About a month ago I accidentally cracked the bezel on my MB Pro. I decided to put black electricians tape over the crack so that it wouldn't grow and to keep dust and irritants from possibly entering. At first it was mostly a cosmetic issue but after about a week or two thin vertical lines started to appear on the screen right above the crack. I've read online that the bezel is a relatively easy DIY repair, but I doubt that will get rid of the lines on the screen. Is this a problem I can fix on my own, and if not, does anybody have an idea of how much repair would cost me?
