Answer to "Why won't my tablet's screen respond to touch?"We have an Asus tablet that first had intermittent touchscreen problems such as non responsive areas on the screen and ghost touches. All the factory resets and software updates did not help at all. We bought and installed the new digitizer screen - no change. Cause: bad contact of the digitizer ribbon cables due to the loose latches. Advise that finally helped: cut a piece of film (like the film used to protect the screen) to the size of the digitizer cable and insert it on top of the ribbon cable into the same slot. The problem seems to be common across all manufacturers.
