Eken GC10X (Allwinner A20) tablet won't boot but charges

[warnockm]

I have an Eken GC10X tablet that runs the Allwinner A20 processor. This tablet has been giving me problems recently where it won't turn on, or when its on, it won't turn the screen on. It used to take 5 times in which i held down the power button to turn on (or the screen saver to turn off). This would often be over the course of an hour. now i can't seem to ever get the thing to turn on. When it does work i have to turn the screen saver off so the display is on all the time (and plugged in to the charger). The thing isn't completely non-responsive. When its off and i plug it into the charger, the battery icon flashes and shows how full the battery is. When i unplug it the battery icon flashes again and turns off. I also "burnt" an SD card w/ the latest firmware from the Eken website and flashed it. It seems to have taken the firmware and ended the upgrade with "Card OK", but still nothing. I used to be able to get it to show up as a device in windows when i plugged in the USB cable, but it doesn't seem to be detecting it now. It just charges when plugged in. I'm kind of running out of ideas. Does anyone have any suggestions?
