The first thing you need to check is the power of the battery. A dead battery will prevent the device from turning on. Also, the battery may need to be replaced because it is no longer able to charge. The LCD display may be broken or the back-light may not be functioning and this will hinder the device from turning on. Please see the troubleshooting page for more information.
