I'm in a touchscreen problem myself, but it's kinda different. Through the constant abuse of Osu Tatakae Ouedan 1+2 and Elite Beat Agent on insane mode, my touch screen's is scratched to fuck. I even have issues when I try to spin the wheel in the game it seems like there is stylus to screen problems (like there is something broken behind the screen even though the screen is fine). Cut a long story short... is there any cheap affordable way of getting the touchscreen replaced or replacing it yourself.
