MTH Proto Sound 1 "No Dings" on startup

PS1 parts are still available. https://www.mthpartsandsales.c...lists/200?type=lists

Oh Wow!!!!!!!!! Excellent, thanks for the info.

I just ordered both upper and lower boards for my steamer, not sure if it's the lower or upper board, so I got both for $176 with shipping.

Thanks!

Don't know 100% if that is what you are experiencing.

Just after all this PS1 talk today, I might have started with the $30 chip before jumping into the boards. I also might have double checked the tether system and the solder joints at the engine side of the connector socket since that also has been a recent failure topic.

I recognize that you did try to use the Make PS chip from the 50-1023 kit.

PS1 just seems to be one of the top topics of the last 2 days.

About 10 yrs ago I had a premier Dash8 that also did the same thing as you described.  Chip Reset only brought back 2 dings and idle sounds (stuck in neutral/reset mode).  The late Marty Fitzhenry helped me w/ my loco.  The only solution was to replace the PS1 chip.  A quick test if the PS1 chip is corrupted is if you can swap out the current PS1 chip for a different PS1 engine's working PS1 chip (doesn't matter if steam or diesel) and attempt to see if you can start up and run without problem.  If the loco operates w/ the replacement chip then purchase a comparable replacement PS1 chip.

Vernon, I just swapped out a diesel PS1 (Santa Fe F-3) and now my 2-6-6-6 Allegheny runs fine. So the chip must have gone bad. I don't mind ordering the PS-1 board from MTH Parts, as I can always use a spare and I thought they had been long gone for many years. Thanks for the help.

Glad you got it working. I failed to explain possible testing sequence in my first answer and just gave you the link to parts with very little other info. Again, good you got it fixed and have some parts on the way. The other good news- MTH parts is on it, they may go out tonight or first thing in the AM. I have a parts order that will arrive tomorrow from them.

Always best to test and isolate.  I would also state the reset chip you have is the Make PS chip.  That is only used for 3 Clanks symptom. It does not reset or do any other repairs.  You can put that Allegheny chip in your santa fe and see if it works.  But be advised the engine is an early engine and there were software differences.  So some chips only work with some boards.  G
