I have kenwood amp m-a100 which has loud buzz / hum on all channels and distorts radio very badly can you help ?


The loud hum will be probably caused by the Large Electrolytic Capacitors in the Power Supply section. All of them will need to be replaced to be on the safe side. The buzz noise is caused by the fact they are letting in the 50/60hz mains. Hopefully that should clear everything up.

Apart from the suggested solutions shown below, you might also want to consider the turntables power supply as the cause of the hum. Perhaps a faulty mains smoothing capacitor?

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.

Loud hHum from Subwoofer


Sounds like the hum might be mains hum caused by the failure of the power supply capacitor(s) in the sub. It/they will be the largest on the pc board. You will find all the details (needed to replace it) on them. If you find more than one replace both.

GU1500XTL loud humming sound during the cycle, getting louder


The run capacitor on the main wash motor needs replacing. Eventually it will just hum and overheat instead of rotating, so better replace it now before it overheats.

I doubt you can acces it easily yourself, as it may be away from the motor, and have to be tracked down.

Pioneer Receiver SX-750: Getting a loud hum through the speakers


The hum you hear from the speakers and from the unit itself originate with 60hz AC power. They may not actually be related. Sometimes a transformer will hum slightly and unnoticeably. That you're getting a loud speaker hum says there is an electrical leak or a grounding issue somewhere.

Do all sources produce the hum or, say, just the phono? How about on headphones? Try rotating the AC plug. In those days they weren't keyed with one large blade as they are now.

Dell 3300mp Projector Loud Noise


Judging by the mains hum noise and now shaking it sounds as if a motorized component has broken.
Humming could have been the initial jam, then shaking the damaged part attempting to rotate.
Maybe check your cooling fan blades?

Noisy


usually a noisy machine means either the main bearings have gone or the motor has got damaged/worn in some way. to check the main bearings try lifting the drum with the hand from inside or rotate the drum with the hand to see if the rumble can be felt. i cannot think what else would cause a loud humming though.
