LCD projector 101, your blue device is dying inside of projector. Consider purchasing a dlp based product, they do not suffer from color decay.

Really you are blessed , most lcds last about 3-4000 hours or 4 lamp changes. good luck

This is power supply problem.
1. First u replaced the power out put capacitors , 6V, 12V, etc.
2. cheak the diodes.

when you leave your TV (no matter what kind) and you leave it for long periods of time on a static image or something.. the image tends to burn in to the screen... so changing the glass would be a way to fix it.... the problem is that that kind of repairmen is more expensive and difficult than buying a new set...
