No tv signal on my olevia 232-s12

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.

goto menu and channels and some may say " edit or add " that where you will do it. as long as you know the channel # it should go smoothly.

Yes you can use an indoor antenna. Just make sure it is an HD antenna to get the digital channels clearly. You will have to do a scan to pick up local channels. In the TV menu, it will ask you if you want to scan for "cable" channels or "antenna" channels. You want to choose antenna.

You'll need to reprogram the channels.
Typically this is found under the settings in some sort of auto program section of the menu.
On most newer televisions, the setting is found under a 'Channel' section.
Just select auto program and your source, whether it be an antenna or a cable source.
When the auto program is completed, you'll have your channels back.

With remote, hit MENU, (use up/down arrows) & scroll to SETUP. Hit ENTER & scroll to TV. Hit ENTER & scroll to AUTO CHANNEL SEARCH. Hit ENTER & scroll to CABLE. Hit ENTER & scroll to AUTO. Hit ENTER, wait as it scans (about 5 min). Your done.

HDTV sets are different from the old analog sets.

If your set is showing No Signal or Weak Signal you will have to do the following.
1) Connect an Antenna or Cable to the input on the back.
2) Go into the Channel signal source menu and select either the Air/Antenna or Cable option.
3) Go into the Auto Program Scan menu and SCAN in the channels.

Now you can watch available channels.

Are you using a set-top converter box?

go through the setup and have the TV auto programm again. This should fix the problem.
