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...
