REd background instead of black

I have a Panasonic PT-LC75U LCD projector. When I power it up the screen is red. When I go through the menu to the background it is saying that it is black but it is red. What would cause this to happen?

Re: REd background instead of black

It is low voltage in the screen driver board, probably a bad capacitor in the screen driver board or perhaps in the main power supply. The only way to tell would be to look at a schematic and measure the voltage and check the voltage source on the power supply board. If the voltage was low, replacing the board should fix your problem. If the voltage was normal at the power supply, then the screen driver board would need to be replaced. Good Luck

Red spot on HDTV

This is a LCD projection TV and will need to have the light engine replaced. Hopefully you have a warranty on it or it is still covered by Panasonic.
