I found two issues worth sharing.
1. Removing that plastic film "screen protector" cured one. I can only guess some nit was under the screen protector and tapping the screen.
2. There was another one which, since it was doomed we dissected. After we took it apart, it seemed a little dusty in the glass. We carefully cleaned the lcd and put the unit together and it lived on for awhile. Not for the feint but if it's dead how could you bust it?
We bought a Tungsten E for our granddaughter last year. She loved it, but now it won't turn off if it's charged by the house charger. Once it dies off & it's plugged into the computer then it will only stay on for a few seconds. The buttons won't work and she can't get anything on the screen to work. It has had both hard and soft resets and the calendar reminders were cleared, since I had seen that could cause the problem of not turning off. Any help before we shell out money for a new one would be appreciated.
