Holy crap! That was a ton of soldering. Found the bad cap and I have a working TV! Not too bad for a $150 Craigslist find! Thanks for the help.

or at least identify which cap was bad... :-) good work. I think another thread might find value in this work.

Sounds like another failed MLCC, they may have made good LCD glass panel but use bad caps on the tab bonding board.
They need to improve incoming inspection and handling of the MLCC.

I agree with you Budm. We are seeing a lot of Samsung UN65MU6500FXZA with just a power supply/led driver board and a main board only and finding a lot of shorted caps on the lower tab bonding board. If you see the tv turning on and off by itself with everything connected its rarely a main video board problem and with the cable disconnected from the power supply to the main the backlights work good with proper voltages on the led leads. I don't have the time to trace them down because we are too busy with the everyone staying at home. Change one cap out and another one will go soon so I just tell the customer to buy another tv and tell all my customers to avoid this model like the Covid19. Samsung quality is starting to go down hill big time.
