    TV turned on and was running fine for about 15 minutes when it suddenly turned to a green screen. Picture is still slightly visable through the green. Have tried adjusting the color, brightness, etc with no results. Is there anything I can do short of taking it to a technician to fix it?

To clarify the repair the video board sets upright verticile that plugs onto the (main board) horizontal with locking tabs just lift up off clean pins with emery board spray socket with abrasive cleaner called (blue stuff )
I also checked for bad solder connections on the crt board and resoldered some connections on main board where the pins go in to the upright video board I hope this clarification is more complete

If you can still see the video and some fine white lines running diagnally across the screen, it is very likely the picture tube itself which would likely be covered under warranty. If it is a solid green screen with no video, it could be a defective driver transistor or IC going to the picture tube.

Green tint I can't seem to fix

Hopefully someone on here has a manual and can tell you exactly where the tint controls are. Also need to try adjusting the color level, turn it clear down so you have a black and white picture.
Is the picture still green over the screen with the color control
set clear down to black and white? If it does, you might
have an issue with the green gun going out or problem in the
circuitry to it.


By the way, the best way to adjust the picture settings on a
tv are to first turn the color control clear down, then adjust
brightness and contrast for best black and white picture, then
bring up the color level to where it should be and adjust the
tint for best red/green ratio.
