The NAD T775/T785 AVRs w/ HDMI 1.3 Thread! - Page 135

Probably, but no guarantee how soon afterwards it will be available either. Also consider the card will prob be around $600 assuming similar price as AM200. So unless you think you are getting a good deal on the 787, do you want to spend extra to replace the card so soon after you get it? Of course the new model will probably be alot more too. But you have consider the cost of the 787 and the new card.

I am running the newer firmware 1.38 on my NAD T775HD (upgraded with a VM150). I have had this problem twice before, and it returned for one more time. I was watching Prometheus on Bluray - DTS-HD-MA sound track. About 12 minutes into the movie, the volume on the NAD T775HD started going up (it showed the scale on the OSD too). I lowered it using the remote and it went up again, and on and on and on. Finally, I paused the movie and backed about a minute or so and then the problem went away. I think a couple of people in this thread had this issue. Looks like it is still there lurking in the deep recesses of the firmware.

Hi,
could it be that you have enabled "Audessy Dynamic Volume" ?

No. I have not enabled dynamic volume. Only dynamic eq. Also I can actually see the osd with the master volume level going up. Almost like it thinks someone is actually changing the volume.

Bommai,

Is it possible the remote was sending a spurious volume up code?

Kent

No. I had the remote pointing away from receiver. Also, the problem continued until I paused the Bluray movie. Almost seems to me the stream itself was causing the glitch.

Hi Mike,

I just picked up the T775 off of an open box deal. I am running into the same issue that you are describing here where the front pannel and sound goes out and you have to power cycle it to bring it back. It seems to happen after the receiver is running for a few hours. I have it in a rack that is cooled so I don't think this is overheating related. I check the firmware (holding down both source buttons) and I am at v1.34. Are you at the same firmware version? Is there a firmware out there that seems the most stable so far after this version. Please let me know.

Thanks,

Harry

Hey all, I have another audio dropout problem to share.

I have a T775 with the AM200/VM200 boards. I have had the ‘no audio at the start of tracks’ problem for years but lived with it as, until recently, it’s only been at the start of the video. What I’m seeing more frequently however is the audio dropping out throughout some blu-rays but not all. What I’ve discovered is that on the blu-rays where the audio drops out, the main title is made up of dozens of m2ts files and the audio drops out at the start of the next file during the film. So in reality it’s the same problem ive had all along it just seems worse now as some movie titles will be made up of many files/tracks. The video transition is seamless of course. For movies with a single m2ts, the audio only drops at the start.

I’m way back on 1.28. Can anybody pm me 1.34 or 1.36 please. Ive done the update before and I’m familiar with the procedure.
Cheers.

If you live in the us/Canada you can call Nad support and they will email it to you.

I have a 775 - non-HD- version. No upgrade modules. Well, I took it in to get the fans replaced because of excessive fan noise. The tech then also upgraded the FW from 1.16 to 1.38.

Now, I'm getting audio drop outs from my Oppo BDP-83 and clicking noise from my PS3. This happens from both bitstream and LPCM. I was lucky and had none of these issues before. I was afraid something like this might happen.

Any suggestions, please!

Harry,
I only have a problem with the front display going dark. No problems with sound. I am running MCU v1.22. Not sure if upgrading to the latest firmware would improve anything, since NAD doesn't post release notes with it's firmware updates.

Mike

Hi,
I hope someone can help me. I am having audio-dropouts with m T775 upgraded with AM200 and VM200 modules, running the latest firmware (1.38). I only had the drop outs with my Playstation 3 (old design, HD Master etc. only via PCM) when the video was set to 1080p 60 Hz. I changed it to 1080i and everything is fine. I upgraded my Nad T587 BluRay player with the latest firmware and now I have the same problem: Audio is fine with 1080i, dropouts and sometimes audio delay of about 3-4 seconds when running 1080p 60Hz. With 1080i it runs fine.
I will try new cables, as it seemed to help someone else. I don't really like to change the VM200 to the VM150, as it is a downstep (no video processor) and costs around 500 Euros.
Does someone have an idea what else I could try?
I would like to use an older firmware, as I don't like the sound muted for such a long time when switching inputs. Could someone please send me v1.32? My email adress: mkoepfer at t-online.de

Thnaks in advance,

Magnus

I had a problem with a dark (dead) front display. Sometimes I had weired characters displayed. I took it apart, and found out that there was a bad connection of one of the cables going to the front. Unplugged all the connectors, reinserted them and the problem went away. I don't know why it happened, as I had not moved the receiver.

Thanks bommai,

NAD/Lenbrook sent me the firmware which installed fine, now its all systems go. Outstanding service over the holidays.

Hi all, I upgraded to 1.38 checked all my connections and it seems to be fine. I had it running for hours on Xmas with no issue. I'll keep you all updated in case it comes back. Thanks all,

Harry

Magnus - I have similar problems with my PS3 and Oppo BDP-83. Sending PCM and then manually checking only the PCM boxes on the Audio Settings of the PS3 seems to have helped. As for the Oppo, putting it in Source Direct mode also seems to have helped. Unfortunately, with this, I cannot utilize the upconverting capability of the Oppo.

I'm curious if anyone else has had similar issues with the Oppo 83 or 93 and if they've found a solution. Or, if they are not having problems, then, maybe they can post what firmware version they are using on their NAD.

i just tried different cables (cheap to high-end, different lengths). no success. I bought a Oppo 103 today, same problem. With the source direct it works now, (tested a BlueRay with 29.x Hz, the Oppo outputs now 1080i60). 1080p50 is working, too, so it seems the bandwidth with 1080p60 is too high for my VM200.
The interesteing part is, that PCM stereo makes bigger problems than 5.1 HD Master (which IMHO has a higher bandwidth)

My service technician suggested sending an email to Bob Moran at Lenbrook - blmoran@lenbrook.com. I plan on doing the same giving him a detailed report of the problem. If others are experiencing similar issues, they should also so NAD becomes aware of the issue.

Fellas,

Could someone please supply the latest firmware for the 775 HD2? Ive contacted Nad, but they've said the following...

---

Unfortunately, it is NAD International policy not to distribute or share with our customers any of our service updates, bulletins or service manuals. We have this policy to protect the interest, quality and our clients units. We find it is best to assure that all upgrades are installed and tested by a NAD registered service center and/or distributors (which have the country's appropriate version).

It is policy because it could possibly void the warranty and hardware problems could occur if the upgrade is performed incorrectly.

Please contact your local NAD Dealer or country's NAD distributor for further service assistance with newer software fro the T775HD2.

Can anyone help?

Good idea, I will do that!

About a week ago I dropped the HTR-3 remote for my NAD T775 receiver and it hit the coffee table and then bounced off on to the floor. The case does not seem damaged or cracked, but now the remote does not work. I tried changing the batteries and made sure they are making good contact, but the remote still does not function (keys do not light up...nothing). I can still control the T775 from the front panel controls. Any ideas? How hard is it to open up the remote casing so I can check if there is a loose wire to the circuit board or something?

Hi Folks,

I'm in the same situation as Cye. I just bought a T775HD and the seller tells me it has the following revs;

MCU V1.28
DSP V1.04b
Vid V1.01
UART V1.05

I guess my first question is this; I am an IT Professional and have no reservations about updating the Firmware, but would someone be so kind as to send me a PM for obtaining the latest release?

The next question I have is will the latest release (V1.38?) update the DSP/VID and UArt Code as well?

Thanks much everyone for an excellent post filled with a lot of information. Looking forward to enjoying this AVR!

I saw this card provides "Ethernet Network Connectivity", which I assume means that you can get to the Internet. But the data sheet says "Ethernet Port allows network control of the AV receiver".

So I believe the question I have is this; the Network Port most assuredly can get to the Internet, but does the (latest) software (firmware?) support "Interfacing" with the Internet? Will it support "Internet Radio Streaming"? I'm mostly interested in whether you can browse for available Internet Streaming Stations?

Also, do you have to have the VM150 card to support this or will it work with the VM100. I think I know what the answer to this question will be!

Thanks everyone for an excellent post filled with great information!

I talked to the NAD support in Germany today. It seems the audio drop outs with the VM200 module can't be repaired by a firmware update. They offered me a VM 150 module at a discount, I think I will go that way. It will also solve the problem to switch the frame rates (24/50/60Hz) manually for different sources.
Does the VM150 have the OSD like the VM200 has? Or does it more look like a Commodore 64? The OSD of the VM100 seems to look really ugly...

Mungam,

I had exactly the same issues as you had, but on top of that I needed to be able to send 3D content to my TV. The only option available to me was the VM150 and I haven't looked back since. The VM200 would falter with certain media and I had also suspected that it was high bandwidth issue. I don't have any SD sources, so the upscaling features of the VM200 went unused and as I game I'd rather have as little processing between the source and the monitor as possible anyway.

The menus don't look the same as the lo-res ones on the VM100. They do have a different look to the VM200's though. Maybe if I have time I'll take a screenshot.

You will have to update your firmware, or if your dealer is replacing the cards they will do this for you.

So Xterc, are you also using the VM150x? Any input on the use of the Ethernet Port for Internet Radio Streaming?

I've looked around and doing a VM150/150x upgrade on a T775HD is about $900, but if I got improved Video AND Internet Radio, it might be worth it in the long run.

SSound - I'm pretty sure, at this point, the ethernet port provides no function. Perhaps with future firmware updates, there might be the ability to provide internet radio.

xterc - So the VM150 solved the drop out issues for you? Do you have a PS3 or Oppo? Looks like Mungam runs VM200; I have the original non-HD version (VM100?), and we were experiencing similar drop out issues.

Dylan24,

I had the same card you have (original T775 without upgrades), it is pre VM100 (IMHO it has no name). With 1080p I had audio and video drop outs. It only accepted 1080i if I recall correctly.

I have the the VM150 and the expansion card. I did initially have some issues with the VM150x dropping out, but changing cable length fixed this issue (I was originally using 1ft cables and switched to 3ft). I use the following equipment with the VM150/x: PS3, OPPO-BDP93, nvidia GTX680, UVerse STB & a WiiU. The output devices are a Panasonic VT30 & Klipsch THX Ultra 2's. As I mentioned previously, I have no issues with the VM150, but I had so many issues with the VM200 I was regretting the purchase of my T785. I love the sound of the amp, but I could never recommend the amp to a friend or colleague due to the number of problems I've had with it. It was nice of NAD germany to offer you the VM150 at a reduced rate, I wish I'd been offered something similar because my upgrade to the VM200 seemed like a very expensive mistake.

As far as I can tell the Ethernet port does nothing. I've tried telneting, ftping and httping to it, the services are running on the card with test messages, but nothing more than that.

Did anyone had a problem with a volume knob not working ? it started few mouths ago where it sometimes would work sometimes wont and now it doesn't work at all. I can only adjust volume via remote.
Anyone hat this issue and what would be a reason for it to not work .
