SOURCE: No sound from my brand new speakers

I am assuming you have tried new speakers on used unit on both A & B choices. Have you tried your new speakers with old 2802? If they work OK with old unit, you have problem with amplifier in used unit. Take the used 2802 to a reputable shop and have it thoroughly tested. Perhaps it is just a loose connection.

Needs to be reset or fuse blown. Take to repair shop, cover has to be taken off and fuse replaced. You could fix it yourself but the warranty won't be honored. Do it yourself electronic shop should have a replacement fuse, may have to be soldered in place. Repair shop, should cost around $30.00 to $45.00 to fix, price of fuse $4.00 to $6.00. Your choice.

SOURCE: Shutdown protection? HELP please

All of the Denon recievers I have repaired (over 100) that shut down after a very short time are going into protect mode. The display lights up and after about 10 seconds the display goes out and the standby led blinks red.
I have found that they have one of 3 possible problems and they all require that the reciever be taken apart and fixed at component level. No way to tell what your problem is until it gets put on a bench and troubleshot.

Problem 1. This is the most common problem. One of the front channels shorts out. On the big heat sink the front channels are at each end. It is the front left channel (close to the display) This requires that the output transistors be replaced as well as some driver transistors and some resistors and a capacitor. Lots of work for a blown channel. Denon has put out a bullitin to upgrade the bias transistor and change a couple of resistors to help compensate for this failure. That channel overheats more than any other channel.

Problem 2. There is a resistor that is right next to the preamp board that opens up. It is a 10 ohm 1 watt resistor and when it opens, it causes the unit to go into protect.

Problem 3. The +12 volt regulator fails. It is in the power supply area on a smal heat sink right next to the -12 volt regulator. Generic part number is KIA7812 It also causes the unit to go into protect.

Most decent repair shops can fix these from about $120 up to about $200. Depending on which problem it is and how fast they are at finding the problem. Most charge labor by the hour.
