Hi everyone,
I'm gathering data to escalate this issue. Can everyone post your model and firmware version and any notes you think may help isolate the cause. Thanks!
If you can hook up to Ethernet cable you can have internet. I am not close to my router so I used a Fire stick and that works.
And I also am just out of warranty, it’s almost like LG have this issue on a timer.
Greetings to all from Peru
I’m in the UK but I’ve also been experiencing the same issue for a couple of months and it seems to be getting worse. The ‘unknown device is disconnected’ message keeps popping up on my TV. Sometimes it happens multiple times during the same day, other times it won’t appear at all. There doesn’t seem to be a pattern or reason for the message popping up
An engineer actually came out to repair a separate fault with my TV last month as it kept making an annoying clicking noise. At this point the ‘unknown device’ message wasn’t a big problem and I didn’t mention it as I thought it would eventually go away, but it’s just worse since. The engineer changed the main board when he visited so I don’t think that is the reason for the problem. I’ve seen other posters mention that this is a problem related to the WiFi connection. At the moment I’m using an Ethernet cable to connect the internet and have the WiFi turned off but the message is still appearing
I’ve also started to notice some other problems. Every button on remote apart from the power button will randomly stop working for around thirty seconds, and my Netflix app has also started to buffer constantly and is becoming unusable. I’m not sure if these issues are relating to the ‘unknown device’ error or not.
This is my set up at the moment:
HDMI 1 - Xbox One
HDMI 2 - BT TV
HDMI 3 - Nintendo Switch
Apart from the Ethernet cable to my WiFi box and the power cable, nothing else is plugged into the TV
Is it worth contacting LG again and having another engineer come out? The TV’s year warranty is now up, and I don’t want to pay for a repair if it’s a problem with LG’s latest firmware update.
I would tell them that the "fix" that they applied did not work and the problem is back. Especially if that original fix was applied under warranty. No reason for you to have to pay for service/repair on something you originally reported under warranty. Doesn't hurt to try.
LG 55UJ750V (14 months old at time of writing)
software version 05.80.15
LG don't acknowledge it's a known fault. Was offered out of warranty repairment for £250 which is disappointing.
