I have an odd failure of a RailSounds 5 board, one that I confess I've never seen. This is on the Lionel scale Cab Forward with RS5.
The tender responds to whistle, bell, and crew talk. However, I get no idle sounds and no chuffing. Initially, I thought it was the chuff switch, but I should get idle sounds. I swapped a different tender, and all was well, so that gets me into the tender.
The bottom line is some sort of failure of the actual RS5 board that only affects the steam idle sounds and the chuffing. I reseated the RS chips, that fixes a lot of oddities on these boards, but no change. I popped a RS4 steam board in, and everything worked as intended.
I moved the chips to another RS5 board, and we're back in business. Since all the sound is really triggered by the same serial stream from the IR receiver, I'm at a loss as to what hardware failure on the board could result in these symptoms.
Has anyone else seen a failure like this?
Second question, I can't seem to find a number to order a blank RS5 board. I know they must be available, as I previously purchased one and that's how I was able to repair this locomotive. I want to replace that board as it's clear I should have a spare.
