Vero 4k+ LGOled65E9PLA HDMI/Arc and CEC disconnects

Good afternoon all,

About 2 weeks ago I bought a new LG Oled65E9PLA and everything was working fine until yesterday evening. Whilst playing Playstation suddenly the surround sound dropped out. After some investigation I found out that the vero was responsible for the HDMI/Arc not working properly anymore. Also the LG’s Magic remote stopped working on the vero (CEC). After restarting the vero everything was working again until it happened again some time later. I changed the HDMI cable to my receiver and as well to the vero but the problem remains and now it keeps happening every hour or so.

I found on the forum today that it’s probably CEC related and that more people (with LG Oleds) experience the same problem but because my setup was running fine the first 2 weeks I would like to know what triggers this behaviour. I restarted the Vero two times before enabling debug. Then started the Vero with debug running around 13:40 pm. The problem happened again around 14:10 pm but for me being a noob and all I do not now what to look for in the logs. I hope somebody can help me out here.

My logs are here:
https://paste.osmc.tv/ruhufivumo

My setup is:
PS4 to HDMI1 LG
Onkyo TX-NR709 to HDMI2/ARC LG
Vero 4k + to HDMI 3 LG
Set-Top box/OTT to HDMI4 LG

All working with CEC/Magic remote
The Onkyo does not support 4K so that is the reason everything is hooked up to the TV’s HDMI.

I would like to keep the hdmi/arc working because it supports 7.1 Dolby True HD instead of the optical out which only supports 5.1 channel.

Thanks in advance!

Well you would look for CEC messages, if I check at 14:10 I found below summary. It looks like quite some communication that seems to come to no agreement. Not a CEC expert, maybe someone else sees something.

Thanks for the reply. I did get as far as the CEC messages in the log but I have no clue of what they mean so let’s hope someone does. In the meantime I enabled HDMI HPD lock in the settings which hopefully resolves the issue. Still I would like to know what’s the cause.

I am having problems with my LG49UM7400pla similar thing but when it happens it occurs every 30 to 40 secs! I have posted a log, hope someone can decipher it, only way to stop it is to disable CEC adaptor and reboot.

CEC can be very finicky, especially with LG.
You can try a few different things as work arounds but you may want to try disabling the CEC features in the Vero all together and test that out

Thanks but for now it seems that the HDMI HPD Lock is actually working for I had no more ARC dropouts since enabling it. Will see how it goes. Would not like to lose the CEC function of the Vero.

I’ve never tried this HPD Lock.
Can this be toggled in a setting or do you need to modify something?

Should be
Settings > System > Display > Lock HDMI HPD
I assume you have expert level enabled?

Huh… sure enough there it is.
Didn’t know anything about it and the description about what it does seems to be unrelated so never thought to mess with it.
I’ll have to play around with it.

Wow, enabling that option made it impossible to chang emy HDMI input.
If I changed my input to something other than the Vero, it would switch back to the Vero within 5 seconds.
I had to ubplug the HDMI cable from the bac of my Vero to get my TV on to another input.

Yes it looks like this setting does some strange things indeed. I don’t know what kind of television you’ve got but on my LG, with the HPD lock enabled the Vero will show up on all devices. I mean, if I go to Device Connector on my TV and scroll through all the devices I can connect to, the Vero is connected as Set-Topbox/OTT, Bluray/DVDplayer, Home Theater, Game Console and as Other Box.

But it works :grinning:

I have an LG C8.
That setting made it so I couldn’t use any toher HDMI nput essentially so I disabled it.
Glad it works for you though!

I too have an LG C8. I have disabled CEC from Vero many weeks ago, but it still messes with the TV CEC. I only use CEC between LG TV and Yamaha amplifier.

But in many cases the CEC is not working unless I unplug the HDMI cable or power cable from Vero. When I do that, the amplifier somehow releases the inputs, activates TV input again and then CEC is back.
