My Dixie Narco model 3561 soda machine has problems with the display (shown in the video link below):
When I plug in the power, the machine starts up and immediately flashes these random characters on the display. Afterwards, the display goes blank.
The machine itself still accepts money, dispenses sodas and gives out change. Only the display is blank. I’ve already replaced the display board and harness, but the error still persists.
I was wondering, if this problem might be caused by a bad control board? Or something wrong with the power plugs?.
Also, I recently had a HVAC repairman replaced the refrigeration unit in my soda machine. Maybe he tripped something in the machine when he was installing the new compressor. I already looked over some of the wire connections, everything seems to be in order. So I'm not really sure where the problem is...
Thanks for the help.
