Hello there, the context here is about a week ago my sister gave me her surface pro 3 to keep so i was doing some college work on it when my nephew jumped onto me. After about an hour i noticed some flickering lines on the screen. It also sometimes turns completely black for less than a second too. I left it for a day and it hasn't stopped as shown in this video (it shows up best on steam for some reason) So I'm wondering if there's any sort of fix or if I'll just have to send it in for repairs. Thanks for reading.
