We have had our Denon AV3300 for several years and it's worked like a charm. Suddenly we have lost all sound. Any suggestions?

Blow some compressed air into the headphone jack, or insert/remove a headphone plug a few times.

That seemed to help for a couple of days but now it's off again. I also had unplugged it for 12 hours as recommended by another site. Tried uplugging again and using the compressed air but it won't come back on. Any other suggestions? Thanks for your help!

Not turning ON and no sound are two different issues. If it's no longer even turning on, I'd pop the top and check for a blown fuse.

Sorry. I meant, still no sound. Unit turns on fine!

Try doing a bunch more of compressed air shots. If still no joy, then check the Owner's manual and reset the microprocessor.

Will do. Already tried a bunch of times but I will do it again. Not sure how to reset and if that will mess up any programming?

Yup ... it will return all settings to their factory defaults, but then again ... your only other option is replacing the AVR.
