Question about Home Theater Systems

A loud buzz sound when the surround sound unit is powered on.

When the power is cut on on my surround sound system the thing makes a loud buzzing sound while it powers up. It lasts about 20 seconds. After that everything works fine.

    My big screen has also started acting up. Ive ordered parts and am going to fix it next week. Thanks for the warning on running the surround sound. I will hold off on using it until I look at it or have it looked at.

There is most likely a voltage regulation fault, or some filter capacitors that are going defective. It would be best to have this serviced before the parts fail completely and cause some damage.

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.

KEF KIT100 Buzzing


You have a bad set of Audio output IC's for the sub. There is two of them. TDA7293 REPLACE BOTH!!!
There is 4 on one side of board,and 2 on other "also 1 small one" The the two are for the sub,the other 4 are for the main speakers/surround. They sell on Ebay for $6-10 each or a kit of all 6 for $25. I would replace all 6 on your system. To insure that the other's do not go bad after fixing the bad ones.

Buzzing in speakers of cinema surround


i have the same problem. haven't tried the fix yet, but someone recommend connecting the two pronged power cord to an adapter that switches it to a 3 pronged (adds the ground prong). i guess the adapters are less than a dollar and can be bought at most places.

It sounds like a capacitor in the power supply is just about to die. With the power disconnected have a look at the large tin can looking gizmos near the power transformer. There could be a couple of them. Leave the unit switched off for a while before going near them they could still pack a splat. Replace them with the same value and make sure they're connected the right way and it should solve your problem. Whilst in there have a good look for any other smaller capacitors which look as if they're getting rounded at the top. Replace them too. Either that or dig deep and buy a new one.
