It's most likely a failure of the convergence amp and some other power supply problem in the convergence circuit by the sounds of it... Your unit takes an STK730-130 and some 750k 1/4w resistors for the yoke return. I would bet two or more of them are out of value, at least R19702 and R19703... There are also two diodes Cr19710 and Cr19709. P/N# 164590 which commonly open under a load and are recommended to replace anytime the convergence amp is replaced. Also check Q19700 (Bc457) which crosses nicely to an NTE123a...
Not real expensive in a reputable shop - just a pain this time of the year.. I would recommend getting it repaired, it's worth it..

You need to take your tv in and have the picture deflector re-aligned.  This doesn't cost much, My dad had to do that to his a few months ago and it cost 30 bucks.

Your convergence chips and convergence resistors are going bad. When they fail the screen colors will look distorted/3d looking.  Another symptom is one or more colors can't be converged using the convergence menu. You can purchase the parts over the internet. Just make sure you get Sanyo brand convergence chips and the correct flame proof resistors. You can also check the site They are working on a complete kit for this model.

Can you post a picture of what the video is doing? It shounds like a pincushion problem, but it may be convergence amp as well. A picture could clarify it for me so I would know which direction to assist you in.

Try unplugging your set, If you didnt save the changes this should reset it back to default settings. If that desnt work, you will need to go bak into the service manual and adjust the horizontal size. Just write down anything you change so you can revert back if you have too.
