Question

No sound on HD channels

Dec 16, 2017 6:43AM PST

Need some help please. I recently upgraded my tv to a Toshiba 40BV702B. I have a separate HD freeview box plugged in with the sound coming through my hi-fi system.

I had this problem before and I can't remember how I rectified it but the sound is not coming through on the channels but OK on all others.

Can anyone help me please. To be honest I only rectified it last time by accident by moving wires and stuff but I can't remember what I did

Most common? TV doesn't pass HD audio.

So the source device is set to send PCM or Stereo (which ever works.) The usual HD Freeview box (no model number in post?) is HDMI so it's not usually a move of the wires but a setting in source or TV back to PCM or Stereo.

Manhattan HD freeview box
Dec 16, 2017 8:20AM PST

Hi, many thanks for your reply. I have one of these https://www.tesco.com/direct/manhattan-plaza-hd-t2-freeview-hd-digital-tv-receiver/320-7521.prd?skuId=320-7521&pageLevel=sku&sc_cmp=ppc*PX+-+DNF+Electrical*PX+-+Shopping+GSC+-+Generic+-+Vision*PRODUCT+GROUP320-7521*&gclid=CjwKCAiApdPRBRAdEiwA84bo3w8XgogAB_deLgQWyGhR-WGCjaD4I3K9BMowkmn0YLkh08N9X7SGvhoCnAAQAvD_BwE&gclsrc=aw.ds&dclid=CIvL9Ln2jtgCFZcg0wodf8wBVw. I have tweaked so much about but nothing, the tv is set to PCM and Stereo. I have tweaked both but still nothing. I have the aerial plugged into the box, an HDMI cable from the box to the tv and also a scart lead from the box to the tv. I was having trouble getting a decent pic on the tv so added a scart and it picked it up better but then it sources different on the tv. At the moment on the tv it has sourced to HDMI1.

I had this problem before, as I mentioned, when I upgraded my other tv and I just can't remember how I rectified it. I am just not very experienced at this sort of stuff and it's driving me mad

That box has a lot of options.

I see so many options that I can't work them all for you. I usually go with HDMI with the box set to PCM and stereo. You already have the TV set so set the box too.

SCART? Isn't that for old sets pre-HDMI and low quality?

I have done it
Dec 16, 2017 9:10AM PST

omg I have done it. Just tinkering in the menu and came across a button for "audio description". No idea what it means but as soon as I pressed it to the on position the sound came on Happy

Another problem I have is the quality of sound. As I use the sound from my hi-fi the quality on through my previous tv was amazing, just like being in the cinema and the bass was wonderful. when plugged into the tv I have now, it's not as good and there isn't as much bass and boom as I like when watching a film. Any idea why please?

Why SCART?
Dec 16, 2017 9:37AM PST

And since there are too many options I can only advise to try all options of connecting. It's odd to see SCART used today. Is there more to the story like the TV is pre-HD? But the model looks to be HD so why not HDMI?

unplugged
Dec 16, 2017 9:39AM PST

Have unplugged the scart and it's fine now. Was just another option to try. It is also connected via hdmi. It's the sound quality I am stumped over now

So if this was mine....

The HDMI would go to the sound bar or receiver first then on to the HDTV.

We have the HDTV and the tuner but not the sound system.
