Bottom line is this. Main cause of electronic component failure is heat. Common sense would dictate that if the equipment is off, it ain't gettin' hot, unless of course there is a fire, but that is a problem for another thread or list. The current surge experienced when equipment is turned on is a normal part of operation. The equipment is designed to be turned off and on or they would not include a switch. In my many years as an electronic technician, I've seen equipment fail that was on, off and even unplugged. Nine times out of ten the failure was caused by heat. The one thing that never changed was the customer's insistence that there couldn't be much wrong with it 'cause it worked fine yesterday. Just a message from Doug...
