Hi
I have a LE32C350 LCD tv stuck in standby. The PSU is model number: BN44-00369B that i have the circuit diagram for. I have good power output from this board with 13v and 5v outputs all caps measure good esr.
Power supply diagram below.

The main board is model number:BN94-02670B that i don't have the circuit diagram for. Power rails come onto the main board and then blocked by a P channel mosfet that isn't being turned on (driven into saturation).
Any common faults with this unit?? as without a circuit diagram for the main board i'm struggling. Any help will be greatly recieved.
