Toshiba 50" Convergance

Must replaced the 2 convergence ICS and some or all it resistors.Must know how to solders?Buy a convergence kit at Tv repair World,Tvrepairkit.com to repair it ur self.The shop will cost u $300 for parts and labors.

Have you tried to adjust in the customer menu or in the TECH menu? I can tell you how to get into the tech menu--if it will not adjust there you have a convergence circuit problem and I can tell you what is needed to repair the set.

You need to change convergence amplifiers. Should be no problem for a professional

You may have bad IC chips.

Your convergence IC's are bad and maybe a few of the supply resistors. Not an expensive repair but definantly something you would want a technician to do for you. Hope this helps.

When this happens it means the convergance Ic's have failed ( STK392-110's) they will need replacing then the cross hairs will move again

Blue convergence IC is bad, but change both as red wont be far behind they are cheap about 10.00 ea at the following link.

I would take a look at the entire circuit board the STK chips are sitting on... I have the same problem with a sony KP-57wv700 and it turned out to be the high voltage controller for the crts got fried... part # BA9759F and it can not be replaced as the entire circuitry around it got toasted also... I just ordered entire circuit board. mine was the D board in this case...

BTW, did you check or replace the pico fuses? 3 orange ones on each STK circuitry. Check their resistance with an ohm gage should show continuity. My case they were 3.15 A each...

You are going to need a full convergance alignment to rectify this issue.
