[QUOTE="BSD Meister, post: 1420315, member: 257388"] Electricity follows the path of least resistance. What appears to make sense often doesn't. It's like water flowing from a leaking roof. I had a leak in my roof and wasn't aware if it until I saw water dripping onto the basement floor near a drain pipe! Sometimes it's obvious, sometimes it isn't. An electrical "spike" typically has a lot of very high frequency components that can work their ways around "common sense" paths...they don't go where you think they would go. The output driver stages of a chip are analog and if destroyed only an end-to-end test or some type of test with a loopback connector would verify it...and you might still get the "no cable connected" message. Internal hardware tests can't detect them because they don't measure output or input on the analog drivers. I understand your preference for hardwired vs. Airport, but hey, the Airport isn't THAT bad. Be thankful it didn't take out your whole system. :D [/QUOTE]
