Im afraid the answer I have may not be what you were hoping to hear but it sounds like you will need a screen replacement. Unfortunately there are no guides for this repair on this site that I could find but a google search found a couple of youtube videos doing repairs to the stealth. You can buy a new screen on ebay for a few hundred dollars and tackle it yourself or pay Razer $560 to do it. If it isnt very noticeable and the touch screen still works I would personally hold off on the replacement. If you do it yourself be sure to make a guide to post here to help others in the future that run into this problem.
