How To Fix A Sony TV Screen That Randomly Goes Black

If your Sony TV screen suddenly went black while watching your favorite show, you can hold your peace.

We have provided you with ways to solve it, and you can be sure none will take your hours.

Fix #1: Turn Off the Power-Saving Mode

When the power-saving mode is on, your Sony TV will go on standby mode.

Hence, the screen will appear black, and you will probably hear a sound. You will need to turn off this mode.

These steps can help.

1. Using your Sony TV remote, access the Home menu.
2. Click on system settings.    
3. Select Eco, then click to turn it off.

If your device is Sony Android, you will need to go to the home menu followed by Settings, Power, then turn off the Eco mode.

Power off and on your TV, and check if the problem is resolved. If not, go to the next step.

Fix #2: Turn Off the Sleep Timer

Just like the eco mode causes your TV to go on a standby mode, so do sleep timers.

You may need to turn it off because probably someone set it on without you knowing.

Here is how you can do it on your non-Android Sony TV.

1. Press the Home on your TV’s remote
2. Click System settings
3. Select Timers or clock, and turn it off

If you are using an Android Sony TV, click the Home button, select settings, then date and time. Choose automatic date and time, then turn it off.

When the sleep timer is on, your TV goes off after some intervals. Put on your TV to see if it still behaves that way. If so, keep on reading and trying.

Fix #3: Turn Off the Demo Mode

When the demo mode is on, it limits some functionality of your TV. Retailers use this feature to display how your TV functions.

However, it causes issues like your TV turning off randomly. So, you may need to disable it or turn it off.

Here we go.

1. Use your remote to go to Home.
2. Select settings.
3. Select Device preferences followed by Retail mode settings.
4. Locate picture reset and demo modes and set them off.

Check again if there is any change on your device. If not, do not get tired; let us keep going.

Fix #4: Check the HDMI Port

Your HDMI port may have spoiled. You can check if it is so by trying a different HDMI port.

Unplug your TV’s HDMI cable and plug it into a different input. Check if the problem goes away.

Fix #5: Change the HDMI Cable

If you have tried plugging your HDMI cable into a different port but your TV black screen issue is still there, the problem might be your cable. It might be faulty or has a short.

You may need to replace it with a brand new cable. It should also be a high-speed cable, such as HDMI 2.0. 

Plug the cable into its input port to check if the black screen issue goes away.

Fix #6: Check Your Remote Control

If your remote has an issue, it can also cause a black screen. Probably, there is a place that you might be clicking without your knowledge, causing the screen to turn black.

The remote might also be having stuck buttons that click themselves.

Remove the batteries from your remote, then control your TV manually.

Power off and on the TV, then wait for a while to see if the issue is still there. If the issue disappears, then your remote is the cause of the problem.

Replace the remote’s batteries, and you will say goodbye to random black screens.

Fix #7: Check External Devices

External devices include USB, antenna, HDMI, LAN, etc., apart from the AC adaptor cord.

Remove these devices and check if the issue resolves. If so, return each device one by one until you reach the one that causes the TV to go black.

I know this process is cumbersome. But if it solves the issue, then why complain. Kindly try it out.

Fix #8: Power Reset The TV

Power resetting, unlike factory resetting, only reboots your device without restoring it to default settings.

So, you may not need to worry that you will lose your TV settings. It can also solve your black screen issues. Let us see how you can power reset your Sony TV.

Press your TV remote and hold it for about 5 seconds. Your TV will then restart, but you will see a shutting down message on the screen.

Some models will also give you the restart option on the screen. So, you may only need to click it to restart your device. Your TV will then shut down then restart after about one minute.

Fix #9: Update Your TV’s Firmware

Ensure that you turn on this feature always to get the latest software updates.
