The Onkyo TX-NR3007/TX-NR5007 common questions/issues/hints/answers thread - Page 136

Ah right - it's the way the Uverse box works that I didn't follow. Thanks.


Nobody seems to know. But there can't be any doubt that if you filter at 80Hz you will lose the information above that point.


Bear in mind that not every mixer puts stuff as high as 120Hz into the LFE channel, so it will be movie-dependent whether you hear the difference or not. If you just leave it at 120Hz then there will never be any doubt that you will get the full content the mixer intended.

I appreciate that those graphs are showing the results directly from the Oppo, but they also show the importance of the LPF of LFE don't they? Nobody would want stuff as high as 3kHz sent to their sub! How the content gets in there in the first place, I have no idea.

Well, the closest repair center is in Huntington Beach, CA. I think it's cheaper for me to drive from San Diego than to ship the damned thing.

Taking er up Sunday morning. No stereo sucks!!!

They're open on a Sunday?

Indeed! Makes me happy since I have duty today any way.

Hey guys, my 3007 has never given me a moment's trouble until tonight. It's flashing the pink and green, which from what I've read seems to be an overheating HDMI board. Any idea why this is occurring now? The receiver has always felt hot on top, but I have it in a totally open air space. Has the heat just finally caught up with it? I have a bad feeling about this.

Have you checked the HDMI cable and connections beforehand ?

Yes you have the classic symptoms of an overheating, or possibly a heat-damaged, HDMI board. I bet it only happens when the unit has been turned on for some time? (If it happens when the unit is cold then the board is already damaged I am afraid).

Even though your unit is in open air, I would very quickly buy two 4 inch PC fans to use on the back left and right sides of the AVR. Make sure you choose silent running fans. The best way to power the fans is buy a 12 volt 'wall wart' power supply (of at least 1amp rating), then cut plugs off the end of the PC fans, and off the end of the wall wart lead, and connect the wires together, positive (red or white) to positive and negative (black) to negative. You can do it with just tape if you don't want to get the soldering iron out. Don;t worry if the wires are non-standard colour coded - if you get them the wring way around the fan simply won’t work - you won't harm it. Once you've done that, then connect the wall wart to one of those intelligent power strips you can buy from Amazon etc and set it so that the slave sockets are activated when the Amp or screen is turned on. That way the fans will power on and off with the system. If the HDMI board has not suffered terminal damage then this should keep you running.

The problem seems to be that Onkyo used under-specified components in that HDMI board and they eventually get heat-damaged. If you are lucky, and have only just started to see the pink and green flashes, the fans will sort it out for you. You shouldn’t have to do this of course, but until Onkyo solve the problem at their end, it is the only solution. Onkyo may have fixed this in the x009 series, I don't know.

Kind Regards,

Keith

EDIT: as Gurkey says, I assume you have checked all cables for tightness etc and that you haven't recently changed any HDMI cables.

Both Keith and gurkey have good points... however, if you are still in the warranty period I would strongly consider getting it in for repair, be sure to tell them how/when it acts up and push for a new HDMI board! Once it is out of warranty you will be on your own (repair-cost wise).

Good point, Al. But aren't all x007 units out of warranty now? Unless someone bought an extended warranty I guess. Mind you, HST, I haven't had my 5007 for two years yet so that must still be under warranty I guess. You're right - if he is covered then he needs to get them to sort it - the HDMI board replacement isn't cheap.

I guess between us, we've sorted that one! Now then, what's next....

Kind Regards,

Keith

Yes, I bought mine in June of last year so it will still be covered as well...

Once I get mine back and working I need to find a cooling solution.

How about this?

Kind Regards,

Keith

Seriously, see my post a few above this one. Get some quiet 4 inch PC fans. I use Noctua. Best to go for 'fluid dynamic bearings' etc as the fans may not like being operated horizontally otherwise.

Ha! This is what I do:
Link to cabinet venting thread.

Thanks for that link. Some nice ideas there. My gear is in a small closet outside the HT and it so packed with stuff that it is hard to leap it cool. I already have a bathroom type fan sucking hot air out of it, into my hallway. This turns on when the gear comes on. I have PC fans on top of my Onkyo and on top of my power amps. A fair bit of heat comes from the media PC and the 8T RAID arrays that hold all my legacy DVDs too. I would aircon the closet but it is right in the middle of the house and there is no way to vent to the outside. I hate seeing electronics running hotter than they need to so I also have temperature sensors on the key components and a digital thermometer for ambient temperature.

Kind Regards,

Keith

Ok, a laptop cooler looks like about the most reasonable solution. Set it on top and have it suck air up and away from the AVR.

Is it better to turn the AVR off between uses? I know I usually just left mine on and turned off the TV and Cable box. I should probably invest in a Harmony remote.

I always used to leave my gear on permanently on the basis that it was probably better for the gear - switching on and off causes surges that could potentially be harmful. But nowadays, the temperature inside my gear closet can be so high that I turn everything that is not in use off - well to standby really. Despite this, my mac mini, its external drives, the satellite TV box, the Video Processor and the AS-EQ1 are on all the time. But I do set the Onkyo to standby when it is not in use. Even doing nothing it seems to get very hot if you leave it in an operational state. My external amps, OTOH, run almost cold in standby, and certainly much, much cooler than the Onkyo.

Kind Regards,

Keith

In stand by it still passes HDMI to the sub out. So the HDMI board still must be powered up in stand by.

I have my Onkyo, Sat Box, XPA-2, XPA-5 all in one cabinets. In the top I have 3 computer fans that run on a thermo stat and an opening in the bottom of the cabient. Work like a chimeny hot air out top cool air in bottom. So far it has been over a year and no issues.

Alrighty, just got my 5007 back after a week. Not bad for driving it up there and picking it up.

They replaced 2 caps and the HDMI board, go figure. Now I need to hook it up and get some kind of active cooling going.

On a side note, Adam's Electronics in Huntington Beach, CA seem to be a respectable company. At least the regional Onkyo repair center is only a 2 hour drive from me!

I think that's only if RIHD is set to ON (Mine is OFF). This is what the manual says:

"When set to On, regardless of whether the AV receiver is On or on Standby, both audio and video received by an HDMI input will be output from the HDMI output for playback on the TV or other component that's connected to the HDMI output."


Good plan. Heat is definitely a problem for these units. If I switch my cooling fans off, after about half an hour I get the pink/green flashing problem - an indication of issues with the HDMI board.

Kind Regards,

Keith

Any chance they indicated which 2 caps were replaced, it would be good to correlate this with the problem you reported to help someone that is out of warranty...

Cooling, good idea, one I need to address as well, before problems start!

Regarding the HDMI "issues", too bad a person couldn't get this addresses before hand... Sort of a warranty inspection, fix it before it actually fails.

With demonstatable problems like this I would pay a small service fee to have it fixed. The problem is (I guess) is that it lets off the manufacturer from proper support of their product.

So, I got my 5007 all hooked up last night. And I picked up a Cooler Master U3 notebook cooler for $27.99 from Fry's. Yay, they finally price match!

I ran Audussey, but when I broke out my Radio Shack SPL meter the Level Adjust was grayed out and I couldn't calibrate to 75dB. Weird.

Keith,
We are on the exact same page. I never turn off my Outboard Amplifiers and in truth the only reason I put my 3008 on Standby is because I use Martin Logan Electrostatic Speakers. With Panels the less Hours used, the better for longevity. In truth, prior to my 3008, I never turned off my 805, 875, and 3007 even though I was using ML's after the 875.

However, I have not turned off my Amplifiers in over 10 Years with the exception of when I am going to be out of town for an extended period. And that is only because I live in Florida where Lightning is all too common.

Yes - it is definitely the Achille's Heel of these units. I used to believe that Onkyo would have designed it with the heat output in mind, but I don't believe that any more. The components used are clearly not suitable, long term, for the heat that the unit generates, making additional cooling fans a necessity if one wants a decent life expectancy out of their AVR.

Kind Regards,

Keith

I wonder, it seems to me that when I use my 3007 for music only, it doesn't get as hot as when I watch a movie, maybe the HDMI board only 'cooks' when it is called on for video duty?

Either way I will be installing active cooling when the theatre gets up and running once again!

Certainly a lot of similarities there between us, AD. But with one huge, significant exception: you live in sunny Florida and I am here in cold, cold Britain And even then the damn Onkyo still gets hot enough to cook on if you don't use some form of fans!

Incidentally, my Class A stereo amp for my music system has been running, turned on, for about 15 years. Like you, only turned off in exceptional circumstances. Being Class A it needs to get warm before it sounds good and that can take about an hour if the thing has been left to go cold, so I just leave it on all the time. It also doubles as a handy room heater

Keith

I haven't thought of that - I must give it a thrash in Pure Mode and see what happens.


Good Plan

Keith,
It really is a grass is always greener as I have London as one of the Weather Locations on my HTC EVO 3D and often think about how much I would rather live there. It has only been in the past week or 2 that the Temperature has gone below 30C or around 90F. And that is saying nothing of the Heat Index which had been well over 100 Degrees well into October.

Don't get me wrong, currently it is utterly beautiful and it is only going to get better. An unfortunate corollary to this is the return of the Snowbirds who come down in their Cadillac's, Buick's, Vinyl Roofed Crown Victorias, et al and drive a good 20 Miles below the Speed Limit and often pull U-Turns on busy Roads at the drop of a hat.
Cheers,
