Question about Sony KP-53XBR300 53" Rear Projection Television
If the flash focus will not fix it you have a problem in the convergence circuit(if way off adjusting with the remote will not help).
This model uses (kp53xbr300) two STK-392-020 convergence IC chips---they and any bad resistors around them will have to be located and replaced. You can buy both chips for less than 20 dollars on Ebay. If you can do this yourself you can save a lot of money---
If you cannot do it--shop around in your area--most shops try to charge 300-400 for this repair and if they say it has to "go to the shop" keep looking, as almost any good tech can do this repair in your home in about an hour---I have done hundreds of them and here charge 200-250 total for this kind of repair in the home.
Once the chips are replaced the set should not have this problem again for 5-8 years and these sets are much more stable and have less problems then the Plasma and LCD sets.
