Greeting all! Longtime lurker, first time poster. Bought a LionChief Disney 50th anniversary set new in 2023 whilst in the park. Was going to just leave in the box, but my youngest daughter convinced me to run it for her. Anyway, literally new out of box....and while it runs, I get no smoke or sound even with the switches on. Contacted Lionel, they told me I'm SOL since it was covered for 1 year from purchase, which past whilst it was quietly sitting in the box . I own quite a mix of prewar, post war and modern stock, and I've had to fix repair alot. So I'm not shy about taking things apart. So I did! Checked the wiring at the couplers, nothing is broken or disconnected. Speaker is good test with known good sound source and it works fine. nothing broken or disconnected under shell. What the heck could it be?? Any ideas?  I Appreciate any input..
