HELP! The keyboard of my EPS16+ is not calibrating anymore. When i boot it, is says. TUNING KEYBOARD - HANDS OFF and after a few seconds i get the message: KBD FAILED - TRY AGAIN? when i say YES, it returns the same error over and over again. When i say NO, my keyboard (the left side) is unusable. I opened my EPS16+ and cleaned it the best i could and it helped for a while and now it's f*cked up again. I know this has something to do with the pressure of aftertouch but i don't even use these features. Is there a way to get around this calibration error? I don't need pressure d*mned!
