Sudden no signal on digital channels on a Vizio VX37L

I've been getting many, not all, digital channels fine on my Vizio VX37L by just plugging the wall cable in.  I decided to run a channel search to see if I could get more channels.  After the search, I was only getting the regular channels.  When I land on a HD channel, it says no signal. 
I have found nothing in the booklet on this, nor is there anything on the menu to choose digital signal.
Anyone know how to resolve this?

    it's just the cable from the building.  i guess it serves as an antenna, but i do get some cable channels without subscribing to cable.

    but it was there, fully.  until i did the channel auto search which seemed to kill it.

That may not be correct. You would not lose all your digital channels. Vizio has an un-addressed problem with losing digital stations. Multiple threads are posted due to this problem, which is why I am on this site. I have lost all digital stations on CATV connection. The Toshiba set in the next room is getting over 150 DTV channels, the Vizio, only analog. Zero Digital.

You have to go to your menu screen and change the settings from antenna to cable that should take care of it, and should be able to do a auto scan to load channel memory

This may work for you. My Vizio went black except for the blue channel rectangle in upper right corner; I couldn't change the channels or power off. I called Vizio, was told I needed a hard reset, and this fixed my problem: I unplugged the TV; held down the on button for one minute, then plugged it back in. It works fine now.

Have a Vizio VX37L that when it is turned the


HERE'S THE FIX: I just went through this with my Vizio VX37L. TV is stuck in RGB input. This is the fix.... TV is stuck in RGB input.
(option 1) Power on TV, and press the INPUT button repeatedly and rapidly until you can change to a different input, such as AV.
If that doesn't work, try:
(option 2) With the TV off, press and hold the INPUT button on the side of the TV for about 5 seconds. The TV should power on and the input list will appear. The TV will no longer be locked, and the INPUT button should function properly after that.

Option 2 worked for me!

Vizio 37L suddenly stopped getting all digital channels


I had the same problem with my 42" vizio. Was working fine for about a year and a half, then a month after all stations went digital, I couldn't see any digital channels and it wouldn't scan for digital signals
This is a strange go around, but it worked for me. . Tried unplugging, pushing power button for two minutes... did everything the forums suggest, with no resolve. But, here's what DID work for me. Trust me, it sounds strange, but it continues to work (and, yes... it's not a permanent fix... the channels still go out once in a while, but I can always get them back now)
Use your Vizio remote control. Turn your TV on. Press the "input" button until you get to "RGB", which is what you would connect a computer to. Make sure no computer is connected, or it's at least off if it is connected. When you get to RGB, you'll see a message that says "No Signal". After about 5 seconds, the TV will enter a sleep mode and seem as if it has turned off (orange Vizio logo). Once it completes it's little sleep cycle and "clicks" off, wait a few seconds and hit the input button again. It'll go to the next menu item. Keep clicking input until you're back on "TV", and VUALA! The channels are back! 
I accidentally figured this out when trying to troubleshoot, but I'm glad I did. Didn't want to dishout $250 to get it fixed. Let us know if it works for you too!
