No power. No LEDs.
Purchased power supply repair kit from SJ.. Same symptoms. No power, no LEDs.
Standby voltage is present = 3.3v (CN6152, Pin1). No other voltages.
Jumpered Pins 1 + 3, Standby voltage pulses from 3v => 0V => 3v, repeatedly.
Transistors and diodes seem to test OK. Not sure how to test MIP2H2(IC6201) or CXA3740M(IC6502), although both of these are new and installed with no issue.
Power supply board for reference. Thoughts?
