I purchased a Lionel Summit View Stationsounds Dome (1927230) about 2 weeks ago. I tested it out at the San Diego 3-Railers layout yesterday and was having issues with the car responding to commands. There were a select few parts of the layout where it would respond to a command but like 5 seconds after I pressed the button, I got absolutely nothing with the layouts Cab-1Ls too. At home I had 0 issues with issuing commands, it responded correctly.

Although the above issue is now irrelevant since the car no longer responds to commands anymore. At one point while I was running it at the layout the black wire for the hall effects board got snagged on a switch and that seems to have bricked the RCDR. Now all I get when powering up the track is just air brake application sound effects. Trying to even as much as program in a new TMCC address does nothing.

The black wire got snagged on a switch because someone at the factory routed the wires to they go through a hole in the truck, run under the frame of the truck, and then connected to the hall effect sensor. I have gone and rerouted the hall effects sensor wires so that they will not have a chance of snagging on switches again, running them inside the truck instead of under it.

With the above information, can anyone confirm if the RDCR is dead?

Edit:

I checked the car with the lights off in my room, the interior lights no longer come on either. The sound card is still showing some life, with the air brake application sound going off upon power up and then having the 60 Hz buzz emitting from the speaker

Given the nature of the short to AC from a known DC sensor wiring, not to mention the voltage difference, you probably did kill something. The 60 HZ hum is indicative  that a failed component might now be drawing current and or passing AC that is making it to the amplifier.

The #1 rule in modern electronics in these trains- most any brand, any sensor or output- even switches probably can never ever short to frame ground without blowing the electronics. This is because they rectify full wave to DC so DC ground is NOT the same as AC ground and any short injects high voltage AC back into low voltage DC only circuits killing most everything.
