Open Question

I have Samsung UN65NU8500FXZA Which is not working.

TV power light blinks 2 times and tv tries to kick in but turn off again. I open the back cover of tv and disconnected the main board to power supply and noticed led lights were lid and tv screen was on but was dark (no picture) but when i connected the main board back to power supply the TV power light blinks 2 times and tries to turn on and then goes off again and same cycles repeats. I put small piece of tape and covered few wires of main board flex cable installed B/W power supply and flex cable and then i observed that the TV started sound was on screen was lid but there was no picture. Not sure if the main board is bad or there is any other issue.

Hi My Samsung UN55F6300AFXZA WHO4 won't start but keep blinking red light 5 times and start blinking again with small interval.

1. open the back cover of the TV, disconnect the cable between the main board & the power supply.
2. Apply the AC power to the power module, if the back lights are not light up, change the LED strips (IF the back lights are bad, in some case, the power supply also been damaged), If the back lights are light up, please change the main board.
