Even a small move might make the difference - if you don&#39;t have them both fixed to the wall or something, it might be worth it to experiment a little.</p><div style="clear:both;"></div>https://archivedforum.beoworld.org:443/forums/thread/250203.aspxTue, 05 Jan 2010 02:07:51 GMT41a2a90c-3a1e-4bd3-b144-3883695a7f38:250203Bowmanconsult0https://archivedforum.beoworld.org:443/forums/thread/250203.aspxhttps://archivedforum.beoworld.org:443/forums/commentrss.aspx?SectionID=42&PostID=250203<p>Greetings gang!</p> <p>&nbsp;</p> <p>I was having an issue with my Beo4 remote not working on my Beosound 9000 MKII while my plasma TV was on.</p> <p>&nbsp;</p> <p>I was informed to install a SW 2.21 upgrade chip...which I did, but I&#39;m still having the exact same problem.</p> <p>&nbsp;</p> <p>Do I need to do something special after the chip installation to make the remote work properly?</p> <p>&nbsp;</p> <p>Was this the right chip to install?</p><div style="clear:both;"></div>
