Hello!

My parents' LG webOS TV had this issue where their Magic Remote has gone insane and every button thinks it is the mute button.

I have tried changing the batteries to brand new ones, letting it fully "de-charge" for 10 minutes, de-pairing it, etc. accordingly to the troubleshooting guide. Not even the power button blinks as it should. Oddly enough, the motion cursor works fine.

I have attached a video to show how it looks.

Any suggestions to fix this?

Try physically turning off the TV by pulling the power cord to the TV, wait a few minutes, then plug it back in and start the TV again.

 

If this fixes the problem initially with the remote control, then go to Settings / Picture / Energy Saving and make sure this is turned OFF.

 

I had similar problems with my remote control which would bog down and become unresponsive, until I changed this setting.

Hey! Thank you for the response.

I unplugged the TV for 10 minutes and after plugging it back I couldn't turn it on with the Magic Remote, had to do it with an external remote. The behavior of the Magic Remote is still the same as the video I posted above. Issue still goes on. 😞

First, I would check for any stuck buttons on the remote itself, and look for any evidence of anything spilled on it, or in it, and check if anything feels sticky in between or near any of the buttons. If there IS anything sticky etc, (or if any of the keys stay down) remove the batteries, and use a mild solvent like Isopropyl Alcohol around and between the buttons (cotton buds can be used for this), until they feel better/free-er. Check the operation of EACH button to ensure none feels as if it is sticky or staying depressed, repeat the solvent if yes.  Allow to dry in the open for 30 minutes, re-check the feel of the keys, if OK, put the batteries back in and try it again.

Hey, thanks for the reply!

I just went to the controller and tested every single button. Each one feels exactly the same, they all make the same "click" noise and none of them feel jammed or sticky. So I don't know...

OK, you have eliminated the keys (maybe), so the keys use Infra-Red, the "blob" pointer uses BlueTooth. It might be just "broken" electronics in the remote, so needs a replacement.

Interference IS a possibility, but rare, so check if yous folks use any Infra-Red "remote extender" devices for any other stuff (hifi, amps, dvd-players, set-top-box etc). Check if any OTHER remotes are near the TV (say stuck down a sofa with a button continually pressed). BLUETOOTH - check if there is a device (bluetooth speakers, notebook/laptop book reader) that might have a dodgy set-up. Turn them off if you can, or remove them to another room, and retest.  My gut-feel is that the remote is just electronically faulty inside though.

Hi, I forgot to ask an obvious question: has there been any evidence of leaking batteries left in the remote? It is a common occurrence, and if run-down batteries are left in any device like this, the leaking chemicals can play havoc with the printed circuit tracks and components inside them. They are often alkaline, and can cause bad corrosion that can lead to partial shorts (low resistance paths) for signals to go to the wrong place, and can seep into the press-button contacts too. Look out for what looks like a "green rust"  around the battery contacts in the remote (if you can see any of the circuit tracks, check those too). Bad corrosion often leaves things like remotes, calculators, toys etc. irreparable, but if you have caught it quickly enough, you MIGHT be able to salvage it, IF you know how to take the case apart (defeating the snap-in latches of the two halves can be a pain), AND you know about removing corrosion from PCB tracks and components. You might get lucky if it is only the button contact pads gone bad, try wiping with Isopropyl Alcohol and cotton-buds.

      Having eARC engaged in the TV settings and sending Atmos etc to an eARC enabled Samsung sound bar causes the sound bar to power down after appx 18 minutes and diverts the audio to the TV's inbuilt sound system. Disengaging  eARC on the TV resolves the problem and still sends Atmos via ARC. This has only occurred since the most recent software upgrade. Anyone else experiencing this?

      Hi,
      I use the YouTube app on my LG OLED55B6V smart TV on a daily basis. Does anyone know in 2020, if there is an external keyboard I can use on the YouTube app? 
       
      Thanks.

      Hi there
      I've had my LG WebOS SmartTV for a couple of months, but in the past week or so I've noticed it's really started eating up all my home's Internet bandwidth, even when I'm just watching FreeSat TV and not running any apps.  It's connected to my router using wired ethernet, so it's not a WiFi problem.
      I can only assume that one the apps I've installed is suddenly decided to download a ton of data in the background.  But which one?
      The only solution I can think of is to install my apps one-by-one until my bandwidth issue improves.  And that's what I'll do.
      But I found this forum, and thought I'd ask you good people if any of you had had a similar experience.
      Here's the apps I've got installed:
      BritBox BBC iPlayer Spotify YouTube Amazon Prime Video NowTV AppleTV Thanks in advance for any tips

      My TV was bought in 2014 55UB850T-TA with WebOS TV version 1.4.0-2337 (afro-ashley). 
      I recently purchased the Disney hotstar subscription. But in the above version the LG content store does not show the Hotstar
      As per the news in this link we are eligible to upgrade to WebOS 2.0. But the automatic updates does not say it as WebOS 2.0 but still WebOS 1.4

      link hidden, please login to view Why this discrimination for old users of LG TV? How will I install new apps in this TV?
      Please help.
      Thanks,

      I have the following setup:
       
      LG 55EF950V television which is running webOS 2.2.0-1317 (this should be the latest version of the OS).
       
      I have a number of video files on my Synology DiskStation DS413 NAS which I connect to with the TV over DLNA (on the TV this is Smart Share -> Devices -> (NAS))
       
      I can see all the video files and play them etc., however when viewing the list of files I dont see any thumb images even though I have a JPEG image for each file.  For example: "My Video.mkv" has a thumb call "My Video.jpg".  For collections I put a "cover.jpg" image in the directory (this doesnt work either on the LG TV).
       
      Has anyone else out there managed to get a webOS 2 TV to show video thumb nail images for videos over DLNA?
       
       
      BTW: this all works when I use a Samsung TV so I dont think it has anything to do with the way the Synology DiskStation DS413 NAS is setup.

      Hi, Not sure if in the right place or if this has been asked before. I have a subscription to the BT Sport App as an add on through my EE Mobile Phone package. I have watched the BT Sport through the web browser for a few months now relatively ok (lagging issues aside), however when I try to now watch anything on BT Sport, the video will not play and the message 'Sorry this video is not available on your browser. Please try again on a supported browser.  Error Code VC088 appears which I have tried researching but nothing seems to work.
       
      Why has it stopped working when it was working previously if anyone has any idea
       
      Thanks

      I’m an owner of OLED55C8PJA. It’s an OLED SMART THINQ TV. I have spent lots of money in this. Anyway, I can’t see Sinhala Subtitles whenever I’m watching movies using this TV. But it supports Sinhala language. It even has menu language and keyboard language in “Sinhala”. But Srt Subtitle files that has Sinhala language cannot see.I have tried to set to encoding to UTF-8 also. But no luck!
      hope you will know solution for me.
      Thanks

      Is it possible to program the 4 color button on the Magic Remote? For example, I would like them to switch to apps like YouTube TV, Vudu, etc.? My remote has 2 buttons just above the color buttons which are pre-programmed for Netflix and Amazon. I want to use the color buttons for other apps. Anyone done this?

      I have webOS TV UH6100, software 04.31.10. 
       
      Sometime in the last week something happened that caused my date, time, and location to be wonky.  I can't set them, and automate detect isn't working.  Same with allow automatic updates.  It says "may take a few seconds" but i've waited 15 minutes to 30 minutes with nothing happening.  Network connection is good - it is able to connect (according to the software).
      I've tried reset factory settings to no avail, because it says the tv will now restart - i get the spinning circle of dots - but it never restarts.  When I turn the tv off and back on, it's still in the same state.
      None of the apps will go anywhere either.
      Any ideas?  Thanks for your help in advance
