• Improper power supply
• TV heating
• Short-lived TV/app problems
• TV heating
• Wrong picture settings
• Firmware-related issues
• Damaged TV screen or hardware

The above-mentioned are the common reasons why you are having your Hisense TV flicker. Below, I have elaborated on them and clearly given their respective fixes.

Issues in TV Connection/Cables

The connection discrepancy is the primary factor in most scenarios of Hisense TV flickering issues. Don’t forget that this issue arises not only because of faults in your TV’s connection but also because of other devices linked to it.

Solution

As a foremost troubleshooting step, go to your Hisense TV’s rear side and push its cable firmly into the power outlet. If you intend to use a streaming device/stick, cross-check that there is no loose contact between its HDMI cable/connector and Hisense TV’s HDMI port.

If you are a cable or satellite service user, TV channels load immediately when you turn on your Hisense TV. A flickering effect will be displayed if your old model Hisense TV can’t pick up channels. Confirm this by accessing any menu or settings. If they work fine, then there is nothing technically wrong with the TV. You can perform a channel scan on Hisense TV to load channels and get rid of its screen flickering issue.

If you don’t have the above scenarios, you have to look into the cables. If the cable of your TV or streaming device is damaged, it can’t transmit video signals properly to the screen. Thus, your Hisense TV will be flickering on and off. So, inspect it thoroughly and repair or replace it if damaged.

Sometimes, Hisense TV, which is wall-mounted or connected to power strips, is reported to be showing problems like showing horizontal lines on screen or blinking on and off. If your Hisense TV is connected in any of these ways, better place it on a table and connect it directly to a wall power socket. Either of these measures will work for you, and there’s a chance for you to be out of Hisense TV screen problems.

Problems with HDMI Port

The condition of your TV’s HDMI ports should also be good for normal video signal communication from connected streaming. If the respective port has errors, problems like flickering or a black screen will arise.

Solution

While checking the cables, review the HDMI ports of your Hisense TV also. If its interior has any debris or dust, clear it immediately. Suppose the port is damaged or deformed, connect the HDMI cable to another HDMI port and continue watching the TV until the impaired HDMI port is repaired.

Improper Power Supply

There is a chance of insufficient power supply if your Hisense TV blinks on and off. If you keep the TV running in such circumstances, then it will catch up with serious internal damage to minute parts and stop working permanently.

Solution

Take a tester and check whether all the slots of your power outlets have a power supply. If any of them are not working or the outlet is clearly damaged, you have to repair it to use your Hisense TV with it. Until then, you can reposition your Hisense TV to another location where a finely working power socket is present and start using it.

If your whole home experiences power fluctuations, immediately turn off your Hisense TV. Contact an electrician and call them up to fix the voltage problems. You should turn on and access your Hisense TV strictly after doing so.

Short-lived TV/App Problems

Sometimes, the reason for your Hisense TV screen flickering is not as serious as you think. Temporary bug attacks or unexplainable errors might have occurred on your TV. Sometimes, the channel or app you are currently watching on your Hisense TV could have crashed.

Solution

First, restart your Hisense TV by turning it off and on. This will flush out the troubling corrupted bugs and cache files and return your TV to its normal state. If this doesn’t work, see whether you can navigate the TV’s on-screen options by managing the screen flickering. If it is possible, head to the Settings option and clear the cache data on your Hisense TV. The cache is the factor next to the faulty connections that is expected to favor Hisense TV flickering issues.

Likewise, if the app or channel you are streaming experiences a crash, your Hisense TV screen will flicker. But remember, this doesn’t count as your TV’s issue. So, exit your current app and check if the TV screen flickering happens on the other screens or apps as well. If not, uninstall the app from Hisense TV since it could have attracted problematic agents. If you wish, you can install the app on your Hisense TV from its native app store for later usage.

When the problem occurs while watching a TV network, change to another channel and see if the same problem prevails. If not, then that particular channel is crashed, and all you can do is wait until the channel provider rectifies it.

TV Heating

If your Hisense TV’s connection, cables, power outlet, and port are all fine, the flickering may be due to heat issues. This is not a very concerning factor but definitely requires your timely attention.

Solution

Touch your Hisense TV unit on the backside. If you can feel extreme heat, immediately turn off the TV. Remove the TV’s cord from the power socket. Leave it as it is for about 15 to 20 minutes and let it cool down. Then, touch your Hisense TV again and see if its temperature is normal. If yes, you can make the connections again and expect the Hisense TV flickering issue to be sorted out after this power cycle.

Wrong Picture Settings

Your Hisense TV viewing can be optimal only with appropriate picture settings. If you have made the wrong selections, you will experience unpleasant viewing or problems such as flickering or flashing.

Solution

If the flickering is moderate and adaptable, manage to go to the picture settings option on your Hisense TV. See if the Dynamic contrast is turned on. If it is so, disable it. This option will make your TV screen change between bright and dim instantly according to the color of the content that’s running, which looks like flickering, but actually, it is not.

Similarly, try turning off the ECO Lighting and Energy saver mode on your Hisense TV and see if it helps stop your Hisense TV from flickering.

Firmware-related Issues

Outdated firmware is an extreme factor in your Hisense TV flickering, if not hardware-related damage. Malware attacks might have also occurred and landed you in this problem.

Solution

If you have analyzed all the above-mentioned reasons for Hisense TV flickering and none of them matches yours, then it is the issue from the end of the software. You either have to update your Hisense TV or reset it completely to find a remedy. In your scenario, it would be tough to access your Hisense TV options with screen problems and perform firmware upgrades. But if the screen is quite okay to access, you can give it a try.

Otherwise, locate the Reset button at the unit’s backside and hold it for a while to factory reset your Hisense TV. Once the reset is over, set up your Hisense TV and use it without flickering issues.

Damaged TV Screen or Hardware

Now, you could have realized that your Hisense TV has some serious hardware-related issues and, as a result, had its screen flickering. These cannot be rectified by DIY troubleshooting methods and need expert handling.

Solution

Carefully analyze the TV screen. You could notice any cracks, breakage, pressure spots, or horizontal/vertical lines on the Hisense TV screen. If nothing like that is present, then the essential internal components like the T-con board, picture tube, backlight, or TV bulb should be damaged.

In such cases, you can take your TV to the nearby service center for repair. You can also directly contact the Hisense TV support service [Phone number: +1 (888) 935-8880, email address: [email protected]]. They’ll send you the respective authorities and take your TV to repair to their place. Or else, they’ll provide you with the instructions to pack the TV and send it to them.

Suppose your TV screen is beyond repair; you have to replace it. The Hisense TV screen replacement cost varies for each model and region. So, have a word with the support agents before screen replacement and confirm the charges.
