That’s great, glad you got it working.

Thanks for the response. I jumped the gun a bit on the post as it really was a simple matter of reseating some of the connectors. I assumed it was something a bit more difficult than that because it seemed odd that sound worked but not music – I figured it was a secondary audio channel or something. Anyway, thanks and I am really looking forward to this project. I already cleaned up the interior (even found it came with manuals that were so covered in gunk I hadn’t seen them) and next will take out all of the PCBs so I can clean them up. It must have been mothballed for awhile because it is covered in thick crud – but it works great.

Congrats on getting a Moon Patrol. My record with repairing Moon Patrol PCBs isn’t too good.

So, you have sound but just no music?

I don’t want to insult you by giving you basic info if you already know what your doing. Did you do the normal stuff? By that, I mean:

• Visually inspect all the PCBs, to make sure nothing looks out of place
• Reseat all the socketed chips – or even better remove them, clean the legs if needed, and reseat them
• Make sure the ribbon cables look OK and are seated
• Check the voltage…make sure its 5v (or 5.1 ish)

I usually do that type of thing first before I try to troubleshoot further. If you still have a problem after that, I’d get the manual and schematics from CrazyKong.com. The manual shows the DIP switch settings. There is one for test mode. I’d put it in test mode and see what it reports on screen. Page 5 of the manual tells you how to do the tests and what they mean. One of the entries in the sound test is for the background music, opening music, ending music, etc… I’d test those. Page 10 in the manual actually has some good info on how to resolve sound issues. The last line on that page says that if sounds 2-6 are missing, chip 1F is faulty. Any other sounds missing or duplicated – Chip 1J or 1F are faulty. So, you may have an issue with 1J or 1F. I *think* those chips are on the CPU Board based on what I see on that page.

Thanks!
