This TV has had a previous repair that has not worked.
Capacitor CP810, the bridge rectifier and the fuse were damaged and the mosfet and FAN7530 were replaced out of caution.
The new bridge rectifier is a RS450M and the mosfet a 8N60C.
I have 340V across the main capacitor CP815, which doesn't seem right ? and there are no voltages on connector CNM802. Testing voltages on UM801S there is 340v on the drain but 0v on VCC.
I've checked all of the diodes and mosfets but I'm clearly missing something obvious and hope someone can point me in the right direction.
