    My son thought he would do the right thing and put an unshielded speaker on
    top of the TV..........surround sound and all that.

    I now have lots of purple faces. What is the best way to sort this out?

    thanks,paul
     
  2. Hi,


    Wnen you turn TV on with main switch, it goes through degaussing
    automatically. Try to do it few times.
    If this does not help, you will need a degaussing wand.

    Thanks guys,

    I turned it off and left it overnight. All ok now.

    But now I am wondering if there is a way to shield the TV from the speaker
    without going to the expense of buying a dedicated centre speaker?

    Since when has lead stopped magnetic fields??? Didn't in my days at tech...
    Might stop Superman from seeing what's inside your speakers!! ;-)
     
  6. Oddly, I had a TV that was turned off for a week (holidays), came back
    and it needed the degauss.
     
  7. Yes all you need to do is either
    1. Remove the magnet(s) from the speaker
    2. Demagnetise the magnets in the speaker

    Dam, here was me thinking it was a simple as placing left handed
    rhododendron monkey in the SW corner of celebrity in my laundry......

    Does this mean I should buy a shielded speaker, rather than build a Faraday
    cage made out of gold plated chicken wire for my speaker.....

    ** They use a second magnet mounted behind the first - with reverse
    field orientation.

    Yes, silly me! So how do they make shielded speakers then?

    Would a HALBACH orientated magnet array work in a speaker, I wonder...
