    TV has a yellow tint. We have tried to adjust all picture adjustments and nothing works.

    where is the coolant containers located on the TV? Where do you get the replacement coolant. I don't believe our menu has a convergence adjust.

Check the coolant in all three crt's as chances are it is contaminated (should be crystal clear). If brown (beer color), replace coolant in all three crt's and perform convergence adjust. Picture should be like new!!!

Good Luck!!!

BLUE TINT ON MY SCREEN


Philips tv's have always had this problem. Between the picture tube and focus lens there is a layer of coolant fluid. The coolant fluid, over time, will break down and turn a brownish cloudy color and it usually starts with the blue. Something to do with the color frequency. Have a good repair shop check it out and if the fluid is the problem have them change all the fluid in all 3 picture tubes (there is a red, green and blue tube). Don't feel bad, like I said all the philips projo's had this problem. Thanks

There is a green tint to my screen. Seems to be more evident in dark shows and on shadows.


Pull the front speaker grille off and remove the access panel. In the customer menu turn the color off so you have a black and white picture. get a flashlight and adjust the screen controls for the red, green and blue tubes until you get a nice black and white picture. then turn the color back up.

Color problem


use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.
