Hi.

If there is no power at all, then you have blown the power board.

If the backlight comes on, and suddenly shuts down, then it is usually the inverter board, sometimes a faulty power board.

Parts must be tested before replacement.

Parts are available at Replacement TV Parts
Before replacement parts must be tested.

It will also be good calling Sanyo at the number listed on the owners manual to get a quote on repair.

Let me know if you have further questions.

Regards.

Sanyo DP32746 screen black no sound screen flashes when turned on


Hello, I just posted this to another user's question, and you might find it useful, too.

I have a pile of these in my shop. Unfortunately and usually, a backlight lamp is bad, and the inverter board is damaged when it goes out. The backlight lamps are sealed inside the panel, so the usual method of repair is to replace the panel.
If you turn the lights off in the room, then turn the tv on, you will probably see a momentary flash of light from the backlight trying to start up. The lamps can be replaced, but the option is not really cost effective given the amount of time it takes to replace them/very delicate nature of the lamps/availability of the lamps/cost of the lamps. Replacement panels might be available, but you'd have to use a TV shop for reference or call Sanyo directly.
These units also have a history of power supply heat damage, so if you don't see the momentary flash, it could be the power supply. But the momentary flash is the dead giveaway.

I hope this helps you...
