Sounds

Assuming that the other unit is working correctly, you have nothing to lose by swapping the boards.  Since they are the same there is no reason to reprogram anything.  Put the defective parts in the working locomotive, one at a time.  Start with the sound board.

The static sounds are a classic issue.  Top suspect is actually oxidation of the contacts on the two RailSounds PLCC chips on the sound board.  Reseating them fixes many of these issues.  I do this once or twice a month on repairs that come in.

One warning.  Do NOT try to pry these out with anything but the proper PLCC Chip Extractor tool.  You can search for one on Amazon, they start around $5 with Prime shipping if you have it.

Hi I have a Lionel LC+ Hudson that is 2 years old it makes a strange sound when I first turn it on. All the normal sounds work just fine but the strange sound keeps going. As soon as the loco runs at at a normal speed the odd sound stops and all the normal sounds work fine.Do I have to replace the sound boosrt or is there a fix for this? Let me know. Thanks

Wayne I opened my locomotive that I was talked about in the first post I put here I just removed all the boards and cleaned them and the motherboard and reseated them. That took care of all my sound issues that I was having. I also had the same problems with another SD40-T2 6-28225 SP #8521 so I did the same thing with it and that took care of all the sound problems with that locomotive also. I hope this helps you also with your issues.

Gary, the LC+ engines don't have a separate sound board, so that "cure" doesn't really apply here.

John the locomotive that I have has a 691R2LCC08 R2LC / R4LC / RADIO RECEIVER (C08 CODE) and a 691RSPRA00 RAILSOUNDS     4E / SPSF SD-40T-2 #8521 and a 691RSPRA00 RAILSOUNDS POWER BOARD / UNIVERSAL they are all attached to the Motherboard. The Railsounds boards in no longer available from Lionel. All I did was remove them and clean them and reinstall them and that corrected my issues with all the sounds.

Gary, now go back and read my comment.   Wayne has an LC+ engine, that does not have any of those boards.

What did you use to clean them?

I don't understand the question.
