Question about Zenith C27A24T 27" TV
I have a Zenith A27A11D TV and recently the reds (anything red) has a firey glow to the point where the TV is not even nice to look at. The glow surrounds the reds and obliterates everything else. I have toned down the color manually a bit, but naturally now everthing is washed out. Any suggestions as to what this could be and if it's something an everyday joe like me could attempt to fix? What part would I need to buy and where should I look for it? Thanks, Todd
If its a projection style 3 guns.Its worth a try remove the cover and access the focus box and adjust the dials (2) marked R.Only do this if you feel confident and switched on the convergence mode.

Todd, The fault could be in the red video amplifier circuit, and would require either a service sheet with voltages to measure, or an oscilloscope to observe waveforms and levels. It may just be faulty, noisy preset potentiometers on the circuit board, used to adjust various parameters of the colour system. If you are confident then go ahead and check these circuits. Another cause could be a fault in the CRT (cathode ray tube), or the magnets used for alignment. These require skilled knowkedge of what they do and one may have shifted.
