Dublo A4 Update

As in my last post, I recently bought a Dublo A4 from TMC. Got in on the rolling road - nothing. Firebox flickers there, nothing else. Completely dead. Took it apart to see if it was the pickups but they’re fine. Have emailed Hornby to see if I can get a replacement sent out to me but it’s so disappointing for my first brand-new model to arrive as a non-runner, especially one so expensive :(
