Open the TV set and at the end of the CRT, there is a Circuit board (Video baord) where color adjustments are manually done there. OK, normally there are cracks or cold solders on the terminal of the components which can be the cause. You'll need a technician to do the re-soldering of the terminals. cheers.

Blue shadows appear to be behind white objects


TV shows large red spot in middle of tv when dark show are on, you can see it more.  Now blue spots on upper right side too.  Spend way to much on this tv to have these kinds of problems only after 3 yrs.

Why does my TV have a red shadow on all the people and words. i've only had it 4 1/2 yrs


It sounds like the red gun is off. Your tv uses three guns(red,green and blue) to make the picture. sometimes one of these guns shifts a little and the colors get messed up and there are shadows because the gun is still trying to make the image, it just doesnt line up. This is a pretty inexpensive problem that can be fixed by most any tv technician for a small fee. If your pretty confident in your electronics know how, google adjusting guns and your tv and that should yield something.

Picture has blue,green,and red phantom lines on the screen


Sounds like a convergence problem. Are you interested in fixing this yourself? If so you will need to know how to solder well and use a meter. I can assist you as much as you need through the process. If you post a picture of what the screen looks like we can know for sure what you have going on. If you call a repairman to fix it he will charge somewhere between $300-$500 to do the repair. Let me know if you need more help!

Maganvox TV with red-shadow to picture


Hi Emily,

Your TV has bad convergence amplifiers. They are large integrated circuits that are mounted on large metal heat sinks. They have a part number on them, but might be covered up by a bracket. The part number should start with STK. They are replaced as pairs. You will have to find someone with the skills necessary to replace them.

Best Regards,
