My Star Trek next generation pinball has no sound with two different sound boards. Both boot to sound board interface error. I bought and installed new sound board and cpu roms in known working board. Both boards do the same thing. The ribbon cables I swapped out with a know working game and the sound works fine in Indy with that cable. I checked power and grounds to the sound card and they are fine. I do not know what else to check or try? If I put a pinsound board into it the game has sound and plays fine. Any suggestions would be great. I am two steps away from just buying another pinsound board, but wanted to see if anyone had any suggestions first???

Check the header pins the ribbon cable connects to? That's about the only thing left.

Did you try putting the new board in your Indiana Jones with the Indiana Jones chips in them to verify that the sound boards are good? This is a double check to verify the sound boards are good. The cpu rom chips will not have effect on the sound board error. Replacing the sound rom chips usually, but not always, fixes this problem.

I swapped sound board with my indiana jones machine, transferred the roms over and the sound board works fine in indy and I know the indy board works and that is now in sttng and it does same sound board interface error. I bought a rom set and it came with all but u8. I talked to supplier and he said to use my u8 rom. I really think its a rom issue. I am going to try and get a new u8 rom to eliminate that as cause. I swapped the cables for the 2 machines as well. Thanks for any ideas. Its driving me nuts!

No need to swap the sound ROMs when you swap sound boards between games. It will not hurt anything, but obviously it will give you wrong sounds and speech. Moving the sound ROMs with the original sound board over to Indy will help to prove the sound ROMs and the sound board are good. You can even move over the Indy sound board with Indy sound ROMs into STTNG to see how it does.

Try reseating or swapping this ribbon cable. Different sound board in picture, but that does not matter as it is for just reference only.

did you order the silly roms? that is the only reason you would not have been supplied with a u8 .

I ordered original roms and it turns out he sent me silly ones. He is sending me the complete original roms today and I believe that the problem is in the roms. I swapped everything between the two boards and error message follows roms. If new roms dont fix it I am just going pinsound as its not worth any more effort.

Don't you have an original STTNG sound ROM set that was in the game?

The original sound board roms developed green powder in sockets and rom pins. Sound would cut in and out during game play. Looked like acid damage guessing something let go on board and it was not cleaned up by previous owner. I have had a pinsound in it for a few years, but I moved pinsound into a game I just sold. Figured I would try and fix original issue or worse case just buy another pinsound.

I did clean the rom pins, but I think when it was cutting out one or more got damaged as it made funky sounds and then quit all together. The board was severely damaged and The lower corner was in very bad shape. I cleaned it up put new sockets in board, but it has same interface error. It might work with new roms. I will post end results as I get there.

A new set of roms fixed the issue. It seems the first set I bought are no good as the replacements work fine.

Quoted from Loganpinball:

When it wasn’t working at all were you getting the startup “bong” sound at least?

I am having a similar error with my sound board. I’ve reseated and even replaced the ribbon cables and verified AC/DC voltages to the board. I don’t even get the bong sound.

I have another board en route to my house in addition to a pinsound+ (we’ll see which gets here first).

Both boards had interface error and both did not make start up bong sound.

I was also not getting the bong sound. Got another DCS board from eBay and swapped my roms into it. Everything is working again.

In my case it wasn’t the roms.
