On my Samsung UN65JS8500FX tv,, the red light is blinking and i hear clicks from the relay but the tv never turns on. I took the One Connect box out because I damaged the connecting cable while unmounting the tv and then it started again. After sometime, it is back to the same problem. How to check if power supply board, main board or T-Con is faulty ? I have a multimeter too but dont know where to check the voltages on these respective boards. Thanks.
@mnm1982 you can measure the output from your power board to the backlight LED’s etc. Since your TV does not come on but clicks you will have to check the power board voltages.Use your multimeter and check the voltage on the connectors according to the values printed on the board. Since you also have no backlight when your disconnect the main board from the power board it stands to reason that you have a bad power supply. Second suspect is the main board
