How to Fix a TV with No Picture but Sound

Having your TV go black while you watch can be very annoying. Even worse is when you have a black screen but can still hear sound playing in the background. If this happens, the power button may need to be pressed, or a factory reset may be needed. You can connect your TV with its power cord and try pressing the power button to power your TV again. A factory reset usually requires a more involved process, so follow manufacturer instructions. But these steps may not always work. 

Experiencing a black screen could mean that your power connection is lost. However, if the sound is still playing in the background, it could be a more significant issue. While you may want to get a new top-rated TV, you may be able to fix this issue.

Why is my TV screen Blank?

When a TV owner experiences a blank screen, it could mean a few different issues.

• Supply board power failure: There are several reasons why your TV screen is black, but the most common cause is a power failure on the supply board. Depending on the model, whether it be a budget model or the best 24 inch smart TV, a TV may have more than one supply board together with the T-Con board. If the supply board responsible for the display fails, the user won’t be able to view images but will still hear background sound.
• 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.
• Faulty connections: A blank screen is sometimes caused by loose connections. Check that your cables between devices, power, cable box, and auxiliary devices are tightly fastened. Half the time, television screens have a blank screen, and loose connections are the real culprits. If your TV uses HDMI cables, consider swapping them for new ones. In some cases, you might experience no sound, but you can easily learn how to fix a TV with no sound.
• Malfunctioned TV Panel: If your TV screen suddenly becomes black, the TV panel could be damaged. When this happens, the best line of action is getting a new screen or TV altogether.
• Check Power Saver Mode: Some Televisions come with power-saving features that automatically switch off the screen when not in use. The user will still hear some sound even when the screen goes off. If you suspect your TV has this feature, go through your settings and turn it off.

Fixing a Blank TV Screen

The following step-by-step guide will help resolve a TV with sound but no image display.

STEP 1 Power On the TV

First, power on your TV, don’t use your TV remote; instead, use the button on the TV control panel. You may want to fix the TV remote if it is now working properly. If you can see a menu setting, move to the next step. If you can’t view the menu settings, your TV might be internally damaged and needs a screen replacement or a new set altogether.

STEP 2 Check Cable Connections

Check your cable connections by removing and reconnecting them back. Make sure all the devices are turned on. Inspect the cable wires for any physical damage.

STEP 3 Inspect Other Input Devices

Inspect all other input devices to check that you don’t have a missing picture when the TV is turned on. Check the settings on the device for a switch that might turn outputs on or off.

STEP 4 Replace Cables if Necessary

If you cannot get any pictures, replace the cables between your TV and the input devices.

STEP 5 Try Another Device

Use another device with the same input cables. If you get a picture, your input device might be faulty.
