Question about Audio Players & Recorders
I have a Pioneer Hi-Fi system and now the audio works intermediately or not at all, I think I haveisolated it to the amplifier A-Z370(I think).
Things that I have tried:
I experienced something similar.
Symptom: After use the sound cuts out together with a mechanical click (relay sound). Turning off and waiting a bit before powering on, tends to 'fix' it, but the sound cuts out in the same way after a while.
The click led me to the little relay board inside. Inspection of the solder joints showed that a few were 'broken' ("cold soldered"). This was right below a high-wattage resistor, possibly the cause of the stress causing these random disconnects.
Fix: Resolder the joints.

PioneerPards, You said it is working intermittently. You jumble up your system pretty good. You know what you are looking for. Try hooking up your speaker to the amplifier and put a signal directly into it...could be a CD player and run it till it stops. don't worry about the sound for now if it is dry without your spices. while at work, give it a tap ocassionally around your AMP. if it stop and go, then your problem is the amplifier. A dead AMP will not work at all whatsoever. Since it works sometimes, could be a dry joints (Cold solder...check pcb solder. If the amp is good for a couple of hours or so (Pumping hard occasionally), then the culprit maybe from one of your spices...EQ's and processor whatever in between from source to Amplifier. Hope this will help.
