This is unfortunate and I'm curious to see what the final culprit is.

Me as well. Sorry for the bad experience.
Be sure and let us know what they find, and Ring will let you know. I found out today that the LM-3S I messed up a couple of weeks ago was "cause by shorting one of the motor wire to another power wire", which was my OCD trying to use the white wire on the 6-pin for a light output. I mean that's what the one on the 9-pin is for.

I too would like to know the final outcome.
Never watched Monk, but searching SMD codes to try and see what's what with the IC that we think is in question, I believe it's one of this family: https://www.maximintegrated.com/en/products/analog/audio/MAX9700D.html. This is probably more interest to Alan than everyone else. If that is indeed the IC on the board (remember, speculation it is) I imagine that given it's output rating it wouldn't take much to overdrive it.
Looking at Blueleaders pic, is it possible that the speaker was resting somewhere against the model and it could have vibrated enough to short the speaker terminals to the frame of the loco or something else? It would explain a sudden loss of impedance (I should have used that term yesterday) which would overdrive the amplifier very quickly.

Blueleader, I am very sad to hear that comment. I think you'd be much more frustrated by DCC from the outset though. Now, if the HC was faulty straight from the box then ideally either Trainworld (if you had sent it back to them) or RE should really cover your return postage. They may not be required to by law but I'd certainly be asking for it.

Yes, that is a saddening comment. It is nice to be able to remove DCC equipped locomotives from the box, place them on the rails and watch them run, but making settings modifications is a nightmare, even with JMRI. I have watched my DCC friends struggle for hours to get an engine to run the way they want it to. Don't even mention speed matching.
Installing a LM and speaker can be a challenge, particularly when hard wiring, but once that's done, settings are a breeze. I wouldn't trade RP for DCC under any circumstances. Perhaps at some point, we'll be able to buy RP equipped locomotives with sound, but I would think that is a ways off.

I'm just frustrated that after saving for 6 months I get a new HC that won't work and somehow fried a module. My Dad was an electrical engineer and excellent mechanic and he taught me everything over decades. I can and have wired a house and a 37 Ford pickup we restored together keeping the flathead V8 and rebuilt starters and rebuilt 12 ALCO Athearn PA1 all running great with led lights added and on and on. I can weld, prep and paint a car flawlessly, build my on high performance pc's, kill a deer at 400 yards with one shot in a wind, rebuild a V8 motor in a day adding a supercharger and program it with an SCT tuner, save lives with my USAF combat medic training...And I have, build a beautiful piece of furniture or restore an antique Victor Victrola...because I have, and on and on. All of this I can easily prove as skills I have and shows that I pay attention to details and have exceptional intelligence...with 2 college Bachelors Degrees in Science and a Masters to back it up 😊 So I will give it another try but if I get back a faulty HC its over and I will stick with Smart DC for several more years.

Tim will take care of you, I wouldn't sweat it. Very unusual for there to be hardware problems but it can certainly happen.
I had a brand new LM-2S fry once for no apparent reason. Same thing as you but without the melting. Everything was properly installed (I've installed tons of these) and I doubled checked the wiring. Locomotive ran fine during testing, then I just had it sitting on the track with the sound idling... Next thing I know I hear a quick screech and magic smoke coming out of the top of the loco. Quickly pulled it off the track and the module was toast.
Sent it back to Tim and he found that there was an errant piece of solder that had somehow broken loose inside and shorted out a couple things. Tim took care it and all is well.
