Had same problem with my sons Rca tablet...Nothing worked that I read so this is what I did.... Unplug charger, Take the screws out of casing and carefully pop casing off....There will b a small plug connecting battery to the mother board.....Disconnect the battery and hold down reset button for 5 seconds to drain power...After that plug it back in, put casing back on and plug it charger....takes about 10 minutes to do....Should boot right up!
