Скачать или смотреть Fix Bright Spots on LG LED Television (LCD TV with LED Backlighting)

LG LCD TV screens may develop 1 or more bright spots after a few years. This will appear as white circles and be most noticeable when viewing brighter scenes. The white spots are caused by clear plastic circular lenses inside the screen coming loose. I believe these lenses are used to distribute the light evenly across the screen and they come loose because the quality of glue used to hold them in place is not very good.

If you have a bit of technical skill, a screwdriver set and good quality glue you can fix this problem yourself. It's a fairly time consuming process as there are many screws and several layers that need removing to get to the lenses.

Here's how you fix the white spot problem. Make sure you switch the power off and unplug all cables before you do anything else. Attempt it at your own risk and don't be sad if your TV doesn't work afterwards. Good luck!

Update: Thanks for all of the comments and subscriptions. Here is some additional information based on feedback in the comments:

1. When you disassemble your TV, make sure you are careful and note how components are ordered. There are several sheets (mostly white) before you get to the lenses/reflectors. These sheets need to go back in the correct order so try not to separate them. You may like to photograph each stage as you go so you can refer to the photos when it's time to reassemble.

2. The most common questions in the comments are about glue. I used Tarzan's Grip but others have had success with different glues. As long as they are strong glues that dry clear you shouldn't have a problem. Here are other glue suggestions - Clear Gorilla glue, Super glue, Krazy glue, E6000, T6000, B7000.

3. It was commented that you can use clear adhesive tape instead of glue to hold the lenses in place. Just make sure it is strong tape that will stay clear over time. Crystal Clear Gorilla tape was recommended and I'm sure there are similar strong tapes if you do your research.

4. Some people mention keeping the components clean. I did not need to clean mine but you could use a soft cloth to remove dust from the screen and sheets if required. There was also mention of using screen cleaner on the screen.
