Compilation of Common LCD Screen Error Fixes
1. Screen flickering and unstable flashing.
Screen flickering has numerous causes and is a frequent issue on LCD screens. To specifically address this issue, we must investigate the cause of each problem and attempt troubleshooting from simple to complex solutions.
- Firstly, screen flickering on LCD screens may be due to incorrect screen refresh rate. Although this issue rarely occurs, it is not impossible. Typically, screens have a stable frequency of 60 Hz, but with newer screens, the frequency may be higher, even up to 144 Hz. You need to check and set your screen according to the correct standard.
Step 1: Begin by right-clicking anywhere on the desktop screen and select Graphics Properties.
Step 2: Next, the Graphics Properties menu will appear, proceed to choose Display.
Step 3: Within Display, simply set the screen to 60 Hz (typically 60 Hz) by clicking on Refresh Rate and selecting 60p Hz.
- The faulty monitor cable can also potentially lead to the problem of a jerky LCD screen. Whether it's a laptop or desktop, over time, the monitor cable may wear out, have poor contact pins, or become damaged due to impact. If on a desktop computer, simply remove the cable and replace it with a new one. However, if you're dealing with a laptop, you'll need to take it to a repair shop to diagnose and fix this common LCD screen issue.
- If it's not the Cable, it could also be the VGA itself causing issues, including both VGA port and Chip inside having problems. The port may suffer from oxidation while the Chip inside could be due to usage errors, overheating, or improper cleaning. In such cases, the only solution is to take them to authorized service centers for repair.
- The ultimate cause leading to a jerky LCD screen could also be due to the screen itself being faulty due to external impacts such as hard objects colliding or dropping. And there's no other way to fix it than to take it to authorized service centers for repair.
2. Color bleeding on the screen
Color bleeding on the screen is quite common on older monitors and has various causes. However, it mainly focuses on 2 issues: the screen and graphics VGA.
- Graphics VGA malfunction is the primary cause of color bleeding on the display. This color bleeding could be just a single line or even a large area. It's a problem that can't be fixed on your own. If it's just a single line, you might be able to tolerate it, but if these lines are causing too much hindrance, you'll need to get it repaired immediately.
- Another common issue on LCD screens is caused by external impacts or prolonged usage, resulting in internal circuitry damage, especially with laptop screens. Typically, these issues require expertise to resolve. However, for very old computer monitors, it might be better to replace them with new ones.
3. Dead pixels on the screen
Dead pixels on the screen can be frustrating as they may occur not only on old monitors but even on new ones. Simply put, it's when one or more points on your screen fail to display color regardless of what's on the screen. The cause is the complete failure of pixels in the backlight panel to illuminate when current passes through. While there's no direct fix, you can check for dead pixels on your computer screen using diagnostic software and color display, refer to instructions on how to check computer screen for any dead pixels. A few dead pixels might not be a problem, but if there are too many, you should consider getting a new screen.
4. Cracks appearing on the screen
Cracks appearing on the screen have only one cause, user mishandling. Improper handling of laptops during transportation leads to impacts or lack of protective gear like shock-proof cases. Similarly, moving computer monitors to new locations and subjecting them to impacts can cause damage. Repairing damage caused by impacts to the screen usually entails replacement, the only viable solution for addressing this common LCD screen issue.
5. Screen emitting noise
When your screen emits noise upon startup, it's likely due to moisture in the power socket from prolonged periods of non-use or exposure to excessively humid environments. While not a major issue, it's important not to overlook it and address it promptly to avoid endangering users. Bring it to professional repair technicians for timely resolution.
6. Incorrect screen resolution error
For novice computer users, this is a common error on LCD screens, caused by inadvertently setting an incorrect screen resolution, not matching the supported resolution of the monitor. To address this issue, Mytour has articles and guides on how to resolve it. Specifically, you should refer to the screen resolution change guide, where you'll learn how to change and identify the most crisp and stable resolution for your screen.
7. Screen automatically turning off
When the screen automatically turns off without a specific time, there are several reasons leading to it, with the main one being a screen issue, possibly due to prolonged usage, causing some internal components to become unstable and potentially faulty.
Another cause could be issues with the monitor cable, which may be loose or poorly connected.
If it's the cable, the repair process is simple, but if it's the monitor itself, you'll need to take it out for a more specific diagnosis and repair.
With these 7 common screen issues, you can identify the problem with your computer monitor and learn how to fix it. Horizontal or vertical lines on a laptop screen can be very annoying. You should address these issues early to avoid disrupting your work. Moreover, consider purchasing protective accessories like shock-proof cases and a separate laptop compartment in your backpack to prevent horizontal lines, blurring, or cracks caused by external forces.
