Spy Hunter Cheap Squeak troubleshooting...

[modessitt]

Power LED is lit. No Peter Gunn music plays. Normal game sounds play just fine whether this board is connected or not.

I have tried the board in another known working Spy Hunter, and it does the same thing.

I guess I can check the pinball repair site for some Cheap Squeak repair tips, but anyone got an idea as to the problem?

How are the voltage readings on the test points?

If the LED is ON and you aren't blowing any fuses, it almost sounds like a low voltage, or no voltage to the proper places type of problem to me.

Keep in mind I've only fixed one but if you need me to check anything on my cheap squeak for reference just let me know.

I seem to remember there being a chip that fails and is usually the cause of this. Can't remember which one though I believe if you search you will find mention of it.

Where's the amplifier for this thing - is it on this board? I know it will play the music if you push the button even if the main board is bad, which should mean I can bench test it with just power and a speaker, right? Or will I need an amplifier?

The amp is a separate board that mixes the signal form the CSD and the SSIO. I might be crazy, but I think that led is supposed to be OFF under normal operation.

Power led on mine only comes up at start up and blinks a few times then off. Mine seems to play the peter gunn fine.

yes that is how it's supposed to be. Missed the part where the LED is staying lit.
