It is probably your convergence chip.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.


If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem. 


Here are some of the most common symptoms. 
Screen looks 3D
One or more colors can't be adjusted when using the convergence menu. 
Screen is bowed in but stationary.

Solution:

You need to replace the convergence chips and convergence resistors. Check the site http://www.TvRepairKits.com . They have put together a kit for your exact model. The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc. Everything you need to fix it yourself. 

Hope this helps,

No picture on tv screen


try resoldering the vertical output IC. sounds like the cRTs are blanking due to the vertical. If that doesnt help you may need a new IC. While youre there look for signs of the CRt leaking as often it leaks right onto the vertical output section real close to the IC.

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,

MyTvGuy
