Thanks! This helped me. But I did it differently.
#1. Firt I disconnected the power cable to the TV and waited 15 seconds before I reconnected it.
#2. Start the TV. (I started the TV with the remote because the power button was the only working button on the remote)
#3. Hold down the “Back” and “Play/pause” buttons on the remote to start the pairing process. Keep holding the buttons down until you get a message on the TV that it is connecting/pairing with the remote.
Voila! Now it (might) work! =)
For me, the pairing process didn’t work before I disconnected the power cable. I tried several times before without any luck.
Also, the remote controls (red) light blinked constantly as soon as I pressed any button after reinstalling the batteries.
All this got fixed after doing these steps.
And I did not loose all my settings on the TV.
Although I don’t promise that it won’t happen for you…
Good luck and buy a book!
