Strix G614 screen turns off on boot (after Rog logo). Sometimes not turns on at all

Hi, everyone. 
Yesterday at the evening was using my Strig G16 (g614) for projecting screen on TV. After some time disconnected HDMI cable I've founded out that screen not switched to main (laptop screen). Since that time laptop's screen behaves strange: sometimes on restart ROG logo appears with loading circle rotating and turns off (not blank as LED turns off as well) and Windows Hello sounds.

Strange that Windows recovery screen (with boot options) not always triggers screen to turn on but once in 5-10 restarts it do and then screen may stay turned on as long as I let it. So I suspect the screen and wiring is ok.  
What I have done:
1) Reset device holding down power button for 60 sec - doesn't work;
2) Re-install Intel drivers with DDU - doesn't work;
3) Tested on external monitor with HDMI - it works (currently typing using laptop + external monitor);
Can't even get to BIOS as screen turns on in BIOS once in 20 tries.

Based on your description, since BIOS operates independently of system or driver compatibility, if the issue also occurs in BIOS, we recommend taking the laptop to a local service center for further hardware diagnostics to identify the problem. Thank you.

Thank you in advance for your patience and understanding 🙂

Managed screen to turn on enforcing MUX to dGPU. Screen turns on once OS ready but UEFI, Recovery menu and Safe Mode still not triggers screen to turn on.

Any ideas ?

If you can access the system, have you tried using Cloud Recovery to reinstall the system and using MyASUS to install ASUS-verified drivers to test if the issue is caused by a system abnormality? Thank you.
