Need help with LG portable AC - compressor starts for couple of seconds and then turns off and won't turn on again unless you reset and wait or reconnect the capacitor wires.

-Replaced power relay and capacitor.

-Manually tried to start the compressor and it starts.

-Fan works on all speed

-compressor fan stops at the same time as compressor but did start manually to check on both of its speed and it works

-Did check the ohms on compressor three pins and they all add up to the same value like 2.9ohms and also like I mentioned it works when started manually through power relay

I am not an expert but have knowledge about HVAC working and also about electronic components on the logic board. But stuck here.

Can provide any photos if needed of the control board etc.

This is the exact AC I have and also below is a video repair of the exact AC but this was only for bad power relay but you can see the components on the board.

Thanks in advance
