Mnm frozen(?!)

Hi.

So, my lovely little machine (SFX-60) is giving me quite a hard time at the moment. After doing a simple sequence while connected to Ableton, about 10 sec into the recording it just STOPPED. Ableton froze and I then had to force quit it. However, the mnm still isn’t working! I tried the different resets (factory and soft reset), I’ve left it to chill for a day, but it’s STILL not responding to any contact… All buttons are lit, and the display looks kinda weird, only two lines going vertically along the display.

Anyone who knows what to do?
