Earlier&nbsp;units had an underated rectifier, later ones seem to have had that problem corrected.</p> <p>This may solve all of your problems so start there. </p> <p>If still not well&nbsp;check for integrity of transistors on the touch switches. </p> <p>I struggled on a similar problem for a while until I discovered that the one &quot;master switch&quot; transistor was&nbsp; (which turns on the whole until) was leaking.</p> <p>After all this you should also replace all lightbulbs with exact replacements, but don&#39;t worry about this until you get everything working.</p> <p>Derek</p><div style="clear:both;"></div>https://archivedforum.beoworld.org:443/forums/thread/347017.aspxMon, 21 Nov 2011 16:36:29 GMT41a2a90c-3a1e-4bd3-b144-3883695a7f38:347017Dillen0https://archivedforum.beoworld.org:443/forums/thread/347017.aspxhttps://archivedforum.beoworld.org:443/forums/commentrss.aspx?SectionID=42&PostID=347017<p>Welcome to Beoworld !</p> <p>Replace capacitors (a kit exists for this) and the board mounted rectifier.<br />I can supply the parts if you need.</p> <p>Martin</p><div style="clear:both;"></div>https://archivedforum.beoworld.org:443/forums/thread/347007.aspxMon, 21 Nov 2011 14:52:06 GMT41a2a90c-3a1e-4bd3-b144-3883695a7f38:347007Bowman0https://archivedforum.beoworld.org:443/forums/thread/347007.aspxhttps://archivedforum.beoworld.org:443/forums/commentrss.aspx?SectionID=42&PostID=347007<p>Hi everyone,</p> <p>Picked up a 1900 in a boot sale for &pound;5, but there is a small problem with the touch switches. After the unit has warmed up, maybe 10-15 minutes, whatever channel is selected will automatically reset to FM3 within a second.&nbsp;</p> <p>I asume this is a well known fault and wonder if someone knows what component is likely to be the culprit?</p> <p>Opened up the unit but could not see any visible mechanical fault.</p> <p>&nbsp;</p> <p>&nbsp;</p><div style="clear:both;"></div>
