How to Hard Reset Sony Bravia Tv Without Remote

If you're having vertical lines on Sony Bravia TV screen, you've come to the right place to learn the solution!

Vertical lines could either mean there are power interruptions with your TV or an issue with the display, but we will provide you with the best solutions against these issues!

If you're having vertical lines on your Sony TV screen, check the HDMI and power adapter. Then disconnect ALL third-party devices connected to your TV and perform a restart. Lastly, you can update your TV and if it does not work, perform a factory reset.

Before we jump into the troubleshooting process, let's first take a look at what could be causing the issue in the first place.

Why Are There Vertical Lines On Side Of Sony Bravia TV Screen?

Since vertical lines on the side of your screen are quite unusual, you must first consider whether you have damaged the screen or not.

If one pixel goes black and light is no longer shined through it, the whole row of pixels will become black as well. This is what we call vertical line and could happen with any TV over time.

If we exclude the hardware problem here are the causes that you're left with:

1. Technical Problem

Vertical lines on the side, middle, or bottom of your TV, most often identify as a technical issue.

2. Input

It is possible that the issue is bound within the inputs and source of your Sony TV.

3. Third-Party Device

A third-party device broadcasted to your Sony TV' screen could also appear as a vertical line.

4. Cable Issue

A fault with the HDMI or even power adapter sometimes might also cause abnormality in your Sony TV screen.

5. Broadcast Issues

Lastly, if only the broadcast you're enjoying on your TV is having these vertical lines, the issue might be from the source and on your side.

Now that we've taken a look at the situation and you have a better idea of what's going on, let's proceed with the solutions on how to fix the issue.

How To Fix Sony Bravia TV Vertical Lines On Screen?

Before we proceed, make sure you have restarted your TV to determine if the issue is a temporal glitch or something like that.

Although we assume you have already tried that, it is recommended to restart all over again before applying any troubleshooting.

If a restart didn't work and the vertical lines are still there, try some of these workarounds:

Solution #1 Switch To A Different Channel/Broadcast

If the issue is within the channel/broadcast you're currently watching on your Sony Bravia TV, we recommend switching to another source of the video.

Vertical lines might often occur even when your TV is not faulty, so try changing the broadcast or the source in case you're using any 3rd party device to broadcast from.

We recommend using channels and not third-party devices connected to your TV since channels are the most proven way to check your TV' screen.

Try some of the most famous channels on your subscription, since the chance for them to have vertical lines is very little.

Solution #2 Discharge Your Sony TV

Another way of fixing the issue is through a hard reset, also called the power cycle by the users.

This process will actively discharge your Sony TV out of any remaining electricity, thus, fixing any temporal power glitches that could be causing the vertical lines you're seeing.

Here is how to discharge your Sony TV appropriately:

1. Turn OFF your TV through the hardware Sony remote.
2. Unplug the TV's power adapter and wait for ~5 minutes.
3. Once 5 minutes have elapsed, re-attach the power adapter and run your TV.
4. Test.

If the vertical lines are still there, we recommend using another source of power income for your TV, since the current one could have developed issues.

Solution #3 Reconnect The Cables

First of all, vertical lines could be actively caused by an inappropriately attached HDMI cable or power adapter.

For this solution, we suggest you go through all cable connections of your TV and all third-party devices attached to it.

Make sure everything is positioned correctly and no loose or faulty connections are detected.

In addition to this, check the cables for ripped parts or visual hardware damage and replace the faulty ones as quickly as possible.

At last, you should double-check that no cables are in an unnatural position, or in a twisted position.

Solution #4 Change The Input

If vertical lines on Sony Bravia TV screen are still there and you're not using your Sony TV to watch any channels, the issue might be appearing from third-party sources or devices connected to it.

It is possible that the vertical lines are occurring due to faults in those third-party devices.

For this solution, we suggest you change the input (source) of your TV.

Here is how to change the input on your Sony TV:

1. Go to the menu of your Sony TV and access the settings.

1. Open the source menu of Sony.
2. Choose a different input or the default input.
3. Confirm the default input and test your Sony TV-out.

It may take your Sony TV a couple of minutes to stabilize and afterward, the vertical lines should disappear.

Remember to test on "Watch TV" or simple channels instead of applications or other devices.

Solution #5 Update Your Sony TV

With newer updates of Sony, the picture would get many upgrades that will deal with glitches such as the vertical lines issue.

For this solution, we recommend updating your Sony TV to the latest available version.

Here is how to update your Sony TV:

1. Go to the Settings.
2. Access the Customer support tab and tap on Product support.
3. Select Software Update and skip the next step that requires network confirmation (If your Sony is already connected to WiFi, skip the network step).
4. Select yes and confirm the new software installation.

Based on your TV's performance, the process may take up to 5 minutes and during that time, your TV's power flow must not be compromised to avoid further software issues.

Once the update is done, your TV will perform a restart, and afterward, the vertical lines should be gone.

Solution #6 Reset Picture/Display Settings

Sometimes if you're using a bad configuration of your picture settings, the vertical lines could be a result of any of your previous changes.

In that regard, it is best to reset them to default, and here is how:

1. Go to Picture and Display Settings.
2. Choose Advanced Settings.
3. At the bottom click on Reset.

This process should revert ALL display and picture settings to default, thus excluding the possibility of a bad setting that could be causing the vertical lines.

If that does not help, then it might be an internal software issue so let's proceed with factory resetting your Sony Bravia TV.

Solution #7 Factory Reset Your TV

Before wrapping things up, we suggest performing a factory reset on your TV in an attempt to fix the vertical lines.

If the issue is occurring due to a software glitch or malfunction, a factory reset might be able to resolve the problem for you.

Here is how to factory reset your Sony Bravia TV:

1. Go to the settings of your Sony TV by pressing the Home button.
2. Go to Device preferences and tap on Reset.
3. Select Factory data reset and input a PIN code if you've created one. (PIN codes are not created by default)
4. Confirm and wait.

Like with the update, your TV will also perform a restart here and the power flow of the device must remain intact during that time.

In case the problem appears even after a factory reset then you should start suspecting the display itself as a hardware piece.

You might want to contact Sony support for one last inspection before you proceed with purchasing a repair.
