My quick and easy solution was to clean the dust off the lenses of each CRT.

1) Unplug TV
2) Remove the back panel.
3) Wipe each of the three (plastic!) lenses lightly, with a lint-free microfiber lens cloth. Do not use anything that might scratch the plastic lenses.

Other than that, you'll need to hire someone to adjust your gray scale tracking.

Just replaced color wheel. When TV turned on seemed fine but then i noticed a grey/black shadow band on one side. What could be the cause?


I had a similar issue with mine from the factory. There was a grey/black shadow in the upper left. Called for repair. The guy took off the circular access panel on the left back side and there was a fingerprint on the projection lense. He cleaned it and it disappeared. Sounds the same. Maybe touched the lense replacing the color wheel?

Projection tv 42" panosonic hdtv. to much green in the picture. Jeff


this unit may have a resistor on the green crt-board that has increased in value. check ohms(resistance) on all crt boards and compare to one another. these will have color bands that inicate value of resistance. you do not need to know color code, just match colors of resistors on each board then measure. you could also have weak green tube. turning down the master screen control located on the fous/screen block can reduce grn. drive. to adjust proper drive for each so the grey scale is correct, turn color to tv all the way down then adjust screen controls on block for black & white picture. when color is turned all the way down, you should not have any green, red, or blue over cast on screen. mch

Night time scenes have become almost impossible to see.


I had the same problem. Figured the 8 yr. old set was on it's last legs. Read everything I could find and nothing helped. But, luckly I did the following and it's like new again! try the following: Press MENU, selectSETUP, select DPO, set it OFF. DPO automatically controls Contrast, BLACK LEVEL (Brightness) and Color. Now press Menu, select PICTURE, then select BLACK LEVEL and run it out to plus 25. your picture should be brighter. Then adust Contrast,Color and Black level to your liking.
Good luck!

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.

Red , Green And Blue.


Heres the best way to set a phillips screen controls. Go into the picture controls and set picture or contrast to roughly 75%, then set brightness to 50% and then set the color level completely off. Then adjust the screen with the 3 color controls untill you recieve the best black and white picture as possible. If you are unable to achieve a good black and white picture change the coolant in the green and blue tubes. But if you can get a good black and white picture stop there then turn your color level back up and the picture should be correct. Let me know if you need further assistance.
