Question about Akai LCT2662 Television
Thanks for the advice, premtech. My LCT 2662 finally died from power supply problems after about two and a half years of use (it started giving us problems about six months ago). After reading the fixya.com recommendations to replace the capacitors on the power board, I decided to give it a try. I took the back off and was grateful to find the power board to be easily accessible. It was immediately apparent that several of the 2200uf capacitors had all bled out. There was crusty brown dielectric everywhere! The 1000uf appeared to be in good shape, but I ordered a new set of those anyway, along with the 2200uf/25v caps as well. I replaced all of the 2200uf caps first, since they were pretty much all fried, and tried the set out. The red power light came on, but when turning the unit on, I would just get a momentary flicker of the main screen, then nothing. After poking around the power board some more, I noticed that the four 3300uf caps also look to have melted out. So it was back to the Jameco website to order more parts. After replacing those four caps, the tv mercifully came back to life and has worked like new for about an hour now. I did not have to replace any of the 1000uf caps, but who knows how long the original ones will last. Oh well, I have to parts and know how to fix them if they do burn out. Thanks to all those who suggested the fixes. You sure know your stuff!

Power supply most likely... It's a common problem with this particular model and we've seen quite a number of them for exactly what you're describing.
You need to replace 19 caps in the power supply 4) 3300uf/35v, 8) 2200uf/25v, 6) 1000uf/10v, 1) 1000uf/16v and you can go a little higher in the voltage of each cap for greater reliability.
It's best to have an ESR meter also and test the remaining caps as well.
