Thank you so much for this video. I just fixed my LG 55 TV. I was puzzled when removing the screen (minute 2:10) because you did not explain what you did to disconnect it. I figured it out. My TV is working great. Thank you again.
What was the fix when you turned ir on for the first time and there was only some light but not the picture? It happened to me exactly? Did you forget to connect something or what was the solution? Thanks!
I sent my TV (LG 42LB65) to be fixed by an LG-certified repair center here in Egypt. The backlight strips were replaced, but instead of bright white spots, there are slightly dark spots, which can be noticed in video games with large bright uniform scenes. In other words, my problem was mitigated, not completely resolved. When I called the maintenance shop, they told me this is due to the fact that the components of my TV (especially the power supply) are old. I bought the TV, as far as I remember, on 2/2/2015, making the TV over 8 years old at the time of repairing (late May 2023). The weird thing is that the sightly dark spots are there despite the backlight being very very bright. Moreover, on some contents colors seem to be "washed out"; too much pale color on the screen, especially RU-vid videos. Several technicians I know tell me different things, but most notably that it might be an issue with the quality of the LED backlight strips. The strips I installed are not a genuine kit produced by LG, but a Chinese one. The repair shop told me that the genuine backlight kits are far more expensive and are not available; all those who claim to sell genuine Korean LED backlight strips are lying. I need help, can this issue be 100% resolved? Can this issue persist due to the TV being old? I want to fix the issue 100% and have my TV like new again. Do you think someone here is lying to me?
You should replace the LED strips instead of gluing on the old lenses. Gorilla glue and other super glues will dissolve the phosphor coating on the LED, turning them from white to blue. Clear silicon will change how the lens diffuses light and you'll end up with bright spots. Once you've gotten to this point, you might as well just pay $50 for a new set of strips!
Two suggestions: 1. Based on other videos, it's important to check all the diffusors. Since you have already had so many fall off, it's likely others are loose as well. Maybe you did this, but you did not show it or talk about it. 2. Rather than try to use the glue bottle itself to apply the glue, squeeze out a couple of drops onto some plastic scrap, and then use a toothpick to transfer a tiny drop to each spot on the diffuser mounting surface. Much easier to control, much less chance of squeezing out too much and smearing glue somewhere you don't want it. I can't help but comment on how half-assed this diffusor mount setup is. Glue? Really? Far better would be a simply plastic snap assembly, with plastic or flexible metal fingers molded into the LED strip fitting into depressions molded in the sides of the diffusors.
@@King-Sherry That's the best English I have. I'm just saying that the diffusors could be designed to be a snap fit into the LED strips, rather than relying on glue. I'm guessing glue is used to keep the cost down, at the expense of long term reliability. There are enough YT vids on this kind of repair to make it obvious this is not an uncommon issue for LED TVs.
@John H How can I find a snap fit strip, if I do it won't be from the original manufacturer so whats the point. Or do LED lights not matter when it comes to originality. Plus can you send me a youtube video please because all i'm finding is glue videos. The design of these strips is deliberately poor because these sack sucking companies know nobody is going to change a good TV for atleast 10 years. I hope they burn in hell
@@King-Sherry I'm no expert, but so far as I know there are no LED TVs that do not use glue to hold the diffusors, so there are not going to be any YT vids for that. My point, that you seem to agree with, is that not many manufacturers worry about long-term durability of their products anymore. And not many consumers are savvy enough to pay a little more for it, either.
@@bogotabro experience. Plastics can be as different as glues themselves so it's not one size fits all. The right glue for the type of plastic and environmental condition is critical.
