When I turned the tv on it is showing a message SELECT ANTENNA TYPE AND PERFORM CHANNEL AUTO SCAN FROM TV MENU I tried this several times and it just keeps taking me back to a screen with this message after the scan is complete.

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.

If your Viore TV is unable to scan digital channels after a power outage, there are a few things you can try to fix the issue:

1. Check the TV's antenna connection: Make sure that the antenna is securely connected to the TV and that there is no damage to the cable.
2. Rescan for channels: Go to the TV's menu and select "Auto Tuning" or "Channel Scan" to rescan for channels. Make sure to select the option for digital channels only.
3. Check for software updates: Make sure that your TV has the latest software updates. Go to the TV's menu and check for any available updates.
4. Perform a factory reset: A factory reset will restore your TV to its original settings. This can sometimes fix issues with channel scanning. Consult the manufacturer's manual for instruction.
5. Check your TV's location: Make sure that your TV is in a location where it can receive a good signal. Try moving the TV or the antenna to a different location.

If none of these steps work, it's possible that the TV's tuner may be malfunctioning and may need to be repaired or replaced. Contact the manufacturer's customer service or a professional technician for further assistance.

go to the Menu and you should find it.

If you are receiving a "No Signal" error message, verify that:

1. All of the cables physically connected to the TV and the input device are secure.
2. The input device is turned on.

Your TV needs to scan for channels before it can show programming from an antenna, from cable TV when the cable comes directly from the wall (no cable box), or from a cable or satellite box connected to the TV with a coaxial (RF) cable. Do not scan for channels if you have a cable or satellite box connected using AV (Composite), Component, or HDMI cables. The box selects the channel, not the tuner inside your television. If you are not using the "TV" input, press the INPUT button on your remote until the correct input mode is selected.
To perform a channel scan using the coaxial input:

1. Press the INPUT button on your remote to view your current input source. The TV (coaxial cable) input must be selected. This may appear as "TV," "ANT," or the channel and call letters of a station.
2. If the TV input is not selected, press INPUT until the TV input mode is selected.
3. Open the on-screen menu and select TV or Tuner option. (This varies by model.)
4. Highlight Tuner Mode and select the correct option:
   • Antenna-over-the air signals from an antenna
   • Cable-direct from the wall cable TV, or a cable or satellite box connected to the TV with coaxial cable
5. Select Auto Search or Auto Channel Scan. (This varies by model.)
6. When the search reaches 100% complete, exit to the menu.
7. Check the available channels:
   • Antenna or direct-from-wall cable-Press the Channel Up and Channel Down buttons on your VIZIO TV remote to view the available channels.
   • Cable or satellite box- Will return only one channel. Use the cable or satellite remote's Channel Up and Channel Down buttons.

If this does not resolve the issue, power cycle the TV and then re-run the channel scan:

1. Turn off the TV.
2. Unplug the TV from the electrical outlet.
3. While the TV is unplugged from the wall, press and hold the Power button on the TV for 30 seconds.
4. Release the power button.
5. Plug the TV back into the electrical outlet.
6. Turn on the TV.

Note: There is also an option to reset the TV to the factory default settings. This option is in either the SETUP or SYSTEM section of the on-screen menu. The option may be "Reset all settings", "System Reset," or "Reset & Admin." Consult your TV's user manual for the location and steps for resetting your model.

1. Remove the coaxial cable from the DTV/TV connector on the back of your television and perform a channel scan to clear the existing channels. See the procedure above. This should not find any channels.
2. Re-attach the coaxial cable to the DTV/TV connector and perform a new channel scan.

You can autotune your Sony TV without a remote control. Fist connect it to an external antenna or cable whatever may be, to its antenna socket at the back side.

After you have finished connecting your TV, you can use Auto Program to set up your

program receivable channels.

[1] Press POWER button on the TV to turn it on. The Initial Setup screen appears.

What box - satellite/cable/digital-to-analog converter? This tv has a digital (ATSC) tuner built in. So if you are looking for OTA channels, use antennaweb.org or tvfool.com to find out what direction to point your antenna and what antenna you need. Then connect the antenna's coax cable to your TV. Antennaweb is very conservative and assumes an outdoor antenna. tvfool.com will list several more channels and the different antennas that are needed for various distances between your location and the station transmitters.

If you are sharing one antenna between several tvs or tv and other devices, you may need an amplifier in addition to the splitter. (Unfortunately, these can get damaged by surges as well. I've lost certain channels after a lightning strike turned the amp into a filter for one part of the RF signal spectrum.)

Once you have the antenna connected and pointing in the direction of the desired station, you will need to scan for channels. If this is the first time the tv is set up, you will be prompted for menu language, the input type and then asked if you want the TV to auto-scan for channels. Otherwise, hit Menu, use the left and right arrows to get to the Channels menu option and press the + button in the center of the arrow keys. Next use the up and down arrows to set the incoming signal (if needed) - the item is labeled Cable and is a Yes/No (again press + to select item and to enter the change). Continue down to the Auto-program and let that run. You can add/remove channels from the resulting listing with the Channel Skip/Add option just below Auto-program.

I hope this helps.
