pics might help..
so you're saying that you were inserting a 1/4" stereo phones plug into the "Headphones" jack/port on the back of your P800 and while you were inserting it, it touched the powersupply jack/port or plug while it was live?
essentially running 9V straight into your headphones jack?
I suspect you didnt have power hooked up to the P800.. that the supply plug was off of it and it touched the headphones jack while inserting it.. is this the scenario?
There is no "fuse" I know of inside.. but you may have fried open a diode or transistor inside.. or worse.
