Hey Guys,
I have a Q*Bert sound board that is a bit screwy. I thought I was only missing one sound but I am actually missing a lot more. Some sounds don't play, others are wrong. When you play the game, if you didn't know how Q*Bert should sound you probably would never notice the difference.
It does say "Hello, I'm turned on" when you power it up. Most game sounds work, but the speech seems a bit off. This video is from MAME and shows how the sounds SHOULD be:
This is how mine sounds:
If you compare both videos, you'll start to notice the difference with sound 04 which my Q*Bert doesn't make. Several other sounds are missing, and the speech doesn't sound right.
I've seen the Q*Bert sound flowchart, and have been using that as a guide.
Details on what has been done so far:
Anyone have any ideas here?
Thanks!

Details on what has been done so far:
- Power supply board has the zener diode mod, and voltage is OK
- Filter board has been gone over, and I believe it is OK
- I tested all the connectors on the filter board
- I replaced all the sockets on the sound board
- I replaced all the caps on the sound board
- I replaced A10 on the CPU board
- I replaced U16 on the sound board
- I just replaced U17 on the sound board
Anyone have any ideas here?
Thanks!
