1 LG OLED G2 55 screen not turning on while standby light on
One day my screen just stopped turning on. I've done all the soft reset/drain caps procedures to no avail. Model# OLED55G2PUA
With everything connected, when I plug in the TV, the standby light comes on, briefly turns off, and then returns solid (which I've read confirms main board is OK) The relay on power board does not click during this process.
If I disconnect the 12v power between power board and t-conn board OR disconnect the ribbon that travels between t-conn board and mainboard from P7601 location (pictured below), when I plug the TV in the standby light comes on, turns off (relay clicks at this point), and the standby light will pulse 3 times and remain permanently off.

I did the troubleshooting preformed from this ifixit post but regardless of which of the 4 quadrant t-conn ribbons were connected/disconnected the voltage on the board always showed 22v and 12v respectively and at no point can you see the optical light on main board come on.
@larrylupe what is the complete model number for your TV?
