Re: Random no sound/black screen flicker
The handshake issue for me disappeared when I switched the sky Q box to 1080 rather than 2160. Also the picture improved on normal HD.
I reset the TV (LG G4) as advised by LG and have had no trouble since. Cancelled the Ultra HD from Sky too.

Just to add to the above, the handshake did improve when 8-bit was set instead of 10-bit on the 4K resolution.

Re: Random no sound/black screen flicker
Just a TV reset to factory fixed it for me, until a TV software update comes along and than another TV reset. I have switched off auto updates for now.
Ultra HD is working fine via Sky.

Re: LG G4: Random no sound/black screen flicker
Bought a new lg g4 sound and picture dropouts on dvd changed hdmi lead for a 8k ,have not seen a recurrence but need to recheck on a dvd but it may have worked , similar on sky box , just wondering if a new cable is req , also on these new lg g4 a1 tvs , if you use a1 to adjust sound it will perfect it but when you switch on next day you lose the setting , a1 does not necessarily set it back as before , waste of time using it if after 2 hours of messing about next day , settings gone , i went through trustpilot using all the major tv brands all show a high level of dissatisfaction , all to quick to get on the market without testing to req level ?, [ ex quality control rtd ]

Re: LG G4: Random no sound/black screen flicker
had to get rid off lg tv in the end it was anything but smart , regarding interference with a dvd player , i had a 8k lead buy chance and changed the lead between the dvd player and the tv , but the tv was useless , sent it back and got a sony bravia , no issues , as 8k leads are backwards compatible you can use them without issues , well worth the extra cost if it saves you hours every day resetting issues . sony very good as hdmi connections have frequency details . no issues anymore with interference with sky , so far .

Re: Random no sound/black screen flicker
I have this problem using a Sky Q box, It works fine with Apple TV box.(LG 4G 83) not with a Sky Q box! The SW is updated on everything.

Reset the TV will fix it (until the next update then repeat). I switch off auto updates so I can install in my own time.

Re: LG G4: Random no sound/black screen flicker
Thankyou MrWinn for taking the time responding to my problem regarding the random Audio/sound dropping out on my LG 4G TV and Sky Q 2TB . I took your advice and did a factory reset on my TV excluding the SW update on the LG TV itself. So far so good, fingers crossed. 🤞 I was wondering when, if ever you update the software on your TV. I don't really want to have to go through a factory reset again, on the TV again. Thankyou again.

It's pain but yes I update SW, but wait until I have time to do the reset.

Re: LG G4: Random no sound/black screen flicker
Don't wish to put a downer on things but for many people the reset does not work.
I have done many and it makes zero difference. I should point out that for me anyway the sound drop outs are increddibly random. I can go weeks with no issues then one weekend i can get 20 in the space of an hour.
Hoping it works for you

Re: LG G4: Random no sound/black screen flicker
I know what you mean. I was going to cancel my Sky subscription this morning. There is no point in paying for something that doesn't work properly, and spoiling your viewing. My Apple TV Box works fine, with my LG 4G TV why can't my SkyQ Box.?

Re: LG G4: Random no sound/black screen flicker
We had the same last weekend when watching a recording from Discovery. Funnily enough it did the same this week when watching the same show recording. We watched some in another room on another LG and the sound did drop once so must be the program not the TV. Nothing else has dropped since the reset.

Re: LG G4: Random no sound/black screen flicker
There's a new firmware available in the UK now - v23.21.51
I've had the TV on for a couple of hours now and not had a single audio dropout at all since updating...
I've got LG repair engineers coming in the next two hours to replace the mainboard in the TV (pre-booked because of the sound issue) and I'm not sure they'll actually need to replace anything now.. seems like it's a firmware issue, and fixed... Touch wood?

Re: LG G4: Random no sound/black screen flicker
Is this for the TV? Did you reset after updating?
thanks
