My nook will not power on
I've plugged in my nook to charge and the green light is lit on the charging cable indicating a full charge but it will not power on
The screen may be the problem. Either the screen is not plugged in properly, or that the ribbon cable is not working as it should. Either way, the lcd screen is not recieving video data as it is supposed to. Try asking professionals in your area to help you.
The best solution might be to replace the screen or try plugging it back in correctly. A professional may be able to help you better than I can. Good luck getting it fixed!
