In a previous article, Mytour guided you on how to fix inverted computer screen issues. In this article, we will outline some reasons behind the blurry, fuzzy, or bleeding laptop screen and provide solutions for users to address the problem.
Fixing Blurry, Hazy, or Bleeding Laptop Screen Issues
Computers play a crucial role in everyday tasks such as studying, working, or researching. However, they are currently facing screen issues like blurriness, haziness, and bleeding.
Several common reasons can help you understand why a laptop screen becomes blurry, hazy, or has bleeding issues.
- Faulty high-voltage backlight of the screen
Typically, high-voltage backlights shine well at 1000 cd/m2. However, when they malfunction, brightness decreases, leading to blurriness, haziness, or marks of bleeding or flickering, causing discomfort to the eyes.
Encountering issues with a laptop screen, experiencing blurriness, haziness, or bleeding, can be a frustrating situation.
- Dimness in the laptop screen due to the high-voltage inverter board
The high-voltage inverter board, also known as LCD inverters, is responsible for generating the voltage needed to illuminate the backlight. When it malfunctions or operates weakly, it affects the backlight, causing the laptop screen to appear dim, sometimes intermittently turning on and off uncontrollably.
- Signal issues from the mainboard
Blurriness, haziness, or bleeding on a laptop screen can also result from uneven or interrupted signals transmitted from the mainboard. It's not only about issues with the screen, connecting cables, or the inverter board; sometimes, the inconsistency in signals from the mainboard contributes to the problem.
- Faulty display cables
Display cables are a major factor causing laptop screens to be blurry, fuzzy, or bleed. These cables typically transmit three main signal sources: 0V, 3.3V, and 5V. When they become loose or faulty, they often lead to display issues such as poor screen visibility, intermittent noise, or inconsistent horizontal-vertical lines. If the cable is cut, you won't receive any screen signal.
The main culprit behind laptop screens appearing blurry, fuzzy, or bleeding is often the primary signal cable.
- Malfunctioning Laptop Screen
After extended use, your computer screen might develop issues, resulting in blurriness, haziness, or bleeding, making it challenging to view.
Resolving Blurry, Fuzzy, or Bleeding Laptop Screen
Unlike the fixable blue screen error, if you're dealing with a blurry, fuzzy, or bleeding laptop screen primarily caused by hardware issues, software interventions won't work. To address this, take your laptop to the warranty service center or reputable computer repair shops for assessment and potential repair if your warranty has expired.
