Older hitachi bigscreen tv shows picture. Screen would turn light green you can still see the picture though and then it would go away and then all of a sudden it doesn't go away anymore

SOURCE: hitachi rear projection tv. screen looks green

Green CRT bad = take off lower front cover, remove access panel
locate screen / focus block.....turn green screen control slightly
CCW............................re-assemble...........T.

SOURCE: No picture, but power is on...

How many times does the POWER led blink per sec? (dont worry about the OPC)

2x = power supply (not as expensive to fix)
3x = Main board (expensive to fix)

SOURCE: flashing red light

I think this sounds like my problem (need to replace the projector lamp). However, when I hit the "on" button, my SXRD 50" blinks green for about a minute then starts blinking red. Can you confirm the bulb solution? I was very pleased with this sight when my fan malfunctioned. I got the fan in a matter of day's from Sony and it fixed that problem.

SOURCE: My hitachi 50VS69A tv shows the picture green.

A green image is usually due to a lack of red or especially blue. the problem is becoming all too common with hitachi lcd projection sets. what happens is that one of the lenses in the optical block (or light engine) starts to burn or discolor due to overheating because of a blocked air filter causing poor air (cooling) circulation. Nothing can be done when the damage is too far gone except to replace the light engine-at acost that makes it not worth repair. if the damage is minimal than to reduce further damage the air filter should be replaced. Light engine needsto be removed in order to replace the air filter.
