Slot machines were not designed for use outside of a casino, so at times they are not particularly "user friendly". On occasion, your machine will show a number.

igt slot machine code 21

I was able to clear the error 21 by desoldering the battery for about 15 minutes. We service and repair all types of slot machines. Jay, I was thinking an error 12 is for a low battery, and 21 is for a coin-in error? If the comparator is not putting out the A pulse you will get a 21 error. Also, if the coin comparitor is missing from the machine I'd order one and get it installed. Could the problem be somewhere else? If the comparator is not installed and you drop a coin through the optic board you can also get a 21 error. When I switch the machine on, the displays show the number of credits that had been inserted with the button before I inserted the coin for a couple of seconds and then the 21 error is shown. If the battery is low - the coins will just drop through. Welcome, Guest. I would appreciate any suggestion. Here comes the problem: After playing a while I said "why don't I insert a coin through the optic board" I had no comparator installed , so the error code 21 was shown. You might open the door and turn the reset key. Quote from: Badbaud on May 24, , PM. Is the coin comparitor you tried using a CCD? The coin optic board is connected to the mpu board. I even read that the number 21 should disappear for a while after closing the door but in this case, it's always on no matter what I do. Sometimes it is hard to know ahead of time if something will fix a problem, you have to try it to find out. You are probably referring to your " mpu " board the large circuit board with the battery. I also realised that I have no U18 chip on my motherboard, is it a critical component? If you've benefited from this website or been helped by the friendly NLG folks that volunteer their time please make a donation of any amount to help keep the website running. After trying some other things I think the problem might been somewhere else. Unfortunately, I don't have a spare optic board. If you find this site helpful, please consider making a small donation to help defray the cost of hosting and bandwidth. I have tried with a coin comparitor after the error was shown and it keeps doing the same thing. I read that the error should be erased by opening and closing the door, but this is not the case. Welcome to NLG! Don't worry about it, I don't think any damage was done. Quote from: fedegiova on June 04, , AM. Congratulations on your success with self-made parts, are you doing that because you can't obtain the usual parts for the machine?{/INSERTKEYS}{/PARAGRAPH} But again nothing hapens when I close the door. Also, is this one of the prior discussion threads you've seen about error 21? Please do not PM me for support or "how to" requests -- please post your request in the forum so that everyone may assist you and everyone can benefit from the answer to your question! But my question is: why did it work the first time? The reels don't even turn as they used to when I turned t on before the problem. I will be seeing a doctor for my dyslexia sorry for taking the thread in the wrong direction. Just to make sure, are you turning off the machine's power when you disconnect and reconnect parts? Your NLG Staff. That usually will clear that 21 error. After that the winner paid showed the error code 61, I pressed the test button for a couple of seconds and the machine started its booting routine. I checked the door optics with the self test and it works OK. It even started the rebooting routine every time I closed the door. Let them that don't want any, have memories of not getting any. In one occasion, I connected the board I built incorrectly and one of the opto couplers blew up. Archives of old posts can be found at Hi there everyone! Logged Let them that don't want any, have memories of not getting any. A couple of days ago I tried to give it a go and try to see if the machine was working properly. Logged If you've benefited from this website or been helped by the friendly NLG folks that volunteer their time please make a donation of any amount to help keep the website running. Were you able to play because you inserted money into the bill validator? If you need something, call or send me a pm. I do have some spare parts though. So I unplugged one reel and nos the error 49 is shown. I was using the switch on the optics board, the one you are mentioning. Do you have another one that you can use to help troubleshoot this one? Please login or register. Quote from: jay on May 24, , PM. I believe the kind you need is a CCD. Pull the MPU board and measure the voltage on the lithium battery it should be 3. If you can't afford to lose you can't afford to win. After powering it on, the error 12 came up so I changed the battery and the error went away. I've managed to cause another error to check if the machine was able to do something else rather than show the 21 message. The reel errors are the ones I have found need the clear chip. I tried pretty much everything, I unplugged the optic board and plugged it again, I checked the connectors, I disconnected and connected the mainboard a couple of times, I even took the battery out for a while to see if that could take me to the first time I turned the machine on, but nothing helped. I even tried swapping the optic sensors among them but the self test results are the same. It seems that the optic board is not working properly. Hello everyone! Or you could try replacing components on the mpu board that directly connect to the coin optic board. It's kinda strange since the self test number 13 works great. Since your machine does not have a coin comparitor did you install the bypass connector as mentioned earlier in this discussion? It says that you need to have a coin comparitor installed, or a bypass plug on the coin comparitor cable. I also realised that I have no U18 chip on my motherboard , is it a critical component? This is the only machine I've got. {PARAGRAPH}{INSERTKEYS}Welcome to your New NLG Forums This is a free information sharing site for those of us in the amusement and gaming industry. Is it possible that the main board needs to be changed? And what do you mean "you tried swapping the optic sensors among them"? SMF 2. If you have access to another mpu board or can order one you could try it to see if that gets rid of the problem you are seeing now. And maybe sometimes turning the reset key helps with some errors. Did you miss your activation email? So it's possible something may have happened to your mpu board when you mis-connected the coin optic board that you made. According to the solution I should plug it and open and close the door. It seems the machine can't tell when I close the door. I also built an optic board with some opto couplers, a microcontroller and a switch to emulate the coin since the original board wasn't working properly. After connecting it again, the machine started to work great! I changed it and now the machine starts ok but when I close the door it doesn't reboot like it used to. So it is impossible to erase the errors that occasionally occur. You'll be getting some various suggestions on things to try. Or is it not needed because of the way your self-made coin optic board is made? Donate Here. In the lower left area of the coin optic board there is a switch you can press to put test credits on the machine. The coin comparator actually fires optic A on the optic board then B and C are fired as the coin travels past the optics. Thank you all for the suggestions. Can you post a photo or two showing the inside of the door, where the coin optics board is and the area where the coin comparitor would be? Is it possible that I broke it when I inserted the coin? Logged If you can't afford to lose you can't afford to win. Unless the Vb series diode, tranzorb, or fuse was blown. Or were you using "test credits" to play with the door open? You say you were playing it for a while before you tried dropping a coin thru the optics boards.
