Hello, I have a Mitsubishi WS 65908 rear projection tv. I have HD tv and have noticed some color distortion on the left and right 5" of the screen. Whenever the entire screen is being displayed the left and right 5" of the screen have much better and clearer picture quality than the rest of the screen. Non high def pictures do not use the left and right 5" of the screen. Is anyone familiar with this? Your help is most appreciated. Thanks, Brian

Since yours is a CRT RP set, I'd guess that the phosphor on the CRTs has seen less use in the SD blacked out areas on the sides and is "fresher" there. Some source devices allow you to make the bands grey in appearance and thus use the entire screen equally.

One more thing - have you cleaned the projection lenses lately? Dirty lenses will really degrade performance.

Thanks BANDB. I have cleaned the projection lenses after this started and still the same. I think it has to do with your first reply. The areas that are clearer (outer 5" of each side of the screen) is less used than the rest of the screen. Those areas are only used when the video source is HD. Is there something that the above average joe can replace, clean or try? Brian

The only thing to correct that is the replacement of the CRTs; which a too much expensive choice.

You might try viewing SD in 'stretch' format to fill the screen and hope the phosphor wear (if that is the problem) eventually equalizes. Using a calibration DVD might help you mitigate the problem a bit. Replacing the CRTs is a place you probably don't want to go.
Good luck!
