APT Fan Posted April 24, 2023 Share Posted April 24, 2023 Evening, I fitted Hornby R3957 power and trailer cars with TTS decoders a few months ago and everything was working fine. It's been in a box since then whilst I've been preparing a new layout. I tested it on the new layout over the weekend and the power car has no sound now. On inspection after opening it up I noticed that the wires to the speakers have been nipped slightly by the daft retaining screws. Wire continuity is fine between the speaker and the pcb, so I'm thinking maybe the output stage is blown? Are there any further checks I could possibly carry out? Thanks in advance.
