My acer aspire3 laptop screen was flickering and glitching, i'd hit it and it'd go to normal then suddenly it glitched again now when i turn it on i dont even see my cursor or the acer logo.On being turned on it looks normal minus the logo not showing and it having a line in the middle on touching the screen the left side turns white with horizonal or vertical lines It also has to be plugged in all the time otherwise it shuts down. What needs to be repaired/replaced?
