The NAD T775/T785 AVRs w/ HDMI 1.3 Thread! - Page 131

First off, my apologies if there is separate thread for the T765 owners...I didn't see one so decided to post here.

I've been reading this thread with considerable interest since purchasing my T765HD last July (with AM100 / VM100 MDC), as I too have been keen on finding a way to resolve the loss of the first few seconds of audio when using digital inputs.

In recent days I've noticed some of you 775/785 owners have found your solution in the 1.34 firmware update. I've already contacted NAD and have been emailed the 1.34 firmware package, which I plan to install this weekend. Since I didn't read about any other T765 owners in this thread who have installed 1.34 and have confirmed resolution of the issue, I thought I'd post my results once I complete the install in the upcoming days, hoping that it may help other T765 owners.

My question to you all, though, is when upgrading firmware on the receiver, is it recommended to disconnect all sources, speaker cables from the back of the receiver before executing the install files? Is there risk of specfic harm in not doing so? I ask only to know how much of my Saturday (or Sunday) I should devote to this, since it's fairly simple for me to get to the RS232 port, but disconnecting the system and getting behind the A/V cabinet is going to be burdensome.

Thanks in advance!

Recently I installed the latest firmware (1.34)

Is it just a matter of?
- no power on AVR.
- remove all cables (speaker, HDMI, etc.)
- open the AVR.
- remove old MDC and assemble the new MDC.
- close the AVR.
- connect PC (rs-232) to AVR.
- switch on power AVR.
- run the firmware update (1.34) for the new modules.
- switch off power.
- connect all cables.
- Enjoy the new features!

I'm using a Dune HD MAX connected to my T785, which then goes to my Samsung D8005 Plasma 51".

I'm seeing odd flickering on the screen, it looks like back in the old days, when tv reception cut off(snow on screen). It's there for about a second and the screen return to the Dune HD MAX menu. Even though it's only a second, it comes VERY frequent!

In the 2 minutes it normally takes me to navigate through and find a show, I'm seeing that "snowy" image 15+ times It's worth noting, that the flickering keeps occuring, even when playing media.

* This does NOT occur with Dune HD connected directly to my TV, ie. it must be the T785 causing the problem.

* Turning on the T785 as the LAST part(tv first, then dune), usually solves the problem

* When above fails, I power cycle the T785 a couple times, that seems to get rid of it.

* I've turned OFF all the HDMI CEC options on the Samsung AND on the T785, to avoid any issues with that.

My T785 has the newest v1.34 firmware, AM200 + VM150 MDC modules installed. I've tried 2 different sets of HDMI cables, to no luck.

It's been to the repairs 2 times now, for various issues(HDMI signal loss, HQ audio dropout). It's really bugging me, as I thought the problem was solved.

Any ideas? Should I return it for repair? Try to convince the dealer to get a new unit?

Any input is much appreciated, I'm lost

EDIT: Managed to capture a video of the issue, see here -> http://www.youtube.com/watch?v=-68T5sdJueU

Best regards
Jim

Someone else here also said the same thing. You could do a factory reset and reupgrade your software to make sure everything looks right. Are you having this problem only with Dune HD (I am not familiar with this product)? Hmm. I am running out of ideas. I live in the US so I deal with 60Hz and 24Hz content, not 50Hz.

So, you get the AM/VM cards, attach them together - they have a single back faceplate. When you remove the old cards after opening the box, you have to make sure you remove some grounding cables carefully. Put them all back once you are done. I guess NAD could have made this easier for end user upgrade.

Has anybody else experienced with their receiver that it wouldn't go loud enough?

I can get to about 105dB at my listening position and the audio completely cuts off for about 5 seconds and then comes back.

I would think that at 100wpc it should be able to go louder that that.
I'm thinking of maybe upgrading to the T-785HD to get 120wpc.

My speakers are:
Ft. Mains - Klipsch K-Horns
Center - Klipsch Heresy
Surrounds - Klipsch Cornwalls
Sub- Klipsch RSW12
All very efficient speakers.
Could something else be wrong?
