    The auto convergence selection does not come up for me to do the convergence and it seems like that is what the problem is.

    I have a Rear Projection Sony KP-48S70, and the convergence is off. Automatic convergence tool in Menu will not autofocus/autoalign it, and it appears as a red double picture approximately 2.5 inches off horizontally to the right. Is this something I can adjust manually, or do I need to replace this Convergence ICs you spoke of?

  • Anonymous Oct 06, 2008

    I, too have a Sony rear projection (Model# KP-46WT510, July 2003) that the red convergence is off to the right (happened today, just flickered and the red went to the right) When I try to realign the red it will only move up and down and not left or right. need manual and parts list.

    If you have the ORIGINAL remote, you can access the built-in diagnostic computer ( in SONY models ). Download the diagnostic manual from SONY, and it will tell you how to use the remote manually to adjust ANY of the IC units, and much more! It is not easy, but it can be done, and the manual covers MANY settings.But you MUST have the ORIGINAL FACTORY REMOTE, universal remotes WILL NOT WORK. Good luck, hope this helps.

This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually $200-$400 Be sure to vote/rate me if this helped Thanks!

Your TV may have 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.

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.
