Vizio model vw37lhdtv40a no video but audio works

If you have replaced all the boards in your Vizio D50u-D1 TV and you are still experiencing no sound and a blue screen, it's possible that the issue lies with a different component or a configuration setting. Here are a few troubleshooting steps you can try:
1. Check the audio settings: Go into the TV's menu and verify that the audio settings are correctly configured. Make sure the volume is not muted and that the audio output is set to the appropriate option (e.g., internal speakers or external audio system).
2. Check the input source: Ensure that the correct input source is selected on the TV. Sometimes, selecting the wrong input can result in a blue screen and no sound. Use the remote or buttons on the TV to cycle through the available inputs.
3. Test with different sources: Connect different devices (such as a DVD player or game console) to the TV using different cables. This will help determine if the issue is specific to one particular source or cable.
4. Perform a factory reset: Resetting the TV to its factory settings can sometimes resolve software-related issues. Refer to the user manual or Vizio's support website for instructions on how to perform a factory reset.
5. Update firmware: Check if there are any available firmware updates for your TV model on Vizio's official website. Updating the firmware can potentially fix bugs or compatibility issues that may be causing the problem.
6. Contact customer support: If you have exhausted all the troubleshooting steps and the issue persists, it's recommended to contact Vizio's customer support or seek assistance from a qualified technician. They may be able to provide further guidance or arrange for a repair if necessary.
Remember to exercise caution when working with electronic devices and consider seeking professional help if you are not comfortable performing the troubleshooting steps yourself.

While most HDMI sources work with good audio and video, we have a compatibility issue with audio from a few specific products (eg, DirecTV HD DVR satellite set-top box, DISH Networks satellite set-top-box, and TiVo Premiere XL cable set-top-box). If you are experiencing problems with no audio or muted audio with one of your HDMI sources, then please try changing the audio settings on your problematic HDMI source to PCM or LPCM. Then turn off the TV, remote power from the WirelessHD adapters, and power off the HDMI source. Now power everything back on. If you are still experiencing no audio then please write down the model number of your HDMI source with no audio and contact VIZIO customer support.

Hi,things you will need,

• Video game console
• HDMI cable
• Audio/visual cable.

1. Plug in your video game console's power source.
2. Connect one end of the game console's audio/visual cable into the corresponding slot on the console if you have an older game console. If you have a newer console, insert one end of an HDMI cable into your console's "HDMI OUT" port.
   
3. 
   Plug the red and white ends of the audio/visual cable into the corresponding red and white audio inputs located on the back of your Vizio plasma TV if you have an older game console. Plug the yellow cable into the yellow "Video In" input. Depending on which model of Vizio TV you have, the yellow input may be located either right next to the audio inputs or it could be located a few ports away.
   
4. 
   Plug an HDMI cable into one of your TV's "HDMI IN" ports, if you have a newer console.
   
5. 
   Turn on your video game console and your Vizio plasma TV. Press the "TV/VIDEO" button on your remote to cycle through the various inputs. You should eventually get to an input that's displaying your video game console's home screen.
   

I think that will do.

Have nice day.

Model?

1. I would first make sure that correct "INPUT" setting is registered.
2. Try a different input source such as VCR, DVD or CD.
3. Connect a pair of audio RCA cable to all the VIZIO set's audio inputs one at a time and touch the center tip while the set is powered ON and the input is set to the corresponding seting. If audio circuit is OK you should hear a hum with at least one of the input settings..
4. If still no audio, then it maybe the audio circuit board needs to be checked.

Is simply. get the audio/vido cables and look on the back of the TV and connect from the audio video outputs from the combo to the audio video inputs on the tv. remember the colors of the terminals and connect them that matches the red, white (audio) and the yellow (video). Using the remote locate the button "input" or "source", and select video 1 or 2, depending where you connected it.

there should not be a special setting that you need. When hooking the analog audio to the HDMI 2 input, it should read automatically. Note: The HDMI Input is for HD Video and will only support 640x480 at 60Hz from a PC. Use the RGB
PC input for a greater selection of PC formats.
