And the first oszillator cap with 6,8nf next to the first power transistor. If the small cap has gone bad, the frequency is to high and the transformer cannot transmit the faster magnetic field.</p><div style="clear:both;"></div>https://archivedforum.beoworld.org:443/forums/thread/298047.aspxSun, 17 Oct 2010 01:31:55 GMT41a2a90c-3a1e-4bd3-b144-3883695a7f38:298047Dillen0https://archivedforum.beoworld.org:443/forums/thread/298047.aspxhttps://archivedforum.beoworld.org:443/forums/commentrss.aspx?SectionID=42&PostID=298047<p>No ideas ?</p> <p>Martin</p><div style="clear:both;"></div>https://archivedforum.beoworld.org:443/forums/thread/297780.aspxThu, 14 Oct 2010 13:33:31 GMT41a2a90c-3a1e-4bd3-b144-3883695a7f38:297780Dillen0https://archivedforum.beoworld.org:443/forums/thread/297780.aspxhttps://archivedforum.beoworld.org:443/forums/commentrss.aspx?SectionID=42&PostID=297780<p>I normally don&#39;t do many TV&#39;s but I do allow the odd family set to slip in occasionally.<br />This time it&#39;s a Beovision LX2802 that has started to buzz.<br />The buzzing is coming from both speakers and are worst (highest volume) when large<br />portions of the screen is white.<br />The set works fine, the picture is sharp and good and the sound is nice as always apart<br />from the buzzing.<br />I read this as a capacitor problem related to the power supply/filtering and the<br />load of having all three beams running at max to&nbsp;produce white. I do have a couple<br />of suspect caps in mind like C5, C10, C12, C13 etc. but I would also like<br />to hear some suggestions from the more experienced TV repairers.<br />Anyone ?</p> <p>Martin</p><div style="clear:both;"></div>
