Recently replaced the Filter and Lamp, worked great for a couple of weeks. Now the color red is very dark, almost black. Settings for contrast, brightness and color have been adjusted, and reset to default. Changes do occur, but the color red is never restored.
I hope its on warranty because that sounds like a circuit board problem. Was the replaced lamp the original specification?

To reset the lamp timer:
1) With the projector plugged in and turned off, press the 'ON/STANDBY' button to put the projector in 'STANDBY' mode. NOTE: You have to press the button on the projector itself, you cannot use the remote for this step (this is not clear in manual).
2) Now, using the remote, press the following keys in order: RESET, <--, -->, ENTER.
3) Timer should now read '0'.

I think that projector used three different LCD panels with red, blue and yellow. You probably have a damaged red LCD panel, and if so, it is not worth getting the projector fixed. Those panels were really expensive back then.
I once had that red problem with a projector and it turned out to be a bad connection on one end of the "computer to projector" cable. Borrow one from a friend and see if it solves the problem.

There is a small tab on the lamp cover that should press into an "L" shaped slot on the lamp housing. This tab may break off, and not press into slot far enough to make the lamp dectection switch click. When the lamp heats up, the plastics expand and the detection switch opens. The projector quits as if no lamp is installed. The fix is to make an extension for the tab. I cut a small piece of sheet metal and crazy-glued it to what was left of the plasic tab.

since it has worked 1200 hours or even more since u have been resetting the counter! just change the lamp, resetting the counter does not make the lamp work or not work , it is only a reminder for the user to change the bulb when it should be & that u have some balance hours left to procure a new lamp!
if the brightness is adequate, then it is a ballast problem & not lamp problem!
buy a new lamp as u will anyway need to , fit it & it may solve ur problems permanently!
