I have just bought a new Sharp Aquos TV and successfully paired my Tivo remote to control the TV (except Mute - a known problem). I'm trying to get the remote to control my Panasonic home theatre / soundbar. When in programming mode I can't enter 4 digits either from the list or scanning. The 4th digit starts to change the channel on Tivo.
Hopefully one of the two suggestions below will work for you.
Please try the following which I found the following from an old forum post.
Make sure the AV device and your TiVo box are switched on
Press and hold down Clear and VolumeDown at the same time until the light on top of the remote flashes green twice
Enter the code 1999 to access the AV device code database – the LED will flash green twice
Point the remote at the AV device and press channelup repeatedly until a code mutes the volume for the device – the LED will flash green each time a code is sent
When the volume turns off, press Mute to turn the volume back on
Press VolumeUp / Down and Mute to check that the remote is working with your device. If it doesn’t work, continue to search using ChannelUp until the next code turns off the volume, and repeat steps 5 and 6
When the Volume and Mute keys work, press OK to store the code. The LED will then flash green twice
If you reach the end of the code database, the light on top of the remote will give an extended red flash and exit programming mode.
NOTE: If you think you’ve missed the code for the AV device, you can work backwards through the code database by pressing the channel down button at any time.
Is your soundbar connected to the TV physically (optical etc) ...
If it's a wireless connection, and you have turned the sound via your TV speakers off, in favour of soundbar only output, the remote 'should' be able to alter the volume once the remote is paired to the TV, or is it that pairing you're having issues with?.
It's connected by a High Speed HDMI cable using the HDMI ARC connection.....soundbar to TV
I've tried again, but CLR+VOL DOWN produces 2 green flashes on the remote and as I type in 1999, the 2nd 9 starts to change the channel....bizarre. It worked perfectly until I changed my TV from a Panasonic to Sharp. This must be the problem
