Method #2 Check If Your HDMI Port Is Working
If your HDMI cable is working correctly, it is time to see if this black screen flickering is the TV’s fault.
Most of the time, at older TVs, HDMI ports could start interrupting the signal which could also result in the annoying flickering you are experiencing.
In such cases, there are a few ways you could determine whether it’s the port’s fault or not.
Most of the newly released TVs have 3 HDMI slots located on the back bottom of the TV and one HDMI located on the side of the TV.
In order to see all of the HDMI ports as well as all other inputs, head to the “Sources” option. You can find this option by pressing the Home button on your TV and navigating to Sources.
Simply check if your TV has more than one HDMI slot available, if it does, try unplugging your HDMI cable from the current port and plugging it into another slot located on your TV.
Once done check if the issue is resolved.
If this doesn’t help, you might reconsider grabbing a new HDMI cable for your TV in order to get the HDMI connection blinking issue resolved.
Method #3 Check HDMI Connectivity
A casual mistake when using an HDMI cable is to not plug it all the way in, which eventually results in very bad signal interruptions and sometimes no signal at all.
Make sure to check if your HDMI cable is fitted perfectly in the operational HDMI port.
Keep in mind that if you push your HDMI cable in the slot too hard, it might result in the disintegration of both an HDMI cable and port, so remember to be gentle upon plugging HDMI cables into your TV.
Also, make sure that the cable is not being under pressure and straighten the cable as much as possible.
Method #4 Check for Internal Connection Problems
Keep in mind that this annoying flickering could also be caused by a loose or failing connection located inside the TV set itself.
Such an issue could only be resolved by an experienced technician.
This flickering will constantly happen, regardless of the HDMI cable and such issues often indicate that the TV you are using could be near death.
Of course, such issues are rare to occur, and if you still have an intact warranty, it should be able to cover it entirely.
If you decide to troubleshoot this issue by yourself and open the TV’s panel, their warranty will be instantly voided.
HDMI Connection Flickering on LCD TV
Luckily there is a solution you can try that only works on LCD TV.
So, if you’re using one and you’re experiencing flickering with HDMI, do not hesitate to apply the below-described method.
LCD screened TVs are always flickering, but human eyes aren’t able to see fast enough to spot it because the screen updates really fast.
TVs that are using LCD screens are much less likely to be interrupted by screen flickering than older ones that are using Ray Tube or CRT, just because the LCD screens are having a higher refresh or update rate.
However, if you are currently observing the LCD screen under a very dark or very bright environment, you may be able to notice the LCD screen’s black flickering.
Adjusting the screen’s brightness or the room lighting itself could eventually resolve this issue.
HDMI Flickering on TV Is Still There…
If none of the above-listed methods seem to resolve your issue, there are some alternative options for you to try.
If the issue persists after you have applied all of these steps above, your problem might be more complex and require technical support from the manufacturer team.
Contacting your TV’s technical support is always recommended.
Even if they don’t accept your TV for repairment they might give you some helpful tips on how to troubleshoot the issue.
