It is permanently 'stuck' in either the '1' or 'zero' setting and The problem is that one of the logic gates inside that particular chip I'm talking about about has a burned out gate. Offhand, I don't remember the name of the chip or whether or not it has 6 or 8 legs on it. There is a small chip located on the left-hand side of the floor-located motherboard. I found out why because I had this VERY problem once. Sometimes using the Clear chip will erased the 'stuck' logic data signals, other times it will not. When the DBV's came in, IGT moved the door optics to a higher location.this is my theory and I'm sticking with it! LOLīut yeah, you're dead on knagl - it's doesn't really matter where they are as long as they're aligned to face each other when the cabinet door is closed. The reason for the other door optic mounting locations are unknown but exist on the older S+'s that used the left-wall MPU location before interior DBV's existed on these models. I have a few S+'s that have the other door optic mounting locations.Īs far as I know, there were two different locations. What else can I check? Have I missed something or am I looking at a board replacement? I've got so far as to bypass the door optics (jumper wire between red wire and black/purple - still no change. I was able to get it straightened out and reseated the board. Started looking for any obvious disconnected wires, etc and found a bent pin on the main board connector. Found that the glass covering the emitter was broken, so replaced that - still no change. Close the door, turn the key and nothing.īased on what I've read here I suspected the door optics. Completed the procedure, started the machine back up, got the code 61, held the test button down, get the 'boing' and code changes to 61-1. Decided to clear the machine again and start fresh. Reinstalled the hopper, code 3300 wouldn't resolve. Rotating the disc by hand the coins now ride and eject properly. Ordered a replacement and installed it with no issue. Traced the problem to a bad knife as the coins were slipping under it. Hit my first pay and found that the coins would not dispense resulting in a 3300 code. Replaced the battery and cleared the unit successfully. Right now I am stuck at the 61-1 error and can't clear it.Īpparently the machine has sat for quite awhile. I recently picked up my first machine and have been working through various issues.
