Hi @tcole85948

Does it work OK when using 6 x AA batteries inserted into the synthesizer?

''If it does'' it could be a faulty DC-In jack where the adapter plugs into.

''If it doesn't'' then it could be a faulty power on switch or something further into the circuit.

Here's the [document|42140|schematic] that may help
