Can not set-up surround speakers through avr unit or through the rc-8000 remote. Will not scroll in the speaker set-up menu to identify the surround speakers. Will identify the front, center and sub. Trying to set-up 5.1 home theater speakers through the 4802. Front, center and sub speakers are working, but do not get sound through the 2 rear surrounds. Do not know how to get the surrounds to function/turn-on. AVR is used recently bought through ebay that looks to be in excellent condition. other functions on rc-8000 remote work.

Hi and welcome to FixYa,

Initially, have you tried a full / hard RESET of the Denon AVR-4802? Doing so would allow you to start clean/fresh reverting to factory defaults and remove any glitches, errors in settings, configuration including memories, presets and user preferences. If have not been tried:

• switch OFF the AVR-4802 and unplug from the wall outlet;
• press and hold the DIRECT buttons and stereo button;
• without releasing the buttons, plug the unit back into the wall outlet;
• release the buttons only when the display is blinking.

• consider a DIY (do-it-yourself) repair if and only if very familiar with electronic components & circuitry, use of a DVM/VOM, a soldering iron/station and safe working practices with electrically powered devices. Access to a Service Manual or at the very least, a schematic diagram would be a necessity;
• should you be uncomfortable with a DIY, perhaps your best bet would then be to seek the services of an authorized Hitachi Service Center or a qualified professional.
