Indigo not working, please help!!

[Phase 4]

Ok, so yesterday I was using my Indigo fine, no problems what so ever. Then later that day the whole thing just stopped working, made a sound for a millisecond and then nothing. so I pressed the "panic" incase the voice count was too high, nothing. Tried turning it off, unplugged everything for 10 minutes and put just the audio out back in and still nothing.

LFO lights just freeze and switching through presets and banks is REALLY lagged, from the time I press the button to change the preset to the time it actually does change is about a second.

It also made some kind of sweep down noise when I turned it off once and today, after i did a reset (LFO Shape, don't know if thats the only way) turned on and then the screen went black.

It wont even send MIDI.

Any help is much appreciated

Thanks,
Phase 4
