Kp-57ws500 sony projection tv convergence problem

Hi, I have a kp-57ws500 sony projection tv with a convergence problem. I know this because I have fixed another samsung tv with the same problem. The only thing is with the samsung I just replaced the whole board. I was wanting to just go ahead and try to replace the ic's myself. I have found directions on how to do it and I think I have a good shot at it. If not,what is the part number for the board? I can't find it online. The one bad thing about the whole situation is that I have no experience in soldering. Do you think I should just replace the board?

Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from www.TvRepairKits.com and do the repair yourself. Its a fairly easy DIY fix.

look for the board that has heavy heat sinks on them the ic will be stk392-XXX

Tv turns on but has a shadow around evrything


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
