No Sound from NC+ Multibox Decoder Connected to Panasonic TX 50CX680E TV via HDMI

I don't have this cable; /

I don't want to worry you, but this problem also occurs with others. See what I found on the NC + forum: "Hello; I have a problem with the Sagemcom DSIW74 decoder. Namely, after connecting to the Panasonic TX50CX670E TV set via the HDMI cable, there is no voice in the TV. The cable is good (I connected other equipment and it works), HDMI inputs on the TV also work flawless. TV updates are correct, TV settings and nc + decoder are also correct and ... nothing. I tried to change the HDMI inputs and to no avail. The TV is new and was inspected by a Panasonic service representative. SERVICE OK. ATTEMPTED TO MATCH THE TV SETTINGS TO THE "NC +" TV DECODER, SOUND RECEPTION IS NOT RECEIVED, PROBLEM LIES IN THE MISMATCHED DECODER STREAM. " It turns out that this decoder does not like the new Panasonic tv. Paranoia. If this is confirmed, all you have to do is replace the decoder with a different model.

This is not good news, but there is little progress. It's good to know someone has a similar problem. So, however, the decoder is to blame, now I'm curious if they will accept my complaint and replace the decoder for an older model, because it follows that my TV is not overwhelmed by the current one.

Check this out: Link . This, however, indicates a problem with the TV and the Panasonic service blames NC +.

This link does not explain much. Half of them are busting who said what; /

It does not explain, but the problem also occurs on the older decoder. Write in PM to that questioner if he has solved his problem.

In my opinion - replacing the decoder with a completely different model - there are cases when the devices "do not like" each other.

You can also try to change the tv software - on the manufacturer's website it should be - if it is newer than on tv - change it.

Hello, I have the same problem (TV and set-top box). Has the Lord found a solution?
greetings

Hello to all Panasonic TX50CX670E and newer TV users, probably too. I am a user of this tv model from today and I had the same problem that I did not have sound from the nc + decoder, there was only an image. I combined all the ways possible at home, as my colleagues tried above. Finally I searched the internet and found some information in old decoders he quotes: "THE PROBLEM LIES IN THE MISMATCHED STREAM FROM THE DECODER"
I think I have all the decoders, from the number + to the new nc +, all I tested except the latest black and white with a hard disk, I also tested its smaller predecessor and there was only a picture without sound. I decided that I would go to nc + and replace the old decoder with a 500gb hard disk with the digit + logo (terribly loud at night) for a new white and black nc + also with a 500gb hard disk (quiet as a poppy seed). For the exchange I paid PLN 79 one-time fee + PLN 10 for the subscription every month for renting the set-top box. Please, your new decoder after updating (I will not risk it because I did not know it will work) SOUND WORKS with the picture, so the problem was in older decoders. Greetings to everyone and I hope that I helped those who bought this tv model and they are going to buy it or a newer model

So, as I already indicated in December:

I had a similar problem. For me, it was helpful to change the setting in the TV menu / HDMI input configuration from mode2 to mode1 for the HDMI socket to which the nc decoder was connected. Maybe it will also help you.

Why is there no sound via HDMI?
If after connecting the TV to the set-top box with the HDMI cable, you can see the picture but no sound can be heard, most likely the set-top box is working in the DVI mode. To switch the decoder into HDMI mode, press the "Change resolution" button and hold it for about 5 seconds.

Press Menu on the TV remote control, and then Configuration -> 'HDMI HDR settings', change from Dynamic to Static or Off, and then (still in the Configuration menu) go to' Automatic. setting HDMI 'and select Mode 1.
