TV powers on, Green power light remains green. No picture and no sound. If you press the menu button or try to change channel, TV screen will flash large red blotches but nothing else.
The line output section circuit works as soon as you switch ON the TV, and then come across any short circuit inside the set, and shuts off. That is happening here now. You must check the set, and trace out this shorted or damaged component/s. If you're sound in electronics, download the repair manual to this model set by internet, and carry on. If you're not sound in electronics, contact any service technician. If you wish to get some details about repair work, check the site linked here.

This is a bad power supply and an easy fix. Their are several electrolytic capacitors on the power supply. If one is bad it will have a bulge on the top. Mine had a bad 2200uF and a bad 1200uF capacitor. About $7 worth of parts at Radio Shack. Radio Shack had the 2200uF but it was axial leads instead of radial. (leads come out of each end instead of one end) but It will still fit. They only had a 1000uf capacitor so I combined that with a 220uF capacitor and wired them in parallel. Make sure you put them in with the correct polarity.

Unplug and replug it...it should work eventually.
I have the same problem with my 32".
But it eventually goes on when i try it a couple of times (the number of times is completely random...sometimes none, and sometimes like, 3).
