I BOUGHT TWO 20 INCH TV'S IN THE LAST YEAR. NOW BOTH OF THEM SHOW GREEN IN THE UPPER LEFT HAND AND IN THE LOWER RIGHT HAND. WHY ?
This is typically referred to as a color purity problem and can be caused by two main things. The first cause can be stray magnetic fields which can 'magnetize' the TV screen either by something magnetic begint oo close to the screen or having turned the direction of the TV while it is turned on. If this is a purity issue caused by magnetic fields, it can usually be cirrected by powering off the TV for about 1/2 hour and turning it back on. All tube TVs have build in 'degaussing' circuits to cure just this issue.
If this doesn't fix it the other cause is a shifted shadow mask inside the picture tube itself and cannot be corrected.
