Fixing White Spots on Your Hisense TV: Causes and Solutions

Have you noticed tiny white spots on your Hisense TV screen that become more visible over time? These spots can block the images, making them annoying and disturbing. This article explains why these white spots appear on your Hisense TV and how to fix them.

Why Are There White Spots on My Hisense TV?

White spots on a Hisense TV are usually due to faulty screen components. These components include reflectors, the processor, and pixels. Each part is crucial, so when they fail, it creates visible white spots on your TV screen. Sometimes, turning off the TV’s local dimming feature can also cause white spots.

Causes of White Spots on Hisense TV

Here are the main reasons you might see white spots on your Hisense TV:

1. Fallen Reflectors

One common cause of white spots is fallen reflectors. Your Hisense TV has LED lights with reflectors that help spread light evenly across the screen. If these reflectors come loose due to overheating or poor screen quality, they can create bright white spots.

2. Damaged Processor

A damaged processor can also cause white spots on your TV screen. Overheating or an electrical surge can damage the processor. If you use your TV for long periods without giving it a rest, it might overheat and damage the processor.

3. Dead Pixels

Dead or frozen pixels can create white spots on your TV. Your TV screen has millions of pixels that form images. If some pixels freeze or get damaged, they can cause tiny white spots that become noticeable over time.

4. Local Dimming

Turning off the local dimming feature on your Hisense TV can lead to white spots. Local dimming helps enhance picture quality by adjusting the backlight. If it’s off, it might cause uneven lighting, resulting in white spots.

How to Fix White Spots on Your Hisense TV

To fix white spots, you need to identify and troubleshoot the specific cause. Here are the methods to fix each issue:

1. Fixing Fallen Reflectors

To fix fallen reflectors, you need to take the TV apart. It’s best to contact a professional for this. Opening the TV yourself can void the warranty. However, if you decide to do it yourself, follow these steps:

  • Turn off the TV and unplug it.
  • Unscrew the back panel.
  • Carefully remove the metal tabs and disconnect the speakers.
  • Detach the circuit board and remove the metal plate.
  • Locate the fallen reflectors.
  • Use a cotton swab to apply super glue around the detached area.
  • Reattach the reflector and press it down until it sticks.
  • Reassemble the TV and turn it on to check if the white spots are gone.

2. Fixing a Damaged Processor

For a damaged processor, it’s best to contact a professional. Minor damages can be repaired affordably, but severe damage may require replacing the processor. Adjusting your TV settings can also help reduce the visibility of white spots:

  • Reduce the TV backlight to the lowest level.
  • Lower the overall brightness.
  • Turn off the auto-adjustment feature.
  • Switch all settings to manual.

If these adjustments don’t help, you might need to replace the processor.

3. Fixing Dead Pixels

Fixing dead pixels can be tricky. Sometimes, you can revive frozen pixels by gently pressing on the white spots with a clean microfiber cloth while the TV is off. If the pixels remain unresponsive, the only solution might be to replace the TV.

4. Using Local Dimming

Ensure the local dimming feature is turned on in your TV settings. This can help prevent and reduce white spots caused by uneven lighting.

Cost of Fixing White Spots on Hisense TV

The cost to fix white spots on a Hisense TV ranges from $80 to $170. The price depends on the extent of the damage and whether your TV is still under warranty. Minor issues cost less, while severe damage can be more expensive and might even require replacing the TV.

Lifespan of Hisense TVs

Hisense TVs can last up to ten years with proper maintenance. However, the average lifespan is seven to nine years with daily use. To extend the lifespan, give your TV a rest for four to six hours daily by turning it off.

Are White Spots the Same as Pressure Marks?

White spots are different from pressure marks. Pressure marks result from physical pressure on the TV screen, causing black or white spots that look like bruises or shadows. White spots, however, are caused by issues with the screen components like fallen reflectors or dead pixels.

Conclusion

White spots on your Hisense TV can be annoying, but they are often fixable. By understanding the causes and following the right steps, you can address the issue effectively. If the damage is severe, it might be more cost-effective to replace the TV. Proper maintenance and usage can help prevent such issues and extend the life of your Hisense TV.
