ALL 3 COLORS ARE SEPERATED AND CONVERGANCE DOES NOT FIX


We fixed this same problem as a dyi project. Check out www.tvrepairkits.com. The kit itself come with the proper chips, fuses, and very detailed instructions which includes pictures. They also have online help if you have questions. If you know how to solder and are a very careful person, this is something that you can fix yourself.

Pink and green colors seperated images rounded off


If colors are skewed and will not adjust in the customer menu---you have a CONVERGENCE circuit problem.

This model (KP-51WS500) uses two of the STK-392-560 convergence IC chips. I just got home from fixing a similar model with the same problem.

Parts cost on Ebay for the chips and such is going to be less than 30 dollars total. Shops are going to get 300 or more for this kind of repair---and some will not do it in your home---the repair takes about an hour--I have done hundreds of them here in people's homes.

If you have questions or need advice, reply to this posting and I will try to help.

52'' Projection TV SONY


this is a problem with the convergence chip. you can try to adjust the convergence in the menu settings of the t.v.
pin cushioning will correct the curves, convergence fixes color seperation.

write the number down before changing them, in case you make it worse.

TV picture curves


This is a convergence problem and is usually either bad connections at the convergence ICs or defective ICs. If you can solder, you can fix this yourself. Locate the convergence ICs (large black Ics attached to a heat sink and marked STKxxx). Resolder the pins first. If that fails to resolve the problem replace the ICs.

Keep us posted.

Arched picture at bottom seperating the green and red


Your tv has a convergance failure. the convergance ic's need to be replaced. Upgraded part # STK392-150 or STK392-160. Both ic's should be replaced to prevent future failure of other colors.
