Hi,
The problem is noted by a low frequency erratic oscillation of the woofer causing sound even without input signal. If the sound is too high, the loudspeaker shut down itself.
There is no more problem if I disconnect the B134-B135 feedback connector.
According to your experience, what could be the cause ? Is there something wrong on the woofer or on the electronic part ?
An other question: is it possible to buy the pivoting front plate with plastic hinges ? What would be the price ?
Thanks for your help.
Regards
sounds like you have a broken mfbsensor in the lowunit .
most of the time its just come loose from the glue in the conus . en it gives a rumbeling sound as if thunder in the distance . the servicemanual is downloadable on this site , look onder the link sitemap .
its fixable , somewhere on the site is a manual how to do it , made by the site admin . its a delicate job and if you havo no experience with this sort of things you can buy a spare woofer , or let it repair by the mfb servicepoint .
greets mattie
