Sound but no picture.

[MarcR]

Hello, can anyone help/offer any advice on this problem?

I have an LG 55” Led TV, model No: 55LB730V 

The problem started a little over a year ago when I had Virgin TV at the time, basically I lose the picture but still have sound.

Now, this is where it gets interesting, this only tends to happen on an external app like Netflix. It also happened on the Netflix channel on Virgin and the app on the Fire Stick.

It sometimes happened on the normal TV channels with Virgin, but this is not that common.

In April this year I switched to SKY TV, all seemed ok but then we started to watch 24 on Disney+ a week or so ago and it did it again (we’ve watched Disney for a while and it didn’t go off).

This time it wasn’t random, it happened when there would have been adverts played, i.e. when the time comes up with the 3-4 screens then skips forward a few mins (24 fans will know what I mean).

It’s the same if we put Disney on SKY or the Fire Stick. The normal tv channels with SKY seem to be ok, again it only seems to be an app when it goes off.

I’ve tried swapping the HDMI cables around and only using 1 at a time, none of which worked.

Any help would be greatly received.

Thanks in advance.
