Did you check or change any of the resistors - Check in the area near the STK IC's for burnt resistors.

Bad IC is my guess...

On anotehr note convergence is a very common failure on Projection TV sets.
  • 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.

You can see some example photos and find a solution here...

Convergence Issues...


Yes the Ics are easially replaced if you can solder. You will need two STK392-560 Convergence ICs and possibly the 12 4.7 ohm 1/2 watt resistors as Sony sets will usually weaken the 4.7 ohm. You can get the replacement ICs ad resistors at the following link and they provide free instalation instructions with picture as well as free online tech support in case you need additional help. Here is the link.
