Question about Samsung LN-S4051D 40 in. LCD Television
Where can I purchase new IP Board (power board) and I PCB Board (main board)
I had the same problem. I work for a mother board manufacturer w/offices in New Jersey and brought mine into our engineering lab after Samsung told me tough luck. Anyway, one of my engineers fixed it in 10 minutes. Essentially, he replaced the 1000uF capacitors on the power supply board with 2 cent capacitors instead of the 1 cent capacitors that had blown out on the CHEAP SAMSUNG POWER SUPPLY BOARD. You can tell the caps are blown via visual inspection. The top of the cap should be perfectly flat and a blown cap will be convex on top. Unfortunately, there are also 2500 uF caps by the same cheap manufacturer on the board as well and we don\'t stock that value for our products. According to my engineer, those will most likely blow next since he replaced the others with better caps, but I\'m getting samples of those and will replace them shortly. After that this piece of junk should last me at least another 2 yrs! It\'s been working for about a week now w/no problems. Hope this helps.

Thanks everyone for the helpful tips on the bad capacitors. I opened the back of my LNT4042HX and there were the bad capacitors plain as day CM806, 811, 812 & 817 plus i had 1 more bad one # 807 which the top was bulging, so i replaced all 5 with 1000uF 35v capacitors from Radio Shack. It took about an hour to do the entire job and my TV was up and running again. Or should I say turning off & on like its suppose to "With The Power Button" ;) Life is good once again :D

Anybody who has bought a Samsung LCD tv in the last few years and is having problems with it not turning on or making clicking noises when it tries to switch on can get it repaired for free by Samsung, even if it is out of warranty. Mine started to go wrong a couple of weeks ago. I had the clicking problems and also a green overcast on the screen. I called Samsung and it was repaired within 3 days free of charge. Call 01932 454358 Samsung. The engineer said the fault is because the wrong components were fitted to the televisions in the factory.

Had the same problem with my LA40R71BDX. After stumbling upon this thread (luckily) I've saved myself at least AU$500. The same capacitors described by everyone else (CM806, 811, 812 & 817) were bulging and two had black stains on the top. Replaced those with 1000uf 16v capacitors (as the 35v ones i'd prev bought were too big) screwed it all back together and presto! worked first go! Thanks to everyone on this page, you've been great! Oh and by the way, if you are thinking about doing this and haven't done ANYTHING like this before (i.e. Soldering, electrical work) I suggest you take the risk. I had no experience before this and it was a breeze. There is a youtube video on how to replace these exact caps on a 52 inch LCD samsung... Just search samsung tv repair. Thanks again!

Thanks guys, my Samsung LNT 4061 had the same problem, after 1 year and a half. I called Samsung and they told me that I was on my own (CANADA). After reading the Forum i bought the capacitors 7.25 dollars. replaced it and it is working again.

SO GLAD I STUMBLED ON THIS THREAD!!!
Same problem, clicking sounds...no picture on my beloved Samsung LCD tv. I opened it up, and sure enough, those same four capacitors were blown on mine as well (including the burn-mark on a nearby ribben). Uncanny. I've never dealt with this sort of thing before, but on close inspection ONLY these 4 capacitors were not flat on top, and three of them had black marks on them as well. Went to Radio Shack, bought the replacements described above, as well as a $8 solder iron kit (which came with solder as well) and in about 30 minutes had replaced all four capacitors. There are lots of helpful how-to YouTube videos on how to solder if you have never done it. My TV is back to perfect working order AND I learned how to solder. Not bad for a days work!

I had the same problem and found a board for 112 dollars shipped on the internet. Two days after I ordered the board the TV is on and working. The IP board # BN44-00134A for a LNS4501 samsung. I purchased it from partstore.com.

OMG!!! We just changed the 4 capacitors and it WORKS!!! No a hesitation, no problems at all. I\'m floored that this worked. It cost $6 t o fix!!! Screw Samsung and Best Buy for trying to get hundreds of dollars to fix this. As a quick note, I have never worked on anything electrical, and this was so easy. Check out this youtube video on how to fix. http://www.youtube.com/watch?v=8l0AUj8QUkg

I've just found a solution to everyone's problem!!!! Just like scores of you, my Samsung tv has the same fault...Go to Sale of Goods Act 1979 (as amended) Forget the 12month warranty....We have 6 years in which to claim replacement/refund; and it is the seller not the manufacturer who is liable..I've just sent my retailer the facts and hey presto instant reply to make things right...Go for it...good luck!xx.

My Samsung LN-T4061F TV was taking more than 2 minutes to power up while it power cycled several times. After it finally powered up, it would work fine. I called Samsung and they said it was related to the capacitor problem and that they would fix it for free. A repairman replaced five capacitors, two of which had popped the top . The repairman said that the problem was that since the capacitors were close to a heat sink, they needed to be rated for a higher temperature. The capacitors that he removed were rated for 105 degrees Celsius, but I didn't see the ratings on the replacement caps. He also said that the time limit for getting the repair for free was almost over, but I think the deadline depends on when you bought the TV. After the repair, the TV powers up in about 5 seconds and works like new.

I have a burned out capacitor as well; however, it has 2200 uf (10V) on it. It also has 115 degrees C as a rating. I'm nervous about buying different capacitors at Radio Shack...what should I do?
Also, I just noticed ONE capacitor that was bulged/burned; the others looked fine. Should I replace all the other capacitors as well?
