Did you check the resistors and the 4 fusible resistors right next to the ICs? Often one or two will be open and need replacing with the ICs

Double picture out of alignment


Hi:
Your problem is its time to replace the convergence IC's. Replace both of them as if one has failed depending on which color is out of convergence the other is not far behind. They are the two large black IC's mounted on a large metal heatsink, also while replaceing them check the small yellow or green micro fuses underneath the IC's to make sure none of them have opened from the result of the IC failing.

Sony 57 inch


Hello

there is two STK packs in your TV, this is what controls your convergence,it should be two big IC on big heatsink and number should start with STK- ______,just replace these STK packs and you can order these from matelectronics.com. Parts should be somewhere around $30 and also make sure that resistors around stk packs don't look like they been hot if they look like they been hot just replace them too, and your TV will be working fine.

Thankyou
