sound problem

parm21

hi people
i have a dreambox 7020 which is conected in my room which works perfect, however i also have it showing picture on another tv but get no sound, does anyone know why this could be.

Llew

Could be you have the wrong country system set up on your other TV, maybe PAL B/G. This gives picture but no sound.

Should be PAL I.

will give it ago,
though i get sound from sky box

Tivù

The Sky Boxes are crippled - they don't have the facility to alter the PAL mode, so you can only get PAL I.

Your Dreambox is somewhat more flexible!

The fact that your Sky Box does deliver sound adds weight to Llew's response

How is it connected to the TV with no sound? If you disconnect the TV with sound what happens?

I support Llew's hypothesis perhaps it is the 2nd TV itself that need switching to PAL I, what make is it and where did it come from?

its a sony tv

Could it be that the dreambox is putting out a different sound standard and the TV that is working is capable of auto picture/sound system selection (like a lot of the more modern sets will) and the set which isn't giving any sound is only capable of PAL I?

parm21

how could i check this,

is there away of checking that

Crisbe

The guys that have Dreamboxes can probably tell you how to check if the dreambox is set for a PAL I output or a PAL B/G output. I don't own one myself yet but from the fact that the Dreambox is used all over Europe it must have menu driven output settings. Have you tried looking in the setup menu to see what the sound configuration is? It may well tell you on screen. I have heard of this problem before with a portable set taken to Europe in a caravan and not giving sound when a couple in the next caravan had a more modern set which just auto switched between sound systems and so gave the sound. I have to tell you this is a pure guess on my part, but is the set that is working a lot newer than the set that isn't?

Tivù

Exactly so, I think.

I've a mix of "UK only" older sets plus newer Multi-standard sets and the later ones do make life much easier - not only in terms of not having to worry about PAL sound carriers but also in not having to Transcode SECAM! (As in 5W Analogue).

parm21

right i am so confused its something to do with the tv,
cause i tried another tv and sound was fine.

Tivù

Yes and no.

The TV on which the sound is ok will be a Multi-Standard TV and it matters not what PAL version you feed it, as it will detect it and be happy.

The TV that doesn't appear to work will be one which is not so advanced and requires you to feed it specifically with PAL I.

Your Sky Box can only output PAL I, so both of your TVs will be happy with it.

As regards your Dreambox, just go through your Menus to find the relevant RF Output setting/mode ie PAL I. Select PAL I and all will be well.

Crisbe

The first thing to establish is how old is the TV that is giving the problem? If it is older than about seven or eight years it is fairly unlikely to be multi standard, as the auto switching chips only started to be used in anything less than very expensive TVs at around that time. If it is older than seven or eight years it is most likely to be single standard PAL I and your problem is not the set but the signal standard you are sending to it.

As the manufacturers realised that it was easier to build models of TVs that could be used anywhere, instead of different models for different countries, the multi standard TVs became more or less the norm. So, today, almost all TVs are multi standard. Even a cheap one I bought off Ebay last week does PAL, Secam and NTSC.

If your TV gives sound off of a Sky box then the sound system in the TV is okay and working with PAL I.
Assuming that you are feeding the signal in to the TV in the same way with the Sky box as you are with the Dreambox, using the same cables etc. then the problem is more likely to be the output from the Dreambox.

Your Dreambox is German, therefore I would guess that the default output is PAL B/G. If you haven't set the output to PAL I that is more than likely the problem. Or if you have done a factory reset for some reason the box may well have gone back to the default output standard.

Before you do anything else, make sure the output of the dreambox is set to PAL I, like Tivu said, otherwise you will not get anywhere. Please let us know how you get on with the Dreambox, and remember the old engineer's saying: "When in doubt ". Read the flippin manual!

parm21

i have had alook at system settings and the only options i have are ntsc
pal
multinorm
pal+pal 60

Tivù

Select PAL and see if there is a sub-menu .................

It would be very helpful if a Dreambox owner could help us out here!

Pretty please .................

Edit: No idea what "Multinorm" means - but you could try it, I suppose.

parm21

WISH I KEPT THE dreambox guide now.

Tivù

So no chance to , then!

I imagine if you dip back into the Thread this evening, some kind DM owner will have appeared with some product specific advice

parm21

my tv model is Sony KDFE50A12U

Crisbe

Is that the TV that you can't get the sound on or is that the one that does give the sound?
The Sony model you mention is multi standard and should be able to handle PAL and Secam via the analogue tuner but I don't know if it is only PAL I on a UK model.

You've identified that the problem is with the TV in post #12. Maybe you can answer post #5

parm21

thats the tv that gives no sound

Crisbe

Which method are you using to input the signal. Ie: Scart, HDMI, coax etc.

parm21

i have conected it via scart then i have used normal coax for other tv.
i just dont understand why i dont get sound on my sony tv yet sound works fine on other tvs

Crisbe

Have you tried it with coax instead of the scart? I am just wondering if the scart in the Sony needs to see a switching voltage (I think it is on pin 8 in a scart connection, although it is so long since I did any TV repairs for myself that I am not certain) and the Dreambox isn't putting out one. I know the Sky box puts out a switching voltage if it is set up to do it, which will make some TVs switch to the scart input when a voltage appears on it, but I don't know about the Dreambox or indeed the Sony.
It seems strange that you get a picture via the scart but no sound. Without knowing either unit it is difficult to help.
Do you have to select the scart input via the remote control?
Has the TV got more than one scart and if so are you in the correct one?
Are you using exactly the same cable and input when you connect the sky box as you are when you connect the Dreambox? If you are, try selecting that scart on the TV via the remote while it is showing the picture but no sound. It could be that the scart is not fully "open" without being selected either manually or by a switching voltage.
The only way really is to slowly eliminate one thing at a time. Sorry I can't be any more help. I have tried to tell you all the things I would do if I was in the same situation. I would still make sure that the Dreanbox is giving PAL I output though just to be sure.
