Well, which ribbon cable did you clean? There is a ribbon cable for the
LCD itself, which should be 15+ conductors and there should be one for the
touchscreen, usually 4 to 6 conductors.

The touchscreen is what takes your inputs, so the cable that connects the
touchscreen to the board is what you want to "fix".
