Sanyo DS19630 chassis 19630-00 mfd-1996 Original problem relay clicks on then off. found HOT (D1685) shorted. Replaced with a new (D1685) that says Sanyo on it even though I didn't order OEM. Fired with variac at 100v AC, B+ 80vdc and relay still clicked on then off. HOT ok with variac. Removed regulator (STR30135) which seems to check ok, B+ went to 139vdc relay still on then off. Turned variac down to 85v AC, B+ went down to 115vdc relay still on then off. Sounds to simple, what am I overlooking...???
I Replaced following even if checked good R601 (3.3 Ohms 5 W) (chk'd ok) R607 (5.6 Ohms 2 W) (was opened) R411(2.7 Ohms 2 W) (was opened) C606 (330uf / 200v) (chk'd ok) REG-STR30135 (chk'd ok) HOT-Q402-(ECG2331) (shorted) Now same thing with Q402-(HOT) getting hot & R601 very hot & starts smoking. Also need value of R621 (sandbox 5 or 7watt) #'s are burnt off and boards blackened in that area from running warm for apparently some length of time. Any other help appreciated. No Print.
