This sounds like the Capacitor plauge https://en.wikipedia.org/wiki/Capacitor_plague The main caps in a SMPSU are quite highly stressed and fail due to the above. If the power is left on the problem goes unoticed untill the power fails then the PSU will not start up (or blows the fuse or switching transistor) This has happened to me many times, one notable one was a stack of 4 Dell network switches all running fine untill a turn off for maintenance. All 4 switched failed to turn back on. I replaced the caps in the PSU's and all were fine again (and still are after another 5 years) Jeff *Players:* SliMP3,Squeezebox3 x3,Receiver,SqueezeLite-X,PiCorePlayer x3 *Server:* LMS Version: Latest Nightly on Centos 7.5 VM on ESXi 6.5.0U2 on Dell T320 *Plugins:* AutoRescan/BBCiPlayer/PowerSave/PowerSwitchIII/Squeezecloud/Spotty/Player Groups *Remotes:* iPeng9/Orangesqueeze/PC/Jivelite/SqueezeLite-X *Music:* 522GB,1660 albums with 23087 songs by 5204 artists mostly FLACs *Want a webapp ?* See http://forums.slimdevices.com/showthread.php?104305-Webapp-for-LMS ------------------------------------------------------------------------ Jeff07971's Profile: http://forums.slimdevices.com/member.php?userid=49290 View this thread: http://forums.slimdevices.com/showthread.php?t=109831 _______________________________________________ discuss mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/discuss
