If you are trying to find a way to fix a half-black screen on a Samsung TV, there are several helpful ways you can return your TV to its initial state. The half-black screen problem on Samsung TVs is annoying and, unfortunately, can cause problems. If the problem is with the backlight, it needs to be replaced. There are many different causes of a half-black screen. They include physical damage, software problems, cable connections, LED strip failure, display panel failure, and T-Con board failure. While this may not be the most ordinary crisis, it can occur for a variety of causes, including hardware problems, loose connections, software glitches, and external device compatibility issues. This can be very frustrating and difficult to know how to fix.
What is the cause of the black screen issue on my Samsung TV?
The most common cause of a black screen on a Samsung Smart TV is that there is no signal coming from the original appliance (e.g., line box or satellite receiver). If you are utilizing an HDMI cable to attach your Samsung Smart TV to a cable box or satellite receiver, make sure the cable television or satellite receiver is bound to the proper dock on the back of the TV. If you are utilizing an optical association, such as an RCA cable, make sure the RCA cable is attached to the proper harbor on the back of the TV.
10 Helpful Methods
1. Turn the TV Back On
If your Samsung TV has a dark shadow on one side, the first thing you need to do is turn it back on. If it is due to a software glitch, this will fix the problem. Otherwise, it does not apply to you.
Here is how to turn the TV back on

2. Tap the TV Bezel
The old-fashioned method of tapping to fix the problem still works. I fixed a Samsung TV with a half-black screen by simply tapping around the problematic rear/side bezel half of the screen. Many users also reported that doing the same thing fixed the problem. So, tap on the black bezel or side bezel on the side where the black screen effect is occurring whether it is the top half, bottom half, right side, or left side of the screen, and tap on it. If this works (even if you have your doubts), leave a comment below.
