check your LCD inverter maybe there is loss connection or some parts damage from inverter.
SOURCE: Screen goes black, still have audio
I first changed the 220uf capacitor with no luck. I flipped the BURN switch to on and the set has been working great for a week now. Daughter left it on for about 20 hours overnight with no problem. Anybody have an idea what those 4 tiny switches are for? I have heard these type of switches called "dip switches". They are tiny white switches in a yellow block on the lower left side of the upper circuit board. The top one was labled 40", the next one down was labled 46", the 3rd one was 4 letters "EW" something I think, and then the bottom one was labled "BURN".

something overheats inside your set, causing it to turn off before causing more damage. please have your set inspected by a certified technician.

The common issue with polariod is there power supplies, Your going to have to fork out something for the repair if you not willing to buy a new TV here, A new board in this would be $175 labor another $80 or $90 tops. So you getting into $250 fast. This is why I say to all my askers NEXT TIME buy a extended warranty.
