regardless of battery life. This is happening now, usb just has to be plugged into the unit, not actual power. Anyone else experience this?
Try a backup then factory reset?
Wont power on at all now
i had the same issue last year but the USB transfer wasn’t working also, apparently the main ‘dsp pcb’ was in cause
How did you resolve?
It happened to me twice since 2015, i did send it back to TE for a repair under warranty, last time (may 2017) it took 6 months. I hope i’ve just been out of luck, but since i’m careful about what i connect the OP-1 to.
