Problem 1 : the screen one side is darker than the other:

  1. The screen one side is darker than the other.
  2. Try to call out the OSD menu. If one side is darker than the other, it’s a bad T-con board or FPC cable.
  3. If the OSD menu is fine, then checking the LVDS cable and main board . Most of the time is their FPC cable contact pins dirty. After clean the screen problem solved.

Problem 2 : Ghosting image or double image vertically

  1. Ghosting image or double image vertically .
  2. Checking or replace the T-con. Before that, make sure to clean the LVDS and FPC cable contact pins with erase.

Problem 3 : half the screen has a red Solarisation effect

  1. Half the screen has a red solarisation effect.
  2. Red solarisation on the bottom of the screen. Your first impulse is probably to replace the panel, but if you look closely, you will notice that solarisation appears only on the righrt side of the screen. The left side does not show the problem. This tells you it’s not a panel issue. What should you consider? The signal source PCB, or LVDS cable connections.
  3. To see if it’s a signal source issue, enter the service mode and check the test patterns. Notice that service mode, the right side is all red , showing you that the signal source is not the problem.So try to using he strong tape or silicon glue to fix connector and prevent it loose again. So the TV problem was solved.

Most common problems with LED TV Samsung: 

Problem 1 : LED TV screen goes blank

# in the case, most probably the power supply unit inside the led tv has issues .


# the power supply unit is responsible for receiving current and sending it to all the components of the led tv .

# the power supply unit develops issues due to a sudden surge in input supply.

# usually, the capacitor on the power supply boards fail.

# if you disassemble the led tv set, you could verify this by spending a leaking or bulging capacitor.

# these problems are common in modern LED televisions and the repair work is fairly simply and quick.

# it is recommended to find a technician as replacing the capacitor would require soldering skills.

Problem 2 : LED TV has horizontal lines on Start – up

# in this case, the root of the problem is low signal strength in the set – top box cable that is connected to the led tv .

# this problem might not show up if you plug that set – top box to an old television.

# the reason for this is that older tv sets required lower input strength to work.

# with the modern led TVs set it’s not the case.

# they require stronger input signals.

# thus, switching to an HD set – top box will most probably rectify the problem.

Problem 3 : LED TV with no sound output

# disconnect the led tv from the AG power , then press and hold the power button on the led tv ( not the remote ) for 10 seconds.

# after waiting for a minute, connect the tv set back to AG supply and press power button once.

# then try out other “ sound out” from ypur tv to a set of speakers.

# if the speaker work, clearly the internal tv speaker are not working.

# if it does not, it is most likely that the audio IC that drives the internal speakers has failed.

 # it is common in these sets as they use inexpensive low powered amplifier ICs that hear up and fail.

# a simple replacement of the audio IC will do the trick here.

Problem 4 : LED TV not connecting to WiFi

 # The first step is to locate if the problem is in the tv or the router.

# if the tv has no problems in the connecting to your mobile device, then probably the router is at fault.

# try updating the firmware of the router.

# if that doesn’t work, factory reset the router.

# this should do the trick

# you could also borrow a WiFi extender and test if the tv connects to the internet.

# if the signal strength is not the issue consider getting a USB WiFi adapter for the led tv.
