Greetings! I just wanted to add some general observations about connectors and electronics devices—I fix this stuff for my “day job”. What I have found over the years is that any connector that is plugged into and out of a jack repeatedly, tugged on etc, WILL break loose the solder connections that hold the jack to the circuit board over time. We see this a lot with power jacks, network jacks, phone jacks, video jacks, and so on. This is a gradual process and the connections can become intermittent or can increase in resistance. Dirty or corroded connections will also increase the resistance of the connection. The result of this is that signals are transmitted to and from the brick with errors and the results can be aggravating. The solution is to make sure the wires inside the jacks are clean and shiny and straight ( just gently rubbing them with a swab and alcohol, or a bit of clean cloth on a stick works pretty well), and if that doesn’t work taking the device apart and resoldering the jack pins. Sometimes you have to replace the jack, but not often. I hope this helps. Gary Gary Cordell
