Audio issue 3V PS/2 Locomotive

Must be, but I have not seen any other than the board that failed while the sound file was being load.  G

I think another issue is the speaker appears to have gotten soaked with fluid as well, and it may be shot.  The board sounds great on my test set, but lousy in the locomotive.  When I look at the speaker, the cone is soaked in smoke fluid.  However, after loading the sound file, it doesn't cut out and go nuts like it did before, just doesn't sound good anymore.

New speaker coming up.

Did you happen to try different volumes with the same cutting out behavior?

Yep, turned it all the way down to off and back up again.  I don't know if it was the oil, the loading of the sound file, or just the bad speaker.  Before it runs again, I'll be getting another speaker installed.

I've never seen a sound file get corrupted after it was loaded properly.  I would suspect some already tried to load the file and it failed or something in the speaker circuit wasn't functioning.  If the wire harnesses were soaked like the rest of the engine I would think a contaminated wire connection was a more likely cause.  The act of removing and replacing the board probably restored function.  Just a guess, but it seems more likely than oil contaminated 1's and 0's.

According to John's original post the board did not work in the bench tester even after cleaning, so that eliminates the engine wire and speaker issues.  So unless a fluke were the board needed to dry off with time, the issue was resolved with a sound file load.

I have not seen a corrupt file other than once, which occurred during a load.  I have seen a few post were folks say a reload solved their issues.  Interesting.  G

I also have an issue with no sound in a Dash-9 that has PS2 upgrade in  it. It ran fine for several months.  All of a sudden the sounds disappeared, all other functions work.  I do not use the smoke unit.  An MTH tech at York said it is most probably the audio amp failed on the processor board.  Have been debating whether to upload the sound file again.  Think I will upload the sound file again this weekend.  Will keep everyone updated.

 Always try a reset first. Sometimes the board loses sound during signal tests or for other reasons, like bad track signal during adjusting. Then, a file reload may help.

 Something's going on with these files that gets glossed over here. It is not a big deal, but disturbing that it happens. Maybe just layout's signal, tiu and computer connections, and other issues making them appear?

 Sometimes when my layout is all tuned up and everything is working great, I don't touch anything. I'm losing interest in swapping files when not needed. I bought a couple more new engines and issues popped back up. Urrggg.

Glad to here a simple fix is in the works. It'd be nice if the makers went with poly speakers...more cost then though.

FWIW, I did a feature reset, then a factory reset on the board on the test fixture before loading the sound file, none of that restored the function.  That was indeed after a through cleaning of the oil off the boards, and I was about ready to toss in the towel and declare the processor board bad when I figured a reload wouldn't hurt to try. I truthfully didn't expect it to fix anything, but I remember several threads of people reloading sound files and having success, and it was cheap to do.

I have left it on the test fixture running for a few hours, until I got tired of hearing it talk to me in the background. still seems fine.  I just have to snag a new speaker and I think it'll be good as new.
