Spent 2 and a half hours and my TV is fixed, works like nothing ever happened.
Thank you man, brilliant job explaining everything!
Just fixed my TV, with the help of your video, and everything is working now. Thank you for the detailed explanation :)
Samsung contractor wanted $900 to fix my 65” LED UHD TV (less than two years old). I ordered some $30 eBay LEDs off eBay for my tv model and followed this guide (slightly different but I found my way) and now my TV is back alive!! Thanks
U order your replacement screen off of eBay for 30 bucks
Possible to share led strip product name you bought from eBay ?
Just gave me a glimmer of hope
900 Dollars Wtf???
Thank you so much. Fixed my 4 year old 75 inch Samsung TV using your video. Not only did I save myself a lot of money, one less TV in landfill.👌🏻
Thank you! Just fixed my Samsung QN75Q6DRAFXZA! About $50 and 4 hours of my time, but much cheaper than a new TV. Never did figure out how to get that IR sensor / power button off, but I was able to leave it attached to the frame
Great video! I managed to replace the backlight on my 65" Q60R following this guide. Thanks!!
IT IS NOT QLED BUT NORMAL LED TV CORNER??QLED HAVE SMALL REFLECTOR LEDS TUR ON OFF INDEPENDENTLY
Thanks a lot for you and all the other youtubers. I managed to watch these videos and fix my TV for just 1/10th of the repair cost.
I've always fixed my own stuff, from the car to the washer, computers, you name it.... But not trying to crack thr LCD was nerve racking but was able to fix my samsung TV. Definitely watch the video at least one time all the way to the end and then work along with the video. These videos give you the confidence to do stuff. Thanks man!!
Yep just completed this with my sons tv. Worked perfectly. Great tutorial. Thanks
Great Video! Fixed my Tv with this tutorial! Thank you🎉❤
Great job on the warning with the ribbon slip, alot if tutorials they fail to mention it my first I I did that damaged far left ribbon only left end about 2 inches black where ribbon ripped, ever since then I now avoid that mistake when fixing leds, and mention it in comments on several tutorials
My job is replacing one of these TVs soon, and they're letting me take it home. Thanks for this video, it'll be worth a shot to put in new LEDs. If it works, then I'll get a nice big TV for pretty cheap.
Thank you so much, this worked for my 75 inch QLED QN75Q6DRAF! I got the leds from eBay!
Eine sehr gute Erklärung ,sehr ausführlich leicht verständlich ,und man spart sich eine teure repartur im Fachhandel
Fantastic video. Thank you so much for sharing.
Wonderful video sir, Thanks.
Congratulations.
Great job, thanks for sharing.
I scored a 65 inch Samsung for free and replaced the leds for $51 not bad. Thank you for this video.
IT IS NOT QLED BUT NORMAL LED TV CORNER??QLED HAVE SMALL REFLECTOR LEDS TUR ON OFF INDEPENDENTLY
Great tutorial. My only gripe is I wish you had shown the Samsung power on self test at the start. Would have saved me pulling the screen apart. But you certainly helped me out. Cheers
Really good tutorial 👌. However I managed to Crack my screen trying to remove it without suction cups. Oh well. Chalk it up to a learning experience.
Thanks for the video!
Question: the unit I have got too hot along the bad leds and warped about a three inch section of the rigid diffuser and adhered the reflective layer to it in that spot. It was cooked to the point of crumbling/flaking from reflective layer. Upon reassembly, everything works but the warp causes a slight shadow in radians upwards. Is it possible to turn the diffuser/reflector bottom to the top of the set so it's not affecting immediately in front of led strip?
Yep. That happens. See my other Samsung TV video. Similar issue on an older TV.
I just changed both the led strips out, really easy. It worked great for 30 min and got the blackened area again. I suggest changing the power board at same time, no doubt that was the problem also.
Depends on if you had a catastrophic failure on one of the LEDs in the strip. If so, it can cause damage to the voltage regulator.
@@qcsbuilds5708
Orig the shadow was on right side , several leds burnt on both sides when pulling, with burn burn marks on bottom of back paper. After replacing both strips, shadow appeared on left side.
Thank you so much !! You just save me to pay $800 dollars to get fix it or buy new tv , mine was 2 years old 75” QELD !!! Paid $32 eBay for the backlights strips then installed and now works perfect !! Awesome tutorial video !! 👍🏼🙏
The very last white thin layer against the back was double sided taped to the back. It tore a quarter sized hole. What's this paper called? It can be rolled and shipped if I'm lucky. it's not stiff.
I just used a lego pry piece and was able to take the back off easily.
Great video. Very informative. I have a QN75Q70. Is it normal to have the entire, both strips, backlight fail at the same time? I can see the picture with a flashlight.
That set actually has four strips. More than likely you've either had a catastrophic failure on one of the LEDs or you've got a bad power supply... Or both.
Looks like a pretty solid tutorial; may have to do mine. My only comment would be to spend the $10 on some trim removal tools; you definitely scratched up that plastic casing using metal tools on it.
Idk how.. but I did it. Thanks!
I didn't have suction cups so I put double sided tape on my hands to lift the screen lol.
Damn this video had potential. Camera man needed
im trying to fix a samsumg q6 series 55'
It doesn't have a complete black part but is much darker than the rest of the screen, I assumed it was the back light, but I dont have to much idea how to dial with the screen inside and not break anything, hope you have a chance to make a video about it
the infrared sensor is messed as well
So you're going to need two people. That one I believe the screen is actually adhesively attached to the outer frame. So when that one you're going to have to remove the entire outer frame carefully to actually be able to access the back lights.
@@qcsbuilds5708how do I know which led I have to buy?
Hello, I have this exact TV with the same problem. Where would you recommend acquiring the led lights like you installed on that tv?
ShopJimmy.com or encompass parts
Thank you for this very informative video. I own the QB65R. Does it have the same LED light strip? Can you share the model od light strip i need to order? I am from the Philippines so it would be a bit difficult to source it out. Thank you so much! You earened a sub.
I would try shop Jimmy or encompass parts. But yes they're the same type of light strip.
I have the same tv. I have installed new LEDs and they work but it’s still slightly dark near the top, like a dark wavy like spots. Could it be the layers or the power supply itself?
Sounds like you're layers slid or shifted during assembly
Hello! great video and directions, Thanks!! my issue is yellowish half screen, do you think it is a misbehaving led?
it's a Q65 tv
I have this same issue of a yellowish right 1/3 of the screen. Interested to hear what people believe this to be
Thank you for the more in-depth video about this type of TV. Im waiting to hear back from Shopjimmy about the LED's for my TV.
I wanted that ask about the LED's, just a day before my LED strip went out I noticed that on the bottom left side you can just see the lights coming through the screen and out at the time I wasn't sure what that was also noticed that it was a little hot in that area and then the next day the lights went out on the left side I guess so now I have a dark screen on the left.
While I was checking the settings I noticed that the LEDs on the bottom right side started to Glow harder to where I could see the lights coming through the screen so I turn the TV off before they burnt out.
Do you know that with the LEDs getting really bright and warm before they went out does that mean my power supply was causing the LED problem or does that mean the lightstrips themselves caused issue? Thanks again for the video!
No it's not a power supply causing the failure. It's just the LED running at full brightness that slowly burns them out.
I need to order this pard but whare lol
@@thefakeduchtsman try shopjimmy.com
Looking online at replacement strips, they have ones with the same original square LEDs and some other have kind of a wider horizontal/rectangular LEDs. Does it matter?
There's going to be a version number on the back of your TV by the model number. Make sure that the LEDs that you're ordering are compatible with your version.
My television is model un65ru9000f but I cannot find replacement LED strips according to the model. I want to know if I can put the LED strips from another television model on it.
BN96-46032A that's the part number.

To anyone: My samsung qled 65" qn65q70aafxza had this issue initially (half screen is black). I was going to follow this video as it has the same issue, but know ALL of my screen is black with a little bit of flickering on the bottom part when turned on. Do guys think that it is still an LED back light issue? Or is it something else?
I have a Samsung UN75R07F100FXZA 75" 4K TV. Looked up the part number and ShopJimmy has 'em but, it's a set of 3 strips. Samsung has them in stock too but, they only provide one strip for this model so, do you happen to know how many led strips the tv requires? Don't need 3 strips if the tv only requires one strip. Thanks.
Usually back lights always come as a kit not in individual strips. So where Samsung is showing you just one it's probably a kit.
@@qcsbuilds5708interesting because, shopjimmy has a kit of 3 strips for $69 whereas, samsung has what it looks as one strip for $49 hence, if I end up needing 3, it'll be three times $49, instead of just $69 for all 3. Follow what i'm saying? I know going directly to samsung will generally be more expensive so, just wanting to make sure before I spend $49 for one strip, when in the end I need all 3.
Hi, is it not possible to check the QLED with a normal led checker?
Thank you very much. Worth watching video.
Yes. However sometimes it's just a little on the tricky side depending on if they're commonly grounded LEDs or if they're independently grounded.
I have a similar issue in my Samsung but instead a complete side is more a “stain”…I can see the image colors but is not so bright… it’s this also related to the backlight?
Sound like you have a back lit TV and not a edge lit, but yes totally sounds like bad back lights.
if the plasic difuser screen had led burt on bottom is it okay to flip it 180 so the burn marks are on top
No because if you notice the diffuser is etched like a piece of fiber optic. Best thing to do is clean and scratch off with a razor the burnt edge as clean as you can.
@@qcsbuilds5708what would happen if you did flip it would the picture be blury or not work i am wondering is that for all tvs or qled tvs.
Edge lit
I have a qn65q7daaf, I am getting no red light or back lights when I plug it in, I’ve replaced the power supply and the motherboard, and still the same outcome, I didn’t know if I needed new back lights for it to turn on. Thank you a appreciate any help
I have also tried the Samsung power on Self test and I’m getting no back light leds
@@b4s3b4ll08 then you need a power supply. Shopjimmy.com
@@qcsbuilds5708 I have replaced the power supply. That’s why I’m scratching my head haha
Got the power supply and motherboard from shop jimmy
Hello, could you let me know from where i could get the stripes for my Samsung GQ65Q80TGTXZG? Best regards J-P
Shopjimmy.com or encompass parts
Where is the best place to buy the LED from. I have checked Amazon, Ali Express and Ebay. they all have different price so was not sure how to chose the best LED for my TV?
I always get mine from shopJimmy.com
For anyone that tried this guide, how long did it take you to complete the repair?
How do u remove what called LBS cables? because I’m afraid I may break if I pull on it
I found on CZcams 👌🏼
The lvds cables are just a standard ribbon cable. If you look at the connector it should have a little black tab on it that lifts up that's lock. Then just gently slide the cable out usually there's a little blue pull tab.
I have an 85” Samsung and it has a similar issue but the left side is just dim not completely black. Like 30% as bright as the other side. Do you think it’s also the leds or something else? I just would hate to take it all apart if it’s the wrong issue. Already called their tech support and went through the troubleshooting stuff and they told me it’s $1,500 to repair. Have photos if needed
You could try a power supply it might be one of the regulators is bad. But I would say it's more likely that it's a backlight issue. A power supply is way easier to replace and test.

I have 65 inch samsung with dark shadow appearing on left side. Do all 65 inch tvs just have one strip at top and one at bottom? The shadow seems to be across all the left side but it seems strange that both led strips have failed at same time. Great video by the way
There's two strips, a right and a left on the bottom. More than likely you've got a burnout on your left strip that's causing that into the strip to go out.
I have the same tv, where can I buy the LED strips? Could you post a link?
Shopjimmy.com
Where did you obtain your LED back light strips?
Shopjimmy.com
Is a Samsung Frame TV, like my QN65LS03BAFXZA, similar to this? Also, where do you buy spare parts from?
Also, is the LED strip the issue for a vertical brown irregular 4" strip about a third of the way across the panel? I can still see the picture, it's just dimmer and brown.
Really don't want to take this apart to check the PN first and have it take up my entire dining room while waiting for parts and possibly get dirty or damaged. I found the part on another site, but not clear it's correct. Shopjimmy says this is the right part for QN65LS03BAFXZC and QN65LS03BAFXZX, but no LED strip listing for QN65LS03BAFXZA.
@@robmacphee4239 sounds like you've had an LED that catastrophically failed. If it's a neo-based panel then no it's directly backlit. But the strips are replaceable. ShopJimmy.com is a great resource
@@qcsbuilds5708 czcams.com/users/shortseQ-LOnHcKRs
Video sucks after uploading, but I think you can get the gist. Is this a panel replacement?
@@robmacphee4239 no just back lights
Hey very interesting video. I am not sure this is something I could attempt without breaking something, but it was very informative. I have a Samsung frame QN65LS03BAFXZA, and Samsung service was not helpful at all. 16 months after purchase and they are telling me I’m out of warranty and they have no local service so lots of luck, have a nice life. Before I try and find someone locally or do it myself, I was hoping you could help me figure out if it’s a panel or backlight issue. It’s a purple vertically oriented strip occupying 1/4 of the screen. I am assuming backlight but was hoping you could provide some input. Thanks.
Usually if you have any kind of color issue it's usually a panel aka LCD glass issue. And that's usually just replacing the TV altogether cuz it's almost as much to do that as it is to buy a panel and swap it. You had a dark spot then I would say it's backlight. But where it's a vertical bar basically I'm going to say it's very likely a panel.
Does this apply on Samsung qled QN65QN85AAFXZA?
That's a neo q LED. The panel tear down is about the same the back lights power ever are different. Backlight removal is going to be more like The TCL video where there will be strips.
Is this similar for the 75 inch qled?
More than likely depending on the model
I had the same issue with my 65 samsung I changed the led it works but after couple minutes it’s burned again, do you know what is bad the power supply or the main board?
The power supply is what actually controls the voltage to the back lights. So I would change that it keeps blowing LEDs
@@qcsbuilds5708 thank you Sir for the quick response, is there any way to diagnose the power supply? thank you
@@imadpola6782 no
Those edge clips can be snapped loose easier if you gently tap the clip areas with the side of a screwdriver handle while lifting. The action of tapping causes the snaps to loosen with less strain than lifting and jiggling. BTW, those "ribbon cables" are called "FPC" of flex-printed-circuits.

Is not possible to do it upside down? keeping the lcd and other layers together in the table and removing frame from back?
You can depending on the set. The difficult part is being able to lift the panel out of the screen and then getting it the all line back up when you put it back together.
@@qcsbuilds5708 Thanks, mine is a 75Q70R, I am worried about moving the lcd and layer around, but I understood, really seems trick to put everything togehter in the end.
@@andrekuros5148 The key is to just put everything on a clean service and take everything off one layer at a time or one set of layers at a time. That's why I will take the glass off and then stack the layers on top of the glass on a perfectly flat surface.
@@qcsbuilds5708 I have another question: this TV (75Q70R) has full array dimming. I checked the LED driver; there are four outputs to power the backlight, all with several outputs at 113 volts and others at 14 volts (I think it's for controlling the regions?). So, the power is going to the LEDs strips. But none light up. If there was a problem with a LED or a strip, would it make sense for all to be out? Being full array, shouldn't a failure only affect a local area?
@@andrekuros5148 on a Samsung you can do a power on self test. Disconnect your main board from the power supply and then just plug in the power to the power supply. The back lights should kick on. If they don't then either you've got bad back lights a bad power supply. If you disconnect the LEDs you can measure the power off the power supply with a meter.
17:07 - I'm pausing here and gonna come back when I'm more ready. Someone had one of these TVs by the road this afternoon and I brought it home to see what was wrong with it. Took me a few to find a compatible power cord. The backlight on the right side when you're looking at the screen is out (opposite yours), otherwise it's fine. Is there any difference between the the backlight parts? Or is it the same on both sides? I want to make sure I get the right part. Because, of course, FREE MONSTER TV! 🙀😹
EDIT: Nevermind... I shopped the part and they come as a pair. Continuing watching 😅
You want to change them as a pair. Otherwise you'll be doing it again within a year.
@@qcsbuilds5708 thank you. I was assuming as much when I saw the setup. I've done countless computer repairs and definitely learned THAT lesson 😅
Do the Samsungs always have the LEDs on the left go out? Lol
I'm hoping i can fix mine myself. Thank you for the informative video!
No it's 50/50 but if one goes out the whole strip dies.
Is it one or two strips? I got 2 with my order
Two right and left
Hi freind i have a vertical black line can you help me
That's likely a failed panel. Unfortunately you're a new tv.
@@qcsbuilds5708 Could there is not a problem connecting the cables?
@@kaledba usually not with a single black line
Are the buffer boards replaceable?
They're part of the panel. So yes but only if you order a whole new panel assembly.
Hi, I've had several LEDs blow on mine, they've burned holes in one of the thick white panels, could you help me with he info for the part numbers I need please. I would attach photos, but I cant.
Thanks.
So on those diffuser panels if it's not cracked sometimes you can clean it or you can take a razor blade and you can just kind of scratch off the burnt part of it. Otherwise I have seen them crack under the heat and unfortunately there's nothing you can do about that you'd have to buy a whole new panel. At that point you buying a new TV.
Thank you, regarding the blown LEDs, could you put a part number on here for those please, it's at the bottom of my screen where they have blown.
@@sixphredd Go to www.shopjimmy.com/
or
encompass.com/
to look them up. They'll likely be model and version specific.
Thank you very much
Is q led self lighting?
No only OLED or QD-OLED
I really wish manufacturers would stop using plastic clips. It is almost impossible to open a device without breaking at least a few of them.
It’s on purpose
Where I can get the back light
My model 8s qa65q60tak

Do really have remove the boards to replace LEDs???
No... But you do have to disconnect the cables from the main board to the panel.
Is it just me thats concerned that a tv not even 2 yrs old requires this type of repair? Or does it depend on usage hours and type of usage?
Exactly that. Depending on how many hours you have it on and depending on if you runit on vivid picture mode, or standard or movie mode, it makes a big difference in the longevity of the LEDs.
IT IS NOT QLED BUT NORMAL LED TV CORNER??QLED HAVE SMALL REFLECTOR LEDS TUR ON OFF INDEPENDENTLY/IF ONE LED BURN OTHERS LEDS WORK AND TV IS OK
If the diffuser glass is cracked, will it work properly?
Unfortunately no you're going to get glary reflection in your picture.
Where would you suggest getting a diffuser panel?
@@teresacarr7740 unfortunately you're not going to be able to find one. You're going to be a new TV.
At the end I'm like it's not fixed ..and was like oh wait that's just mine. Haha I have a thick black line just right of the center. 😑 it's a samsung un65nu6900.
So one of the panel ribbon cables became damaged while transferring the glass. Unfortunately it happens. But you're a new panel or a TV 😔
@qcsbuilds5708 I haven't done anything yet. Was just doing some research. But ya that sucks. It started as a faint flicker and just gradually got worst. Now it's just a tinted thick line.
@@coryo617 okay I misunderstood. That's a bad ic controller in the buffer. Unfortunately you are still either a new panel or a new Tv. Probably more than likely a new TV.
@@qcsbuilds5708 ya. That sucks. Not even 4 years old. Thx for the feedback
Samsung mavise marque toutes les tv samsung ils sont ce probleme
All LED backlit TVs will have this type of problem eventually.
1.5 years and my did the same thing. Will not buy a Samsung TV again
can't see it clearly.
