Here are the steps to take to power cycle your Samsung TV.

  1. Switch off your Samsung TV
  2. Unplug it from the power socket and leave it unplugged for 60 seconds (this is very important)
  3. Hold the power button on your TV for about 60 seconds when it’s unplugged.
  4. Switch the TV back on and check if the picture on the screen is now uniformly bright on the screen.

Method 2: Reboot Connected External Devices

Most times, the issue of your Samsung TV top half screen darker can stem from an external device.

By just rebooting these external devices, your problem might be solved.

To check if the problem is coming from an external device like a cable box, simply switch your TV to a different HDMI input source ( for instance, if you are currently on HDMI 1 input, switch to HDMI 2 input).

So, what do you do? Simply reboot it!
