I meanwhile found, that there is firmware version 3.2 installed (Booting 
while hold patch 1 and 3 -> FW version is displayed in the lower part 

Just a simple idea: This JP8 has a very low serial number which 
indicates a 12Bit DAC (according to the service manual 2nd edition). Is 
this JP8 Version compatible with the Firmware Version 3.2, which is 
installed now?
