Grayscale. Could be in the Screen trimpots of the focus block as well.

Need an ISF calibration and/or rebalancing of the Screen trimpots.

Lower the contrast first.

If colors not in balance, reduce saturation until "normal" to your eye with whichever color (or color pair) out of balance.

Bad color


Turn the color level all the way down and see if you have a good black and white picture. If your screen isnt black and white it should have a predominate tint to it. then turn the screen control for that color down to achieve the best black and white picture. then adjust your color level that should help.

Green picture


Hi,
I'm not sure about this model but most projection tv's have a focus/screen control block usually located behind the front grille where the speakers are. The grille usually comes off easily. If there are no circuit problems you can adjust the red green and blue picture tubes there. Also the focus. It will be written somewhere screen and focus: Three for screen and three for focus. If you find the screens then adjust them slowly clockwise for increase brightness on the red and blue and you may have to reduce the green. Adjust for best picture. If the picture does not adjust too good then the tubes are weak. Only if there are no circuit problems Hope this helps
