<!-- from fixya rte -->How do I channel auto scan - Televison & Video

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.

Refer its user manual for details.

The auto scan feature scans the various channel frequencies looking for a signal. Weak signals may be picked up on one scan and missed on the next. Check your antenna or add a antenna power booster and try again.

I ran the Auto Scan. Before the scan reached 91%, I pressed the Menu button on my remote and all of the channels that it found locked in.

you may be able to do a manual scan ion each channel which is similar to auto scan.
Its normal for auto scan to select random channels when scanning.

I have experienced exactly the same issue on two Westinghouse sets. Try turning the set off when it reaches 83%. When I turn mine off and back on, it has saved the channels -- at least the ones it had found before it got hung up.
