SOURCE: Have a vizio model M190VA

What source is connected to the TV (what input is it looking for)? Check that the cables are fully connected and undamaged. If the source is a set-top box or dvd player, make sure the device is on and works for another TV. If the source is OTA, make sure the antenna is pointed in the correct direction and is getting sufficient signal. (Try antennaweb.org or tvfool.com for antenna direction and signal strength. Antennaweb is very conservative in the list and assumes an outdoor antenna.) If you have an amplifier or splitter, try eliminating them to test just the one tv (I've had several amplifiers turn into filters that blocked one station after lightning strikes). Try rescanning for channels.

Try another station or source. If none of these ideas help, you may have damage to the video input board or a problem with the cable from that board to the rest of the TV. If the tv is out of warranty, open up the unit and remove the shielding. Look at the boards for obvious damage (soot, scorch marks, leaking capacitors (look like cylinders on tripods)). My usual source doesn't list parts for this model TV but you may be able to find the board with the part number on the board itself.

I hope this helps.

Blue screen Vizio how to take it off

My Vizio Has a Blue Screen But Doesn't Shut Off Troubleshooting your Vizio TV requires that you first identify the source of the problem. A blue screen on your Vizio TV can indicate that you are experiencing a problem with the video input on your TV, while the failure to turn off may indicate that there is a problem with overcharged internal memory or your power capacitors in your TV.

Finding the cause of your Vizio's problems can involve trial and error.

Check Your Connections The connections leading to and from your Vizio TV may be responsible for your Vizio TV having a blue screen and failing to power down. Tighten the coaxial connections to your TV and firmly press in any HDMI, component or composite video cables connecting to your TV, then check the signal on your TV to see if the blue screen problem resolves itself.

Discharge Your TV's Memory Overcharged internal memory can lock up your Vizio TV and prevent it from changing channels or turning off. To discharge your TV, unplug your TV and press and hold the "Power" button for 30 seconds. Plug the TV back into the electrical outlet after 30 seconds and check to see if the problem persists.
Change Input
The input source connected to your TV may be malfunctioning and preventing your Vizio TV from powering off. The "Input" button on your remote will allow you to select a new input source. Cycle through input sources until you find one that displays an image on your screen and power the TV off. If this method works, you may need to replace the input source preventing your TV from turning on.

Power-Cycle Your Equipment Power-cycling your equipment can solve errors created by devices or with your TV's power supply. To power-cycle your equipment, unplug your TV from the electrical outlet along with any devices connected to your TV. Plug your TV back in and turn it on. Plug in each device, one at a time, and notice if your TV displays a blue screen or has trouble turning off. Repeat this process for each device connected to your TV and replace any devices causing problems with your TV.

Can i turn my vizio m190va tv into a computer monitor?

Unfortunately. the HDMI port on the M190VA does not interpret the signal from a computer. The HDMI signal from a set-top box is different than that of a computer. You need to use the VGA port and the PC audio in on the TV; if your computer doesn't have a VGA port, use a DVI to VGA adapter or other appropriate adapter. You will need a 3.5 mm audio patch cable to use the TV's speakers. See page 25 of the M190VA manual here: http://store.vizio.com/documents/downloads/hdtv/M190VA/364User%20Manual.pdf .

I wish that I had better news for you.

The tv had blue screen briefly showing "no signal" then turns off. ... and I am getting the same blue screen-no signal.

If your television is displaying a blue screen or no signal message and then turning off, your TV may be at an inactive input. Here's how you can get back to watching your TV:
1. Powering on your TV and press the INPUT button on the VIZIO remote control repeatedly until a picture re-appears.
2. If this does not work, try again but press the button slower this time.

I got this off the vizio website.
