Samsung LED Smart TV Red Light Blinks 5 Times UN60H6350AF

I have an UN60H6350AF Smart TV that when pressing the power button the red light blinks 5 times and goes out.

I have opened up the TV and when I unplug the main board from the power supply I see the LED light come on. Makes me believe the power board is fine. How do I determine if I need to replace or fix the Main Board or T-Con Board?

Thanks in advanced.

it’s a bit like guessing. I would check to see if you have power on the BL-En on your connector. That is the power to enable the backlight by the power board. If you have that then it is most likely the t-con board. Check the fuse on the t-con board for continuity and voltage. You should get ~12V on that.

When I unplugged the main board from the power board, the screen lights up and I can see the light coming through the screw holes as well. With that I assumed it's either Main Board or T-Con, but wasn't sure how to determine which one it was. I'll find and check the t-con boards fuse and voltage and see if that reveals anything. Thanks.

hey guys I know this is an old post and this is possibly wasting my time, but I have this same exact TV that won't turn on has a standby light and when you try to turn it on nothing happens except the light blinks once and then goes back to full red. Any way to figure out which board I need to replace, upon visual inspection there is no bulging capacitors or burnt parts of the board this is the same for the mainboard the powerboard and the t-con board. I have a meter but I have no clue what to check voltage wires to see which board might be bad, any help is appreciated
