Hi, I have done a very stupid thing! I put my iBook down where I thought it was dry but it turned out to not be. This was some time ago. Initially the screen appeared to have bubbles behind it,but all else seemed fine.Having left the whole thing to dry out over several weeks the bubbles have gone but the bottom 1/3 of the screen has the dreaded vertical lines. Should I assume that I need a replacement LCD or could the situation be more serious. Any suggestions would be great. Cheers.
