For about 6 months i could not figure out what was wrong with my home stereo, i tried several times and nothing, i figured the receiver may have quit and had been looking online for new ones. So, today i tried again, one last time, made sure every cord was connected right, tried the radio, still no sound. Somehow i spotted a red dot
inside the headphone jack. First thing i thought was LIGHT BRIGHT. I knew something foreign was in the jack as it was inside about 1/4"and fit perfectly, so i heated up a pin and sunk it into the unknown object. Well my first thought was right. frickin' light bright piece. Kids! I would have thought it had to be metal to go to headphones, nope! The stereo now works great.

Well that was an inventive way to remove it, I never would have thought of that!

you say the plastic was enough conductivity to trip the amplifier .. but not enough conductivity to trip the front panel display?
mine says headphones when the headphones are plugged in.. yours doesnt?

Perhaps there is some kind of mechanical sensor/switch which was depressed by insertion.

Makes sense to me, the plastic just opened the first contact point in the headphone jack.
I have read on the forum that if a Denon AVR develops intermittent speaker operation that a likely cause is accumulation of dust in the headphone jack.
The fix is to insert a headphone plug into the jack several times so the contact surfaces reconnect.

Regards,
Charlie
