If you’re getting a black screen on your Sony TV, we’ve got you covered right here.

Even the best Sony TVs can encounter this type of issue, and there are some common causes for it and thankfully, some steps you can take to solve it…in most cases that is.

Here’s our step-by-step guide to getting your Sony TV working again.

Sony TV black screen common causes

Faulty HDMI cable

HDMI cables transfer high-definition video from one device to another. If a TV shows a black screen while you’re using an HDMI connection, it could mean you’re using a faulty HDMI or port to transfer a signal. 

LED backlight issues

Sometimes the TV’s backlight gets damaged by a sudden surge in electricity or power loss. You can easily identify backlighting issues by flashing a light on the TV screen and seeing if pictures are clearly visible. If not, it means you will need a new light to see pictures. 

Faulty connected devices 

Faulty devices often cause black screen issues. If connected devices aren’t working properly, it can cause input issues.  

Software glitches

Sometimes, software glitches can cause the Sony TV to malfunction. A variety of issues, from corrupted system files to conflicting applications or third-party apps, might lead to a black screen. 

Issues with the remote control

Problems with the Sony TV remote control can also mimic a black screen issue. If the remote isn’t working correctly, you might not be able to navigate the Sony TV’s interface. This can make it seem like the device isn’t functioning when, in fact, it’s an input problem rather than a display problem.

How to fix Sony TV black screen

Step

1

Check HDMI cable and ports

If your device has black screen issues, the first thing you should do is check the HDMI cable. Plug out and plug in HDMI from both devices to identify if the black screen issue is caused by a loose cable. If the HDMI cable is damaged, replace it with a new HDMI and check if the screen gets back to its original condition. 

If it doesn’t work, the problem might rest in the HDMI port, try changing the HDMI port and reconnecting the streaming device and Sony TV.

Step

2

Switch off power-saver and sleep timer

Many users have suggested that turning off the Sleep Timer (Idle TV Standby) and Power Saver immediately fixes the black screen issue. 

To turn off the Power Saver Mode, press the ‘Home” button from the Remote and find ‘Settings’ (Most Android & Google TV offers Settings Menu in the top right corner with a Setting Icon),  once you are in the settings menu press System, then Power and Energy, Find Energy Saver and then press on Power saving. You’ll be greeted with three options; High, Low, and Off. Press Off to disable Power Saver. Some TV models include a Settings Button directly on the remote control. Check your remote to ensure. 

To disable Sleep Timer, follow the below methods;  

  • Press the Home Button From the remote control
  • Select device Preference, then Power option
  • Find Idle TV Standby and turn it off

If it doesn’t work, the problem might rest in the HDMI port, try changing the HDMI port and reconnecting the streaming device and Sony TV.

Step

Check power cords and voltage supply

Check Power cords aren’t loose and firmly connected to both devices. Ensure that the TV gets enough voltage supply continuously to display images. Look for any visible signs such as kinks, burns, or damage, if you found and replace them with a new power cord. 

Use the power cycle (soft reset) method if the issue isn’t resolved. Unplug the power cord and wait for at least 60 seconds to plug it again. After reconnection turn on the device and check if the issue has been resolved.

Reset the TV

Using TV Buttons

  • Unplug the power cord
  • Locate the power button and volume button on the TV, press and hold them together, and plug the power cord while holding them. Hold them until a green LED light appears along with the Sony TV logo. Sometimes it can take 10 seconds for the green LED light to appear sometimes it will take up to 30 seconds. 
  • Then the TV will restart and a welcome screen will appear. It indicates your TV has been reset. 

Using Remote Control 

  • Press the ‘Home’ Button, go to settings then ‘Storage & Reset’. You’ll find the ‘Factory data reset’ option, pressing on it will warn you to ‘Erase everything’, so press Yes to Reset. 

Step

5

Update firmware

Updating the TV can fix black screen issues if it caused by software glitches or app crashes. To check for updates, go to Settings, then System, look for the About option, and press on it. There will be a System Software update available, turn on the Automatically check for updates settings. And the TV’s OS will update automatically. 

Step

6

Turn off presence sensor

Some Sony TV models are equipped with a Presence Sensor that reduces power consumption and automatically switches off the TV when no one is watching. When you approach the TV, if it doesn’t switch back on, the sensor might prevent it. To turn off the Presence Sensor, get a remote control and press the home button, Find Settings, select Preferences, and press Eco. It will show the option to Switch On and Off Presence Sensor, and turn it off.

Contact customer support

If you’re unable to resolve the issue yourself, it may be time to seek help from a professional technician or customer support. Take your device to a certified repair technician. They can perform a detailed diagnosis and recommend solutions.
