I wonder if what you guys are experiencing is the safety shutdown that Amir found in testing?

I hear you man, frustrating. I have owned my Onkyo TX-RZ50 exactly 2 and a half years and never experienced anything even remotely like this. I am running a D-Sonic external power amp for all my speakers. So the Onkyo really isn't carrying any of the load all the hard work is done by the external power amp. Now that you mention it I need to research my warranty haha.This has just happened to me a few days ago. My setup is 7.1.4 with KEF speakers all around. The AVR has plenty of air and I wasn't driving it hard..hell I wasn't really even driving it. I was watching something at barely audible levels and I got the Amp Diag warning. I tried the reset procedure on the front panel about 6 times and nothing worked. I rechecked all my wires....they were all fine and the hardware hasn't been touched in 2+ years that I've owned it. I finally got the AVR to reset and of course lost all my settings. What I noticed though was when you go through the speaker audio check during the initial setup (not in Dirac or the speaker level settings, this is just an audio test to make sure all the channels are working). I noticed one channel was audibly lower than the others. I went behind the receiver and checked the wires. They were fine. I power cycled the AVR and got it working again and the audio level of that channel was back to normal. BTW the suspect channel is being driven by the AVR. I have most of the channel being driven by an external McIntosh amp.
I *thought* I had worked whatever it was out, but then I started to watch Godzilla Minus One at "shake the room" levels and as soon as the audio got loud, the receiver shut down. I almost threw it out the window.
It had given me the Amp Diag warning many months ago before this latest round. I have a second RZ50 in another room but I'm only using it in 3.1. That one has not given me any problems but I don't drive it at movie levels at all.
I found a service center about 2 hours drive away, and I still have a few months of warranty left. I think I'll drop it off (I don't want to deal with shipping it) and probably get rid of it afterwards. I love Dirac Live and the feature that it gave me at the price range, but having it die on me days before a family reunion and the night before I had to fly across the country for 10 days...well...I'm just taking it personal at this point.
/rant over
Update:
I had my son test it...it still goes into amp diag mode.
I'm not sure that applies in my situation. My standby light doesn't blink. The AVR just shuts down totally.Does it go into amp diag mode consistently? Maybe it had a short, and then needs to be reset before it gets out of that mode.

How to Reset Onkyo Protect Mode | Techwalla
The Onkyo protection circuit is activated when the sensor in the receiver detects excessive heat or voltage irregularities. Using speakers with the incorrect impedance and running the receiver at excessive volumes for a prolonged period will trigger the protection circuit.www.techwalla.com
This is what I found in a Google search, and cannot vouch for it, but step 3 is interesting if that is needed to trigger some sort of counter to reset.
1) accessories4less has the $999 price for both the "NEW" and "Open Box" RZ50. Guess which one you're getting?I’ve been considering the RZ50 and Denon 4800H. At accessories4less.com I see the RZ50 at $799 and $999 (both listed as new w/3yr warranty, not sure the difference). Onkyo’s website shows a sale at $999 as well. The 4800H is $1699. Dirac Live is included with the Onkyo but adds $349 to the Denon. Is the version of Dirac that’s included with the RZ50 full bandwidth? I don’t see an upgrade or purchase option on the Dirac site. And at more than double the price, is the Denon worth it? I have no problem paying but if I’ll never realize the benefits then why? I’m running Revel M105, the corresponding center, Goldenear in-ceiling speakers and an SVS SB-1000. My listening for music and movies is casual. My old Marantz is currently powering this setup but the early Audyssey is lacking. Better room correction is the goal.
I have Dirac Live full range (not limited to bass) on another system. Just don’t want anything that’s frequency limited but you make a good point on future flexibility if I add another sub to the 4800H.1) accessories4less has the $999 price for both the "NEW" and "Open Box" RZ50. Guess which one you're getting?
2) Dirac Live Bass Management and DLBC is not available for the RZ50 (unlike on the Denon 3800/4800). Bass management is done in the AVR only!
3) 90% of the 4800's functionality can be found in the 3800 for much less.
My advice: wait for the $999 3800 flash sale and pull the trigger! Then purchase Dirac licenses on Black Friday for 30% off!

Pioneer LX805 seems to be the direct equivalent, but have more features like XLR in/out. Price looks better too, at least in my region.if dual sub, then the RZ70 is certainly the value/performance leader in the market at the moment.
That's why I mentioned all 3 siblings - depending on where you are and what discounts are going, one or the other may be cheaper!Pioneer LX805 seems to be the direct equivalent, but have more features like XLR in/out. Price looks better too, at least in my region.
Right. We should treat them as one design with 3 different appearancesThat's why I mentioned all 3 siblings
When you consider the RZ70 includes full bandwidth Dirac, it really makes a good value alternative to the 4800H. The RZ70 is available for $1899 at accessories4less.If looking at the RZ50, the equivalent Denon is the X3800....
If your budget stretches to the X4800, you perhaps should consider the RZ70 as well...
The Onkyo's come with full frequency range Dirac, but only the RZ70 (and LX805 / DRX 8.4), have the ability to optionally add DLBC and run dual subs.
The Denon's have 4 sub capabilities... so if that is in the near future plan, the additional cost of the Denon's+DLBC for multisub is probably worthwhile.
If the plan is single sub, then the RZ50 is a great deal, especially with its built in Dirac licence, and if dual sub, then the RZ70 is certainly the value/performance leader in the market at the moment. (and with the RZ70, even with hard to drive speakers, you are highly unlikely to need external amps... it's a beast)
yep.Right. We should treat them as one design with 3 different appearances![]()
As long as you know that you can only do bass management in the RZ50 and not w/Dirac, then you're fine!Just ordered the RZ50 direct from Onkyo. On sale for $999. Prices went up from retailers yesterday so I decided to get freshest stock possible. Key was realizing that the included Dirac is full bandwidth.
