Samsung TV WHITE SPOTS - DIY Backlight Repair of Fallen Lenses
Vložit
- čas přidán 10. 09. 2024
- Does your TV screen display bright white halo spots? This problem may be due to failed glue on the backlight lens bulbs, sometimes called reflector or diffuser lens bulbs (there may be other troubleshoot solutions to your problem). If you carefully tilt your TV from side to side and hear parts sliding around inside, this could be the fallen lenses. The weakened glue can result from long term usage under high heat and or humidity.
CAUTION: I AM NOT A PROFESSIONAL but this video is a complete walk-through on how I disassembled, re-glued the fallen lenses, and reassembled a "Samsung Series 6 (6300-6350) LED 65 inch television." Only attempt this DIY repair if you are willing to sacrifice losing your TV; meaning, you're willing to buy a new one if this approach doesn't work and or you destroy your TV in the process. Other than re-gluing the fallen lenses, there's a more advanced option of fixing the problem if you know your TV model details by replacing the entire backlight strips. You can try ordering backlight replacement strips from various electronic stores, shopjimmy.com, Amazon.com, Alibaba.com, or tvpartstoday.com. I AM NOT ASSOCIATED with any of these businesses but I too was looking for alternative solutions. I hope my video provides you some insight on how to possibly solve your problem, good luck.

Hello Joe, I really like your video because everything is done with great care showing each step in a clear and interesting way. I repaired my Samsung 75 inches which had 2 white dots. Once disassembled, I checked all the LED lenses and found 2 that had fallen off plus 19 others that could be removed just by brushing them with my finger. So I glued these 21 lenses back together with B-7000 glue. Then after 36 hours I checked and all the lenses had been glued. Then after reassembling the TV without breaking anything, I turned on the TV and I noticed that the 2 white dots from before the repair were no longer there, but that I had 2 new white dots and in addition that I had lots of slightly confused white spots everywhere. I displayed on my screen an all-white image (JPG) with a USB key, and it was with the all-white screen that I was able to realize that these slightly confused white spots were located precisely everywhere where I had made the 21 repairs. For this I compared with another image taken during the repair which shows the position of the lenses at the time of the repair.
Here is my question: Do you think I miscentered the lenses or the glue overflowed onto the LED or all of these at the same time? Or maybe it was the green adhesive tapes I used to hold the lenses in place while drying that caused a deposit on the white plastic around the LEDs? I have to say that trying to properly position these lenses by sticking them on the LED without putting glue on them is really not easy because they do not have a locking system to show where they should be positioned... I would have liked to send you my 2 images that show the dots and white spots and my 21 repaired lenses, but I do not know if it is possible and if so I do not know how to do it... Thank you if you can give me your opinion on all this...
Here are my thoughts: #1. If the lens itself is cracked or burnt, light won't diffuse properly... If the tape left any adhesive residue on the reflector sheet, light may bounce off of it oddly... if the glue spilled over onto the reflector sheet, when dry it hardens and or crystallizes, that too may deflect light oddly... if the lens bulb is off center, light doesn't diffuse properly... if glue covered the LED, that's a problem... if glue got on the bulb lens rather than just the peg ends, light may bounce off of it oddly... not sure if the glue you used was a problem... considering you had that many, there may be indications that other systems are beginning to fail as well (I've heard of pixel failure which doesn't display light and color correctly) and yes, I too wasn't fond of the lens design mechanism either. There was too much leeway for misalignment. #2. the cheapest approach to solving the problem is to re-glue the fallen lenses BUT even that has inherent risk because how many of us have had practice taking apart TV's, right? #3. The low cost DIY approach would be to replace the "entire bulb strips" after you've ordered the new sets. After you found that many (21) loose bulbs, the probability of getting them all on correctly was doubtful for ALL of the reasons you listed being suspicious AND there's obviously a looming problem anyway with the failing glue on the remaining lenses. I had a reference in my description to a business that sells replacement strips. This too though has risks because you still need to take apart and reassemble the TV correctly without breaking anything else in the process. #4. You take it to a professional repair shop and have them do it. (Which they will do exactly what #3 is, in addition to running other troubleshooting diagnostics but at least their work is guaranteed); however, nowadays, the labor, parts and repair cost MAY BE close the cost of a new TV anyway. Which leads us to #5. people chuck it and buy a new TV! #6. When I made this video, I had no idea this many people were experiencing the same problem. SAMSUNG or any other brand should take note of this common problem and correct it or is it just a matter of systems and parts eventual breakdown? The consumer wants quality and durability. #7. I agree with the lenses being difficult to properly center. Although I had 3 lens pegs to fit into 3 peg holes, there was no locking or snapping into place mechanism or solid fit when I put them back into place. Basically, a judgement call and keeping your fingers crossed. As I mentioned at the end of my video, if I were to do it all over again, I would go the extra steps and buy the replacement bulb strips. YOU may still want to consider that as an option and replace the entire backlight strips but then again, if you've had your TV for some time, other systems might be starting to fail. You certainly know how to take the TV apart now. The extra steps I only referenced in my video, (other videos may show it all), where you release the locking mechanism, remove the last white reflector sheet and gain access to the bulb strips. They can all be removed somehow and then replaced. #8. You certainly sound like you did your diligence, sorry to hear of your results. Thank you for reaching out and being very cordial in commenting.
Your video bring me back at youtube in 2010,
I like it because is from a man who documentary his diy job to show us how to fix problem like that.
Thx man, its really helping me 👍🏻
I wish you success on your own DIY project.
This is such a great video and helped me fix my TV thanks so much! I learnt a lot about your approach to jobs like this too, keeping notes, labelling pots with screws etc! Keep up the great work, cheers!
Great execution on your part Steve, glad it all worked out and I could be your guide.
Thanks, i'll try and repair my parents samsung with your video.
I wish you well on your project.
@@notyouraveragejoe855 Thank you, i tried it yesterday. All went well just up until the reassembly of the bezel. Apparently the screen was too close or too tight in a corner that when i clicked on the bezel, the screen broke in that corner. But, i think that the "suns" have burned into the screen because some of them were still visible afterwards. It was my parents TV and they've already bought a new one. They 've been watching for years on that TV and didn't see those 10 "suns" anymore. But, my pain was real, it was just a last try to fix the TV and my daughter hoped i could salvage the TV for her. But, thanks again! without the crack it would have been a succesfull fix. Is it possible the "suns" burned the screen?
Sorry to hear of that result. I even mentioned that particular concern at 15:21 when trying to replace the frame bezel over the screen... but, things happen right? It's not like any of us are TV repair professionals with years of experience. Another possibility is that if you don't properly center the re-glued bulb lens or you get glue on the center diode, it may not diffuse light correctly and thus, you still have a sun halo effect. The fact that you had 10 to get right is quite a chore over just 1 or 2. In regards to "burn in, screen burn, image burn," or as you called it "suns" being burned into the screen, (I'm no professional but) yes, I do believe there can be an appearance of that but it may not technically be that. It may be due to certain parts wearing out or no longer functioning properly and thus, gives off the appearance of a "burned" image. If that's the case, I don't think you can do anything about it. This topic is beyond my knowledge but I think it deals with degeneration of the pixels, the types of bulbs used or LED's, the LCD screen, and how light is generated and for how long. 1) If the bulbs had fallen off and your parents continued to watch the TV, the concentrated light source is no longer being diffused properly and could result in the "burn" image. 2) Although I've read that LED (light emitting diodes) apparently use less power and produce less heat than earlier model TV's, screens and bulb-light types, I've seen backlighting TV videos on CZcams that have caught on fire. Is it due to excessive heat or an electrical issue or other? If it's not heat, then WHY are so many people experiencing fallen lenses from failed glue? Is it the type of bright light that wears down the glue, like sunlight destroys plastics? 3) Having a still screen or logo image on for hours (pausing a video game or screen saver for example) may lead to pixel degradation and thus, the "burn" image. And finally, to my limited knowledge... 4) Because these new TV's produce such amazing colors and bright lights, you probably want to adjust the brightness level way down. Having a bright TV on all day, day after day, let alone if it's in a warm/humid environment, seems to not only degrade the glue faster but also possibly fries the pixels and produces that burned looking image. Thank you for being cordial with your update, too bad it didn't work out and congratulations to Belgium for winning 10 medals (cycling, athletics, and fighting) during the 2024 Olympics.
Omg this is exactly what my 14 month old Samsung TV is doing... I just bought a new one last month that I haven't opened yet but this is good news. I hope this fixes my TV. Thank you for posting this video!!
My TV with the issue is model tu-8000 crystal HD led TV. It's 75". Posting this in case anyone has same issues. I will be taking mine apart this week and I'll post back with my results
I wish you well on your project.
good job and well done on the info. just found one in the alley and after plugging it in, noticed the same problem, also heard something rolling around inside, otherwise works fine. looks like a future project for me. 👍
That does "sound" familiar, good luck on the alley find project.
THANKS!
You're a mad man, good job.
Hmm... perhaps more so before and happier after :)
Thanks! This tutorial guided me through every step on a 75" Samsung. Some issues with getting the thin bezels to fit tightly together but the white spots are gone!
Great job! I'm glad I could help someone else out.
Thank you 🙏🏾
I hope the video helps you out, good luck.
@@notyouraveragejoe855 I truly appreciate this video. This will be a great project for me to get started on. Thank you once again 🙏🏾
Thank you...a well done video. I feel confident it getting this done.
I wish you success on your endeavor.
thx for your step by step help, I fixed my TV, good video
Fantastic and great execution on your part.
you kind sir gave me the courage to open mine up...unfortunately for me all bulbs were in place (bought the tv second hand,i'm suspecting they changed the leds,so what else could be causing the white spots?maybe they forgot to add 1 deflector?)
Before you opened up your TV, you could have tilted it side to side / back n forth to hear and listen for the fallen lenses sliding around inside. If you didn't hear anything, that could have been an early indicator that perhaps your specific white light spotted halo problem may be due to something else; unfortunately, I'm not knowledgeable enough to help you... BUT, I have seen other troubleshooting videos on YTube that point out other options to try to fix the white light problem. You'll have to do your own research and see if any of those options solve the problem. Another thought to consider though is that even if the bulbs are re-glued on, if they're not perfectly centered, they may not reflect the light properly and thus, you still get the halo effect. This is one reason why I also mentioned in the video, you can take it one step further and buy replacement "bulb strips" that come already assembled. Otherwise, you may want to contact the second hand store and talk to them. Sorry I could not be of more help, good luck and thanks for stopping by.
Great how to do. Thanx
Hope that helps you out in some way.
Excellent step by step instructions for this job. Obviously, the factory did not use the best glue for these to say on to withstand the years of heat generated by the use of the TV. This video uses "loctite super glue" but a disclaimer to not be sure if this glue is the best to use. Other videos use other glues. Anyone know the best glue for these to permanently stay on? I only want to do this job once.
I hear you on only doing it once; hopefully, a professional TV repair specialist can reply. Ethyl 2-cyanoacrylate (ECA) is the primary active ingredient in most superglues but you do want to look for an adhesive that can bond plastic to metal and withstand heat. The lens is hard plastic and the 3 plastic prongs are glued to some sort of metal but it's not a snap in fit. You also have to center the lens and make sure no glue covers the center light diode; otherwise, the repair may not work. You can bypass all of the glue concerns by taking the extra removal steps (only mentioned in the video) and buying / replacing the entire bulb strips that come preglued. I referenced a contact in my description. Sadly, I was amazed at how often this problem of fallen lenses is occurring on TV's. I wish you well on your project, thanks for stopping by.
Thanks, you gave me the confidence that I needed!
Hi David, I wish you success on your repair (you're a man who works with his hands, tools, machines and wood - respect to you for that) but remember, there's risk with the attempt. If you don't get the bulbs on just right, (let alone don't break anything else in the process) it may not solve the problem but you can always go the extra step and purchase and replace the bulb strips. You certainly will learn how to take apart the TV to get to that decision in the process, good luck.
Done! Working fine! Opened and glued and back together!
Well done sir.
Thanks
I hope you found something useful from watching.
I cracked the front panel when trying to unstick the tape at the bottom, as my dog started barking and made me jump 🤦
Oh no, so much for man's best friend! Yeah, some of the parts I came across are quite fragile.
Thanks so much for this detailed video. I bought a second hand tv that has this problem. It’s great to know it can be fixed. Just a question is it not good to use the screw machine later on because I saw you used it at the beginning but not later on?
The drill machine will only work on the shallow screws unless you have an extended length bit. The other screws are deeply recessed within narrow channels but I soon realized, I wanted a better "contact feeling" with what I was working on so that I didn't strip the screw head or the internal housing the screws fit inside. That would create another problem! The extended length hand held screwdriver was the right tool for me. Keep in mind that you can also replace the entire "strip of bulbs" rather than gluing them back on individually, (I referred to this issue in the video. It takes a couple extra steps to do near the end, unlocking the reflector sheet and removing it, then removing the old strip of bulbs but at least you don't have to worry about if you glued them back on correctly.) I wish you well on your project.
did you determine in the end that the super glue was the right brand? what are the required attributes of I can’t find this exact brand?
There are other options but Ethyl 2-cyanoacrylate (ECA) is the primary active ingredient in most superglues. Loctite also makes extreme epoxy for bonding plastic (the deflector lens with 3 prongs is hard plastic) to metal (the 3 prongs go over some sort of metal but it's not like they snap in or click in, poor design?). Thus, they are glued on but you also must get the lens centered just right without getting any glue on the center light diode; otherwise, the repair may not work. I chose the Loctite super glue gel because of the easy squeeze applicator for precise control. Whatever brand you have available to you, be sure to check if it bonds most plastics to metal and that it can withstand heat. If that's too concerning or complicated, you can tale the extra steps (that I only referenced in the video) and order / replace the entire bulb strips. I put a link in my description that I found as a contact source for such parts.
Hi great video pal. When you fitted your first bezel is that just for the white screens and when putting on the top bezel what happens with them flappy bits at the side do they just tuck in.
After I replaced the two white sheets (thick heavy and thin fitment), the 4 flimsy thin black bezels will clip in holding the two white sheets in place (refer to video time of 11:50-14:00). The LED/LCD TV screen will follow and rest on top of and be centered over the bezeled white sheets. In regards to your mention of "top bezel and flappy bits at the side"... can you be more specific? Are you referring to the TV frame bezel and circuit boards? After the TV screen is centered, you will attach, (14:45 gently clip in and then screw in 5 screws) the black outer one piece Frame Bezel. The circuit boards still hang out of the way. At 15:32, is when I prepared to flip the TV over (yes, I placed the circuit boards up under the sheath strips to protect them when flipping the TV over but I didn't fully clip them in yet. If you can secure them before flipping the TV over, that's your option). I chose to secure them in after flipping the TV over. The main issue here is that you don't want to damage the circuit boards during the flip over. I hope that helps.
Great video thanks .. I will try ... I have a Samsung 75 6300 series
If you don't want to risk getting the re-glued bulbs on just right (which is free to attempt), then take the extra steps (undo the locking mechanism and remove the last reflector sheet, not shown but mentioned at 10:20 in my video) and buy "$" the replacement bulb strips that already come with glued on bulbs. You just remove and replace the entire strip of bulbs. I wish you well on your project, take notes, and be patient in the process but also, be willing to buy a new TV if it doesn't work out... Good Luck.
I followed your steps and my tv is extremely dark now. There is still a picture, however it seems like the brightness is at minimum setting even though it is at max.
Hi Nicholas, sorry to hear that but don't give up hope just yet. Let's say no other problem existed and no damage was done during the repair and you carefully handled the circuit boards, fully inserted the ribbons and properly reconnected "everything" back together. There's still a host of potential other issues that it could be. Since I am not a professional, I will refer you to this link: ( www.tcl.com/global/en/blog/solutions-for-tv-screen-that-looks-darker-than-usual ). It's just one link of many that you'll need to do some research on but perhaps all you need to do is troubleshoot your settings/modes and adjust them accordingly, (other than brightness because that would have been too easy, right?). Since the TV was unplugged and taken apart, altered settings/modes may have occurred. I wish I could help you more but I did say in the beginning, you must be willing to sacrifice your TV. If anyone else is reading this comment and knows the answer, please reply. Give me an update Nicholas, if you find the remedy and good luck.
@notyouraveragejoe855 I had just forgot to plug one of the boards in. It was tucked under it but not actually connected. It's up and running great now!
Fantastic, glad it worked out and good job on double checking your work and finding the missed connection.
Great video, but man is this going to be tedious to fix my stupid TV
I hear ya and pack a lot of patience because you don't want to break anything else in the process and then cross your fingers when you put it all back together and turn it on... good luck Eric.
My luck I'd go through all this trouble, glue all the fallen/loose bulbs, get it all back together and two weeks later another bulb would fall off.
Yes, there is that risk, lol, among others including did you put the TV back together properly without breaking anything else in the process? Although no guarantee, you can work around the glue issue by taking the extra removal steps and purchasing the entire line of replacement "bulb strip" sets, but as you alluded to earlier, know thy own luck and limitations. Take care and thanks for stopping by.
