Are you experiencing a frustrating issue with your TV where the screen is black, but you can still hear the sound? You’re not alone. This problem can occur on any type of TV, including LED, LCD, OLED, and Smart TVs.

Understanding the Issue
When your TV screen is black, but you have sound, it’s often a sign of a problem with the display or the connection between the TV and the external device. The sound is still working because the audio signal is being processed separately from the video signal. This issue can be caused by a variety of factors, including hardware problems, software glitches, or incorrect settings.
