Did you know that there are 2 main parts to a touchscreen? (there are more but these are the main parts) There's the LCD and the Digitizer! The LCD is obviously the display but what you touch isn't actually the display it's a sheet of semi-conductive glass or plastic with a small current running through it. So that means that with touchscreen one or two things can happen: The Digitizer goes bad and the screen doesn't respond to touch, or The Screen goes bad.. it responds to touch, but you can't see anything to know what you are pointing to. On most touchscreens we can fix both. Touchscreens are very expensive but that's only if you have to repair both parts, but now you know that there are options. Got a problem with a touchscreen.
