Check on the back of the unit for a switch marked "channel step" or something similar.Usually close to the anntena socket or connection.When you find it switch it to the alternative position.This should solve your problem.

Check the electric outlet to make sure the polarity isn't reversed, which can cause static. Also, check the outlets in the room to make sure they are all grounded which can also produce static. Also, certain cell phones operating a different frequencies can produce a static.

Listen for a relay clicking inside. It you hear it but get no power, it is a problem with the relay. If there is no click, it is probably the power supply.

yes, that should be fine

Have you checked your cables from the turntable? It kind of sounds like you have lost the ground connection on that side, either in the cable or in the turntable itself. Perhaps at the wire going into the cartridge. You might check all these things. Good luck.

I would guess it's the Surround Sound mode button. Various modes in Surround Sound do not use all 5 speakers. Often the button pressed repeatedly changes between the modes. So if you press it again it might restore the sound mode to the one you had. I can't be more specific as you did not give the model number.
You could try the Denon website to see if they have a free PDF of the user manual, if you have lost it. You will need the model number for that though.

Try unplugging it. Another thing is some units have a fuse in the back. Check the fuse with a multimeter for continuity. If meter shows OL then replace the fuse.
