hi
I'm working on a RCA projection TV, chassis # PTK 195Y. model # P52960
i'm not able to control or adjust horiz. convergance, i've repl. ic U19500 eeprom
ic u19501, (503,504) in case. it is on that board for sure. i've put somewhat diff. pcb and it is working, however not complitly, but i can control horiz.did
anyone ran accross somthing like that??
i'm going nuts over that thing, PTS wants too much money for repair.thank
thank you
Replace the main convergence driver IC's ( the STK IC's) and that should after several adjustments correct your problem.
Yes my friend.. Check the IC u8201 U 8202 as well as U8203 along with the driver ICs u7001,2 and 34. Also have gad alot of troubles with Q7001, thru- 7003.
