How to scan channels - Toshiba 32AV502U 31.5 in. LCD HDTV

I can provide some general steps on how to scan for channels on a TV: Make sure that your TV is connected to an antenna or cable input. Turn on the TV and go to the main menu or settings. Look for an option to scan for channels or auto-tune. This option may be labeled as "Channel Setup" or "Channel Scan." Select the option to scan for channels and wait for the TV to complete the process. This may take several minutes. Once the scan is complete, you should see a list of available channels on your TV. If you're still having trouble, I suggest referring to the user manual that came with your TV for more specific instructions. Alternatively, you can try contacting the manufacturer's customer support for assistance.

Do you have an outside antenna? If so start scanning for individual channels at 000. Move 5 degrees scan for individual channels again. Move 5 degrees more. You must scan for individual channels. A wide range scan will erase everything else.
Go to Menu. Hit 7343 then mute. This should take you to a menu with a single scan option. It will take a very long time to complete this. Once you have scanned in every direction, be sure to NEVER hit the wide scan.

REPLACE main board!

check weather some of your channel was deleted in the program. just add those channel so you can make auto scan programs.

I couldn't locate the manual for your scanner, but it's basically the same as the BC860XLT, except that the 860 has 100 channels. Other than that, all controls and functions are the same. You can download and print the manual for the 860 here:
