Given that the brightness and contrast are fluctuating means the most likely cause is the tube, but it could also be a fault in the flyback blanking circuit.</p><p>You will need to have a B&amp;O service centre look at it to be sure.</p><div style="clear:both;"></div>https://archivedforum.beoworld.org:443/forums/thread/53041.aspxMon, 08 Oct 2007 11:00:01 GMT41a2a90c-3a1e-4bd3-b144-3883695a7f38:53041fish0https://archivedforum.beoworld.org:443/forums/thread/53041.aspxhttps://archivedforum.beoworld.org:443/forums/commentrss.aspx?SectionID=13&PostID=53041<p>hi, </p><p>would be grateful for any advice, have a 28&quot; flatscreen avant which has just started to show thin horizontal lines across the screen, i think the lines are about an inch apart and they go all the way down the screen, sometimes you can hardly see them but other times (against a plain black background for example) they&#39;re very noticeable, i think the brightness/contrast may also be fluctuating when they&#39;re visible - does anybody know what this is likely to be?, e.g tube or power supply etc ?</p><p>thanks in advance </p><p>steve</p><p>&nbsp;</p><div style="clear:both;"></div>
