Inspect Your Connections
If all these drastic measures do not solve the issue, consider checking connected cables for loose connections.
A flickering TV screen is often a result of loose or incorrect connections between the input device and the TV.
Ensure that all connections are firmly secure in the correct ports to stop your TV screen from flickering.
Also, check the ports for clogs and swap your cables accordingly to restore your display.
Replace Faulty Cables
The latest TVs and media players use HDMI cables as the standard video and audio connections.
As much as these cables deliver quality sounds and pictures, they are still prone to defects and malfunctions.
Faulty cables and defective ports can cause your TV screen to flicker unexpectedly and persistently, leaving you frustrated.
Start by testing your cables with different devices to separate the defective ones from the functional ones.
You can disconnect everything and plug them in one by one to find faulty cables.
If you find faulty cables, replace them immediately to stop your TV screen from flickering randomly.
Signs of a Damaged HDMI Cable
Check the Input Source
Sometimes your TV screen might flicker because of a defective set-top box, soundbar, or DVD player.
All the cables may be firmly secure in the appropriate ports, but your TV still flickers because the input source is defective.
If you have another TV, you can test your input source to ascertain that it is the cause of the problem.
If your input source is unrepairable, you may have no other option but to replace it with a functioning one.
Adjust Your Antenna
Unbelievably, a flickering TV screen may result from weak broadcast signals.
If you use an over-the-air antenna to watch local channels, your TV might flicker because of poor reception.
Adjusting your antenna to face the direction of the broadcast towers can help resolve the issue.
You can also consider installing a signal amplifier or booster to enhance the broadcast reception.

Consult a Technician
If you’ve tried everything but nothing seems to work, do not open the TV casing but instead consider calling a technician.
Like any other electrical device, opening the TV yourself for diagnosis can be dangerous due to the risk of electric shock.
A professional can inspect your TV to determine whether the issue is caused by hardware failures.
If most of the components are damaged and irreplaceable, start saving for a new television to avoid further disappointments.
