Cleaning not solution, i have 2 player, same problem randomly. If not used vinyl mode, rarer the problem. (Not vinyl mode: all paused point added new cue point. → NOT TOUCH PROBLEM (touch not sensing in normal (not vinyl) mode, software error!)
Flashed again latest firmware, not solution.
The problem very random. After 20 min or after 4-6 hour… My last 3-4 live mix (4-5h long) worked without problem, earlyer home mixing (1-2h) error again.
