There you will find a 3V lithium battery. I would unsolder that, leave it overnight, and then resolder it.</p> <p>If you had to replace your laser 3 times on the CD5500, I would say that your service technician should go back to school - there are certain adjustments which have to be done after replacing the laser - spares are still available, and if you had been on this forum then, your CD5500 would probably still be giving you pleasure.</p> <p>Sony lasers must never be adjusted after installation, but Philips lasers (in this CD5500) most definitely do require aadjustment.</p> <p>Menahem</p><div style="clear:both;"></div>https://archivedforum.beoworld.org:443/forums/thread/248373.aspxSun, 27 Dec 2009 10:36:05 GMT41a2a90c-3a1e-4bd3-b144-3883695a7f38:248373waterprsn0https://archivedforum.beoworld.org:443/forums/thread/248373.aspxhttps://archivedforum.beoworld.org:443/forums/commentrss.aspx?SectionID=20&PostID=248373<p>Several months ago my wife punched in a series of random numbers on my control panel.&nbsp; Now, whenever I turn on my system, it locks on the CD player, which I do not have any more as after replacing 3-lasers, replacement parts are not available here in California.&nbsp; As a result I cannot turn on the receiver or the phonograph; I have tried disconnecting everything and restarting, but it does not work.&nbsp; Can anyone tell me how to reset this and help me get my music back?</p> <p>waterprsn</p><div style="clear:both;"></div>
