SB60 started strange bass sound

[Rob K]

<p>Hi there,</p><p><br></p><p>we've had a SB60 do a great job over the last 6ish years (all the time connected to the same Samsung TV using an optical cable). <br></p><p><br></p><p> Recently is started creating a weird intermittent bass throb. I've tried reversing the optical cable and cleaning it, as well as messing about with the TV setting but the bass throb keeps coming back. <br></p><p><br></p><p>Any recommendations to take a look at?</p><p><br></p><p>Rob<br></p><p><br></p>

Hi Rob,

Does the throb occur with the optical cable unplugged?

How long does the throb take to occur? How long does it last?

Is it in time with the audio playing or clearly seperate?

</p><p><br></p><p>no throb with the cable unplugged. it normally takes a couple of minutes for the throb to start, and seems to be linked to the sound, especially music, and sounds a bit like its echoing inside the base.</p><p><br></p><p>as a bonus my daughter wants to choose an emoji for you: <img src="https://www.orbitsound.com/forum/images/smilies/biggrin.png" data-sceditor-emoticon="" alt="" title=""> <img src="https://www.orbitsound.com/forum/images/smilies/heart.png" data-sceditor-emoticon="" alt="" title="">&nbsp;</p><p><br></p><p>Thanks for the help <img src="https://www.orbitsound.com/forum/images/smilies/smile.png" data-sceditor-emoticon="" alt="" title=""> <br></p>

Thanks Rob,

If you change source once the issue starts does the throb stop?

What TV do you have?

Can you try a device on aux, same issue?
