New Life Games Tech Forums

I started this new thread so I can stress how odd this issue is to me. Half the sounds are again missing although game play seems to be okay. I was also getting pixelized graphics on the screen before I decided to turn the game off. I have since turned it back on and the screen looks fine but the sound issues are still there.
I've unpluged every connector and used contact cleaner with no change. I do not believe it is related to a specific game chip as the issue spans multiple games and I didn't change anything on the board when the issue arose.
If this is a power supply issue, it hasn't been tested yet due to my lack of electrical knowledge but with the pixelized graphics, I'm leaning that way. Does this sound logical?  :103-
Hope someone has an idea.
Thanks, Jim

The only thing I can suggest is to check dipswitch bank 2 and make sure the 2nd dip is off, this is for Deluxe sound and it could cause a problem.

Thanks,
Checked the dip switches and they are all off. Moved the #2 on and back off to make sure and no diffence.
Thanks for the suggestion, Jim

I pulled my PS out and found it is using a Phihong model psa-4031 universal PS.
Here is a link to the stat sheet:ftp://ftp.jameco.com/Archive/Current-TechDocuments/189536.pdf
Copy and paste the link starting with the first ftp. This web site kept adding http// even though the link doesn't use that. I know it's confusing. Sorry.
Should it have a different PS or is this okay?
Should it be using the replacement for Bally (80-1178-00) or does it matter? I've been using this PS for about 4 years now and had no real issues until now which I haven't determined to be the PS for sure.
Thanks, Jim
