Had a crescent moon shaped bright spot for a couple years so I guess a lens was loose. Actually heard something fall down inside the tv and now it turned to a bright circle. Thanks for the explanation.
just before we started this repair, the TV started to go dark intermittently. We took tv apart to discover that the loosest lens has a burnt out LED circuit. I have seen another repair which tells you how to replace this strips.
Why don't they use stronger glue on the lens? Or better make them heat-resistant plexiglass with pop-in hooks on the feet to pop them into the circular hole on the plate around the LED. Done the lens stay in place forever.
I’m a 73-year-old single woman who doesn’t know a thing about how to fix TV problems. My LG 40-inch TV has 3 rows of fuzzy light spots that I see most clearly on a light, solid background during a color movie or program, but not so easily during a black and white program. I was hoping it would be an easy fix, but it looks complicated for someone like me. 🥺
It worked!!! Tank you very much. A suggestion I can do is to never lift and never touch the screen. Lift the TV leaving it on the table and then place the TV on the screen from above. This should minimize the risk. In my case the screen was malpositioned and ther was a little brighter corner, but I managed to push it in position from outside with a flat head screwdriver. Dangerous move, I know, but it was just less than a mm and it worked.
As you will see near the end of the video you remove the 'flexable dark' screen which is really a flexible PCB. On my 2014, yup 10 years old the screen was brittle and internally my screen broken into fragments when I gently removed it. Moral of story, a new 50 inch LG is $300ish, so you might just replace the TV. However, it's awesome to see how its made.
I tried this. there is so much on this that does not work. The dots are not the same for each place where the diffusers rest. Once the glue is on, it is extremely hard to get it in the right spot. The glue almost seems to melt the plastics... and does not hold as well as it should... Just decided to buy the led strips with the diffusers on them. I think the batch in the set was really bad. some diffusers seemed to have a few of the nubs gone. Almost all diffusers were off..
So..... Basically the white spots will stay.... Lol too much work to fix something that shouldn't occur. There be 500k views, means a lot of people have this issue with this brand. Lol
I'm having a hard time finding my issue. So I have a bright spot on my LG TV...but it's not like THIS pronounced. You can only really see it if there's almost a full white background. It's this one spot to right of the center of the TV, and it looks like it's whiter than the rest of the white, but it almost has a blue-ish hue to it. It's hard to search Google for because they keep bringing me to videos like this where it seems like a different issue entirely.
Ya beauty! Good video and that's mine all fixed. Had 12 spots and the rest ofnthe lenses just flaked off. As for breaking the screen, if you go easy you'll do it all right. My only scare was the final bit to expose the lenses, there's a few stealth clips that really hold their ground. Big thanks
Good question. Probably not if you can get a new TV that cheap. Might be good to give your old screen to someone else who can fix it or recycle it so it doesn't go into landfill though
@@westozexplorers1885 we have a good recycling program here, they do accept flat screens. I don't have this issue myself but I expect a shop would charge at least 200 dollars to do this job. I imagine there is a fairly high incidence of screens breaking during the repair.
Thanks for commenting. Sorry to hear that. I'm sure there are plenty of others who have had the same problem. Those sheets and other parts are quite fragile. There is no guarantee that this fix will work for everyone and parts will get broken. You'll notice I snapped one of the little plastic tabs around the 8 minute mark of the video so it is a delicate operation.
I have a Samsung TV. Are they made the same way? Thanks very much. I only have one, which is not terribly noticeable. Don't want to go thru all that for just one that only shows when screen is light. You don't see it when there's a dark scene.
Depending on the age of your Samsung they could be made with the same type of reflectors/lenses. If it's not annoying you then I wouldn't bother trying to fix it
@@westozexplorers1885 Thank you for reaching out. Yeah, it's about 8 years old but still has a good picture, plus I've been wanting to replace the WiFi adapter. But no, it's not a terrible appearance where it fell out. But thought if it was apart for something else, maybe give it a look. Thanks again, take care.
A point that might save someone from killing their TV. if you're wearing ANY synthetic fibre clothing at all, natural body movement can generate surprising voltage figures in static charges. If so, delicate electronics can be snuffed right out if your static charge discharges via the TV circuitry. Tiny chips especially can be very, very voltage-sensitive. To get around this possibility you can do one - or more! of three things. 1. wear thin plastic gloves. or pull plastic bags over your hands, secure them on your forearms with maybe tape or rubber bands. 2. connect yourself to a known earth point like maybe your central heating radiator. 3. wear only cotton fibre clothing. That doesn't generate static. (That's what I'd do myself) It would be a real shame if after doing this job so carefully you then find your tv won't start, or loses tune or some such electronic problem because you weren't aware of the above?
Thanks for your advice. Static damaging computer components, TVs and other electrical equipment was something discussed regularly in the past. After building and servicing hundreds of computers for over 20 years, I've never seen components damaged by static in the real world though.
I won't show this to my wife. I've got a few white dots recently and used it as a valid excuse to get a new TV. But now thanks to you my old LG 60" has a chance for a new life. Somewhere in the patio :D
I personally used Gorilla glue but there are plenty of other suggestions in my video description and in the comments. I used a wooden skewer to apply the glue to the 3 little feet on each lens/reflector.
Thanks for the video! My son and I just did the repair on his 42LF5600. It has 32 lenses, and EVERY SINGLE ONE had fallen off. We did the repair using clear gorilla clue. It is much much better! We still have one somewhat bright spot, and another slightly dim spot. Reading the many comments below, it's possible that we didn't align two of the lenses perfectly, or perhaps used a little bit too much glue on those. But this is so much better than the 4 by 8 grid of bright spots that we had at the start.
Thanks for the comment and good job putting all the lenses back on. I don't know if anyone has had a perfect result, I know I didn't, but my TV screen still looks pretty good years later.
Thankyou so much! Just fixed my 55inch LG tv which I gifted to my mum (she helped!). Really appreciate you taking the time to make the video, what a legend!
Hi Animesh. Sorry for the late reply. It's possible but I couldn't say for sure. If you look up your model, there might be someone else who has a repair video
Hi there! This issue seems to be so common now based on the amount of videos and comments from users with the same issue from many different manufacturers. My question, is there a different type of screen/display that does not use these types of stuck on diffusers/lens? So I can keep in mind when making any future television purchases.
Thanks for your comment. I actually don't keep up too much with TV technology but looks like the technology has changed a bit since I fixed my old LG. Seems to be plenty of OLED and QLED TVs being sold now.
Back 8 months later to say this was a great guide I was able to do it 8 months later without needing to watch this again. I suggest for anyone doing this to get a magnet bucket that way you can group the screws so they don’t roll around and get lost. It was a life savor when putting stuff together. BE EXTREMELY GENTLE WITH THE INSIDE PARTS.
Thanks for commenting and great advice about the magnet bucket. Yes, always be gentle when working when working with appliances like this, with all the fragile parts that can break easily
Incredibly useful video, was able to fix my TV even thou I initially thought I would need to get a new one. Thank you very much for the video guide on this issue.
I went from a perfect 55 inch LG to next day 12 bright spots. I think my over powered 5.1 up stairs rattled out the lights on my LG downstairs. When I turned it on one day it had 9-15 bright spots. I followed this guide to a "T" and it was 300% accurate. There was 12 bulbs on the bottom of the TV. Thank you so much for this video. May change review tomorrow when I can't put it back together again. Lol Sept. 24/2022
