Redness around the edges of a TV screen usually refers to an abnormality in the display of the screen, where some of them appear red or other colors of halos, spots, or coloring around the edges. This can happen for several different reasons, including, but not limited to, problems with the screen itself, faulty backlighting systems, or problems with the source and connection. Here are some possible causes and suggestions to resolve them:
The screen is broken: Physical damage or defects inside the LCD screen may cause display abnormalities such as redness around the edges. In this case, the screen may need to be replaced.
Pressure injury: If the TV screen is subjected to uneven pressure, it may produce color deviations in some areas. Check that there are no oppressive objects around the TV or that the TV is installed correctly.
LED backlight issues: For LCD TVs with LED backlight, uneven aging or damage to the backlight system can also cause redness on the edges of the screen or specific areas.
Backlight settings: Excessively high backlight settings can sometimes cause the screen to display unexpectedly. Try adjusting the backlight settings to see if that alleviates the issue.
Signal quality: Poor quality of the source or damage to the cable can also cause display problems. Try changing the source or check that the HDMI** cable is well connected.
Color settings: Abnormal color settings or image modes may cause the screen to display color deviations. Check your TV's color balance settings.
Reset your TV settings: First try restoring your TV to factory settings to see if the problem is resolved.
Check for updates: Make sure your TV's firmware software is up to date.
Professional examinationIf the problem persists, it is recommended to contact a repair professional or service center for an inspection, especially if a hardware problem is suspected.
Before determining that the issue is an issue with the screen itself, we recommend that you troubleshoot and try the above suggestions step-by-step. Screen problems often require professionals to diagnose and deal with, and disassembling the TV to repair the screen by yourself is a higher risk, which may lead to more serious damage or affect the warranty.
