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.

My toshiba 61h71 has a reddish tint to it. Turned it off one night and it looked fine, next morning it got this reddish tint. Tried resetting the convergence but that didn't change the situation at all....


A Reddish tint means that the Green signal is missing. Does the on screen menu look normal? If so, this points to the signal source. The fact that this happend suddenly, I would check your cables first.
Using YUV?
If the TV's Menu also looks reddish then there is an internal problem with the display.
Good luck

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.

Green tint on screen


Is it a green tint at some areas alone, oris the entire image having a green tint? If it is a color patch at the corner or other areas of the screen, in all likelihood it is a degaussing problem. Color patches happen when the TV is moved from one location to another, or if some magnetic source is placed close to a CTV. Did you put a radio or Tape recorder or Walkie talkie toy or any magnetic source near the TV? if yes, remove it. And the automatic Dregaussing circuits in the TV will resolve the problem in a couple of days. But if there is an overall Green tint on the picture, it signifies a problem in the Video output stages, and there is nothing you can do, but call the technician (unless you know solid state servicing?)
