I accidentally removed the pairing between my BeoRemote One and Beovision Horizon (via Pairing > Remove). However the remote doesn't pair with the TV any more (via Pairing > Pair, nor after performing a factory reset of the remote).
Do I need to press something on the TV while pairing or use another method? (It's my parents TV so I'm not sure how they got it to work in the first place)
Fixed this by unplugging the tv and plugging it in while pairing with the remote :)
