Tv screen goes black but sound still works. If your smart tv screen goes black, but the sound is still coming, then it means the tv is working and something is going wrong suddenly.
Smart devices are not exceptional from technical errors, so if you are disturbed by the issue, then read this complete article to learn why the tv screen goes black, but the audio still works.
You can not relate that your smart tv power cable is disconnected from the wall outlet because the sound is still coming from the device.
Power saver mode
Power save mode is another reason the tv screen goes black. So, check your tv settings and disable the power save mode on your tv.
Power saver mode is installed in some devices to save energy, so if you don’t want to disturb it again and again with a blank screen, then disable the power saver mode from the tv settings.
Check cable connections
When you install your smart tv on the wall, make sure to tighten the cable connections because if there is any loose cable, the tv screen will go black, but the sound is still coming.
If your tv device is old and you have been watching it for a long time, then its HDMI cables and power cables might be damaged or may have become loose in the ports, due to which the tv screen goes black.
Check Power Supply Board
The power supply board is the most important component of the smart tv because it transfers the power supply to different components to work.
If the power supply board is damaged due to a power surge, then tv screen display issues generate. If the power supply board becomes faulty, then you have only the option to replace the power supply board.
I suggest you don’t try this step on your own because there is a very complex system in the tv so hiring a professional tv technician is best for you to replace the faulty board.
