Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts. . http://electro-medical.blogspot.com/ In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here.

SOURCE: My Vizio TV tells me,

Funny, same thing happened to me about the same time! Took me a while to figure out how to fix it. You have to get to the HDTV Settings menu and hit the Help icon. Do a Clear Memory/(Factory Default) and go thru that process, basically you go through all the settings just as you did the first time you powered up the TV. This will fix your problem.

The challnge is...how to get to the HDTV Settings menu when your VIA button only brings up the error you described? I finally got there like this: Hit the "Input" button on the remote, navigate to "TV" and hit OK (basically just select TV as your input), hit the Menu button on the remote and that will bring up the HDTV Settings menu and then proceed as above

Hello,
The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to. This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.
The TV is receiving current but cannot circulate or transfer the current to other necessary part of the TV because of the defective power supply board. You might be lucky it's just a blow fuse. Also a defective transformer can cause your TV not to power on.
All these can be checked on the power supply board.
But more often bad capacitors causes problem on the power supply board. I do not think the power board needs replacement, rather those defective capacitors is causing this issue. Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.
The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes)
You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.
What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).
You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors). After replacing these capacitor(capacitors) most likely the normal operation will be restored. Or you can by a refurbished complete power board to save you some stress.
Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.
If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.
I hope this helps.
Regards.

My vizio tv turns on but had no display


UNPOWERED INPUT DEVICE

Check to make sure the device you're trying to use with your TV is plugged in and turned on. While it may seem like a silly oversight, it is possible that you switched on your TV and didn't actually turn on your DVD player, gaming console or whatever device you're trying to enjoy. If you tried to use a remote to turn on the device, check that the batteries still have a charge and turn on the device using its built-in power button.
TIP The problem may be your input device itself. Check your TV with other devices and see if it displays them properly. If it does, contact customer support for your device for more detailed troubleshooting instructions

WRONG INPUT CHANNEL

Make sure that your TV is on the right input channel for the device you're trying to use. When your TV isn't switched to the right channel, no visual or audio input from the device will display on your screen or through your speakers. Turn on the input device and press the Input button on your remote to cycle through your input channels until you see the device's display on your screen.

AV CONNECTION PROBLEMS

If you're on the right input channel and your device is turned on, there may be a problem with the physical connection between the device and your TV. Make sure that all cable connections are secure, and also that all cables are connected to the In ports on your TV and the Out ports on your input device. If you're using a connection that has color-coded plugs, make sure the connectors are inserted into their appropriate color-coded ports.
If you're using an HDMI connection, make sure that the cable you're using is compliant with High-bandwidth Digital Content Protection, especially if your TV and input device are both HDCP-enabled. HDCP is a copy protection system that prevents the copying of digital video and audio content as it travels over the connection. Systems connected with non-compliant cables won't display any video or audio conten

FROZEN TV

Periodically a TV may freeze up, showing that it's still turned on but not actually displaying any information from your input device or the TV's menu system. To fix a freeze, power cycling is the best solution. TEP 1 Turn off the TV by pressing and holding the Power button on the cabinet until the TV powers down.
STEP 2 Unplug the TV from the wall power outlet.
STEP 3 Press and hold the Power button on the cabinet for 30 seconds, and then release it.
STEP 4 Plug the TV back in and turn it back on using the Power button on the cabinet or your remote control.

HARDWARE OR SOFTWARE FAULT

If everything is correctly set up, powered on and on the right channel and you still aren't getting any picture or sound, there may be a hardware or software fault in your TV. The best way to check is to press the menu button on your TV or remote and see if the on-screen menu appears. If the menu doesn't appear, contact repair

3. Use the arrow buttons to highlight the setting you wish to adjust, then press left/right arrow buttons to change the setting:

Lastly have you tried restoring the TV to factory default settings.
To restore the TV to its factory default settings:
1. Press the menu button on the remote. The on-screen menu is
displayed.
2. Use the arrow buttons on the remote to highlight system
and press ok. The SYSTEM menu is displayed.
3. Highlight reset & admin and press ok. The RESET & ADMIN
menu is displayed.
4. Highlight reset TV to factory defaults and press ok.
5. If you have changed the default parental control passcode,
enter it now.
The TV displays, "Select Reset to restore all TV settings to
factory defaults and clear all account information."
6. Highlight reset and press ok.
7. Wait for the TV to turn off. The TV will turn back on shortly
afterward and the Setup App will begin

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!

Can't change channel using the remote or buttons on tv


Simple Fix

I had the same problem, couldn't change the channels with the remote or on the side of the TV. This was for a Vizio 37"

Here is the fix:

1. Turn on TV

2. With remote, press the Menu Button

3. Go to Antenna Menu

4. Select Auto Search
Let it search, it could take several minutes. It may not finish to 100%, mine got stuck at 79% for 10 minutes. It's fine if that happens, go ahead and cancel.

5. It should be done, your remote will work perfect along with the TV channel buttons.
