I have an HTC Thunderbolt with a LCD problem. There is no visible damage, but there is a part of the screen about half an inch wide that runs top to bottom where the touchscreen doesn't work. I can't type letters that appear in the area, and programs like art programs produce jusut weird lines in that area. Is this something that a glass/digitizer repair would fix? i don't want to shell out the $100ish unless i'm pretty sure
