Hisense televisions rank among the most decent and affordable displays available.
They have screens that deliver good picture quality, among other amazing features.
Despite these qualities of Hisense televisions, some problems usually plague them.
One of these issues is the appearance of white spots on their screens. Having these spots on your Hisense TV can be frustrating and annoying.
You might be wondering what causes them and the solutions to them.
White spots on Hisense TV screens arise from component faults and settings. They can result from fallen reflectors, stuck pixels, damaged processors, or local dimming settings. Fixing these issues will clear the spots off your television screen.
In this article, you will find the reasons for the white spots on your Hisense television.
You will also learn the solutions to them and how to prevent them from spreading.
There is no generic name for the white spots on television screens. You can refer to the issue as white spots or dots on a TV screen.
Some people refer to them as “dead pixels” or “stuck pixels.” This tag stems from the fact that a common cause of the white spots on a TV is damage to the screen’s pixels.
However, the “dead pixel” label limits the reason for the white spots to just damaged pixels.
You can’t use it to describe the issue generally, as other factors also account for the problem.
Reasons for White Spots on a Hisense TV
Faulty internal components are the commonest reasons for white spots on a Hisense television. This issue could also result from one of the TV’s settings.
Let’s look at these causes in detail and possible fixes for them.
#1. Fallen Reflectors
A fallen reflector is the prevailing component issue responsible for white spots on a Hisense TV screen.
Reflectors are lenses in TV panels that cover the LED backlight. They help to amplify and evenly distribute the light across the screen.
When a reflector falls off its position, the light from the LED it covers becomes fixed on the screen. The result of this condition is a bright white spot on the screen.
Fixing this issue involves opening the television case and putting the fallen reflector back in its position.
You may require the service of a professional to do so. However, you can resolve the issue yourself if you wish.
Follow the steps below to take apart your television and fix a fallen reflector:
Unplug your Hisense television and place it face down on a flat surface. Be careful not to scratch the screen.
Remove the screws holding the back cover and take it off. If there is an inner plastic cover, remove it, also.
Disconnect the speakers and the ribbon cables from the panel and circuit board.
Disconnect the IR sensor and remove the TV frame and screen.
Remove the reflector sheets.
Stick the fallen reflector lenses back in their positions. You can use this silicone glue to do so.
Wait for the reflectors to dry, and then reassemble your television.
Note that this is a DIY procedure. If you are unsure of how to go about it, don’t attempt it.
Consult the service of a professional in such cases. Furthermore, taking your Hisense TV apart can void its warranties.
Contact a Hisense service center to fix the problem if your television is still under warranty.
#2. Damaged Processor
Sometimes, a defective processor could be the reason for the white spots on a Hisense TV.
These damages can arise from overheating due to a lack of cooling around the appliance.
Electrical surges can also damage a television’s processor leading to white spots on its screen. In this case, you can adjust the TV settings to rid it of the spots.
These changes include reducing the backlight settings and the television’s brightness. It would help if you also disabled auto adjustments for the settings.
These fixes will work only if the damage to the processor is not severe. In case of extreme damage, you may have to replace the processor.
#3. Stuck Pixels
Pixels light up to produce the images on a television screen. A TV screen contains millions of these picture-forming dots.
The pixels on a television screen can get broken and become stuck in one place.
When these stuck pixels light up, they form white spots on the TV screen. You can fix this problem by reviving the pixel.
Follow the steps below to do so:
Get your materials ready.
Turn off your television. Note the locations of the spots on the screen before you do so.
Let it cool down for about ten minutes.
Use a dry microfiber cloth and gently press the part of the screen where the white spots were.
Turn on the television and check if the spots are still there.
#4. Local Dimming
You can also have white spots on your Hisense TV if its local dimming is off. Turning this setting on will resolve the issue if it is responsible for the spots.
There are other reasons for television white spots that are not as prevalent as the ones above.
The table below contains these causes and the TV type they usually affect:

Some cases of spots on your Hisense TV require you to get a new screen.
This situation is more common when the spots arise from dead pixels which cannot be revived or repaired.
How Do You Prevent White Spots From Spreading on a Hisense TV?
Preventing the spread of white spots on TV screens starts with getting a television free of the spots.
The problem can start even before you buy the appliance. Some televisions suffer spot-inducing damages during transportation.4
Therefore, test one before buying to ensure it is free from this issue. Follow the steps below to test for spots before purchasing a television:
Ask the dealer to turn on the television.
Go to the settings menu and choose a test pattern with a dark hue. If there is none, connect the TV to your phone or any other media source and display a black picture.
You can go ahead and buy the television if there are no spots. Otherwise, select another one.
Addressing the causes is the other way to prevent white spots from spreading on your Hisense TV screen.
When you take the TV apart to restore fallen reflectors, check others to ensure they are not loose.
If they are, secure them with glue to prevent them from falling and causing white spots.
Repair or replace a damaged processor if it is the reason for the white spots.
Leaving it may exacerbate the issue and cause further complications to the television’s components.
Dead or stuck pixels don’t usually spread. If you can’t revive them, it is best to replace the screen.
