Hi all,
I wanted to share a strange issue I am experiencing with my Denon X2100 avr. I would like to know if anyone else have experienced something similar and if the experts can shed some light into this. (I hope I am not wrong in starting a new thread)
Symptoms:
- The avr will restart continuously whenever I switch it on, within 5 seconds after sound comes through the speakers. This will continue until I power it off using remote.
- The reset happens in such a way that the red light comes on momentarily and immediately it starts blinking green with a loud 'click' noise (restarting). This does not look like overheating or protection circuit activating as described in the troubleshooting section in Denon online manual.
- If I shut it off completely and replug after a few seconds, sometimes it will work fine for a while, before showing the symptoms again in an hour or less.
- The restart can be anticipated if there is a 'click' sound during start up (green light blinking) which is not normal.
- I have removed all the cables except the power cable and still the issue persisted, though after a couple of cold starts it was working.
- This problem started occurring on rare occasions 2 months back, and frequently since last 3-4 weeks when I have plugged in the AVR along with airtel HD box and 22" samsung TV into a belkin surge protector, plugged into a 6 amp point (As per the maths, the total current draw must be less than 6 amp in this setup).
- The avr was also heated up much though it did not seem like restart due to overheat as per the explanation in the manual.
I have done a fair bit of research in various online forums including here and seems to be able to control the issue temporarily. The following are the steps I have tried so far:
1. Checked all speaker wires for continuity using a multimeter - no issues.
2. Measured the resistance of all the speakers using multimeter. I have Boston Acoustics A26 front and A225C center channel which are all rated at 8 ohms. My measurements indicated 7.8 ohm for A225C and 4.6 ohm for A26 which I found confusing. Ain't A26 supposed to show 6-8 ohms if it is having 8 ohm impedance?
3. I had a 16 year old locally made(?) speaker pair (part of a stereo system labelled "T-series") which measured 4.3 ohms in multimeter. I disconnected them although the avr was working fine till now with those connected.
4. I cannot remember if the issue occurred when the AVR had a dedicated 6 amp plug point. Anyway I have now provided a dedicated plug point again and except in one odd occasion, i am not seeing this issue.
5. As an additional precaution, I have set the avr to 6 ohm speaker setting yesterday and also reduced the airtel box volume under user settings (to reduce input load?).
As per my observations, steps 3 and 4 along with reducing airtel box volume settings seem to have helped (also reduced laptop output volume when connected as a source). There are no voltage fluctuations generally in my area, and I use home inverter with regulated mode. There is additionally a GM powerstrip and Sollatek voltage guard always between the mains and my AVR. I have started with 4 speakers and added A225C 4-5 months back. All I can think is somehow the amp load increased when i plugged all the devices into power strip and it started restarting, though cant imagine how this could happen with a 500W AVR!
Sorry for the long thread, but hope someone can shed some light here. I am also curious as to the resistance readings from the BA A26 speakers mentioned above. There were a couple of occasions where audyssey stated that FL is out of phase though this was not the case.
Anyone else facing similar issue can share it here, especially X2100 owners since I could not find much online information on this relatively new device.
