Re: Samsung PN51F8500AFXZA, PSU BN44-00619A, Short QP802S, ICP801S testing/sourcing
It's a Harbor Freight voltmeter, and you are probably right R_J. I bet it isn't reading the right voltage either. Here's why:
After about 2hrs worth of testing the PS out of the TV with stable voltages I decided to put it back in to the TV and try it, mainly to apply a live load and get the board to operating temperature, trying to get it to fault again.
The TV has now been working properly since, far as I can tell. It's been on a total of 5hrs with the back off so I can check voltages, which for now are appropriate and stable. I guess I'll keep using it until it faults again so I can perform further testing.
I've scratched my head so much on this one I now have bald spots! As soon as it faults again I will re-test and report. I do not believe the rectifier diode is faulty.
