Hello Innocent, it would be good to describe your Panasonic HiFi model, also says that other equipment is connected to Panasonic, this way I can know better which teams are commenting and offer you some idea so you can solve your concern
I wait your answer
Greetings Franco Dosil
Hola Innocent, seria bueno que describas modelo de tu Panasonic HiFi, tambi?n comenta que otros equipos est?n conectados al Panasonic, de esta manera podre conocer mejor de que equipos estas comentando y poder ofrecerte alguna idea para que puedas solucionar tu inquietud
Espero tu respuesta
Saludos Franco Dosil

reverse your cable if the problem go to right speaker you have a problem in your amp and needs to fix-if the problem still in your left speaker you will have a problem in left speaker itself(cables or speakers)-start with cable changing and then speakers,

You've done your homework on eliminating potential external sources so one of the few things left is a failed filter capacitor in the power supply of the unit.
'Hum' is one of the most common signs of this.
If a capacitor fails catastrophically, there are normally visible signs of it.
If you are adventurous, you can invade the subwoofer box where the supply and amplifier are probably situated and look at cylindrical parts in the area closest to the AC input.
The supply will be in whatever case to which the power cord is attached and the bigger box is the most likely candidate.
Capacitors of this kind can be in size from a 1/4 of an inch to 1 1/2" in diameter, have a plastic sleeve around them that is normally open at the top where the aluminum of the case is visible and they are mostly installed vertically in the board.
These often (but not always) have 3 scored lines radiating from the center.
Check around each of these for any signs of crusty deposits and on their tops, look for signs that the top has bulged.
If you find any looking like that, they are probably defective.
There are values on the sleeve that will be in 'uF' and voltages expressed in DC; i.e. one that bears 47uF/16VDC needs to be replaced with that same value.
If you make it that far, you will need only few tools but a decent soldering iron to remove the failed part and pay attention (marking is best) where the + and - leads go since they will fail and make a mess if improperly polarized.
If you do not see any with the signs of failure described, the only recourse is to find a tech with a capacitance meter necessary to find the failed part(s).
Since the cost of repair by any shop would exceed the replacement cost of a new set, you may end up contributing to a landfill.
