I know this is a cheap unit but my daughter loves it anyway everything works but the unit has no sound. I can't find any service manuals for it. When I scope it there is no audio from the pre-amp plug or for that matter I can't find audio anywhere no matter what source I am using. I am thinking it is a missing voltage either power supply or micro but with no schematic I have no clue. If anyone might be able to help thank you.
