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.

Tv and speakers buzzing noise


If the hum is a low note continuous hum, its at 'mains' frequency. The power cables to the unit (or inside it) are getting too close to the cables that carry sound signals to the center speaker. The mains power naturally hums and if mains wires are near to audio kit wires they pick up this sound and play it through their system/speakers. Check the wires to and from it make sure the connections are good and firm. Seperate these wires by at least one inch from any power cables, use tape to hold them down and away from each other.

My acoustic research hd510 has a loud humming noise


check your audio line in connection, either L or R signal line floating may also cause humming noise. Sub woofer usually very sensitive. If your audio input not connected, do you still hear humming noise? in actual you should not hear such noise, unless volume at max then it is possible to hear little.

Altec Lansing GT5051, I'm hearing a humming noise from the speakers as soon as I turn them on. The humming noise is heard even if speakers are not connected to source.If I try and play music with...


Sounds like a problem in the speakers' internal power supply, maybe a faulty capacitor. Speakers need to be looked at by a technician, or replaced with a new set.

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 humming noise from new hdtv


hello, the speakers are fualty or have a shorted connection if they came with the tv contac your seller and arrange for a replacement imediately dont wait. since they are giving you feedback dont use them they may cuase other fualts in your tv, any component thats cuases hum or noise when pluged into the tv should not be used at all.

one important thing is to have a grounded plug this also may cuase fualts down the line,
if posible get a power line conditioner or ups (uniteruptable power supply)

flat panels are very over protective you dont want the tv to start blinking. since flat panels have built in protection circuts any slight short or fualt may cuase the wide screen to go into circut shutdown mode and this will cost you more if the speakers create a short in your audio circut it may damage your widescreen internal boards and cuase a system shutdown circut (red light flashing no picture)

contac your sellers site let them know your speaker are cuasing a loud hum
and that you will need the speakers replaced these are definitely fualty
if you dont have any coverage or you got the set as is then dont take any chances use other speakers.
if you are electronically inclined you can open these up and find out whats wrong with them internaly it may be a loose connection, since opening up the equipment may void your warantee contac the store first see what they say..
good luck happy holidays
