After replacing the kit from Tritronics Inc. supplied by Kevin Harris:
(9-
(1978-KIT $38.98 repair kit for 9-1978 module)
Includes: FX3403 | C3460 | C3406 | C3478 | QX3201 | QX3200 | QX3402 |
FLYBACK | CRX3412 | CR3215,CR3217
The set turned on but picture would go bright and dark and the convergence
looked like it was unplugged from the 9-1690 board. I found CR3204, CR3206,
RX3206, R3252 and the final culprit RX3210 the 1 ohm of pin 10 of the
flyback that supplies the 16 volt source for the 9-1690.
Thanks to all that helped on this dog.
