My Oled tv doesn´t turn on after bezel was bent,

Hi

I recently acquired an LG oled TV (OLED55CX6LA) for free. The tv won´t turn on after

the bezel around the screen was dented (very small dent!).

The TV only goes to standby and when I try to turn it on the relay clicks once and it goes back to standby. I tried disconnecting the four panel connectors to the T-con board one by one to no effect. I then disconnected the lower cable connecting the main board to the t-con board and then turned on the tv. Still no picture but the relay didn´t click when the cable was disconnected.

Any ideas on what the issue might be?
