Hello, I accidentally broke the screeen on my surface, so I went to a local repair point to have a professional repair of my PC. All good but after a month the screen has started to have some red flash as you can see in the video. So I returned to the repair point and he tried to repair but he said that is not the display but is the graphic card broken, so I can't do nothing. Do you agree with him or is a problem of compatibility/ display broken?
I tried also to connect to a external screen via HDMI and there isn't any red flash
Thank you
