Sony TV black screen – how to fix, causes, and step-by-step guide

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.

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.

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. 

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. 

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. 

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. 

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.
