Re: Picture Problem , Sony Projection TV

Your TV most likely 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 Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

Sony kp-53s35 bowed picture on top and bottom

Good day, scotty1980;
Scotty, welcome to 2008. Hold onto your wallet, the has a convergence problem. Which means that the TV's convergence IC's are more than likely bad. The average cost to repair is about $450.00. Unless you are electronically friendly, I would call an authorized service dealer for repair.
Good luck, big IRISH. PS; Hope this was helpful.
