I have a Sony DVD player connected to my Denon 2802 via digital coaxial, and a Sky+ decoder via optical and for ages it has been fine. Last night however, the amp stopped allowing me to change input source via the remote, and stayed stuck on "VCR 1" which is the Sky+ input. (when I say it won't let me change inputs, I mean via the little yellow buttons on the remote). Other functions of the remote still work, say volume, on/off etc. I can change the input via the amp itself, by turning the dial, but it also only seems to recognise one input at a time, i.e. I needed this morning to unplug the optical cable to get it to pick up the coaxial to the DVD player?! Does anyone know how to do a factory reset on the Denon 2802? Any suggestions? Duff remote or something more sinister? Cheers all. P.S. Immediately before this problem, I had a Playstation 2 connected to the amp via the self same optical cable as to the Sky+ box (just switched it over) - could this have caused some issue? Thanks all!
