Since day 1 that I got my Time Warp, the sound has not been working 100%. The chime function works and 'some' sound effects work, but not all. I thought maybe the sound board had some bad components on it, so I bought an 'untested' one and, although it appears to be in significantly greater condition, it's doing the exact thing the original one did!
In the marvin3m guide it says you should be able to put a lead on a ground with your DMM and then touch one of the pins at location 10J3, and you should hear individual sounds that are getting ported from the sound board. When I do this I get no sounds at all, and that's in either attract mode OR while a game is on and the connector is removed.
I checked the 3 pins on the power input connector (at 10J1) and they are getting 9V AC as they should.
I checked the 2 fuses on the board with my DMM and they test good.
If I press the sound test button in the upper right corner of either sound board, I get the repeated cycle of sounds so, it's definitely pushing sounds to the speaker.
If I run the solenoid test, I should hear 5 sounds generated using solenoids. I hear all 5 sounds generated correctly.
Anyone have any suggestions at this point? Could it be that I now have 2 sound boards with burnt out PIA's or 6802 chips? Right now it's pretty much the only main components I haven't troubleshot yet.
Thanks!
