Of course, every TV, whether it is digital or analogue will have a tuner. If this tuner get defective, there will be no reception to any channels. Check and replace it. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy.

You have to make sure it is set to 'AIR' not 'CABLE' when choosing scanning setup.

SOURCE: I have a Vizio VW42LF TV that is 2 yrs old.

The TV processor could have some garbage in it do to a small power surge and if you leave your TV unplug for 40MIN., then that will reset it bad to normal, and if tuner still looks snowy and not getting channels, then the tuner, or main TV module needs replaced.

Using a digital antenna to channel scan for broadcasted channels


It is no different that channel scanning for cable or analog over-the-air channels. You simply ensure that you have selected the digital tuner of the set prior to scanning. Some older flat panel sets do not have integrated digital tuners. A digital antenna alone will not allow these sets to receive digital broadcast channels. A converter box is needed to convert the digital broadcast signals to analog for the tuner in the set. Also, sets that do not have digital tuners may not support the resolution rate of digital TV broadcasts. Most digital HD broadcasts are 720p and a few are 1080p.

How do I add the HD channels picked up my HD antenna to the master channel list on my Visio TV?


Hello, with the set on, press the menu button, move the cursor down till the "Tuner" section is hi-lighted, click on it. Then the first selection is "Tuner Mode" click on it, the choose "Antenna" click on it. Then move to the "Auto Channel Scan" and click on it, and let it set all your channels. when done, just exit menu and change channels as desired. you can go to page 39 in your manual for these instructions: Tuner Mode
Select Cable or Antenna depending
upon which equipment you have
attached to the DTV / TV Input.
Auto Channel Search
Automatically search for TV channels
that are available in your area. Be
sure to first select the correct tuner
mode above. The TV will search for
analog and digital channels. When the
search is done, press EXIT to begin
watching your programs. thanks, Terry

GV42L vizio tuner


Your vizio has an internal digital tuner. When you are on air, make sure that it is set up for digital. It might say DTV. Some sets have an analog only and digital only program option in the user menu, or as a seperate input. When in doubt, check your user manual.

Initial scan only finds 20 analog channels and nothing else.


What type of antenna do you have and is it pointed at the transmitters? Use antennaweb.org or tvfool.com to check your antenna type and direction for your location. Antennaweb is very conservative in the channel listing even though the site assumes an exterior antenna. Tvfool lists the channels and the respective antennas with a color code that matches the manufacturer's labels for the antennas. Tall trees and buildings can block the signal.

Digital signals are either on or off for the tuner (either there is enough signal to process or no signal). Are you sharing the antenna signal between devices? An amplifier may help.

If you are using an antenna that is pointed correctly and should receive the stations around you, then the problem may be the ATSC tuner. This is on the same board as the NTSC (analog) tuner for most TVs these days.

I hope this helps.

Have a vizio lcd tv . can not get any channels today with the switch over to digital. i use an antenna


Your TV probably does not have a digital tuner connected to the DTV/ANT input. Mine didn't. I had to connect the digital antenna to a digital converter box THEN go to the DTV/ANT input. Only then would it activate the DTV menu and allow me to scan for channels. If your TV worked fine with Cable TV connected to the input, it was because your signal was coming from the digital tuner in your DVR, or your cable provider was sending you an unscrambled digital signal (not likely).
I used a digital converter box I had purchased with the government $40 coupon back in 2009 but the resolution is only 480 and looks like a Monet or Renoir. Now I am shopping for a high quality tuner.

No digital signal search


Check your manual to see if it has 2 tuners, digital and analog. If it doesn't have a digital tuner, you will need a converter box.

Just to make sure, you do have analog tuners setup right?  Media Center 2005 requires analog tuners be working before digital tuners are allowed.
