Have a Samsung lcd tv model LA46M81BDX. Same problems. TV started by not displaying DTV channels without turn off/turn on power. That worked for a few months. Then tv started to turn itself on at random – day/night. Then finally the clicking relay and no power up. Removed the back cover which was quite easy and exposed power board. Found the two low voltage electrolytic caps (2200uF) had bulged. Cost less than $5 to fix. Average soldering skills needed. Was prepared to toss the tv out at one stage.

Having the same issues as well, there is not a single raised capacitor on the power supply board, all the cacitors are fine.

Looked under the capacitors and still it remains a mistery because theres no leaking acid or bulge.

Appently capacitors can ‘dry up’.

I am having the won’t power up issue with a Samsung 32″ LN32A4 from Circuit City. Less than two years old, won’t power up, flashing red light on the front. Tried to do an online request for service and was sent to a walk in repair shop in New Jersey and I live in CA. Then called customer service was given a tech transaction and transferred to a personal services advocate representative. They said my unit wasn’t covered, I would have to ship it to them and give them a credit card deposit of $125 plus pay for the shipping. I will attempt the repair myself, but very bad customer service and would not recommend buying a Samsung if you are looking to purchase.

[...] capacitor is bulged or swollen and that’s how you can identify if the capacitor is bad. See more bad capacitor images Most of the post I have read online haven’t shown a capacitor that has leaked, but obviously [...]

I am one hour post do-it-yourself repair of my Samsung LCD and I have to be honest with you. . . . It is very simple. I have never done any kind of electrical work but was intrigued by all the stories of people fixing it themselves. I replaced four capacitors at .98 each. . . . EACH! Had I owned a sodering iron this repair would have only cost me $4.00. I encourage you all to give it a try. . . you will surprise yourself! Good Luck!

i can’t find the exact same capacitors that are on my tv.The caps on my samsung tv are 1000uf at 10volts and 105 degrees C.The only ones I can find locally are 1000uf at 16 volts and 85 degrees C.Will that difference in temperature work.
