Unpair Magic Remote while tv is off.


Question

Hello,

I unpaired the Magic Remote of my LG OLED 55B7 tv by pressing "Back+Recents" buttons on the remote, while it was off and not connected to a power outlet. The remote control blinked 3 times.

Then I turned my tv on and the tv wasn't recognizing the remote, so by pressing the "Ok" button in the remote, the tv paired with it and displayed a message confirming it.

My question is about the mechanism in all of this: since my tv was off, how did the tv itself forget the remote?

Is the pairing process stored both in the tv and remote?

Will there be some "left over" pairing stored in the tv related to the procedure while it was off?

Many thanks.

@MagicR As this is Bluetooth Protocol, it is a bit like a wireless mouse and its dongle, but smarter. The paired device codes are stored on both devices, as you might have TWO LG TV's, so each TV would need to know which Magic Remote to listen and respond to.

Hello td47, so the codes are stored in both devices (remote and tv).  Since the tv was off while I unpaired the remote, I understand that by doing the procedure the remote forgot the code.

My question is how the tv forgot the code since it was off?

Many thanks td47.

I mean OFF as in unplugged.
Hi! I believe that about this pairing process with the web os tv, there is a similar pairing code both on the tv and the magic remote, whenever you turn the tv of or unplug it or plug and turning it on the code is still the same has the one in the magic remote, when you unplug the web os tv has I said the code remains the same, but when you unpaired the magic remote the pairing code in the magic remote is reset so it change, while the code in the web os tv remains the same, then when you plug it back and turn it on the tv and use the magic remote, it send a signal or command to the tv and the tv does not recognize the magic remote because the pairing code on the magic remote has been change because of the unpaired. Therfore the web os tv show a message to clarify that pairing the magic remote is needed, so you pair again the magic remote and the web os tv so the code on both devices matches again, therefore working together again.

Sorry I use to many word to explain this someone else would have done a better work
Thanks for reading hope you understand what I mean. Have a great day. God bless you.
Bye !

Hello Steel, thank you for your answer and I understood it.

Yeah I believe something similar to your theory.

My theory is that the remote does an "active pairing", storing the tv id. And the tv does a "passive pairing" of the remote id.

When unpairing while the tv is off, the remote actively deletes the pairing information. When the tv is on, the remote sends a "blank" pairing information and the tv receives it and... clears the pairing info of the remote?

      Hello,
      Is it possible to add the driver for external usb 3 gigabit ethernet adapters  in the firmware to support them and get more network bandwith like on the oled TV C9 and CX (see https://www.youtube.com/watch?v=RgJUUNCsHao) to give to the product the ability to play 4K hdr mkv remux of high bit rate blurays without stuttering (like gemini man or billy lynn for example streamed from Plex server with giga network) ? If you play the same file on direct attached usb drive, no stuttering at all and it's ultra fast to load and fast forward for example.
      It already supports external usb2 FastEthernet adapters with ASIX AX88772 chipset and work well on both type A and type C ports, I have tested it, but it is also a 100Mbit/s adapter like the integrated one, so same bandwith, and stuttering is always here.
      The driver that need to be added to the firmware is the one for the usb 3 gigabit ethernet adapters with ASIX AX88179 chipset like on oled C9 and CX, but no luck, at least with firmware 3.0.0.8 it is not supported, eihter with type A  ports or with the type C port (I have tested both, RJ45 leds stay OFF, the same with a power usb 3 hub in between, driver not included in the firmware).
      I have also tesed usb3 gigabit ethernet adapter with realtek RT L8153 chipset, wich is seems to be supported on older oled C7 and C8, but it is also not supported (blinking leds this time but no connection, driver not included in the firmware).
      This is very frustrating for a 1800$ product !

      I recently updated the firmware on my  LG43UH610V.  Now I constantly get "Wired Lan cable disconnected" / "Wired network is connected" messages even while watching a video file from my NAS. The TV is connected and using the network while getting these messages. It has always been on a fixed IP address on the LAN.

      LG Calls on Young Musicians and Creators
      to Express Their Own “Life’s Good” Message
       
      SEOUL, May 27, 2021 — LG Electronics (LG) today announced that its 2021 Life’s Good campaign will consist of two exciting components: Life’s Good Music Project in collaboration with acclaimed singer, songwriter and producer Charlie Puth and the Life’s Good Film, to be directed by rising star Jackson Tisi.
      LG’s Life’s Good campaign gives young people around the world the opportunity to let their creativity and talent shine. First launched last year, the Life’s Good Music Project calls on aspiring, young performers to share their own compositions expressing LG’s uplifting Life’s Good message. Anyone who loves music and can hum a tune is invited to submit an original accompaniment based on the 2021 version of the Life’s Good song, produced by Charlie Puth. The talent behind the winning entries will receive OLED TVs along with other LG products and the opportunity to complete and perform the song with Puth.

      “I can’t wait to listen to everyone’s submissions and hear their take on the melody and chorus,” said Puth. “Music has always been a source of healing and empowerment for me, and I know this is going to be a memorable experience for everyone.”
      This year’s Life’s Good Film will be directed by Jackson Tisi, who won Gold at the Young Director Award 2020 for his moving short documentary, LEON. LG is further challenging the next generation of filmmakers to visually capture the moments and places that have meaning in their lives and how they interpret LG’s Life’s Good philosophy.
      The accompanying Life’s Good Film Project is intended to convey a universal message of hope and celebrate the diversity of experiences and viewpoints of young auteurs from all over the globe through their inspiring, unique stories. Submissions can be made by posting to Instagram or YouTube with the hashtag #LifeisGoodFilm_LG until June 27. Details for participation in the Life’s Good Film Project can be seen .
      “I believe there’s something profound in our everyday thoughts and the places we go to seek inspiration or solace,” said Tisi. “By sharing what we find in our everyday, this film will convey a resonating message of what life still holds.”
      To accompany the 2021 Life’s Good campaign, LG has also created a brand channel on offering a variety of cheerful GIF stickers – including those from both the Life’s Good Music Project and Life’s Good Film Project – for use on Instagram, TikTok, Snapchat and other social platforms.

      hi guys, I have an LG CX65 bought a month ago. it's already happened two times that while I was watching a normal TV channel the fireworks screensaver kicked in. After the first time I did a reset of the TV, but it happened again today. Someone has experienced this issue? If could be useful to know, I have an Xbox series x, a ps5 and a soundbar connected respectively to HDMI port 1, 2 and 3 and the consoles always stays in sleep mode. they works great, no problem at all, and the hdmi cables are brand new.
      the first time the fireworks kicked in while a was watching a news Channel i has only the soundbar and PS4 connected tho.
      I hope you can help me out
