Hi,
I have got a 55 inch Samsung curved tv, it doesn't power on. There is no backlight, audio or video. I could see backlight on if mainboard is disconnected from smps board. I suspect the main board is culprit. Below are the readings I get on board -
Stand by voltage 13V
PS ON 4.5V
BLU ON 3V
OD ON/OFF 3.6V
ANA DIM 3.3V
OD Level 3.6V
Also the voltage on main caps is jumping from 391V to 168V continuously.
