1 Answer

The power button lights up but no sound or picture.

I have a Sanyo 32 inch digital lcd flat screen. When I turn the power button on, the green light lights up but no sound or picture. This is the third time in a week and a half this has happened. Normally it will come on after a few minutes but not this time.

Check to see if the set is under warranty or an extended warranty.

If not, ouch, but do-able.
From least to worst case, possibilities include

1. Bad panel drivers (between the Y-Sus PCB and Panel)
2. Bad Y-Sustain board or equivalent.
3. Bad power supply.
4. Control PCB.
5. Bad Panel.

Or any combination of...

I would recommend that you have a certified and factory authorized technician repair your set. Or at least diagnose it. Not always is it just replacing a board. There are adjustments that need to at least be verified by a knowledgeable technician.
Wouldn't want to get zapped. There is High Voltage back there.
You might also try entering the make and model number of your set online to search for others with like problems on the same model. Odds are that it has happened more than just once and that other techs may have a definate solution to your problem.
Just takes a little research.
Good luck.

Green light blinks but no sound no picture


Power surge will knock out picture and sound if you don't have a power strip. Found out from Best Buys when purchasing another LCD TV. They have a warrenty against such problems.
