My denon 1910 has been clicking and dropping sound for a second then working again.when this happens i notice H.P.on then H.P. off.Also sometimes when i turn it on to play a cd or tuner there is no sound.If i plug a headphone jack in and out i here the same click and then have sound.It seems to flick between H.P. on and H.P. off with no one near. CAN ANYONE HELP. TA. Martin.

If DIGITAL sign on the display blink, it mean the DSP board is defective. probably the DSP itself

SOURCE: reset channels??

Here are the links for the manual. I've lost my remote as well. I can't get my unit to recognize the digital audio input (optical). Very frusturating.

Make sure you have an anteena connected and adjusted

I like when a user is observant and curious. That will help immensely in resolving this problem.

What source(s) are always involved with the problem?

You imply it is observable with output video to the TV - "only when there is movement on my tv screen and it stops in still screen". That sounds like a digital pathway problem of some sort as any data errors would eventually escalate to something audible or visible to you once the hardware and correction algorhythms are exhausted. The clicking inside the receiver could be its efforts to resynchronize with a bad data stream. Hence, I'd like you to isolate the ins and outs that fail all the time and find the probable single source of the problem.

Try this: put a digital source on and select/deselect it for listening or viewing. Does it make the click in that brief time it's 'thinking' before you hear the source? That would be the 'normal' sound. My Pioneer does it once per source switch. Repeated clicking would mean it's struggling.

I'm betting you have an optical or hdmi cable that's flaky or not in tight and straight. Or, if only one extternal source is involved we follow that back.

I had the same problem. You're not doing anything wrong. the thing is you can't (I don't know why but the owner manual says it) have sound going to your tv AND your HT speakers when you're using HDMI. You should try going to input setup, choose hdmi audio out to your TV instead of the speakers, and then run an optical cable from your satellite to your receiver, assigning it to the TV/Cable input.
