The picture has a green tint to it on all channels


The color signal consists of Red, Green and Blue. Those three colors, at various degrees, make all the other colors on your screen.

If you have a BRIGHT green screen it's best you don't operate your set.
If it's just tinted green then there is a problem on the CRT (Cathode Ray Tube) drive board. Do check your "tint" setting and see if someone misadjusted it. If that isn't it then you need to have your set on an electronics bench and get an estimate for repair.

Hi

First check whether all the cables from your dishnetwork are fine and connected firmly.If yes then you'll need to pull off the front of the tv, behind the speaker grill there would be a panel. Remove the panel and check for a black box hanging over there. It has 6 controls on it, 3 are marked as focus and 3 as screen. You'll need to adjust the screen. If you turn these too high you can damage a tube. so we are doing real small adjustments. Turn the color off on the tv and adjust the red, blue & green controls up till you get a fine picture. Also adjust the focus until you get a clear picture.

And, if it doesn't resolve your issue then it is an intermittant blue picture tube, a bad blue driver transistor on the CRT board, a bad connection on the blue crt board, or a problem in the RGB coming from the video jungle IC. A set this age, most likely will run you about 300 to 500 bucks to have this problem fixed, unless it is the picture tube.

Please do accept this solution and revert for further assistance.

Thanks
Rylee
