You can try to adjust in service mode but it sounds like you did not do this repair correctly. I would suggest getting instructions from sites such as www.TvRepairKits.com
Your TV has whats known as a convergence failure which is common. You will need to find and replace the convergence parts to fix it. You can get the parts and step by step instructions from sites such as www.TvRepairKits.com
Try using the Flash Focus to/or manually try to dial in the convergence. If you are unable to focus the TV using its convergence adjustment it's time to call the TV repair guy. Figure on between $250.00 and $400.00 USD.
it sounds like a convergence problem; in the customer menu there is an option to adjust it with the Sony remote---if either blue or red will not adjust in some direction---you have a bad IC---this set uses two STK-392-560 IC chips for convergence---both would need to be replaced and the set adjusted again. If this has been helpful give me a vote here---if you need more direct assistance--------- [email protected]
The convergence IC chips are available on Ebay from Surburban Electronics for less then 14 dollars for the pair.(plus shipping)
Do you have any speakers or magnets next to the tv? If so, that is not good. It may be a convergance issue. Check to see if you have any adjustments on the back of your tv to adjust picture. If not, if may be a faulty capacitor that needs to be replaced
Hi, Let me know do you have related service manual of Sony KP-57WS500 to guide you further? Without service manual it would be difficult for you to understand our directions like what to check and where to go in TV etc.

no experience in soldering i would send the board into ptscorp.com and have them repair it.
Best to get a tech to verify problem--you may
need a convergence circuit repair==change the
STK IC's and then check convergence.Please
describe symptom as you see it,if you want more
assistance.
