Your symptoms sounds like a damaged convergence IC’s.

There are two and sometimes three very large IC’s that control the convergence in a big screen set. They are secured to a very large aluminum heat sink.

Most of the time you can just correct the convergence through the television menu. All that needs to be done is line up the blue and red to the green. If the colors do not move then there may be faulty components in the convergence circuit.

You may want to consult a Television Repair Technician, or repair this yourself. If you want to tackle this yourself, let me know, I can give you some direction for the repair

I hope this information allows you to resolve this issue.

Double Image Red and Green


Here are some of the most common symptoms and example photos of a convergence problem

  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.

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.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick email and they will put one together for you. Their kits includes photo instruction guides, original Sanyo STK chips, convergence resistors, pico fuses, etc.

Color off


Lol some people would pay good money for a doubling tv. Me myself I can think of all those beautiful women and those extra features........... Sorry first thing is to call out a technician because it sounds like the de-gaussing mechanism of the tv has gone haywire or that there is a fault with the screen itself. Either way its not one that can be fixed without technical knowledge. Good luck.
