Fast kein Ton mehr vorne rechts

Hi,

Impossible to say. Surround-Receivera are complicated and not easy to diagnose from a distance.
You say you hear some distorted sound in the speaker. That would indicate the fault is NOT in the output amplifier. When it is defective it will put DC-voltage on the speaker-terminal and the protection-circuit disconnects the speaker.
As this is not the case I would guess the amplifier is OK.
The fault may be in the electronic input-switching or ANYWHERE in the signal-path.
The receiver weights around 25Kg so I would think it's in a league where it would be reasonable to have it serviced

I can help with schematics but you should find someone familiar with electronic circuits to do the actual repair. An oscilloscope will be required if there is a fault in the signal-switching.

hmm, electronic input-switching?

I just know that my speaker is okay since i switched the front left with the front right. the cable itself is also okay since it worked perfectly when i changed. (the one which is not on the broken output)

Finding someone who is familiar with electronics shouldnt be my problem but if he can repair a amplifier.

the distorted sound is like, hmm, if i turn up the volume and you go really! close to the speaker, you can recognize! the sound/melodie/bass from the song which is playing. or the tv. its very very disturbed.

so you dont think it is the output itself?

so you dont think it is the output itself?

Almost always when the output-amplifier is defective and the sound is distorted because of this, the amplifier will put a DC-voltage on the speaker output terminals.
Because this is deadly to the speakers, at least the bass-speaker, all amplifiers have a protection-circuit that constantly monitors the output for DC-voltage. If any is found, the Speaker-relay immediately disconnects the speakers and of course they are silent.
This doesn't happen in your case, so I would expect the amplifier to be OK.
The Speaker-relay itself may be defective; i.e. the contacts doesn't make fully contact. This is also a common fault, at least in older amplifiers. Your's it too new for this problem to appear already, I believe.
The input signal-switching is done with integrated circuits in this Denon. I have seen these switching IC's become defective in many amplifiers, so that's quite common.

When you find someone who will take a look at the receiver I can help with schematic diagrams.

My Speakers are okay. I really know that. Thats 4 sure. Hmm, i looks like now i just got the center and the left front speaker working. I will look if i find someone.
