I'd like you to turn the color all the way down and let me know if the over-all picture looks Black&White or as we call it gray. Did this just happen or has it been changing over time?

I took the back of the tv off and the blue lamp is not bright like the red and green. Could this be a coolant problem or lamp. I have the PT5492S Akai rear projection TV.


The blue is usually dimmer than the other two lens; what I would suggest is try to look into the lens with the set on; BE CAREFUL AND NOT TOUCH ANYTHING INSIDE THE SET.

If the red and green show a picture but the blue looks like a floodlight you have bad Glycol in the blue tube (common in these sets).

If all have a normal picture remember to wipe the lens clean at the top; do not try to take the lens etc apart.

Before you rate this information let me know what you find.

This could be one of many different issues. Main flaw with these units are as follows:

Blue picture tube leaks coolant onto neck board and mainboard causing problems.
