Turrns on blinks 3x and turns off

I bought this LG TV off BestBuy about 2 years ago and this week I went to turn my TV on nothing turns on. The Red blinking light blinks 3 times before it what seems to be shuts down.


TV model in the device is wrong I could not find it on here so here is the model of the tv and what I have tried.


TV Model:

LG65UH5500-UA it’s a smart tv (not sure if that matters or not).


What I have tried:

Wiggling all the cables making sure they are all in.-no result

Removing all the cables and just tv plugged into the wall.- LG logo came on for a split second and turned back off, when I tried to turn it on again I was back to my same problem.


Removed the outlet off the wall and held the power button for 30 seconds then let the TV rest for about 6 hours- LG logo comes on and off but still goes back to the same problem.


Any hints or help would be appreciated thank you all for reading and any comments.

There are three possible reasons that would cause you to face this issue;

  • Power board is faulty and/or dead. This would require a replacement of the board
  • Main board is faulty and/or dead. This would also require a replacement of the board.
  • Backlight LED Strips are fault and/or dead. This would require a complete disassembly of the T.V. to expose the LED Strips in order to manually test each LED to ensure they are working.

The issue is that it could be either one of these three issues or it can be a series of them. I would recommend that you start with the power board then the main board ending with the backlight as the process involved to repair the backlight LED strips requires advanced technical knowledge and time.

Is it possible to test out the power and main boards before replacing them? I checked the prices for the replacement and it would be cheaper to just buy a brand new tv then to repair it from the cost of the parts

This would require another T.V. to test them,
