I have a Panasonic 'Quintrix' (crt) 32" TV (approx 8 years old). Recently the picture has started to have either a pink or a green 'hue'and no matter how much I adjust the picture settings I cant get rid of it. Most of the time its pink but every so often everything is green....??!! Before I send for an engineer can anyone give me any pointers? I know its an old TV but we're planning to get it working properly before we replace it because we were hoping to give it to our elderly nieghbour who's TV is 21 years old Thanks
If the colour change is consistently there all the time, the CRT guns are probably losing their emission. If the problem is patchy colour which changes on "peak white", (high beam current) it could be the shadow mask behind the screen bending and causing misconvergence.
It may also be the degausing circuitry which is not working correctly. This can sometimes be caused by not using the switch on the TV and instead switching of from the wall. Many user manuals frown on this practice.
