I am guessing some kind of ESD protection component shorted (if you are
lucky). Removing the part would fix the problem. But if it is a logic
input fried, that chip will have to be replace. Paul is your guy for this
kind of stuff.

I haven't had that happen on an AP, but I've had it happen on SMs. Probably
the problem occurred awhile ago and only got revealed when the AP rebooted.
I opened one of the SMs up thinking there was crud across the pins on the
jack, but no, and no amount of cleaning with alcohol would fix it. I also
seem to remember Paul from PDMNet confirming it's not as simple as something
shorting the pins on the jack. So it's repairable, but probably some
component needs to be replaced.

Subject: [AFMUG] FSK AP thinks default plug is in
I'm pretty sure I've seen this question posted before, but I don't recall
the verdict. We had a power outage last night that outlasted the batteries
at a tower. When the power finally came back on, one AP didn't come back.
Further investigation revealed that it seems to think there is a default
plug in it, but there isn't. I've checked the default plug jack and there
is nothing foreign in it, and the pins all appear normal. I've tried
booting it with an actual default plug in it, and then rebooting with it
out, thinking that perhaps that would reset something, but no dice. Is
there some way to recover the radio when this happens?
