The "Official" TX-NR708 Owners Thread - Page 54

I've had a Onkyo TX-NR708 for a couple years. I ran Audyssey successfully when I first got the receiver. However, I just bought a completely new set of speakers (JBL ES series) and I'm having trouble re-running the Audyssey set-up. My first few attempts failed with Audyssey failing to detect a speaker--but it was not always the same speaker. Sometimes it failed on the FL, sometimes center, sometimes FR.

So I did a full reset on the receiver. Now, when I run Audyssey, only a single chirp will sound for FL (rather than the usual series of chirps), and the system goes silent. Then, a few seconds later, I get the speaker detect error screen. This happens every single time now. I cannot get last that first, single chirp.

I'm getting sound just fine from all speakers, and the test tones in manual set-up play just fine.

I went ahead and ordered a new mic from Onkyo. Interestingly, although I ordered the mic for this specific model, the new mic is black in color (the one the came with my receiver was silver).

However, as I feared, I get the exact same issue--Audyssey quits after a single "chirp" in the left front speaker, and then goes to a speaker detect error screen.

Anyone have any ideas for troubleshooting this?

If it was you'd likely has odd readings with other speakers, not the same one all the time. At this point you have 2 options: flash/update the receiver's firmware, or send it in for service/repair. Since service/repair will likely involve flashing the firmware again, you might as well give it a try at home. WARNING: flashing or updating the firmware is not a difficult task, but you will lose any/all settings on your receiver and will need to perform a complete setup. Write down any unique settings you have before updating the firmware. After you update the firmware, run Audyssey and see if that solved the problem. If it didn't you'll need to send it in for service.
Good Luck!

Owned 708 for almost 30months now, but just yesterday, 708 just won't start and standby is flashing red light. I read the manual and it says its protection circuit is activated. I searched the problem on the net, and it's probably due to short circuit. And there's a burnt smell on the upper right side near the volume knob and the upper corner near the ethernet terminal.

I can't say its because of old age hehehe. But i think its because of my improper care for the past two days. I just can't figure what caused it... is it because i tried to connect/disconnect HDMI and RCA cables while its off but its power cable still connected to power outlet, or is it because I reduced 708's space from approx. 10inches height clearance to approx 3 inches and played 7 hours and 10 hours for two consecutive days respectively. The room is airconditioned but aircon unit is on the opposite side of the wall about 27ft away. And I also connected my 708 to my newly arrived emotiva xpa3 (this was the reason i changed the height clearance... to accomodate the emotiva). I don't believe the emotiva caused it either.

I like onkyo. 708 is my 2nd. 503 is my 1st and still ok. Now, I am already having second thoughts if I want to get 818 or give other Brands a chance due to what happened.

Can anyone enlighten me on this problem? What really is the reason it bogged down? I believe this can be repaired, but is it worth it? and how much?

Thanks.

I already tried it thrice in a span of 2 days. But still it activates it's protection circuit. I also tried pressing all the buttons in the front panel nothing happens except for the zone 2 button... "ZONE 2 in green color" appeared on the display then returned to protection circuit after 2 seconds.

So far I am as pleased as I can get. The salesman offered my an 808 for $100 more but I didn't think I needed any of the extra features (20 more watts, Zone 3, etc...)the 808 offered.
