4. Replacing Your TV Screen

Suppose you find that your Samsung TV Screen flickers on and off, does not show any backlight, gets dimmer over time, or flashes before turning off. In that case, this indicates an issue with the TV screen and the LCD backlight. In this case, you will have to replace your entire Samsung TV screen. 

Repairing your TV screen is usually less expensive than replacing the entire screen. However, if there is a minor issue, like one broken LED light or a crack, you can repair the issue instead of replacing the screen. Look into ‘Samsung TV backlight repair near me to find a reputable professional to do the job. 

However, for more significant fixes, replacing the Samsung TV is best. For small repair jobs, you can expect to pay around $75-$200, including labor.

Suppose you find your Samsung Smart TV backlight continually turns on and off. In that case, there is a troubleshooting fix you can use to prevent this from happening. Owners should do the following steps to turn the Samsung Smart Tv backlight on and keep it on during use:

  1. Turn on the TV power source
  2. Remove the cable connecting the main circuit board and the power to the TV
  3. Reconnect the power source to the TV port

Once you do this, the backlight of the Samsung Smart TV should stay on continually. However, you may find there is no picture, but the light is on. There is no picture on the screen because the main circuit board is disconnected from the screen.

If you find the backlight flickers on and off or doesn’t turn on, there is an issue with the power circuit board. Users should do the following if the backlight stays off:

  1. Disconnect the TV power source
  2. Remove the power cable from the circuit board
  3. Reconnect the TV power source 
  4. Make a note of the power board voltage 

If your voltage is higher than 250 volts, the problem originates from the LED backlights. If the voltage moves up and down, the problem is with the TV power source.

How to Test Samsung LED Backlight?

There are a few easy ways for owners to test a Samsung LED backlight to determine the cause of the issues.

Firstly, view whether your TV is in the Cinema or Custom Picture. This can affect the darkness of the backlight. For example, suppose the screen is still dark after altering the picture quality. In that case, you may need to increase the brightness level under the ‘Picture’ menu. 

Secondly, check if your Samsung LED backlight is using energy-saving measures. If this is the case, you can still override the energy-saving properties and increase the backlight brightness.

  1. Turn the TV on
  2. Click on ‘Settings’
  3. Click on ‘Support’

  5. Click on ‘Self Diagnosis’ 
  6. Click on ‘Picture Test’
  7. Click on ‘OK’ to start the test
  8. Follow the instructions to see if the backlight is the issue
