Red Convergence on 2001 Toshiba 50H71

[george]

Lost left/right convergence adjust on red gun. What are the STK
numbers and where do I locate them in the PCB? Want to replace both
while I'm at it. Also, source for a schematic so I know which
resistors to check would be helpful.

Thanks

If you do these units for a living, you won't need a service manual!
Two STK 392-110 convergence IC's will fix you up. Double check the
numbers...some may use a slightly different number. Buy good quality
parts...notcheapy ones, they will last a lot longer.
Hardest part is getting all the legs of the IC's to line up while
installing them. Check the pico fuses, there are about 10 throughout
the chassis. Also, make sure no low value resitors by the IC's are
open, or changed value. Check for bad connections in the arear also.
Good luck, Dani.
