Question about Denon AVR-2105 Receiver
I accidentally short the speaker cable when the receiver are turning on. There is a flash and some smoke as well. Now when I turn it on it will automatically turn off after a few seconds.
Could any one please help me if it is relatively plausible for a DIY repair, I know some about the electronic repair but not much about receiver.

I can help you solve this problem. However you must describe to me which fuse you have replaced. Is it the fuse on the power line or is it a fuse in the speaker line (which I highly doubt). usually this type of amplifier uses two technologies. One is transistors the second is integrated chips. This is in regard to the output stages. I assumed you speaker cables shorted each other while the volume was set at a high level with music playing. Anyway if you are willing I am able to help.

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.
Keep us posted,

So you have no sound on any Inputs? This makes a difference, if it works on some inputs but not others. For a factory reset - turn the unit off by the ON/OFF button (not the standby button) hold in the SPEAkER A & B buttons at the smae time, while pressing them turn the system on by the ON/OFF button, wait about 3 seconds and the unit should reset everything.

Check your speaker wires on zone 2 and look inthe manual for speaker configurations with zone 2. you may have a speaker conflict. If you still have an issue, post a comment with your speaker setup and I'll help some more. Hope this helps
