@Tony Levy That is interesting that a power off makes it work again. When the remote cursor function is failing, does the HOME button still work? Can you also select your different APPS (e.g. YouTube, or Netflix etc)? If thos are also failing, then the Bluetooth Module in the TV is failing in some way, or drops the "pairing" after the TV goes into standby. Some users are posting that some LG TV models suffer from this little internal combo (Bluetooth & WiFi) module can get too warm, and drops the pairing of the remote. Is there anything under the TV (such as an AV amplifier etc.) that might make the issue worse, with heat rising INTO the TV above it?

@Tony Levy Most of the "magic remotes" use 2 different technologies to support the buttons. Some use regular "IR" (Infra-Red) like standard remotes, while other buttons (like the HOME button, and the ballistic "red cursor") use Bluetooth (like a wireless PC Mouse). Test that your Bluetooth functionality is working on the TV side by pressing the Home button. If it works OK, and you can select your TV APPS with the left and right, then the Bluetooth side is working, and the issue is likely to be the remote itself, possibly the ballistic motion detector "chip" inside it. If the Home button does NOT work, check out how to Re-Pair the remote with the TV Bluetooth. Try this if pairing is the issue:

@T0BlAS FYI: there may be another setting section for actual country or region coding. Those other numbers may be "subordinate" to the "region" (say Europe, Asia etc), and country codes. Make a note of them before you change them as the TV could become inoperative. I found this in a related forum, but was from 2015, so later TV models may well have a totally different setup or menu options. The country code for UK appears to be 3122. "I have LG 60UB850T purchased and using it in Dubai. Managed to change location using LG Service Menu Explorer app for Android downloaded from Google Playstore and installed on my Samsung 10.1 Tablet. With TV on, run the app and select Infra-red as means of connection. App opens to look like remote control. Press button which looks like a 'red Wand' icon on right hand side. You are asked to enter one of two codes, mine was 0413. You are now presented with EX-ADJ menu, scroll down to 'Area Settings' using the down arrows and press enter. Change the top line 4 digit to the code of your choice. 3122 for UK, 1793 for US etc. Press 'red wand' until service menu closes and just have TV, reboot the TV (turn off then on). WEBOS should reload. Go to TV settings menu and select Location, your selected continent should be selected all you have to do is select country of service."

@-ethan- Have you let your local country LG SUPPORT site know that this is now an issue/bug? This is only an LG peer to peer information site, and is NOT owned or run by LG. Subject matter Experts and enthusiasts MAY have answers or workarounds, but Firmware bugs are the responsibility of the manufacturer to fix and put right. The more users contact them and report issues, the quicker it will get fixed.

@anand shinde OK, thanks for confirming the model number, and that it happened after a firmware update. So, did you investigate what WiFi band you are using (2.4GHz or 5GHz), and what the SSID names are for these bands, that your router is broadcasting (see the 8 characters and over issue)? There could ALSO be another issue, regarding using high channel numbers, as the later firmware may have tightened up some channel range/restrictions for different countries rules (or maybe even got the tightening up too strict). The info below makes the assumption that you can log into your router, and you are able to view the advanced WiFi settings, and see the channel it is using for the 5GHz band. NOTE: if your WiFi is often dropping in and out due to the issues mentioned, it may well need you to re-input the password if it thinks it is a new connection. I know that should not happen if it has a previous "record" of the correct SSID name, BUT this firmware update could have introduced a buggy setup on the WiFi interfacing. I will reproduce my post on this below for your comment and feedback (as some users have found this fixes the 5GHz side for some TV models): "For those who get frequent WiFi connection drop-outs, I picked this bit of useful info from another forum. Note that this may well apply to many other LG models than the C9, as they often use common WiFi internal cards/modules: "Network/Ethernet/Wi-Fi Problem: C9 [or other models] will lose the wireless connection and you have to reconnect daily (but wired is stable); Conditions: TV is connected to a 5GHz router; Cause: (1) the router may be unstable on the 5GHz band [possibly too far from router]; (2) the router has the 5GHz band set on a higher channel - over 100; Resolution: (1) change the TV to the 2.4GHz band (2) set the channel [in the ROUTER advanced WiFi settings]!! for the 5GHz band below 100 (ex. 40-50) - [channel 36 is often OK]."

@anand shinde Is this the 43UK6780PTE TV model you were posting about back in June? 1) When did this start to happen? 2) Has anything changed since then (firmware update, New router, New ISP, change from 2GHz band to 5GHz band on the WiFi)?? 3) what is the SSID name of your network on those bands? 4) Have you checked with you phone near the TV to see what the signal strength is (The WiFi bars icon, NOT the phone tower signal strength). Ensure you check the same band that the TV is using. NOTE: for item 3, the reason I ask, is that some models of LG TV do NOT like connecting to SSID names with LONG names (over 8 characters, and/or with special characters in).

@Michiel Romme The initial password for LG Signage Control manager is 1105, but some OEM designs or added software layers might change it, and lock further changes to it. I assume you purchased a used item, and want to change something? What model is it? If you need to "get into it" and change stuff/settings, etc, try a factory/default settings (from user settings -> general I think).

@Mark67 FYI: now that SSL security certs only last 364 days, this is going to catch many site admins out, with remote working etc. They all have to me more vigilant, and renew them on time!

@Sushith I saw somewhere on here that the Location Code is 4816 for India. I suspect you wil need the LG service menu explorer APP for your phone to get to that, or follow the "how to get to the service menu" articles on various LG forums. I think I saw that there is an "LG service menu India" on the Play Store for phones, but I am not sure what will work best for you.

@Kuldeep Patel There are many sites that will not load in the LG WebOS provided browsers, even in the latest TV models. The browser is often not compatible with some sites (or sites are not catering for "older" style browsers). See the post below: https://www.lgwebos.com/topic/5877-modern-web-browser/

@Brennan Phoenix I wholeheartedly agree with your excellent post. It is great that you have"pointed the finger" so well, with facts and figures that they cannot refute and excuse. As you and others are saying, this current state of affairs with such an important Smart TV function (a workable and updateable browser), compared with the equivalent Android situation, positions LG in a very bad light compared with other manufacturers. This has certainly opened my eyes VERY WIDE, so when I am ready to change my TV, LG may well be very low down the shopping list!!

@Noel Walker As the poster @dimitrislinuxos stated in his YouTube video, his simple solution worked. Did you try it (you have nothing to lose): https://youtu.be/LkwtA2X2TSs

@Pukahouse It may depend on your LG model, but have a read of this: https://ccm.net/faq/40739-how-to-change-language-settings-on-lg-smart-tv

@Mohd asim You will have to ask your LG company site in your country to see when/if it might become available. This forum is just a user to user forum, NOT and LG owned site.

@Akash Akash FYI: just because a web site shows something is a JPG or JPEG file, it is NOT necessarrily that file type. It might surprise you (or not), that the TEXT for any link in any page anywhere, can in reality be something entirely different. That in itself is one of BIGGEST security issues on the Internet today, and is down to how HTML is defined to work as it does. Many users do not even know that (on a PC browser anyway), placing the mouse-cursor over a link will show the REAL URL LINK for what the text represents. Likewise I could take any file (say a bad malware file, like a .EXE), and rename it as goodfile.jpeg and when you click on it to call your photo viewer, it might try to execute something bad, and put a trojan on your PC. A TV browser may well be designed to check the REAL file type, and ignore it if it was not a real picture file.

@Kunal Mali Unless you are a registered developer, and you have an LG TV set up in developer mode, you cannot add any .APK you want to your TV. LG controls WHAT is allowed on THIER LG Store APP for any given location/country. Copyright and program availability (and functionality) varies widely from country to country.

@ErnieS I suspect your TV update has made it fully "AirPLay" compatible. So from https://discussions.apple.com/thread/5864965 Use this setting to require a specific code to AirPlay to the TV. When an AirPlay-enabled device attempts to connect to a TV with Onscreen Code enabled, enter the passcode shown on the TV into the device that’s attempting to connect to the TV. (From the iphone settings, I assume that : Settings > AirPlay > Onscreen Code > On (i.e. the requirement is set to need pasword) To Set a password Use this setting to require a password for AirPlay-enabled devices to connect using AirPlay on the TV. Use this setting for devices that will need permanent access and you only want to enter the password once. Settings > AirPlay > Password > [set password]

@Leonard King Hi, I just happended to re-visit this interesting post of yours back from August. It seems that the Samsung sound-bar power-down during idle/no-signal can be set to OFF mode. However, I am unsure if the problem as you described it, is that since the FW upgrade, even with an active sound signal, and eARC active, the Samsung Sound bar was STILL powering down unexpectedly when before it was not? Anyway, here is the link to do that, and you could then enable eARC again, to get back the CEC power-control functionality etc. : https://www.samsung.com/in/support/tv-audio-video/why-sound-bar-switches-off-on-its-own/

@Karan Batra That is more for fixing DHCP and IP assignment issues or IP address conflicts. The issue I was posting about is to do with the fact that some devices (Smart TV's, some tablets, older or weak devices etc) have difficulties with high channel numbers, plus the fact the higher channel numbers means slightly higher frequencies within that 5GHz band, and more chance of signal strength issues due to obstructions (or thick walls, steel frames etc.).

@Ravichandran S I have the same model, and mine too, and it is is stuck on that "2337" release of the WebOS. I note that the article you quote is dated 2015. Although updates may provide security updates, and changes to the "apps" side of things, I believe that the internal hardware to provide feature capabilities in the mainboard (e.g. HDR and other stuff), do not support what WebOS 2.0 and above might need to work. If there are others on this forum who are more knowledgeable, please chime in with more precise reasons/info. The latest firmware on the LG site is still only the July 2019 version "starfish-dvb-secured-goldfinger-23.ashley.goldfinger-2337-05.05.90-prodkey_usb_V3_SECURED.epk" inside the ZIP file. NOTE: If you do NOT have this, note that the download will result in just a file called "software" with no file-type extension. I would suggest you right-click and rename it to "LG_UB_FIRMWARE_050590.zip" so your PC can then unzip it, so you can copy the file to a USB stick if you need it.

@Christonian Interesting that it fixed it for a bit. Sounds a bit like software/firmware IMHO. I would contact LG support directly to see if they know if it is a known issue with the C9 and that firmware update. I think I have seen other complaints about B7 and C9 flickering. Push the issue and insist on a replacement under warrantee if they try to fob you off.

@George Hofmeister I am sure you are correct about the LAN side (100mbps, no 1Gbps LAN yet) but most newer LG sets have WiFi 802.11ac support, so that should be much higher than that, especially on the 5GHz band). @Amir Abulajras have a look at my post about a snippet I found on another forum (if you are using the 5GHz band, ensure you are using a channel below 100, I find 36 works well - I assume you are able to log into your router OK, for you to do that change of channel under the WiFi advanced settings or setup) : "Network/Ethernet/Wi-Fi Problem: C9 [or other models] will lose the wireless connection and you have to reconnect daily (but wired is stable); Conditions: TV is connected to a 5GHz router; Cause: (1) the router may be unstable on the 5GHz band [possibly too far from router]; (2) the router has the 5GHz band set on a higher channel - over 100; Resolution: (1) change the TV to the 2.4GHz band OR (2) set the channel [in the ROUTER advanced WiFi settings]!! for the 5GHz band below 100 (ex. 40-50) - [channel 36 is often OK]."

@Hblone Apologies I did not notice that your locaton was Italy, and your problem is with a recently purchased Italian variant LG TV. It does seem odd that older model has a working Time Machine functionality, but the newer model would have a restriction (maybe due to cost, or difficulties with current copyright laws in Italy). Have you tried contacing the shop where it was purchased from, or LG Italy directly, for comment? This forum is NOT an official arm of LG (they might look at it if we are lucky, but I don't think they officially comment here directly).

@Hblone I see from the spec here: https://www.lg.com/uk/tvs/lg-55un74006lb that it shows "Time Machine (DVR) YES" so the recording functionality IS there, but it will need a small self-powered HDD (external backup type of hard disk) plugged into the USB3 socket to activate the recording functionality that the TV has. NOTE: the new disk when added, may trigger a recording "setup" automatically anyway, so be aware that it may well want to format it to the TV requirements (file structures, folder names etc), that may take a few minutes. Use Velcro or a cable tie to hold the external disk in a convenient place, so that it does not strain the connection cable (NEVER let it hang from the cable). I would use about 500GB or a 1TB HDD drive, depending on the amount of recordings you want to do, and if HD quality or not. ALSO: be aware that even when in standby, the TV will still have enough "smart electronic logic" active to do the scheduled recordings on its own, it does NOT need to be in the ON state, BUT DO NOT TURN IT OFF AT THE WALL SOCKET OBVIOUSLY! 😊 If you have a smart remote, you might find the "Q.MENU" button, or one button marked "123" to get to your settings. If you had a separate manual for your remote or TV, have a good read to see if it helps with the recording side. It MIGHT be the "settings" cog button on yours, I am not sure. I find the Time Machine scheduling a bit clunky and non-intelligent on my older LG, but you may find your later one is smarter? A typical issue is that (unlike a set-top-box like Sky) it will not necessarrily "track" any time changes to a scheduled program if it starts late. If you adjust it to start at an earlier time, then the "File/program name" will reflect the PREVIOUS program title, and NOT the actual one that is the main recorded program!! I know that the smart remotes have a good voice command function, so press the button to activate the microphone and try saying "time machine". I find the voice command useful to get to "settings" with my older magic remote, as I can never remember how to get to it on my TV otherwise... 😊 By the way, I find that Toshiba, Western Digital, or Seagate portable USB3 drives are good for this, use this Google search term to see what is available in your area: "site:.uk Western Digital portable drive" or "site:.uk seagate portable drive" without the quotes. The site thing limits sites to your country/area/locale so avoids generic ".COM" sites usually.

@Christonian Thanks for confirmation.I just spotted this on another forum for LG C9 flickering/flashing bright: "Its related to the « Logo Luminance » setting...just turn it off and you will be ok". I do NOT have a C9, so cannot verify that, but it is worth a go. Others said it fixed the issue.
