Your TV most likely has a convergence failure. ( common problem )

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 are some photos of convergence problems.

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.

SOLUTION

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

SOURCE: Blue will not Converge

This is the typical convergence problem. There are two IC's that need to be replaced. They are soldered into the printed circuit board. If you have no soldering skills, and are in the US, you can take the model number and go to http://www.ptscorp.com, as they will rebuild or sell you a refurbished board . There is a phone number listed at the site if you need help getting the pricing. Good Luck

Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from www.TvRepairKits.com and do the repair yourself. Its a fairly easy DIY fix.

43H70 Blue Convergence out of line and will not line back up

If the blue colors will not line up, and the blue appears to sag inward from one or more sides, then you can bet that one of your convergence IC's has either cracked loose or burned out. The IC should be resoldered or replaced and the convergence realigned by someone experienced with projection TV convergence circuits.
