I would imagine that your system has a fan installed to ensure the device does not overheat.

If this is a new device I would call the place your purchased it from and enquire if this is normal.... As there could be a fault with the fan or the temperature sensor.

If this is an old unit its possible that dust has covered the insides of the device and has caused the temperature to rise, thus causing the fan to spin quicker to attempt to lower the temperature. I would recommend taking it to an authorized repairer in your location to have them perform a clean / service.

The receiver makes a humming noise when power is on


Is it the fan making noise? Sometimes you can put a little oil on the bearings and alleviate this problem.

Benwin 5.1 surround sound system Humming loudly without anything pluged into it!!!


It is sad your having a problem with your
Benwin 5.1 surround sound system
If humming can be heard on all speakers, then it could probably

be on the power supply.


If it is only on the main SUB unit, then it could be the amp itself.

But check for power supply capacitors that supplies voltages to the

amps.Check for amp output DC voltages too.

Break this down to its most simple form.

Do the speakers work for FM and test tones?

A TV may or may not be a useful audio source depending on where the programming IT sees actually comes from, like a Cable BOx, which IS a high-end audio source.

Speakers buzz with no sound


Is this only with CD, only with THAT CD, or with nothing in particular selected or playing?

Check all connections for tightness as bad cable shield connections will let emitted noise into the system. Ditto for signal or speaker cables routed near power cables, TV's, other electrical sources.

Sometimews reversing the AC power cord polarity can resolve buzz/hum.

Loud hum when I turn on power from the speaker


Disconnect the device (amp or TV) that is feeding the speaker system. Turn on the power and see if there is still a hum. If the hum is no longer present, then the hum is most likely from the source.

If the hum persists, most likely the power supply has failed, or the output section has a short. You should contact the manufacture for support. They will most likely recomend that you give the unit in for service.
