I have a 42 inch Hitachi plasma tv that is making a very loud static noice coming from the internal speakers. It stays at a contstant very loud volume unless I completly mute the tv or turn the volum


Based on what you have tried if a buzz or loud static via the speakers you have something wrong in the audio output circuit of the set--problem here is that circuit may be part of the Main board that processes all signal---a look inside---following the speaker leads back would lead you to that board.

A simple thing to do to narrow it a little (you may have done this) is with sound all the way off put your ear to the internal speaker--hear anything at all like a deep hum?

Depending on age of set and cost of the board likely bad it may or may not be a do it yourself repair.

When my KEF home theatre subwoofer is maxing out on bass, it often makes a loud popping noise. Should I be making some adjustments to reverb, volume, or something else?


Hi,
Yes you should make adjustments.KEF makes very good products, however if you don't handle this you will have to replace or service it.
1 If the woofer is very close to you, relocate it further away. The reason being is that the lower the frequency the larger the wave form. The lowest waveforms will become louder.
2 Adjust the high frequency cut off to be at 80Hz. This should eliminate boom. Higher Sub frequency tend to muddy the sound.
3 The sub should have a subtle effect in music. So the relationship between it and the speakers it augments the sound of should be seamless.
4 If you are playing Rap or Reggie music and you like to play it loud. Add another sub into the system and locate it NEXT TO the KEF Sub. In this fashion the two subs will reinforce each other's energy. They will "couple" thus multiplying their energy considerably.
Hope this helps,
Best Regards,
Mark

Loud buzzing from Kef PSW1000 Subwoofer


yes. A good idea. Kill power to the sub, then unplug and remove everything from the sub. go ahead and plug it in again and check for buzzzz.
That is test one. if you have buzz still, its the sub assembly. bad luck, but not impossible. If the buzz is gone its one of the signals to the sub. They can produce a buzzz without any signal coming from your stereo equipment. Replace the feed line, enjoy! BTW...Kef sure does sound clean. good choice.

Blown kef q55.2 tweeter, is replacement possible?


The tweater on my Q55.2 blew as well. I went into a shop in NYC and they tried to charge me $225 for a new tweater, so I took it home and called up Kef. They sent me out a new tweater for $35 and instructions on how to solder it in.
It took all of 10 mins to replace and they are working fine. I've never soldered anything before and it was simple.
Cheers
Martin

I have a kef Kit100. My subwoofer is making a loud buzzing noise, what do I do?


You might have a bunch of bees living inside the sub?
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.
