Question about Denon Audio Players & Recorders
Loose connection or cold solder and cleaning problem this is the main caused of no sound..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
or loose. It is possible that the cold solder is still minimally
(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
provides electrical contact. Jarring the unit creates movement inside
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....

Self-powered would work but it would have to run on full-range amplifier (from the speaker posts) or Line Level signal (from the OUT RCA jacks) because this unit has no Sub-specific output. It's no bigge as the sub would naturally discard the higher frequencies via its own amp's and speaker
