I have a Tivo HD Series 3.
Just about every other day we will switch from cable to the Tivo and the remote will not work.
Just to confirm….
We get the amber light when a button is pushed but we only get a ‘bonk’ sound.
The remote works fine on all other devices, no problem EVER on anything else.
I have tried both our universal and the Tivo remote.
This is the only remote we have in the room (other than testing the Tivo remote) at all times so no chance of a button being stuck.
There is nothing blocking the view and no interference.
We always end up unplugging the Tivo and letting it boot back up.
We don’t have any other problems that night until we flip back over to the Tivo another night and it happens again.
Any answers out there?
