Why is my OP-1 turning off intermittently?

My OP-1 has been intermittently powering off, often times immediately upon powering on. Sometimes it also has a lack of response from the power slider, like I’ll have to go back and forth once or twice and then it responds.

This has been going on for a good few months, and it definitely seems to have gotten worse over the last few weeks.

I’m pretty anxious about using it on gigs, and overall it’s definitely a drag. Haven’t found this same problem, and it seems that Teenage Engineering doesn’t actually have a dedicated tech support phone number or email address???

If anyone could help it’d be SUPER appreciated.

Thanks,

Jaron
