My wife’s RCA tablet had been dropped and would not “turn on”. I placed it on a different charger to make sure the charger wasn’t defective and while charging, I heard a chime from the tablet so I then I felt it had to be something with the display. Upon opening the unit, I found that the ribbon cable that connects the primary board to the display had been pulled from its socket. The cable was secured with a piece of tape on the battery and when dropped, the weight of the battery pulled the ribbon cable from its socket. Reinserted cable and all is well.
