Depending upon what all components you have connected to your TV, you would find the various cables coming to and going from the TV. Carefully inspect up the cables, not only from the joint area, but even from the other portions. 

If you find any cable damaged, then make sure you replace it. In some cases, removing the cable, straightening out with your hand and again inserting it may also fix up the issue.

If there’s an issue with the connection port, then replace up the port on your TV.¬†

LCDs are less prone to flickering issues as the technology that they function on is a bit advanced. However, even if a LCD TV screen ends up having the flickering problem, there’s nothing to worry about, as the solutions are quite easy to pull off.¬†

We would recommend you to first try the above listed techniques, as those are some ways that are common even for LCD TVs. If they don’t work out for you, then try the following.¬†

Disable Energy Efficiency

If you have enabled energy efficient settings on your TV, then that may lead to flickering on your TV. Why is that so? Well, Energy Efficiency reduces or compresses the functionality of the TV, and if you have components connected that require high energy rates, then those settings may disable them to perform to their optimum level, ultimately leading to flickering on TV. 

Refresh Rate & Room Brightness

A fun fact: LCD screens normally always flicker as the screen updates quite fast, but the naked eye doesn’t catch up to it.¬†

In comparison to the traditional Cathode Ray Tube screens, LCDs have less screen flickering problems. Why is that? Simply, because the latter has a higher update rate. 

Though, if you watch shows on a LCD TV screen under dark lightning, you may find your TV screen flickering. To fix up this issue, all you gotta do is just adjust the room or screen brightness. 

Video Sources Includes Flickering

If the original video source includes flickering then the same is going to project on your LCD TV. It doesn’t matter what the video source is, whether a live event or a recording, if it includes the flicker images, then there’s nothing much you can do, other than just replacing the video source.¬†

Internal Connection Issues

If there’s an internal issue, then it’s a sign that the internal components need to get fixed up at the earliest, and in worst cases, if needed you may have to even end up replacing TV.¬†

Remove the Screw:

  • There would be wires connecting the plastic panel to the TV. Out of that, the leftmost wire/circuit has to be disabled.

Replace LEDs

It isn’t very hard to replace the LEDs, however, it isn’t that easy too. In the process, you may even end up damaging the TV panel, and unfortunately, the TV panel isn’t repairable.

Replace T-con board, Main board & TV panel

If nothing from the above seems to fix the flickering issue, then it’s time to go the extra mile on how to fix a flickering TV screen.¬†

You can try individually replacing the Main board and T-con board. If the problem still persists, then there are high chances that the problem is with your TV panel only. 

As already said above, TV panels aren’t repairable, and therefore, you will have to get it replaced only.
