TV screen flickering? Here are some possible reasons why

Whether you’re the proud owner of an ultra HD QLED TV or are dealing with a 43-inch not-so-smart television, flickering of the screen could happen to just about anyone. And much to our disdain, it often ends up interrupting our beloved TV shows and is certainly hard to ignore. But before it turns into a persistent problem or, worse, begins to give you a headache, there are multiple things you can do to rule out minor issues.

5 reasons why your TV screen could be flickering

Several factors could be contributing to the flickering issue in your television screen. However, there are measures you can take to ensure these issues are ruled out right before they turn into a persisting problem. Below, we’ve listed a few possible reasons along with their solutions; read on to find out more about them:

1. Loose cable
2. Dust and debris build-up
3. Outdated software or firmware
4. Overheating TV
5. Refresh rate issue

1. Loose cable

If your fairly new television begins showing signs of a flickering screen, rushing to a service centre may seem like a regular panic response. However, before you do, it is important to note that loose cords and cables are the first culprits when it comes to an issue with the screen. Make sure the cables are plugged in properly. It is best to unplug your television, wipe the cables clean and replug them into your TV. If the issue still persists, check the cables for any damage before showing your TV to a trained technician.

2. Dust and debris build-up

If you reside in a dust-prone area, dust or debris build-up can cause electricals to malfunction. As a result, you might witness flickering or glitches on your screen. Regularly wiping not only your TV’s screen but also the wires could help prevent this issue.

3. Outdated software or firmware

Like other gadgets, your television also requires software and firmware updates from time to time. Old or outdated versions could cause your television screen to flicker due to bugs. Check the Settings panel on your TV for software updates. Updating to the latest version could help solve your television’s flickering issue.

4. Overheating TV

Using your television for extended periods can cause it to overheat can cause ghost spots on its screen. A more serious issue, like the internal fan failing, could also be a cause of its overheating. In this case, the TV has to work extra hard, causing the screen to flicker. It is best to switch off your TV and let it cool down before switching it back on again.

5. Refresh rate issue

Perhaps the most common out of the five, the refresh rate of your TV can often be a leading cause for the screen to flicker. Your TV’s refresh rate measures how often it will change the picture on your screen. The higher the refresh rate, the more the number of pictures displayed on your screen.

It is best to ensure your TV is compatible with the refresh rate being used for it. Within your television’s Display Settings or Picture Options, you will find the option to choose between different refresh rates. However, it is crucial to note that the availability of this option will differ from brand to brand. 

A lot of the time, a flickering issue on your TV is nothing to worry about. But in case you find it cropping up, despite fixing it every now and then, getting it serviced could help you prevent a much larger problem in the long run.
