I have a PSU P/N BN44-00514A from a Samsung PN60E7000 that has no standby voltage.
Wondering if someone could help me troubleshoot this PSU as there are no replacements available so this is all that I have to work with.
I've tested QP802 QP804 as well as QS802 QS804 all seem to test good if I'm testing them correctly. DMM on diode mode, black lead to drain, red lead to source, touch red lead to gate, and then red lead to source again. Is this the correct way to check N channel MOSFET?
DP802 tests good.
All diodes test good.
Both fuses test good.
CP801 CP802 CP803 all show 160VDC
