Hi, i'm trying to repair my Lenovo IdeaPad3 (model: 15IML05 81WB). Basically the screen lags and flashes after i raise it or if i try to move it. I was told that the problem could be the screen or the cable connecting the screen to the motherboard but both of them work fine. I tried also to see whether the problem was the removable part of the RAM (4GB fixed in the botherboard and 4GB of removable RAM) but also in this case it works fine. What do you think might be the issue?
