsung was well out of warranty) but- 5 minutes to find your advice, £2.29 spent on two caps at RF Potts in Derby, maybe half an hour doing the job. And my wife thinks I'm a genius! Forgive me if I don't disillusion her: I know where the genius lies. Very happy man here. Thank you.

As an FYI to Americans reading this, there are several online electronic component retailers available. I've used these, Allied electronics (, Newark (, and Mouser ( The capacitors in question average $10 U.S., shipped for 5 units.

just yesterday 4-7-13 my Samsung 52" 630 series started freaking out when I turned it on. I bought this tv on 12-31-08 so I've had it awhile now and has been trouble free until yesterday. today I figured i'd go online to see if I can find a common solution to the start up glitch and I stumble upon this site and learn there was a class action suit and a manufacturing problem and it so happens I purchased my tv at the cutoff point of the recall. I call Samsung and gave my info and they are sending out a repair tech on the 10th, no charge! that's cool! my wife says "wow, what a stroke of luck"....uh huh! just thought i'd post my experience to let the doubting Thomas' know that this is legit but your fix time is running out! anyway thx a million guys, probably saved me a couple of hundred $$$! gil h

Thanks so much for this information. I've been googling this issue and found many people with the same problem. I came across this site, and found the info regarding the Samsung settlement. My model is on the list, I called the number below, and was given a Repair contact. He came out this morning and replaced the board with the bad capacitor (he could see immediately it was bad), and just like that my TV is working.

It took all of 10 minutes to fix it. Great support, although it was unfortunate that I had to poke around online so much to find out about the Settlement. I'm sure there are many people out there who have no idea.

Hey thanks so much for posting this. My TV wasn't on the list for the recall, but the woman at Samsung essentially admitted that maybe only half of the models that should be on the list, are on the list. The repair shop quoted me at least $200. Anyway, my boards looked slightly different than yours, and my underrated caps didn't look totally blown, but they were clearly different from the rest, different brand and at lower rated voltage. So I replaced them with 25-V ones (like all the others) and it works well now. For Americans, get your caps from DigiKey online ($1-2 each.)

Best part of the deal: I did it with my son, who did the actual soldering since he has steadier hands than me. That was his first time soldering. He is quite proud of himself and old Dad seems a bit less the doddering old fool.

Thanks again!

My tv is one of the listed models. I called the number listed in other posts. my call was answered quickly. I was given a service # and the name of a repair shop within a few minutes of my home that would look at the tv and make the repairs free of charge. So far this process has been quick and painless!

Hi Damp,
My Samsung 46" did the same thing, or so I thought. I called Samsung, they said it was the capacitor problem and sent a service guy to fix it. He came, looked at the caps, and said they were perfect and that the caps weren't the problem. He said it was the 'mother board' which wasn't covered by Samsung and would cost approx $300 CDN to fix. Well he got the 'mother' part right.

TV takes about 15 mins to turn on. It cycles thru the power on/off cycle once a minute and at first shows a black screen, then shows some rectangular patches of white in random locations, then starts screeching with green lines all the while cycling on and off every minute. Eventually the picture shows and the TV stays on and works perfectly. I'm tempted just to leave it on.

Once it's working I can usually power it off and on if it's within an hour, otherwise gotta go thru the same process again.

I read somewhere that the capacitors could be 'blown' and still look perfect.

Any suggestions.

I have a Samsung Series 5 LCD TV that I picked up about 4 years ago. It went from a 30 second startup time to not turning on at all in a matter of 3 days. Checking the inside for the faulty capacitors I immedately saw the bulging ones. There were 2x'1000uF 25V 105C' and 2x'1000uF 10V 105C' capacitors out of which only the 25V ones were bulging. The 10V capacitors looked just fine. But, I replaced them anyways.

I picked up 4 '1000uF 25V 105C' capacitors from a local electronics store for a whopping total of $5.5. That's BD2 for anybody in Bahrain reading this. Having already had all the tools in my toolbox it took me less than 1 hour to go through the entire process and that's with me taking my sweet time.

End result: YAY! Working TV.

P.S.: It might just be because I fixed it myself, but the picture looks clearer and the colors look brighter.
