Question about Marantz Audio Players & Recorders
Lights are there and have power,you check already all speaker are good,then the problem is loose ,or crack or cold solder...
No sound problem is power amplifier trouble maybe the IC there is defected or cold solder of joint of the parts.Cold solder issues - each component is soldered into small holes on the printed circuit board which in turn connects said component to the other components. Due to time, heat, use, some solder joints would be cracked or loose. It is possible that the cold solder is still minimally connected (hanging by a thread). When the receiver turns on heat would be generated which would be sufficient to further loosen up the solder joint to the point it no longer provides electrical contact. Jarring the unit creates movement inside enough to re establish the contact, sometime good enough sometimes not enough.
Again, since the unit still operates (sometimes) then it is highly probable that there are no defective components. As you have surmised, it is possibly a loose connection, solder joints are "connections" except that molten soldering lead is used to attach/connect the component to the board, "loose connection" in this sense is equal to "cold solder".
Again on the assumption of no defective parts, then seeking a more experienced buddy for the soldering might be to your advantage. This is of course in addition to the possible electrical hazards when repairing....If i have helped,please click fixya.It is the only way i get paid for my work...
