Why is my TV screen black but I can hear it?

Backlight issues: LCD screens use a backlight to light up images displayed on the screen. If the backlight experiences any technical issues, it won't light the display, and the screen will be black, but the user will still hear sound in the background. To fix this problem, TV owners need to repair their backlights.

As backlight failure is a very common issue, this is the first thing to test. To do so, the easiest way is to power on your screen, put a flashlight very close to it and check if you can see the image through. The image would be very dark, like turning the brightness of the screen very very low.

Turn the phone off. Press and hold the following keys at the same time: Volume Down Key + Power/Lock Key on the back of the phone. Release the Power/Lock Key only when the LG logo is displayed, then immediately press and hold the Power/Lock Key again. Release all keys when the Factory hard reset screen is displayed.

This method works on Android devices only, for this, you need your Android phone to be turned off. Simply plug in your USB cable and keep holding down the volume down/volume up button to enter the recovery mode. Here when the menus appear, simply tap exit, and reboot the device.

You can use the TV remote control or TV menu to perform a restart or unplug the TV power cord and plug it back in to perform a power reset.

You can restore all TV settings (excluding the network settings) to their factory defaults. Open Settings, and then select General. Select Reset, enter your PIN (0000 is the default), and then select Reset. To complete the reset, select OK.

Press the Smart button on your remote, then click the Gear icon in the top right, then General > Reset to Initial Settings.

There are lots of root causes for a TV screen going out all of a sudden, but the most popular causes is a failure in the power supply board. Usually, a TV may have more than one power supply boards along with a T-con board as well as other internal parts.
