I have a Visionline Big Boy 6-11437 from 2015 that is rarely used, but has always worked properly. Yesterday I powered it up and could not get Crewtalk or Towercom to speak. The loco moves fine, the smoke works, and other sound effects including bell, whistle, chuff, water injector. But pressing the Crewtalk or Towercom buttons on my CAB-2 does not produce any audio. The cab light is not blinking, and the audio still works fine on other locos. The only other weird thing is that the loco did shut itself off while powered up and crawling, unexpectedly. But then I was able to power it back up again, and this happened after I realized the speech was not working. Powered by Lionel 180W Powerhouse and Legacy Powermaster.
I did the steps listed in Lionel's "Reprogramming your locomotive to restore features" and that did not work. Prog/Run switch to Prog, Legacy base on, power up track, press ENG and 2-digit ID number on my CAB-2, press SET on the CAB-2, power off track for 10 seconds, switch Prog/Run back to Run, power track back up. The loco still runs fine, but still no speech.
Any suggestions before I figure out where to send it for service? Thanks so much!!!!
