No railsounds or command control

This was upgraded with aftermarket TMCC or Lionel parts?

 

First off, if you lost control through the TMCC, it's probably not the RailSounds boards.  The locomotive will run without those two boards installed, so you could simply try that without them and verify that's not an issue.

 

Are you sure this doesn't have the modular electronics with the R2LC and DCDR modules?  How about pictures of the rest of the boards?  If it's a 3rd party board like the TAS or Digital Dynamics, that would be useful information, and would change the corrective measures.

 

Hello...thank you for the response...there is a RS steam motherboard c2003 by digital dynamics installed in the engine...it looks to have been used with lionel parts...i will post pics...again thank you

If you had the DD RS MB in the engine, you probably have the DD TMCC module as well.  They use the R2LC from Lionel as the receiver and provide the motor driver functionality.

 

One question, does it run in conventional mode if you power up with the TMCC command base powered off?

Yes it functions conventionally. So then i guess the lcru2 is not fried or anything. When the tmcc is on it dosent recognize it.

In that case, I'd be looking at the TMCC antenna, make SURE it's not disconnected or grounded.  What does the electronics package look like?

I would try to re-program to restore functions.
