Random no sound/black screen flicker

Just re read and you say you have turned off Deep colour for the HDMI. 

this means you are using 8-bit  can you confirm this is the setting you are using?

Sorry it was TV

I am having same issue with my brand new g4 with sky Q has anyone found a fix yet? 

[MrWinn]

Yes, reset TV.

i had to do it again recently after TV had a new software update.

[Samsimmo]

When you say reset the tv do you mean back to factory settings and start again or just turn off at the mains and reboot? Cheers. 

[MrWinn]

 factory settings unfortunately, bit of a pain if you have to do it after every software update.

I have recently turn Sky Q box back to 1080p and turned on deep colour on the TV and picture drops outs returned. Back to deep colour off and 1080i on the Sky Q box. Seems to fix it. I did reset the TV too and that sorted the sound drop outs.

Hi guys, I have several LG 55OLED C46 TVs., and have had the same black screen drop outs for a second or two on all of them. Iv tried tv factory resets after firmware upgrades and it still happens. The only solution I have found that stops it, while still being able to view UHD 4k content is to turn of Dolby digital sound on the Sky Q box.

This has to be a software issue between LG and Sky, but both seem to blame the other.

Nothing has worked on mine. Only way I can get it to stop doing it for a couple days is to turn off at the mains and then turn back on when I start using it and this will last a couple days before it starts doing it again. So I have resulted in turning the tv and sky off at the mains every night until I can get a proper solution from sky and/or LG. When I contacted both of them they both claimed they had never heard of this issue and I need to contact sky back tonight as they are going to walk me through something to try and have said that if what I do tonight doesn't work then basically nothing can be done. LG have said if I don't get anywhere with sky to contact them and they will send out an engineer to have a look.

Had this been resolved yet?

I stopped into Currys on Friday with a friend of mine as he is getting a new s90d oled and I asked whilst I was there about the issue and the sales tech said he has heard of this issue and says there is no current fix and LG shock hopefully be fixing in a software update. However true this is I cannot be sure.
