Why Does My Lcd Tv Screen Go Black?
When your TV goes black, it may be the result of a variety of factors. It could be a problem with the power supply, a faulty cable or component, or an issue with the TV’s software or settings.
One possible cause of a TV going black is a power supply issue. If the power supply is not providing enough power to the TV, the TV will not be able to display a picture. This can be caused by a faulty power supply, a tripped circuit breaker, or a problem with the wiring.

If the TV’s cables are damaged or if the TV’s components are not working, the TV may not be able to display a picture.
