Error message "please run channel auto scan"

[SammiCanada]

I have 2012 rca lcd tv model rlc2685a-b. I can't get rid of this error message, and the input source keeps resetting to "tv" instead of "HDMI1" so i cant use the satellite digital box to update the channels. Do you know how to fix this? Thanks!

The error message has nothing to do with the sat box.
The TV may require you to do a channel scan regardless if you want to use an antenna or not.
Go to the TV set up menu. Choose over the air antenna and run the channel scan. You can attach an antenna before you do it and use it as a backup for when the sat goes out due to weather conditions. If not then it won't find any channels and should then let you use HDMI1.
