Pioneer XDJ-RX2 failed function

Dear all,

after I did firmware upgrade (since July 2019 1,37 versNr.)now I recognized, that after connecting USB and loaded the track on deck1 I can not play the track in VINYL mode. After I switch on NORMAL mode, the player is working very well, but as soon as I push the VINYL button again, the player stopped the music...Interesting is, that on deck 2 I don't have this problem....

Can somebody please help me what is the problem, what a hell is going on with my player?

Thank you in advance, and cheers

Gabor
