Occasional discoloring, tv randomly turns from green tint to no tint
When I turn my tv on, the screen will have a green tint for about 15-30 minutes and then it snaps back to normal. It is not always constant, sometimes it will revert back to green several times before staying tintless, and sometimes it will never change from green. I checked all my other elctronics, and im sure it is not interference. I have an Insignia is-tv040922 25" color tv a little over a year old.
When the tv is tintless it looks fine, but when the tint is on the white appears to be yellow and blues look green. It almosts acts like a wire is loose but banging on the tv seems to have no effect on the tint.

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.
you have a shorted green CRT that is affecting the other crts the short is internat to the crt that leaves what is called retrace lines. if the set is more than three years old then replace all three guns.
Turn down your color and see if the screen has a normal black & white screen. If it doesn't then the CRT is bad (picture tube). If it is black & White then you have a either lost your red or blue.That problem will be in your video driver circuit of which a service center can handle.
Jar-Head, bad news, the picture tube has a mild short in the green cathode, tech can come out and try to restore it but it`s usually a futile attempt on sony tubes, sorry to be the bearer of bad news, BMW Rider
green tint & screen dark means that there is a problem in green video circuit.
1 check green video supply .
2 components in green video ckt.
3 adjustment in green video section.
4 check for signal to green video.
I would check the green signal all the wat to the display screen to determine is this is a signal problem or a system short. I would recommend that you take this set to a qualified electronics technician
