Hello, folks.
The TV in question just died on its own. When plugged in with the rear panel off I can hear momentary hissing from the PSU. The LED indicator is off. No response to the POWER button.
PSU:
The fuse is good.
Varistors are good.
No bulging capacitors, nothing out of the ordinary.
CN102
Pins 1,2,3 (Standby) = 5v
No other voltages are present anywhere on the board.
My guess the MB is dead. Is there a safe way to connect CN102 Pin 1(+5Vsb) to either CN102 Pin 11 (Remote ON/OFF) or CN102 Pin 12 (Backlight ON/OFF) to verify my diagnosis?
Thx!
