I’m just not sure what voltages I’m supposed to be getting on CNM 803 as they aren’t marked on the PS board.
The voltages and pin numbers for CNM803 are clearly marked on the BN44-00876A power supply board.
There is no 3.3 volt standby supplied by this power supply, only A13v The main board supplies all the other lower voltages.
With power removed, disconnect the two cables going to the panel, plug in tv and see if it will turn on (there will be no picture)
