I have several old cellphones that stopped accepting any touch input.... there has been no water damage and have not been dropped since they did work. they just sat for a while.
first I wonder as this is called capacitive does that mean maybe a capacitor is responsible and it may have discharged over time, if this is the case is there a way to recharge it?
second is there any way to repair something like this cheaply.
third is this normal that touch screens simply go bad from not being used?
