LG 50PA550T Clicking when connecting power and does not start up.


The Tv got theese symptoms.

When Im connecting the Tv to power it says click with a paus of 5 seconds then it says click again. This repeats over and over again until disconnecting power.

Disconnecting the Y-board does NOT change the symptom.

Disconecting the X-board DOES, the Tv then stop clicking and just click once after connecting power.

The screen does not light up at all.

I need your help to find a solution.

@johanness first you want to let us see what you see. Take pictures of all of your boards and post those with your question. Use this guide for that. In the meantime you also want to check the voltages on your power lines. Most common failure however is the power board. It is possible that your IPM's on the Y and Z boards may have failed. They are located beneath the heatsinks on those boards.

the clicking you hear is most likely from the power relay on the board.
