My Macbook had display problem (used to work with external display) and sent it for repair. They seemed to have tried with a third party screen and done something, now it is not working on both internal and external displays.
Luckily I had anydesk installed beforehand, and still I can use anydesk to connect to the no-display mac. I checked the display preferences, and it shows 23" display instead of the 16" retina display.

Even connecting the external display does nothing. I suspect this has some link with the both internal and display not working. I have already gave up hope on internal display, but would like to get it working on external display.
Connecting to external display shows the initial mac startup image like this for halfway and then stops working on external monitor as well, however internally the mac starts-up and works whcih I can verify via anydesk access.

I have tried SMC reset, PRAM reset, safe mode, etc. In recovery mode, it works normally in external display until certain point and then gets stuck just like in startup screen.
Could there be any other configuration I can change to fix this issue till I have anydesk access? Could it be some issues on the software os side or hardware side? I would at least make it work in external display.

Switching to Integrate graphics error: (wondering if it could help with the problem)
