Solving Common LG TV White Spots: Tips and Solutions
LG TVs often come with an array of features, but like any electronic device, they can encounter issues such as unwanted white spots or dots. These can be frustrating and may affect the overall picture quality. In this article, we will explore various types of white spots found on LG TVs and provide practical solutions to address these issues.
Causes and Common Solutions for White Spots on LG TVs
1. Caused by Calcium Buildup
If the white spots are due to calcium buildup, a simple solution is to use a mixture of water and dish soap. Gently wipe the affected area with a cloth dipped in the solution to clean the spots.
However, if the white spots are stains, they can be more persistent. These stains might be etched into the plastic screen and require a specialized cleaner. Visit your local electronics store and look for TV screen cleaners, often available in wipe form, which are safe to use on the screen.

2. Backlight LED Diagnosis
For LG TVs, white spots can also be caused by the backlight LEDs shining through the screen. This is a common issue, especially in older models, and is often due to a lens falling off the LEDs over time. This lens blocks the LED light, but when it falls off, the light shines through, creating white spots.
Typically, this issue occurs when the TV is disturbed, such as being picked up and placed roughly. The plastic lens becomes brittle over time due to exposure to UV light from the backlight LEDs. To address this, the screen must be carefully disassembled, and the lens must be reattached with a flexible adhesive like RTV.
Other Common Causes of White Spots
3. SMC Chips Contamination
White spots can also be the result of contaminants, such as soda or beer, spilling onto the SMC (Surface Mount Chip) chips mounted on the flex cables at the edge of the display. In such cases, the white spots might be due to corrosion of these chips. Cleaning the affected area with isopropyl alcohol (not the cheap stuff from pharmacies) might help, but it's not guaranteed to solve the issue.
4. Dead Pixels
In some cases, the white spots could be dead pixels. Unfortunately, dead pixels are not repairable, and the only solution is to replace the TV. If dead pixels are the cause, you may want to consider a new replacement TV.
Additional Tips and Recommendations
When dealing with white spots on your LG TV, it's important to first identify the cause. This can help you choose the right solution. For calcium buildup, a simple cleaning method might suffice, but for more persistent stains or engineering issues, you may need specialized cleaners or even a professional repair service.
In some cases, the issue might be more severe, especially if it is related to LEDs or pixels. Carefully checking the type of white spots can guide you to the appropriate action. However, if you're unsure, consulting an expert is often the best course of action.
If you're still struggling with white spots on your LG TV, consider reaching out to LG support or a certified technician. They can help diagnose the issue and recommend the best course of action.
