I am having an issue on Earthshaker where one of the call outs is very, very slow. Almost like its running on dead batteries.
Do I need new sound roms or is this a board issue?

I will try this. Thanks
What is situ?

Unfortunately this did not help.
What should I do next? Would buying new sound roms help?

How do I test lights or sound?
I can find audits and adjustments, but it ends there.

I don't have a manual so I didn't realize the test switches in the back.
When I hit the sound test, it just beeps 3 times over and over.
When I hit the cpu test I get this on the display.

Thank you for this, I searched for a manual for a while with no luck. I am on it.

Ok, manual says 3 beeps means U4 chip problem. Would replacing that sound chip fix it?

Ok, so I misread the beeps on boot up as SW1 test results. I am getting 1 beep at boot up.
Ran SW2 test with coin door open and did not get a failure back.
Going to replace U22 chip per SW1 test.
Thank you for the guidance

Thanks again, will post once I get the rom.

So I put in a new U22 chip, and I ran the SW1 test. It still beeps 3 times indicating a problem with the U22 chip.
Not sure what to look for now?

Thank you, the socket was my first thought. Does reflow just mean to heat up to fix any cracks or add new solder?

Yes, its still doing the samething.
