I suspect that davenn is correct regarding an AC to DC converter - I am trying to source a replacement and will post a pic here of the working component. However, without a schematic or at least a reference board it is next to impossible to say which replacement componnet should go there. ![]() It may be that this piece of metal is the cause of the problem. I did find inside the unit a small piece of metal which looks like it has broken off somewhere, but it doesnt seem to be from any part of the trainer and presumably entered the unit on assembly. You can see in the picture that the resistor is right next to the mains power input, and could therefore be acting as a fuse to protect the rest of the circuitry. The attached photo shows the problem - a blown resistor (R64). Apparently it is not, but I am having trouble finding the receipt so may have to attempt a repair.
