Hello. I've just joined this website and I'm a bit of a novice when it comes to home theater systems such as av receivers. I'm interested in getting the Onkyo TX-NR646 av receiver but I've read on numerous websites that Onkyo receivers have a lot of technical issues such as HDMI board problems and other hardware failures. I live in Fiji and the only brand the store sells is Onkyo brand receivers which they import from a company in New Zealand. The Onkyo TX-NR646 costs $1650 in Fiji and that's the only cheapest 7.2 channel receiver they have. They also sell Wharfedale speakers which are compatible with the Onkyo receivers. I wanted to know if people living in New Zealand have had any technical issues such as HDMI board problems and hardware failures with their Onkyo TX-NR646 or any other models. If any of you guys have had no problems with the Onkyo receiver for over a year then let me know. I would really appreciate it if you could help me.

I have a TX-NR708, and while I like the receiver's features it has been in for repair twice now. Both times for HDMI issues. And it's been having an occasional HDMI issue the last few months. When it fails again, and I believe it will, I will be buying another brand.

I would like to be able to recommend Onkyo but I just can't. When it's working it's marvelous, but it's just not very reliable.

I've had a number of Onkyo and the older 50X/70X had a few issues but the newer ones I've had no issues

 

I've had a 818 and now a 838 (time to upgrade) and have had no HDMI issues with them

 

Avalon (the distributors in NZ - And in FIJI!) have 2 747's (better than the 646) in stock at the moment going really cheap.. (Around $900)

I have the TX-626 and I tolerate it, I am not in love with it.

 

I used to be able to turn on the Onkyo and right click on a music file and play to / cast to it, after a while I had to press the net button on the remote.

 

Now I have to turn the amp on and work my way to select DLNa then it will work which is a pain.

 

The remote control response is so slow, often takes 5 seconds or more between clicks.

 

Hopefully the newer ones are a bit better.

 

 

 

Cheers

I bought an Onkyo stereo amplifier three years ago which suffered three failures over the time I had it. I've since got rid of it.

I have the 609.  My HDMI board failed too. 

 

Onkyo distributor wouldn't pay for shipping to service it.  The supplied (and shipped!) the new board for free and I had it repaired locally at my expense (cheaper than a courier to Auckland).

 

Where would you have to send one for repairs in Fiji?

I've owned four Onkyos (all flagship or second to the top) over the last nine years. No problems with any of them. Before that I had Yamahas for ten years. Again, no problems with any of them (a few dead pixels on the display of a DSP-A1 that required a $50 fix). I always follow the installation rules carefully, particularly with respect to rear, side and top ventilation space. I also use a USB laptop fan on top with every amp, for a little extra insurance.

 

Onkyos used to get hot. Very hot. But the last few generations have been a lot better. Without carefully following their installation advice things can still go a little pear-shaped, though. Fortunately, Onkyo include a way to track the internal temps of their receivers, so I know my current amp hovers at around 30 degrees C, and spikes up to about 50 degrees after a few hours of heavy use, which I'm quite happy with (steps to access the menu here: http://www.geekzone.co.nz/forums.asp?forumid=34&topicid=108524&page_no=2).

Thanks for your help guys. I really appreciate it. I've found another store that sells the Yamaha RX-V677 7.2ch av receiver. I won't buy any Onkyo receivers because I've read about many people complaining that their receivers have too many hardware failures. I don't want to waste money on unreliable products. The store in Fiji only gives one year warranty and we have no Onkyo customer services available here to repair receivers. Onkyo receivers are way too expensive in Fiji and the TX-NR3030 costs $7000. If I bought 7 speakers and a subwoofer it would cost another $3500. The only problem is that there are very few 8 ohm speakers available which Yamaha receivers need if one uses it to hook up multi channel speakers (7.1 setup ) and they're much more expensive than 6 ohm speakers.

I had an Onkyo, and it developed a fault, and sold it on trade me. I wouldn't buy another. Their speakers though are quite good.

I had seriously been considering buying a TX-RZ800. This thread plus more research into reliability has put me right off! I was mainly interested in the RZ800 due to the weight and power to price ratio. I think I'll look at another brand now.

Yamaha (and Onkyo) will run both 6 and 8 ohm speakers happily.

 

Remember, just because a speaker says '6 ohms' on the back, it doesn't mean that it's going to measure at 6 ohms at all times.

 

The impedance will actually rise well up, then drop below 6 ohms... depending on what you're playing and how loud you're playing it.

 

8 ohms is safe, but a 6 ohms speaker will ask more from an amplifier, and most likely sound great.

 

If you're overly worried about taxing a receiver, put a volume limit on the amp (it's in the menu) and make sure the amp is VERY well ventilated.

I have an Onkyo TX-NR515 which initially had a lot of glitches with an HDMI startup problem, which was fixed by firmware, then had the HDMI board failure after about two years. JB Hi-Fi were good about repairing it under warranty.

I have a TX NR-309.

 

I have had issues with HDMI but corrected this by using better quality HDMI cables.

 

It was playing up on the weekend while on radio but I had been moving it around so I suspect a cable was loose causing the issue.

 

All in all it is a better unit that my Sony MUTEKI 6.2 was, so much louder, clearer and better features than that unit even with a lot smaller speakers.

I have had 4 Onkyo receivers (3 in use currently 608, 828 & 737) and the only one that has been unreliable was the 606, which had the known hdmi failure. At the moment I am considering the replacing the 608 with a 646 but am interested that Avalon have 747s avaliable at a reasonable price. Onkyo are feature rich for the price but something has to give, and that is possibly build quality and maybe reliability.

I would like to reinforce that ventilation is important because they do produce a lot of heat.
