KEF KIT100 buzzing clicking noise

Hi Axel
After a lightening strike and resultant power surge my KIT100 developed a buzzing / clicking sound on start up which seems to be coming from the Subwoofer box. Read that KEF USA sent you a pdf file that had the fix for the problem. Could you pleaes email me it - Thanks

    Hello -- I have a similar problem.  The subwoofer buzzes then there is a loud "pop".


    Cable mode:  The volume will come on for a second and then a click off with the volume level resetting to the base level of 26.  If I ramp up the volume, sound will eventually return.


    DVD mode:  the volume cuts in and out.


    I have the updated firmware CD from KEF with instructions for installing but this did not help.


    Axel:  Can I get your PDF?  It may help.  If anyone needs the firmware, I suspect that I can provide it along with instructions for installing.


    Thanks

    I have a similar problem. It seems that I will loose volume at level 14 or 15. As long as the volume is above level 16, the system will work fine. Could this also be the firmware upgrade? If so, could you please email me the file and directions? Thank you for your support.

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.

KEF Audio KIT100 System - I have similar buzzing/clicking.


if you have still the problem, I got the solution from Kef USA. It is somewhat involved in taking the unit apart and replacing a resistor and capacitor. With the instructions supplied any electronic technician or TV repair man can do it in less then 1 hour. email me and I forward the instruction in PDF: Xxel_g@mail.coX . Replace the first X with a and last X with m in my email address.
