I was wondering if someone could shed some light on a diagnostic procedure for non working stereo equipment? I know this seems like a loaded question so I will attempt to clear it up. If a piece of equipment is completely inoperative we know that we have to check fuses and verify power and grounds, however if the equipment lights up but has for example has no sound on fm where would one start? This is not for a specific model it is just a general question in attempt to better understand the flow of diagnostic procedure. Is their something in the service manual that describes the flow ( is this possibly what the block diagram is and if so could someone please explain how it works ). Generally there is a clue that one could see like in the example about no fm, does the tuning meter respond, does the fm light light up etc and then one could start checking voltages on the tuner board and pin out values on the ic chips etc. I mainly work on Pioneer equipment hence I posted it in this forum, I hope the question makes sense, if not please respond and I can reword the question or respond to the replies, thank you for all the people who take time to read and respond to this question, I think it will help myself and many others.
