My sweet neighbor lady asked me if I could fix her tablet. It's a Pandigital Black 7'. I tinker with electronics as a hobby. I found the DC internal jack solder joint had broken. I was able to repair the jack and the tablet is now charged to 100%. The tablet will not boot. It splashes a screen so fast you cant read it and repeats this in a loop about every 15 seconds. I used my camcorder to do a screen capture. Here is link http://ffury.com/pan.jpg How do I fix this??? I am new to tablet repair.
