Nexus 7 Not Booting; Backlight Turns on while Charging

Nexus 7 Not Booting; Backlight Turns on while Charging References A friend of mine has a Nexus 7 2012. Although it used to work, it now won\'t turn on. I would mark this off as a broken battery or screen if it were not for this one oddity: the backlight turns on while the device is charging. I am unable to reach the bootloader or recovery mode. He does not know what Android version it runs, so I can be of no help there. He also says that this happened after he let his Nexus turn off due to low battery. Is there any way I would be able to fix this issue (say jumpstart it and use USB debugging to fix it?), or is the device truly broken?
