gstewart24 Posted March 17, 2013 Share Posted March 17, 2013 I have a Dixie Narco 2145 glassfront that is giving me problems. I noticed the other day that the MEI credit card reader was saying cash only and then it wouldn't take money at all. I restarted the machine without the easytrak system and the display shows the version # REVB 30.01, but nothing else after that. I can't use the mode button or anything for that matter. So I replaced the main control board with an updated 5591 board, and the display doesn't show anything at all. It just makes a beeping noise. I am so confused. I called Dixie Narco and they said I have the wrong board for the machine, but The Vending Center says that the 5591 board does work with the 2145. Could I have a different issue here that could be causing the machine the machine act like this? I have power to the board and the rest of the machine. Display does seem to work with the old board because it scrolls the software version only. Thanks for your help Link to comment Share on other sites More sharing options...
Walta Posted March 17, 2013 Share Posted March 17, 2013 I would start this way 1 Put the original board in the machine. 2 With the power off unplug all the connectors except power and display. 3 Does the board power up? 4 If yes power down and add connectors one at a time until it does not. If I remember correctly they are the same board but deferent software. You can try swaping the EPROMs. Walt Link to comment Share on other sites More sharing options...
AZVendor Posted March 17, 2013 Share Posted March 17, 2013 Follow Walta's suggestions of how to isolate the problem. You may find that one of your MDB components is bad. MDB is lke USB on your computer where everything is daisy-chained together and any one MDB device can cause a problem with the machine. You may also actually only have a bad display or display harness. The only way to know that is to try another display and harness that matches the one in your machine now. There is also a difference I have run in to with display boards between the 2145 and 5591 machines. If a 2145 display doesn't solve your problem, then you should try to get another 2145 board (it's the longer one) and use that. If you have to use a 5591 (shorter board MDB only) then you will need to get the later display board and matching display harness. Link to comment Share on other sites More sharing options...
gstewart24 Posted March 17, 2013 Author Share Posted March 17, 2013 Thanks guys. I'm new to the board and I'm sure glad I found this site. I put the old board back in and still had the same issues. The display reads out the software version then goes blank. The new board I had was a short one. Dixie Narco is sending the right board (long one) to me. Hope that fixes it. If it doesn't, then I think I have a bad display board. I did try swapping the EPROMs but that did nothing. Oh well , any more ideas? Link to comment Share on other sites More sharing options...
kiwi Posted March 17, 2013 Share Posted March 17, 2013 The 5591 board should have 030.61 software (eprom) or above which is not compatible with the display that you have in your 2145. If you are wanting to use this board & software you will need to upgrade your display & display harness which is going to cost you more.. When you say that you tried swapping Eproms did you put the "new" Eprom in the old board or the "old" Eprom in the new board? I would think if you put the old eprom in the new board it should work but if you have tried this & it hasn't been successful then maybe you mite have another issue.. Do you have anything on the display now when you try either board or is the display blank? Link to comment Share on other sites More sharing options...
gstewart24 Posted March 18, 2013 Author Share Posted March 18, 2013 Display is blank. When I put old board back on and restart the machine, the display comes on and just scrolls software version then goes blank. Link to comment Share on other sites More sharing options...

Ok.. I just want to confirm that you tried the new board with the old eprom that you removed from the original board & it still didn't work when you connected it?

kiwi Posted March 18, 2013 Share Posted March 18, 2013 Did you also remove battery clip to allow the board's memory to drain before replacing eprom? Link to comment Share on other sites More sharing options...
kiwi Posted March 18, 2013 Share Posted March 18, 2013 Hi gstewart24, I was just looking at an image of a 2145 board on vendorsequipment's website & it looks different to the board I have in my 2145 so you mite have to disregard the comments I made. The control board I have in my 2145 has Dixie-Narco 804,914,420.11 written on the board beside the door switch plug. This is the same board that I have in my 5591 models which is why I thought you had the same board. Sorry mate.. I think I better leave the advise to the experts Walta & AZVendor!

AZVendor Posted March 18, 2013 Share Posted March 18, 2013 One thing I have learned about Bevmax displays is that if the display won't work at all, the machine still vends properly, and a new display board also won't work, then the power supply transformer is probably bad and one of it's outputs is low. I chased this problem for a week in a 2145 changing the board twice, the display twice, the eprom, the display harness and finally found one output from the transformer had low voltage.

I was thinking the transformer may be bad. I had some guys at the factory where the machine is at check the transformer, and they said it was fine. Had 24V coming out. I have no idea how to check that transformer for low voltage. Should I take it to an electronic store and have it checked? We also metered the pins from the plug coming out of it as well. This machine has gotten the best of me!!! Did you also remove battery clip to allow the board's memory to drain before replacing eprom? No I didn't remove the battery clip from either board. Should I have done that? Link to comment Share on other sites More sharing options...

No I didn't remove the battery clip from either board. Should I have done that? I don't think you have a transformer problem per se, I was primarily informing everyone what the underlying problem could be it the display was not working at all. You have said that you get the startup wording of the software version number, so I think your transformer is probably ok, but you should check your output voltages anyway. Here is how to measure the voltages: Turn off the power switch or by pulling the incoming power plug at bottom of power supply (on back wall of coin compartment). Pull the white harness connector on top right corner of face of power supply, it is a 9 pin square connector. Turn power back on to the machine The pin numbers on the female connector coming from the power supply are 1-9 beginning at top left for 1, top right is 3, middle left is 4, middle right is 6, bottom left is 7 and bottom right is 9. Using a voltmeter set to an AC (not DC) scale above 120V, these are the pins to measure across and voltages you should see: Between pins 1 & 2 = 24VAC Between pins 1 & 3 = 12VAC Between pins 2 & 3 = 12VAC Between pins 4 & 9 = 24VAC Between pins 5 & 7 = 115VAC Between pins 6 & 8 = 115VAC All readings should be real close to those listed, 12V reading shouldn't fall below 11V, 24V shouldn't fall below 22V. I don't know if you said whether the machine actually still works or not. If the display goes bad or the display driver for it on the logic board, then the machine should still vend even though you can't see anything on the display. If the machine won't vend at all, then the display of the version number and nothing else indicates the board is failing its bootup procedure and you need to replace it.
