The colorless laptop screen error is quite common, causing the display image to no longer be sharp, only showing single colors such as red, blue, yellow or moving to black and white. This not only causes discomfort when used but also greatly affects the work.
Screen cable (signing cable) error
Screen cables (LVDS or eDP) are responsible for transmitting image signals from the mainboard to the screen. When the cable is loose, broken, broken or has poor contact, the transmission signal is unstable, which can cause the screen to lose color or lose some color strips completely.
Graphics card error (GPU)
Graphics card is an image signal processing unit. If the GPU is faulty or the VGA chip overheats, the output image may be colorless, distorted or not display accurately.
LCD screen broken
LCD can be faulty due to impact, mold, or degraded components after a long time of use. This causes the display screen to display the wrong color or completely lose the ability to display colors.
Screen driver card error
Driver is software that helps the operating system communicate with the hardware. When the driver is faulty, compatible, or not updated, the laptop may display the wrong color or completely lose color.
Incorrect display settings in the operating system
Sometimes due to incorrect color adjustments or enabling High Contrast mode in Windows, the laptop may display discolored or only display certain colors.
errors from the operating system or third-party software
Some color-adjusting and image effects software can interfere deeply with the system and cause display color errors. In addition, operating system errors can also cause the screen to lose color.
Mainboard error
Some errors in the image signal processing area on the mainboard can also cause the color signal transmitted to the screen to be distorted.
Note
A loss of color in the laptop screen can be caused by both hardware and software. Determining the correct cause will help you save costs and time for repair. If you do not have technical experience, you should bring the device to a reputable center for professional inspection and repair.
