While all selections are full, the sold out message displays digitally. When I open the door, ER-1, cj 1-10 is displayed. However, none of the columns are actually jammed. Sent logic card in for check, shop found no problem and cleared the codes($85). Wondering if the shop really benched the thing, or just ripped me off. Does this sound like a logic board problem, or something wrong with machine? I've checked all the menu options thinking of a possible conflict. This machine is beating me up. Any thoughts? Thanks.
As a follow-up for any others in a similar situation. Looking at the schematics, I found that the 5 amp fuse had blown. After replacing the fuse, all was well. A hint, the lamps also interface with this circuit, so if the lamps are dark, and the machine is displaying sold out, with column jams 1-10, be sure to check the fuses. Prayer didn't hurt either.
I am going to check that Vendo fuse first thing monday.

I was having the same problem. I have two fuses, one kept blowing, I traced the wiring to the lights, but I wasn't worried about the lights working at this point, so I kept looking for the source of the problem. After reading the above comment and finding out that that fuse didn't operate just the lights, I began searching for bad wiring. Found out it was the ballast to the lights that was blowing the fuse. I unplugged it, and was then able to clear all the phantom "column jams". Thanks!
