My avr 2106 goes into protect mode in less than 10 sec (immediately after "Receiver" comes up on display during startup). Tried all the normal user resets. If I disconnect the 15 pin connector (cn559) between the input board and cnt unit and restart the receiver will come up completely without going into protect mode but does not output to headphones or speakers. Display works properly with all functions. I'm a hobbiest with some equip and would like a recommendation on possible components to check. Have unit schematics. Thanks.

Normally when this happens it is because the impedence load is too small. This unit requires 8 Ohm speakers. If you connect 4 Ohm speakers, it will work, but work harder and generate excessive heat. If the heat is too much, the unit will enter protect mode and shut down. Once it cools off, it will work again. In your case, if the speakers are the correct impedence, check for crossed wires. If that is the problem, running the unit at higher volume levels should cause it to shutdown sooner.
replace all the electrolytic capacitors in the power supply. i had the
exact same problem with mine and once i replaced the capacitors it
powered up and stayed on and worked perfect. these capacitors tend to fail as they're of poor quality. this fault is very common on denon receivers, especially the later models.
Probably some speaker wires got shorted or the output stages freaked out and the cpu went into protect mode. Normally plugging it out of and in to the wall socket should/could reset it.
First check all wiring at the speaker outputs and on the speakers then if it still wont startup you could try the avr-1500 method with some trial and error pressing of buttons.
avr-1500 reset method: Unplug the unit from the wall, hold down both video select and audio
select at the same time, plug it back in. Keep holding both buttons for
2 secs, unit will reboot. As you have no audio select button on your avr-1100 you might try pressing video select and another key to see if this will reboot it.
It sounds like there is a problem with the differential circuit. The bias I am not sure about, as every unit is different. You should get the service manual to be sure or call Denon and see if they can give you an idea. Good Luck
