Hello alltogether!

Recently got a Polaris. When playing harder on the keyboard it suddenly seemed to crash and rebootet some way and now no sound, response to midi and when pressing one oft the program-buttons in the right side, all LEDs go out in the leftt side oft the panel. After opening the unit  a part oft a screw Fell out, so it might have caused a short somewhere. Does anyone oft you have a suggestion what might have been damaged ?

Looking forward to your answers.

Best regards

Moe
