What are vertical or horizontal lines on the TV screen

If you ever start up your TV it should be having a normal vivid screen without any weird cracks, glitches or lines. If you happen to notice lines on your television then it is clearly not working right.

These lines are generally of one base color, such as pink or green or red and would be slight in width but would span across one edge to another either vertically or horizontally.

If you are unsure if this is a bug or not, try changing channels or sources and if it occurs on every one of them then it is possible that your TV is indeed bugged.

Why do these lines and glitches appear on Vizio TV screen?

  • 1. Old Television

There are many reasons due to which lines could appear on your Vizio TV screen. For instance the most common reason is old TV sets. As anything gets old it would start detoriating in performance and functionality.

  • 2. Voltage Fluctuations

Another good reason are fluctuations in voltage. This is very less likely to happen. The better the place you live in, the more chances of stable electricity but I remember voltage fluctuations and power outages if a nearby grid malfunctioned.

A surge or sudden depletion in electrical supply could lead to permanent or temporary damage to your TV and other connected devices including lines on it.

  • 3. Physical damage

A very common reason for these issues is the damage to the TV. In most cases it a physical damage, such as dropping the television while carrying it applying impact on the Screen either gradually or instantaneously.

If you accidentally got liquid into the speaker groove or other input ports then it is possible it went to the screen unit and damaged it.

If your TV just got delivered with the lines already, it was probably damaged while being shipped. Try contacting Vizio support team for help regarding this.

  • 4. System glitch

If your software abruptly shut down, or failed in the middle of updating the firmware the TV might still manage to boot up but you would get issues like this.

It is also possible you would experience severe lag and other glitches on your device if this happened, causing your device to shut down multiple times.

This can also lead to more damage to your device so make sure to shut it down until you come to a conclusion and find a solution for it.

How to fix horizontal/ vertical lines on Vizio TV screen

Now that we have discussed the basics of what it is and what it happens, let us talk about what we can do about it.

  • 1. Power cycle

One good way to solve this issue to try out the power cycle method. This method effectively cuts off the power supply and cleans the persistent issues, refreshing the whole system. When it starts next time, your TV might not have the lines!

This is easily achievable by directly unplugging the TV from the power supply. You can also try going into systems and then to Reset and Admin section to apply a soft power cycle if you have the option to. Both methods are just as effective.

  • 2. Checking cables and cords

TV works with various other devices such as your data connection device, your channel broadcasting device, the DVD, VCR and speakers. If you have got a loose connection or a bad input device, it could lead to this.

You can check all the loose cables and wires and make sure they are not damaged. Most cables are quite cheap to buy so replace one if needed. If in doubt regarding whether a cable is fit well or not, always pull it and re insert it again.

  • 3. Access the other parts of Vizio TV

To confirm this issue is indeed of your own TV and not of any other device, you can change the channel, try opening certain apps on your TV and the settings or menu itself.

These would confirm as whether or not the vertical/ horizontal line issue on Vizio TV is because of your own TV or other apps and input methods.

  • 4. Changing settings

Sometimes TV can glitch and be stuck in a certain loop in one of the picture modes. You can go to Menu and then to picture modes to try out other modes as well. If the other ones work, they are almost a fine fix.

However in some situation switching back to your previous picture mode fixes it too, all you need is to switch to a different one for some time. This is a simple approach so you should definitely try it out.

  • 5. Resetting the TV

As a last method you can try to format your TV. This hard format would remove all the data, apps and saved credentials from your Vizio TV, but if it fixes the issue then it might be worth it.

However you should always have a back up of all the important things before you reset the TV, or anything else.
