If "Digital" sign blink on front panel, it means DSP do no start properly. If DSP do not start, main UC mute audio. Change IC, AT49LV002-70TC (IC 817 ) at DSP board (Denon P/N: 262 3010 006).

Denon AVR-2802 Optical Issue


If you look at page 16 of the user manual it tells you how to assign the devices to the optical connections. Once this is done it should work.
If you don't have the manual just type "denon avr 2802 manual" into Google and it will show a free PDF file of it. On my search it came up first!

Technical Problem on my Denon AVR 2802


How good are you with electronic repairs...? Do it if only you are confident...

The way you describe you problem it seems more like poor solder connections somewhere on the board. Usually these are at the voltage regulators where there can be some heat. Also, look for any connections that appear to be grasiny or have rings and resolder them too.

Alternatively, suggest that you take it to the Denon service center closest to you.

Best of Luck..
