Disconnect LVDS cable and try again, if no result try to start up with P-Only button on service remote.

Most problems I have read with these are shorts at the 24v side.

True, 24V could be the problem. There could be a s/c in the t-con but aso the panel.

I disconnected both the t-con and the panel but nothing changes, after 3 sec the relay returns open
