Beolab 4 humming problem

I recently bought a pair of Beolab 4 speakers that i connected to my Samsung TV (ue48hu7505) through the 3.5 mm headphone jack. Everything is ok except a really annoying humming sound coming from the speakers. The speakers work just fine plugged to my computer. Unplugging the antenna cable doesn't help. Any advice?

I'm beginning to be desperate.

This is probably noise from the PSU and processor inside the samsung. In a headphone you won't hear this but the sensitive input of active loudspeakers like BL4 can pick it up from a TV headphone output and amplify it.

You need an attenuator in between the TV and the BL's. You can

a) build it yourself: Hissbuster

b) use a headphone volume control, eg this one. Insert between the TV and the BL and set it at 1/4 or half volume (or adjust to taste).

The volume control on your TV will also become more useful instead of already being seriously loud at volume 10.

 

Before you start building check the switch setting underneath the BL4s.

There is one slider position for being attached to PCs and another for other LINE sources.

Thanks alot. I bought that headphone volume control and it worked. Kind of. I now have it set to as low as i can (1/10 maybe), and the humming is nearly gone. I can still hear it when i put my ear close to the speaker. Only problem is that i now have to set the tv volume really loud, but i think i can live with it. It kind of bugs me though that i have this kind of problem, with speakers this expensive.

Are you for real???

Blaiming b&o speakers to be bad and expensive then you have buy a cheap tv without proper line out ?????

 

Um, no. That's not what i was trying to say really. It just bums me that i have a great pair of speakers (yes pretty expensive too) that i am not able to use properly for whatever reason.
