I noticed that you are the author of much feedback with the MX5500, do you think this fault may be due to capacitors&nbsp;in the power supply??<div style="clear:both;"></div>https://archivedforum.beoworld.org:443/forums/thread/120543.aspxMon, 02 Jun 2008 11:53:00 GMT41a2a90c-3a1e-4bd3-b144-3883695a7f38:120543nobby0https://archivedforum.beoworld.org:443/forums/thread/120543.aspxhttps://archivedforum.beoworld.org:443/forums/commentrss.aspx?SectionID=42&PostID=120543Is it only on tuner or with both SCARTs too?<br /><div style="clear:both;"></div>https://archivedforum.beoworld.org:443/forums/thread/120525.aspxMon, 02 Jun 2008 10:40:30 GMT41a2a90c-3a1e-4bd3-b144-3883695a7f38:120525maqfet0https://archivedforum.beoworld.org:443/forums/thread/120525.aspxhttps://archivedforum.beoworld.org:443/forums/commentrss.aspx?SectionID=42&PostID=120525<p>Hi Guys, I&#39;ve only just joined today and have read many of the comments.</p><p>I am looking for info regarding this fault.</p><p>The set works fine, within 10-15 minutes of switch on, the sound begins to distort and stays that way. I&#39;ve replaced a couple of electrlytics in the audio amp cct but don&#39;t have much experience with this fault. Any ideas or guidance please? &nbsp;</p><div style="clear:both;"></div>
