In this article, I will address your query, “How to fix TV has sound but no picture?”
Reasons for a Black or Blank TV Screen
There might be several reasons why your TV screen is blank. They are,
1. Power Supply Board Failure
The most common cause of a blank screen is a problem with the TV’s power connection circuit.
T-con boards and similar interior parts are often located next to the power supply board.
Check your television with a different power source to confirm that the issue is with the power supply. The problem is solved by employing the power outlet rather than the TV.
2. Backlight Error
LCD TVs face this problem because they consist of a backlight. In case the backlight fails, you might not be able to watch any content on display.
3. TV Panel Issue
A broken TV panel will always lead to a blank screen. Nevertheless, two remedies exist for this problem: either buy a new TV or a new display.
4. Sleep Timer
In case the sleep timer is set, the TV may sleep automatically after the timer expires. It’s useful to know that you may cancel the timer in your TV’s configuration menu.
5. Bad Connections
The television screen might go black for a number of causes, including faulty connections as well as wiring.
Inspect the cords and the power supply to confirm that your TV is rightly connected.
6. Capacitor Issue
In case the capacitor fails, the screen won’t be equipped to display pictures or turn on.
7. Power Saver Mode
Several televisions include power-saving technologies that turn off the display while not in use. Although the screen is turned off, the viewer will continue to perceive some sound.
If you believe your television has this function, go into the settings and disable it.
