Hi. First time post. I've scoured the previous forums looking for info - there isn't much for my model
UN65MU8000FXZA
We had a power outage. Everything plugged into the Monster surge protector seems to be fine except my Samsung TV. It was dead when the power came back to the house.
Here's what I've looked at:
Unplugged main board from power supply - BACKLIGHTS COME ON.
Ordered new main board - still didn't work. Not sure if used MB was DOA
MAIN BOARD = BN94-12295K
PSB= BN44-00912 L65E8NR_MHS
There doesn't seem to be a pin for Standby like on other boards
The value on pin 16. power on/off seems high but what do I know.
Please help me diagnose - is the power supply board done?
Here are the values I tested for VOLTS. I didn't have the needle tips for multimeter so made my own but here are the values
WITH = with MB connected
WO = without MB connected
CNM803 WITH WO
1. GND 0 0
2. GND 0 0
3. GND 0 0
4. GND 0 0
5. VAMP 9 12.85

7. VAMP 9 12.85
8. OD_LEVL 0 3.2
9. VAMP 9 12.85
