HDMI Cable Inspection
As mentioned earlier, this means ensuring that the hardware is not the reason for any problems.
For this, follow these steps and verify where the problem is.
- Switch your Vizio Smart TV off.
- Remove HDMI or any other such physical cables connected to the back of your Vizio Smart TV.
- Clean the contacts of the cable and the connector on the TV if you have any compressed air. If you do not have compressed air, then blow with your mouth on them gently.
- Firmly put all the cables back into their slots on the TV.
- Switch your TV back on again.
If the issue is with the cable or the port, get it renewed or repaired. However, if the problem is not with the hardware device, continue scrolling for other possible solutions.
These might be the problems you will come across during this procedure:
- Faulty HDMI cable with a breakage in it.
- Damaged HDMI port with broken pins.
- Poor HDMI connection, that is, where the cable and connector are not entirely making contact
Conclude based on this and move forward if there is none of it.
Check the HDMI Ports
After ensuring that the issue is not with the HDMI cable, move to ensure that it is not the ports. At times, the Vizio TV might not receive input from a source due to an issue in the HDMI port, which also leads to Vizio TV turning off abruptly.
After confirming no problems with your HDMI cord, try moving it to a different HDMI port on your TV. For example, if you’re using the HDMI 1 port, push the cord to the HDMI 2 port.
If this doesn’t solve the problem, try every HDMI port on your Vizio TV. If you can’t find a port that works, you may need to replace the TV motherboard.
You’ll have to contact Vizio support, particularly if you’re still under warranty.
You can always reset your Vizio HDMI port by factory resetting your Vizio TV.
Turning your TV’s settings to factory settings is a more extreme step, for it will delete any personalized features or connected devices. Still, it’s always worth a shot when other methods haven’t worked.
To factory reset a Vizio Smart TV, refer to the steps mentioned where we talk about factory resetting a Vizio TV for better working.
- Figure Out the Display Settings
If your laptop or desktop PC is connected to your Vizio TV, check its display settings by following the steps mentioned below according to your device:
- On a Windows 10 desktop PC, go to the Start menu > Settings > System > Display
- On an older Windows computer, go to the Start menu > Control Panel > Display
- On Apple devices, go to the Apple Menu > System Preferences > Display
By default, computers only display images and videos on their monitors. You must extend or mirror your laptop or PC’s display onto the TV to show the correct HDMI output.
Also, check that your source device’s resolution is compatible with your Vizio TV. You can find these in the instruction manuals of your devices.
If this does not help, look forward to the next possible solution given.
Check your Device’s HDMI Specifications
If you are operating a fresh Vizio TV, and it is the first time you are plugging in a device, the issue is due to differing HDMI specifications.
The recent Vizio TVs support HDMI 2.1, which is backward compatible with the older versions of HDMI specifications and uses a new cable design for 4K 120Hz viewing.
Check your TV’s current HDMI specifications, the device you are plugging the cable, and the line connecting them.
If you attempt to plug an HDMI 2.1 device into a Vizio TV with an older HDMI port, the device will likely send a signal the Vizio TV cannot interpret.
This can, however, be fixed via the settings of your device.
Move to the next solution if this does not work out as well.
Update Graphics Driver
If your external device is a personal computer, the problem might be needing a video driver.
Get information that devices like Xbox and PlayStation do not require a manual driver installation and that the solution applies to only desktop or laptop devices.
Download a suitable driver and visit the website depending on your graphics card (GPU) model.
If a driver is already installed, check for updates and ensure to apply any updates found.
Are you still waiting? Next are the last few solutions possible for this problem.
Check Input Source
The next thing to check would be the input source on your TV. It may seem simple, but this can be the solution for many stuck with this problem.
When you inserted the HDMI cable, you would have noticed the port was labeled ‘1’ or ‘2’. Click the Input button on your TV’s remote control, and ensure you selected the correct input source. You can cycle through each to check if they need to be labeled differently.
If you need help with those mentioned above solutions, you always have the last resort of referring the problem to the Vizio Support Team.
- Contact the Vizio Support Team
This is the last resort you can look forward to. The Vizio technical support team is always available for you, no matter what.
