Does anyone know a error that comes up on my MM saying sound board interface error ?
Thanks
Is that on the new MMR??
(sorry, I couldn't help myself...)
I have never seen or heard of that error message. Any DMD screen capture?
You're probably done so already but I'd pull and re-seat the ribbon cables and other connectors to the sound board.

Thanks ,I already took out the sound board and replaced it with my CV board and change the roms but same thing so I but the old board back in ,so I have unplugged all the cables ?
What CPU ROM version are you running? Did you change that recently?
I've seen that on some machines when you change the CPU ROM but not others. Could also be something else loose on the CPU, if not the ribbon cable.
Sound board interface error means there is a communication error on power up between the CPU board and the sound board. Start by reseating all your ribbon cables and makin sure the red line is on pin 1. If that doesn't help, swap the ribbon cables with your CV.
The other error is a switch error. Get the manual out or download it from ipdb and locate the l-gate switch on the switch locations chart. You can use switch edge test in the diagnostics menu and manually toggle the switches with your hands to debug.
Thanks I will try that and let you know ,I do have the manual and looked but I don't see the L gate on there?
Thanks again
L probably stands for left. Maybe the left orbit gate that opens or closes to keep the ball in the pops when shooting the right orbit.
If you just changed the 5 sound roms and now have that error then I'd say that is likely your problem
L gate error is because the machine has not detected all loop switches activate in succession recently. Normally hitting the loop switch on one side activates the opposite side gate (near top inlanes) to open and continue the loop. Then it looks for switch activation on other side to indicate completed loop. The only time the gate stays closed is when you complete a joust series.
Make sure your gates are opening in coil test and all loop switches are working in switch test.
Agreed. If you had no error, and changed the sound ROMs and got the error, that's pointing right at the ROMs.
If you've got a programmer, verify them. Or, erase and reprogram.
If you purchased the ROMs programmed, I'd ask the source to verify them for you.
I got the 5 roms from a programmer and it didn't change anything when I put them in ,until now ,the game has always had sound going off and on so we thought it was the roms but it's not ,so I try the ribbon cable first and see if that helps and I will look for the L gate switch if I can find it ,I already but it in the test and still can't seem too find it yet .
Thanks guys ,let u know what happens

Hi ,I reset the ribbon cables first and I play one long game and so far everything is good ,I will let you know what happens and I L gate I found out it is the loop test for the all gates so I just but it tough it's test and the . Is gone .
Thanks so much for your help guys
Hi guys ,the sound seems to ok for now but now all lights on PF went out ,any ideas too look for ?
Thanks
I have been working on it lately and no PF lights ,I check all fueses they are all ok when I was playing with the wires it came back on but with no flippers working so I shut it off and back on with no lights again or flippers ,I think it's playing with me lol any ideas too try guys
Need better details. Which lights are out? Inserts? GI? Look in the manual for which connectors control these things and reseat them. "Playing with the wires" is not helpful information. Which wires exactly? If you don't properly describe your steps and symptoms, no one can help you.
Flippers are dead. Is it the flipper switches or the coils? Do they fire in the coil test menu with the coin door closed? Do the switches register in switch edge test?

It's all PF lights all of them so I unplug them and put back in and still not coming on and as for the flippers the coils are not working also ,all fueses are good and all wires have been reset and still not coming on ?

Sorry but this still doesn't give needed details. Playfield lights are completely different if they're inserts or GI. "All wires have been reset" lacks all detail in what you did specifically. The way this needs to work is you need to provide huge amounts of detail. Exact plugs you reseat, how you did it, pictures, etc. what are state of the three LEDs on CPU board? Do games start? Is there sound? This is just too jumbled and you have too many unrelated problems to be brief. You may have a ribbon cable plugged in wrong. You may have fuses out (saying the fuses are fine isnt enough. How did you check them?) Perhaps the transformer power isn't hitting the boards. Without details we can't tell.
Ok I will try ,everything on the PF as for lights are all out so no lights at all ,so at thing point I reset all plugs in backbox and that didnt work ,so for the CPU top light is not on #2 is blinking fast and #3 is on full ,I don't know what this means ?
And as of now game turns on but no lights on PF at all and will not play a game as the flippers don't work ether so the first ball won't come out ether ?
Still a lack of data and it doesn't feel like anything I asked for was answered. All you have was the state of the CPU lights, which indicates the CPU did boot and has power. So there's that. I suspect fuses are out and/or ribbon cables are plugged in incorrectly at this point. Nothing stated above has convinced me otherwise.

Hi ok what I just did was unplugged all 4 ribbon cables and plug them back in nice and slow and made sure they are right and turned it on and now everything is working great now so I played one long game on it plays great so far so I will play lots more games tonight and I will let you know if everything is still ok or not .
Thanks so much
Chat soon

Update ,I have played 6 long games on it and so far very good ,thanks so much for your help ,I will keep play it to find out for sure
Thanks again
Happy flipping

Hi ,I have played many and many games on MM and everything seems to be great
Thanks so much for your help

Glad it's working
Quoted from markmon:Glad it's working
It must have been the ribbon cable ,thanks again you have been a great help
Take care
William
Quoted from playernumber4:The joy of "old games" (in terms of old connections)!
No I just had it plug in not right that's all
Quoted from markmon:Glad it's working
Update ,I have played 30 game plus and working 100% ,thanks you again your the best
Quoted from markmon:Glad it's working
Hi ,it's been working great lately until last night ,do you think I need new ribbon cable ?i just don't know which one i need ?
Thanks

I think I would remove each ribbon cable and clean the contacts on the board then blow out the ribbon cable with an air compressor and reinstall. What other games you have? Having your collection filled on would help.
Did it start working after reseating the ribbon cable or another connector? If a game starts working after you reseat a connector, it's not fixed the connector is bad.

I do have a CV that's the same ?i will clean them and reinstall .

Hi,I just ordered all 4 ribbon cables so when I get them I will change one by one too see which one it is ,if its that
Thanks
Quoted from markmon:Yes, cv is the same. Feel free to swap between them
Ok ,they should be only a week too get here I will wait for them and I will let you know what happens .
Thanks so much

Hi ,ok I got new ribbon cables now ,I put them in and it's still doing it so I guess it's not them ,what happens is when I am playing a game the sound will go off and then come back on very loud and other times it will do the same but with all light will go off also ,then there's other times I could play 10 full games with no issue ,any ideas
Thanks
William

Hi ,did you get my last email
Thanks
Quoted from markmon:Yes, cv is the same. Feel free to swap between them
Hi I got new ribbon cables and that didnt work ,when I am playing a game the sound will go off and come back on but very loud and the video will go all fussy ,some times it will be fine and I can play many games ,At first start up it would do it also ,ant ideas
Ok. Here is what I would try. You have a cv sitting right next to your medieval madness. These two games have the exact same board set. So swap these boards one by one until you can get the problem to move. Swap them in this order:
1) wpc95 av board. This is the one with the sound cables plugged into it. Remember you need to carefully unseat and move the 5-6 sound roms when you make the swap
2) power driver board. This is the big board in the bottom. No roms to swap
3) CPU board. Far one on the left. Need to swap the game rom and security chip.
Careful you don't bend pins when prying the chips out and that you don't put the chips in backwards. Swap one board starting with #1 above. Play until you can reproduce the problem in either game. If the problem moves to cv, you're done. Report back here.

Hi,ok thanks I finely changed the power board last night and that was it ,so I have the board in too a good friend too be fixed .
Thanks so much for all the help
