Annoying message pops up on my TV
The words “unknown device is disconnected.” keeps popping up on my tv every few minutes or so. It’s been doing it more ever since I updadated my tv and it’s really driving me crazy. Anyone know the solution to this?

Have you identified what connection is causing this error? do you have multiple electronics connected to your TV? If so, try using it with one of them disconnected and every 15 minutes rotate the product that is disconnected. Once identified, ensure its properly connected, try using different ports and / or cables to confirm if its the TV port, the cable or the product its connected to.
If the above does not solve the issue, you can try a factory reset.
If that still does not fix the issue please let us know your model number and the software version you are currently running so it can be escalated.
The only thing attached to my tv is the cable box.
This started up about a month ago. I am trying to stream amazon and it will not connect.
I am thinking that these are related.
my disconnect with amazon started at the same time.

The issue appears to be related to the wifi board in the TV itself. Some individuals experiencing the issue have had that board replaced and a few report success while others do not. Since I use the wifi capability of the TV to watch Netflix and Amazon Prime, the TV is now useless to me as it can't access the wireless network.
I just wanted to give an update on what’s happened since the last time I posted on here. I apologize in advance on the length of this post but I want to go into full detail on what a poor job LG is doing in the concern of resolving the issues with my television. The last six months have been hell regarding LG “repairing” my television. The’ve attempted to repair my television twice within the last six months with both results being the same. The first time they attempted to fix it was in late July everything was fine for a few days but I would soon receive the same notification “Unknown device is disconnected” on my television and my tv would shut down and turn back on by itself. I contacted them again in late August or early September concerning the issue and they said they would send the technician out to attempt to repair it again. The technician arrived two weeks later but was unable to work on the television because LG sent him the exact same part they sent him the last time and he said it was useless, so he drove an hour to my city for nothing. I contacted LG again and told them that I was not happy and that they needed to resolve this problem quickly. They said the part needed to fix my television was unavailable and would not be back in stock until the last week of October, a full month from when I contacted them. I waited a full month for the part to become available. Finally the final week of October came and the technician came back to attempt to fix the television again. Once again, it was fine for a few days and then I would have the exact same issues again. I’ve contacted LG numerous times and asked for a reimbursement but the’ve only given me the runaround and stated that the television needs to be attempted to be fixed three times before reimbursement can be taken into consideration. The final straw came a few days ago. I called the repair company that’s been working on my television and they said that they no longer offered their services to my city because it’s too far for them to drive here now. I contacted LG once again and told them about this and they said they would find another company within my area that specializes in repairing my television. A day after that, I received a text from LG stating that they had set up an appointment with another company to come fix my television. Lo and behold, it was the exact same company that said they didn’t come to my city anymore. I called the repair company just to confirm. They said LG made an error and they would contact LG. LG cancelled my appointment. I spoke with LG a day ago and told them to either reimburse me or that I was going to take legal action. They asked me to be patient and that they were looking for another alternative. They said that there appeared to be no one around me who specializes in repairing my television but that they were making a great attempt to find one.
I’ve never in my life been so displeased and dissatisfied with a company in my entire life and that’s not an exaggeration. I once was a strong supporter of the LG brand and have even recommended their products to family and friends and most of them have purchased their products based on my endorsement. I will no longer purchase a single product from LG ever again for as long as I live and will strongly discourage anyone else from doing so based on the experience I’ve had with them for the past six months and I will most likely be taking them to court as I feel that they will never resolve this issue on their end.
Thanks for your diligence in keeping this forum thread alive. I share your disappointment about LG's inability to come up with a solution. Knowing the steps you've gone through are helpful even though you've not had any success.
In combing the Internet today regarding the issue, a new post was discovered on the CNET.COM forums (https://www.cnet.com/forums/discussions/unknown-device-is-disconnected-lg-tvs-solved/). The word "solved" caught my eye. I've pasted the post below (yeah there's a bit of voodoo in the possible fix ... but the steps are certainly easy to replicate). I plan to give it a try today and I'll post back with the results.

Model: 65UJ750V-ZB
WEB OS TV VERSION: 3.8.0-61106 (dreadlocks2-dunggir)
The 2nd repair company came back and said that they found this forum and this should fix the issue. THIS IS NOT A FIX!! This is a band-aid. A cheap band-aid that doesn't stick well!!!
LG Needs to fix this!!!
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!
-"unknown device disconnected" message along with Wi-Fi disconnection.
-random reboot followed by a few seconds of mute.
The problems sometimes occur very often, say 2-3 message popups per sec, sometimes do not appear for a few months.
Tried factory reset and skipping Wi-Fi setting with no luck.
I strongly recommend LG add a Wi-Fi ON/OFF switch to prevent the buggy Wi-Fi module from being initialized.
I don't care the internet, I don't watch TV, I just want a stable PC monitor.
I get Unknown Device. Then Lan cable disconnected and connected right after.
I get about 1 minute of Netflix before the buffering starts. (takes a long time to watch a movie).
Model (65UJ7700)
LG TV UJ6585 Software Version 05.80.10
My model is (I think) 49SJ800V - ZB and it's running on software 05.80.15.
model # 49UJ6200-UA
software version 05.80.10
This is a UJ6300, version 5.80.10.
I have it connected to Ethernet and HDMI - I don't use its WiFi.
Purchased Nov 2017.
Spring 2018, Wifi not working, and remote sluggish (at best).
When under warranty, replaced Wifi and Main board 1x.
About 2 weeks after replacement, wifi went out again, but I don't use it, so just let it go.
Around Dec 2018, started getting popup of "unknown device disconnected" appearing at random intervals, repeatedly.
Late Dec 2018, started randomly power cycling
Jan 2019, occasionally doesn't recognize HDMI input from xbox when it starts up. Require power cycle of TV while xbox remains on.
Called, and of course, since it's just out of warranty, they can't do anything.
Would gladly replace faulty components myself if I knew what to replace, but sounds like it's a waste of time.
Connections:
Xbox one X: HDMI 3 (HDR on, CEC off)
Chromecast 4k: HDMI 4 (HDR off, CEC on)
Coax antenna IN
Digital Audio OUT.
Very frustrated with LG's lack of service
None of this started happening until after I got this update.
For me, this is an easy "win". Removing a functionality I rarely ever used in order to prevent larger issues.
If you use the internet connection on the TV, could always setup a WiFi access point and use the wired ethernet connection as a workaround.
Glad to hear that!
Could you please teach us how to do that?
Do I have to remove the entire back cover?
It'd be the ultimate means to get rid of this really annoying problem for good.
I would like to try it if the situation gets worse.
Thank you!
