Onkyo TX-NR807 Official Thread - Page 172

According to the service manual the main power fuse is 10A/125V, the fuses on the "video board" to the right by the capacitors are 4A/125V and the fuses on the vfd board are 3.15A 125V.

You can upload this massive photo you have on imageshack.us.
For some time i'll use it without fuses and other missing parts
It's working without problem for what i need now.

I found transformer with 22V AC, but this is enough

Hope this works.

My HT-RC180 has the common, no sound/no speaker icon, issue. Started happening about a month ago but I have been in and out of the hospital with surgery and didn't feel like messing with it.

I've checked everything, tried a manual reset several times and nothing solves it. There are no service centers in my area so I guess I'm going to have to contact Onkyo tomorrow. Any advice on making this a smooth process when talking to them other than insisting this is a known issue which can be referenced many places including Onkyos forum?

Thanks

None of that matters to them...

Thought as much, was just hoping someone had some pointers that's talked to them recently. At any rate I'll give it a shot tomorrow.

Thanks. I can't see a lot, but it's better than not having anything.

And my 807 just died for the third time in less than 4 months last night. Same issue - No speaker icons, grayed out Network, etc. I noticed 2 nights ago that the usual click clack noise when you switch inputs was significantly muted and then last night, no click clack at all and no sound. Technically my warranty has expired by a month, but as its less than 90 days since the last "repair", I went ahead and called Onkyo Customer Service this morning and confirmed it failed for the 3rd time and they're going to send out a shipping label for me to send the unit back and upon receipt, they'll send a replacement unit back out to me. I didn't have to escalate, etc. this time which was nice.

I'm not happy about having to go 2 weeks with no receiver, but I'm hoping they send me a back an 809 (or anything other than another 807 as this model is clearly a lemon). Its very strange that I had zero issues for 21 months with this unit and then had the same HDMI board failure / no sound issue happen 3 times in the span of 4 months. Makes me wonder if there's something in the actual receiver which is causing the HDMI board to fail and not the HDMI board itself.

Regardless, I'll post once I get the replacement unit.

I have wondered about the same thing as well.

Possibly a bad power supply in the case of mick00016...

I had read that the HDMI board design was bad as in that it heats up too much due bad ventilation & the repeated cycles of heating up too much , then cooling down has caused the soldering points to fracture due to repeated expansions & contractions .
I also believe that is why they went a different Video processor chips in the X09 line as the new chipsets don't use as many watts & are not prone to over heating .

If this is the case (and it sounds quite plausible), then Onkyo is just playing games and wasting time & money (and frustrating 807 owners in the process) by having the bad HDMI boards replaced with essentially the same HDMI boards (or reflowing boards for that matter). That is just going to lead to more failures of the same nature in the future (which does seem to be potentially borne out by a number of posters in this thread).

Well sports fans, turned on the receiver this evening and guess what..........failure #3.First time soldered,second time board replace.I'm not sure there is anything else that can be done,in fact I know nothing else can be done,units are defective.
Unit has had very little use as I have been working quite a few hours including weekends.Never had one of those movie marathon weekends to generate much heat.I believe unit board degrades even in stanby mode as a result of design flaws.
If Onkyo customer service is open tomorrow I will ask for a replace unit.
If they agree and send me an 809 it will be for sale.I will keep you posted.I am through with Onjunko

P.S. When I got the unit back this second time I was going to sell it but couldn't bring myself to do so becuase I knew it would fail again.
I would feel guilty knowing someone busted their butt earning the cash to buy it and then getting a brick.

.

Just bought a couple heat sinks and a 120mm 100cfm fan to cool this toaster down. Surprised this unit has no active cooling. My brother said his onkyo has active cooling and he says he heats his basement with his. Hoping this helps.

It does have a fan with a thermostat...unfortunately, it isn't designed to kick in until you are at a catastrophic temp...

It may be designed as an active heating system. Once the amps get up to operating temp, the fan in front of the unit blows air over the amps which is warmed enough to sufficiently cook the already hot hdmi board in the back. :/

Well count me in on another person with the no sound issue for this receiver. It happened first last Sunday and did a reset that worked. Yesterday turned the system on and no sound, no network and no speaker display reset did not work this time. I purchased mine 2 years 4 months ago so will give Onkyo a call tomorrow to see if they will honor an out of warranty repair. I added 2 pc cooling fans placed on top of the receiver this past November due to the excessive heat being that its in a cabinet that's open to the back but maybe this was to late.

I put a cooler on mine as well, (despite the fact that its on the top shelf of an open air shelving unit) after the first time it failed and it made no difference in longevity.

I probably only ran the unit maybe 10 hours a week after I received it back form ABL (it's in a dedicated theater room), so its not like it was being run 24/7.

My personal opinion is that once the heat causes the receiver to fail for the first time, the damage has already been done, and replacing the HDMI boards is just a temporary fix.

I have used mine even leass than yours!
I have mine 2 years and 4 months too.
I have sent an email to Onkyo and never get any reply neither.
However, I have fixed this problem! NEVER BUY ONKYO PRODUCT ANYMORE period!
I am thinking to have a Yamaha receiver, at least it comes with 4 years warranty. Any good suggestion?

My 807 just did the same thing last week. And lucky me, I got 3 years out of mine...I will never buy an onkyo again...

Are you all talking about tx-nr807? I didn't notice, that this reciever is hot. Mine after few hours playing achieve maybe 40 degrees on top cover. So i ask: what volume level you're using?
In the other hand you didn't touched mine previous reciever TX-SR674E. Few hours playing and top cover near HDMI board was hot like hell, but it worked without a problem.

My TX-NR807 was purchased 2 years ago, but its audio packed up altogether recently.

1. No sound from any source is produced from speakers.
2. Setup -> 7. Hardware Setup -> 5. Network is inactive (greyed out).
3. Setup -> 7. Hardware Setup -> 5. Firmware update is inactive (greyed out).
4. Setup -> 8. Remote Controller Setup is inactive (greyed out).
5. Unit reset ([VCR/DVR] + [ON/STANDBY]) doesn't resolve the issue.

ONKYO customer care has advised to "test the unit after unplugging from power over night and if unsuccessful please contact your nearest ONKYO service point under the following link for support."

What is the feasible workaround?

Just got off the phone with Onkyo and they are sending return authorization form.
Replacement 809 is in the works.
What series numbers are defective as far as the 809 is concerned?
Anyone who got a return authorization,how long did it take to show up in your e-mail?I've been waiting over 1/2 hour and nothing yet.I'd like to get this 807 out the door before I head to work.
I'll keep you posted.

My 807 never ran HOT.Warm yes,hot no.
Unit sits at bottom of my rack with 12" of room from the unit above it.Wide open on all sides.Its located in my basement rec room which is very cool all year long.
Unit is defective,no ifs ands or buts.

Sorry to read about your latest problem. My unit is still functioning correctly after the HDMI board replacement. I'm not confident that will continue.

This will definitely be the only Onkyo product I'll own.

My 807 receiver was purchased from Crutchfield in Dec 2009. I had been able to unplug and re-plug the thing and get it working most of the time until now.

Now it's
no sound,
no network
no firmware update.

The Crutchfield guy was nice enough but gave up referring me to Onkyo. They are closed tonight, guess I'll call them again tomorrow. Although reading this thread makes me pretty saddened.

Where to get return authorization form and how to apply?

After waiting on hold 20 minutes this morning the Onkyo rep suggested I fax my issue description, contact info, S/N & Model # to 201-934-7823

What is the country code for this fax number?

You have to call and speak with an Onkyo representative and have them email you the authorization and return shipping label (which comes from UPS).

However, you probably will need the unit to fail at least 2 or more likely 3 times for the same reason before they'll agree to replace the unit. If its the first time, they'll instruct you to take it to a local repair facility and then the fun begins!!!
