The projection TV has 3 guns RED GREEN BLUE. In your case the red and the blue guns are gone. So you are getting the green color screen. You got to replace the picture tube.

Colours missing from tv


There are three color guns in a TV that make up the picture. Red, Green & Blue. It sounds like you have lost the green color gun.

You can get it rpeaired again, but your TV sounds like it is ready for TV heaven.

I have an RCA model 20F512T and the screen is tinted green


maybe you should check your picture settings from the menu button, it should be a "slider" from red to green, and your preference somewhere near the middle.

Green picture


a green screen on power up with retrace lines. At shut down a point appears in the middle of the screen. Sounds like either a shorted G2 grid, or bad flyback. If a phospher flake has shorted the grid in the tube, you can sometimes have luck by using a megger set at 1000VDC, to burn away the short. This is usually caused by the line HV going too high causing the anti-UV protection to kick in so fit a dummy load 40W lamp instead to the line output to allow measurements to be made.

TV just turns off


Most common reason for this problem is dry joints, ie cold/bad solder joints.
