Sometimes picture tube tvs develop shorts between the internal electrodes usually cathodes to filaments causing the one or more of the guns inside the tube to go high in emission, when this happens the screen or picture you see will get excessively in this case red and some horizontal diagonal lines will also show causing the tv to shut down, another condition that may cause an excessive red screen may be a failure of one of the voltage source that feeds the color amp in this case the red ampl, this also may cause the retrace lines and tv shutdown.i hope this explanation helps you better understand what might be going on with your tv. In both cases technical analysis will be required and in some cases even the picture tube condition can be corrected with out having to resort to a picture tube replacement. i hope i answer the your inquiry to your liking and if so please let this site know by leaving some pos feedback.

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.

WEGA 36" : Screen is low contrast and green


Sorry to say, it sounds like a bad picture tube, But could be also the capacitor that filters the screen voltage on the crt drivers. In all my years though, your complaint has been the picture tube. Good Luck.
