Dear Community, My mk3 started with the last knob (from left to right for searching sounds, etc) NOT selecting the SELECTED sound, etc but others instead like if it were loose. At the same time the left screen started changing quickly from one screen to another like if I was pressing other bottons. After a few days like that a line appeared in the left screen as shown in picture and now not turning on at all. Please help! This hardware is been always very well cared. Never dropped it or been using it a lot! I can say I always used only the power from the Mac. I’m in Costa Rica. Thank you so much!
