Projector projects with pink tint

My Sanyo PLC-XU47 Multimedia Projector has developed a problem where the image it projects has a permanent pink tint. This occurs when a computer is attached, but is not present when the projector is displaying its 'idle' screen before a computer is attached. The lamp replace warning light has not come on so it does not appear to be a problem with the lamp bulb. Can anyone please help?

    I have a PLC-XU48 and there is blue tint that covers about 1/2 of the screen. When the screen is showing black I can still see an obvious blue tint. I have read that a lamp change may not fix this. Any Ideas?

    I also have the Sanyo PLC-XU48 and just swapped out three hundred bucks worth of replacement lamp to find this isn't an unknown problem.

    I have an Epson Powerlite 745c which shows a pink tint as if the red color had been turned up and the blue and green left down, but when i went to the color adjustments it did not match what i was seeing so there is an obvious problem with either the lamp or the lens's. Does anyone know a solution to this pink tint besides replacing the lamp??? I'd rather not have to go buy a new lamp when the one i have still works. I was able to adjust the color manually so that the pinkish color sort of went away and the blue stood out more, but this still didn't look at full quality as it is supposed to. Any help or suggestions would be great.

When the image turns pink, we find that replacing the cable between the projector and the lap top fixes the problem.

No focus

lamp isn't striking. either the lamp is blown (check for burn spots or cracks) or the ballast isn't firing the lamp. either way, one of them need replacing.

The filters are starting to show their age. This is a normal occurance for projectors and is the result of heat. The filters and/or the mirrors might need to be changed.

If you accidentally lock the projector, you need to disconnect the AC power cord. Then HOLD the SELECT button at the same time as reconnecting the AC power cord again.

This should reset the lock out.

Tinted image

If you are plugging in a monitor cable, it is most likely a cable issue. I would try another cable and make sure the cable is seated firmly into the projector. If that doesn't help, check the port on the projector for bent or missing pins because it seems that not all of the video information is reaching the unit.
