When stuck on the logo , you cannot go to the service menu to reset the settings.
Option two:
1. Find the firmware for the board and reinstall it.
2. Turn on the TV, let it boot for 10 minutes, try to go into the engineering menu and reset the settings.

I can’t tell you the correct option, the system is the same but the TV is different

Good luck
