Denon AVR-988 Audio-No Video HDMI

[Andyc63]

I am on my third Denon AVR-988. It seems like the HDMI video circuit is going out each time.

Matrix switch on one HDMI port
PS3 on other HDMI port

HDMI out has audio but no video signal

Any ideas??????????

[impala454]

What TV are you sending it to? is the PS3 set to a resolution your TV cannot display? (i.e. 1080p/24)

[Andyc63]

The Mistubishi Projector. 1080 P

All signals set down to 1080i for bandwidth issues.

I have hooked all TV's to the receiver and no video signal from any source

[hifiguymi]

Also, what is the switcher you are using? Does it happen on both inputs? Whenever I've encountered that problem, it's usually an HDCP issue.

Eric

[Andyc63]

Xantech 4X4 matrix switcher

[hifiguymi]

Do you get the on screen display from the Denon?

Eric

[Andyc63]

Nope

[impala454]

if you go component -> projector do you get a picture?

[Andyc63]

I will have to go to the store again to check that one. all out of component cables. But I should open a HDMI cable storer.

[hifiguymi]

It certainly sounds like the receiver is the source of the problem. It's strange that you've had it happen on more than one. I sell Denon (the four digit receivers, not the three digit, but they are very similar) and have never had that kind of failure rate. Actually I don't think I've had any of the current line up that have had that problem.

Eric

[Andyc63]

That is what the installer said as he shrugged his shoulders.

Any recomnedations on a replacement the Denon AVR-988 will just continue to fail

[impala454]

if you go straight HDMI PS3 -> PJ do you get a picture?

[Andyc63]

Yes. The PS3 direct connect HDMI to any unit works great, just not through the Denon AVR-988

Let me also add the the HDMI output of the Matrix Switch works on any other TV/receiver just not the Denon AVR-988

[Andyc63]

System is made up from:

Central Stack AV Room w/
Denon AVR-988
3 Denon AVR-688
2 Direct TV HD DVR
Sony Blueray Server
400 Disc Changer
4X4 Matrix switcher

Displays
Mitsubishi HC 6000 1080p
3 Mitsubishi LCD 52", 1080p

Does anyone have a reccomendation on a replacement for the AVR 988??????

The receivers that I sell are the ones I have the most experience with and I would recommend both. Since you would like to move away from Denon, which is one of the brands, the other one is Pioneer Elite. The VSX-92THX is a really nice receiver. It is discontinued so they maybe hard to find. Pioneer kept the VSX-94TXH and lowered the price but it's still more than the AVR-988. The closest one to the Denon in price is the VSX-03TXH and those are just becoming available.

Eric

[impala454]

Are you able to try PS3 -> HDMI Switch -> PJ? Also have you tried turning the components on in various orders? I.e. turning on the PJ first, then receiver, then PS3?

I would still suspect this isn't a receiver problem... Especially since you've tried three of the same model and gotten the same result.

[Andyc63]

if I by-pass the receiver the video works fine.

The receivers work great for about 2-4 weeks and POP and no more video.

I am unsure of buying another receiver since they won't accept the last one back.

[Andyc63]

Thanks for the reset code Eric. Just a wild shot but still no video.

What do you think of Onkyo receivers?

[hifiguymi]

What do you think of Onkyo receivers?

That is one line I haven't sold. The couple I listened to a year ago or so were OK. I thought they sounded a little thin but I didn't do a real comparison to another brand. What speakers do you have?

Eric

[Andyc63]

Klipsch in wall, front, side and rear. Projector.

3 JBL sound bars per LCD

I hooked the AVR -688 in place of the 988 and it works fine, but I want something a little better in the theater.

[hifiguymi]

Klipsch speakers are pretty easy to run. You should be able to fine anything in the price range of the AVR-988 that will work. In my experience I'd stay away from Yamaha receivers with Klipsch speakers however. With Yamaha receivers Klipsch speakers will sound really bright. Denon, Marantz, Pioneer Elite all work well with those speakers in my opinion.

Andy,
I couple things to try. Have you looked at the Denon video settings? You said you did a reset, so it may not be set anymore.

Have you tried turning the IP scaler off and on?
Have you tried forcing the resolution to 1080i instead of using Auto?

Have you tried your setup with a non-HD source? The PS3 is 720p/1080p. You can't pass a progressive signal as interlaced with the Denons.

If none of that works, and you're really considering a new receiver, I recommend Marantz or Rotel. They are a really good match with Klipsch speakers.

Does the video signal go out immediately? Does the receiver have a lot of air around it?

My Yamaha overheats which causes both the video and audio signal to drop out.

[Andyc63]

I have tried forcing the resolution to 1080i.

I will look for the IP scaler setting.

We have bypassed the HDMI on the receiver and gone digital optical to get the sound working.

It takes about 2-4 weeks for the video to quit working. I have a cool components multi-fan on top and open on four sides in the rack.

similar

I just had an issue with my 3808 that is similar. I was having issues with the video and audio would not sync (only way I can think to explain it). The output was screwy regardless of the input source, HDMI, Component, and Composite. When I plugged the projector directly into the PS3 everything was fine, so I assumed that my cables were good. I exchanged the 3808 in and got a new one, only to find out it wasn't the AVR. It turned out that it was my HDMI cable from the output of the Denon to the Projector. I would have never guessed that the output could screw up all of the inputs, apparently neither could the tech support guy at Denon. The way that I finally figured it out was that when I disconnected the HDMI cable from the output of the AVR the audio synced up. When I re-attached the cable it all went south again. I changed the cable and so far no more issue.

I hope that you figure out your issue and it turns out to be something easy/cheap.

Andy,

You said you tried forcing the resolution to 1080i, but I'm telling you that you can't. Have you tried your setup with a non-HD source? Just from what I'm reading, it looks like everything you're sending is an HD source. You can't pass a 720p or 1080p progressive signal as interlaced with the Denons. You said that you HAD to do 1080i for bandwidth issues. Try 720p and see if it works. It sounds like that may be your problem with your particular case.

[audioqueso]

Now, another thing to double check if it's that interlace/progressive issue, try feeding the Denon a non-HD source. Set your 1080i, and check again to see if that non-HD source works. It it does, then try the 720p or 1080p setting that I suggested, and see if that works.

Tried DVR input at 480i 720p. audio, no video at any 988 setting.

1080p output has never worked. It just showed digital trash when it was working.

[audioqueso]

So your DVR, even if you set the Denon to 720p, it still didn't work. Is that correct?

Do you have any non-HD source that you can plug it to try?

That is correct.

Got bored and even hooked up an old DVD player both RCA and S-Video and nothing.

[audioqueso]

Well, that sucks. If you're going to replace it, then I still suggest Marantz or Rotel to match your Klipsch. But since you have a bunch of HD-sources, I would say Marantz since they have like 4 HDMI 1.3a inputs, and 2 outputs.

Sorry to cut in here but I am having a similar problem. I just got my 988 and I am trying to run my xbox 360 (component) through the receiver and get it to go from the receiver to my sharp through HDMI but when I put it on the input (DVD) I have no picture from my xbox??? Is there a setting somewhere on the unit that I have to play with to get it to work???




Figured out my problem, dam the owners manual is complicated

[Alex Tang]

Hi, I have a similar problem on a new 988. I am doing research and found this thread. I just can't get video output through HDMI for DVD source only.

I plug in a DVD player to component video 1 and opt 2. Then I go to assign input and assign 1-RCA and Opt 2 to DVD. I cannot get video through HDMI. But then I switch to component between receiver and TV, I can get video.

Then I do further tests.

I keep the connection, than I assign 1-RCA and Opt 2 to HDP source, and I can get picture through both HDMI and component! So, I believe there is nothing wrong with the cable, or connection, or my DVD player. And I assign it to the source correctly.

I also tried switch the cable from 1-RCA to 2-RCA, then assign it to DVD source, same thing, can't get video on HDMI out. But if I assign it to HDP source, I can get video out through HDMI.

To further test, I also try switching cable, and switching DVD player. I also try the i/p scalar to off, to auto, to 720p, to 1080i ... I just can't get video out through HDMI for DVD source, and it is only to DVD source only, how funny.

Does anyone has similar problem and found out a solution? I sent an email to technical support, let's see what they say. It seems I need to take it to service center because FS has it out of stock.

[servicetech]

As a TV repairman I've had some issues with the HDMI ports on the newer Mits sets. It's some sort of weird incompatibility issue causing the problem. Try the receiver on another TV before condemning it completely.
