Sounds like you might have had a hardware failure. 2 things you can try.
1. Try a factory reset. maybe something isn't working and a factory reset is needed. Push and hold reset while its powered on until the lights change

The problem with combo devices is that the ISP controls the firmware so you're limited in what you can do to try to fix issues.
