I have a early released MTH Premier PRR Q2 that lost all of its sounds. I have tried all the basic troubleshooting I can think of to fix it. (Reset engine to factory default, replaced the BCR, checked the wiring in the tender for any cut or loose wires) The speaker does not appear to have the delaminating issue that some early PS2 speakers had. The sound board is not in the tender and I don't know what else I can check beyond what I have already looked at. Any suggestions would be great before heading to a service tech.
