Causes Of TV With Sound But No Picture
Some of the causes of your TV screen’s blank, typically black, images are listed below.
Error With Backlight
LCD TVs are particularly affected by this problem since they employ a backlight to illuminate the images on the screen. Consequently, if the backlight has problems, you might not be able to see anything on your screen.
TV Panel Problem
Your TV screen will turn off automatically if the panel is damaged. However, this problem is complicated since you can either buy a new TV or a new screen.
