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 !! 👍🏼🙏
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
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!!
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
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
I broke so many tabs while attempting to fix it. Well, i got it done. Lol. It works. I just got a question, i think mone has still some burnt panel or panels. Do you think the diffuser may just have some soot and could be cleaned off with soapy water?
@@juanes9569 not uncommon further to be some kind of ash residue from a burned out LED. If it's on the diffuser you can use a scraper of some sort to usually take it off.
Hi, quick question. Same TV, but 82 inch version. My backlight is definitely out, but, so is the picture. I get sounds when it powers on, when the LCD connection to the far left is disconnected. When it is connected, the TV just resets in a power cycle. Would you say that the LCD panel is bad?
Yeah that's a com failure between the panel and the main board. I would try replacing your power supply and your main board first. Because if it's a panel then you're pretty much SOL unfortunately.
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.
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.
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.
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.
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?
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.
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?
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?
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.
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.
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 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.
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
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
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.
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?
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?
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.
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.
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 😅
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 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.
@@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.
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!
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 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.
@@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.
@@天-f8x how bad is a broken? Sometimes on those you can just line them up next to each other and they'll butt together. Usually more than well enough that everything will go back together. Unfortunately those inner pieces are not usually available outside the factory.
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.
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.
@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.
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
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.
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.
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 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.
