If you did not have this &quot;Degaussing&quot; then you would find parts of the picture deformed or a particular colour showing in one corner.</p><p>When you switch off your TV it is not possible to reduce the magnetic field around the tube completely to zero, so this degaussing process eliminates this unwanted magnetic field and subsequently allow you AVANT to function correctly.</p><div style="clear:both;"></div>https://archivedforum.beoworld.org:443/forums/thread/170567.aspxTue, 30 Dec 2008 20:33:29 GMT41a2a90c-3a1e-4bd3-b144-3883695a7f38:170567Dave0https://archivedforum.beoworld.org:443/forums/thread/170567.aspxhttps://archivedforum.beoworld.org:443/forums/commentrss.aspx?SectionID=13&PostID=170567That sound is completely normal! It is the tube switching on and doing it&#39;s thing before it reveals a perfect picture.
