I hope this is in he right section.
I have a LG TV which uses the AKB74915324 remote https://www.amazon.co.uk/Genuine-LG-AKB74915324-Remote-Control-BLACK/dp/B0724ZDFV7
and an LG home theater system which uses the AKB73775813 remote https://www.amazon.co.uk/LG-AKB73775813-Remote-Control-Blu-ray/dp/B009TTXVZ4
Up until recently the home theater remote worked fine on the TV using the buttons on the bottom of the remote to turn the TV on or off, or to change input etc.
However in the last few days this no longer works.
Anyone any idea how I can pair it back to control the TV?
