Remote gives me a wrong channe.

Does this happen with any other channels?

Just a theory, but it is possible that you don't have a Channel 12, or are unable to access it. In some cases, this will cause your TV to go to the next/closest available channel--in this case, 64.
 


 
No, I have channel 12 but I have to go to channel 10 and then go up from there to 12. This is the only channel that's this way. I even got another remote from Panasonic but it does the same. Mystery :) Thanks
