Hi, the type of UPS mentioned by Teo Audio is called a "Line Interactive" UPS. Although most have a sine wave output it is always wise to confirm that the UPS being considered has a sine wave output.

Got one of these. Seems quiet enough from my listening position (set on low speed).

I bought a "b" stock denon avr-s920w from gibby's electronics at the end of March to use in a little 3.2 system at work and it just bricked itself. Dropped it off for repairs this morning, we'll see how it goes.
Never had one die on me before.

Good luck. Hope the warranty is still in effect.

On the vast majority of them the HDMI is tied to the daily operation of the unit and if there is a fault in the HDMI, the unit bricks itself. All of the self check circuitry, software, etc, is on the same board as the HDMI, in all of the units I've seen the tech manuals for..

Use non hdmi amplification and separate hdmi switcher if possible.

Boy you lads in Ontario sure have your share of electrical & HDMI issues! I haven't heard anyone in my area that's been plagued with these kind of issues. Is it the grid screwing things up?

I was going to post the exact same thing. My juice here in the desert is primo, but out in Ontario it seems maybe not.

We do have a lot of power issues in this area. Some weather related, we're prone to lightning, and an antiquated grid.
We have frequent power "blinks". Outages short enough that you may have to reset the microwave clock (my Bryston gear just goes "click" and goes back to it's ready state) or the Rogers box.
In addition we have the CAMI auto plant less than three kms. away and a hospital less than a km away.
I think it puts significant strain on the grid but our local utility says everything is just ducky (really didn't expect them to say different).
There is also a possibility that I'm cursed (can't rule it out) by A/V gear. Everything else in the house works fine with no power related issues (Rogers boxes can be "touchy").
I'm not driving the equipment hard, I've added several layers of protection yet they fail.I wish I knew for sure what the hell is happening.
Things I do know for sure, HDMI is a farce. Fragile beyond belief. Onkyo and Denon are the two worst A/V companies on the planet.
Credit where it's due, Marantz did repair my NR 1403 at no cost.
So why use HDMI?
Well there's codecs available only through HDMI, ease of set up and that's the way the manufacturers want you to do it.
99.9% of people that buy an A/V receiver do nothing other than hook up multiple speakers a sub or two and a few HDMI cables.
They don't piss around with "exotic" cables, fans, surge protectors or anything beyond the most basic hook up.
Why mine has repeated failures? A question I can't answer.

The continuing adventures of...
As I mentioned before I got my receiver repaired and added a fan as 'extra' insurance.
Things went along ok until last Wednesday or Thursday.
The TV had repeated "blinks". A momentary flicker lasting just a second. The audio would drop out and the screen would get a sort of static picture. If you weren't watching closely it was easy to miss. Problem was it was happening a lot.
I waited for a while before I checked further into the problem. We had had a series of storms blow through the area so I thought maybe it was weather related. The weather changed but the problem persisted.
I decided to check the cables to make sure they were properly seated. No problem there.
I checked the STB. No problem.
I did unplug the fan, which I had plugged into the outlet on the STB.
Since I was planning to plug the fan in elsewhere, I left it unplugged.
I turned on the TV and no more "blinks".
Perfect,stable picture. The damn fan was causing the problem.
I plugged the fan into an APC surge protector and it isn't causing any more problems, at least for now. :roll:
