- In this video I will show you how to fix a Samsung smart Tv that keeps restarting model number (UN55KU6500F) this is a curved tv so you will need a pillow to help support the screen while taking off the back cover.
The issue was the PWM BLU pin was shorting so the mainboard keeps rebooting you can fix the tv by just disconnecting this one wire and the tv will start up fine.
If anyone knows what the PWM BLU pin is really doing or how to better fix this issue please comment below. ("Note I found that after doing this trick - go into settings and do a tv-reset fixes the issue. EG the PWM was too low so it made the tv restart, after the reset you can re-connect this pin and everything is fine. )
This video will hopefully save you from buying a new tv, please like and comment to help promote this easy fix.

Does anyone know the the PWM BLU pin does I think it dims the backlights but I am not sure why it power cycles the tv, my guess it's a mainboard issue or power supply not sure yet.
The reason may be in the LED, meaning that the LED feed is drawing less than usual, and the protection has been activated by the pressure sensor
@@molodmhamed4066 you mean current sensor
@@NewsonsElectronics When disconnecting the pmw, this sensor for LED errors, and therefore it worked normally after canceling, which indicates a malfunction in the LED
@@molodmhamed4066 good to know thanks,
Samsung replace my led screen but the new screen I am not able to feel the same color, or resolution contrast etc.. How should I convince samsung the replace led screen is not same as previous one..it is degraded quality
I spent hours looking through "fixes" for the power cycle situation with my Samsung SmartTV. This fix took as long as it took to just watch the video. I used a really small flat head screwdriver and half an inch of electrical tape. Works perfectly. This video saved me a thousand dollars easily on buying a new TV! Thank you!!
You posted this 10 months ago. Is your TV still working well, or did you end up buying a new one?
how did you figured out which cable to disconnect in the connector?
You have no idea how grateful i am for you and this video. Tried everything else and this did the trick, hope you have the best day ever you deserve it for all the pain you’ve relieved
You just fixed a tv was sitting here for over a year with simple step. Thank you
I found your video while randomly watching RUclips - I have two Samsung TV's with the "boot loop" issue. So I decided to try your fix on the oldest of the two which had been sitting in a guest room for about two years having been replaced by another TV. When I plugged it in, it was like a new TV - clearly, whatever internat battery saved the settings has died and the settings erase....lo and behold! The TV works! Re-connected it to Wifi, and it's as good as new. I have another, newer Samsung with the same Boot Loop issues, if waiting for a reset does not work, I'll go for your method as my plan B. Nonetheless, great video!
Thanks for taking the time to make this video. It solved my issue completely, and was very detailed. My only feedback would be to include the (extremely helpful) information about reconnecting the cable in the video, as not everyone checks the description or comments.
Today write driving home I noticed this exact Samsung 4k 55inch curved Smart TV. It was cosmetically clean and no noticable screen damage, so I grabbed it. And sure enough upon power up it just flashes Smart TV every few seconds and screen goes Black.
So finding your video is a true gift. Thank you so much, can't wait to try thisn fix. And I'll post my optimistic success. Thanks again. 👍
Thank you, thank you, thank you!!!! Fixed my issue and saved me buying a new tv.
Thank you! This saved me time going through each pin. I appreciate it.
great
Fantastic! Wonderful fix! On my TV, an UE55H7005 the BLU was pin #12.
Worked like a charm. Thanks so much.
I had 7 wires, 4th from the top worked for me! Thanks!
Thank you! This fix worked with my TU8000. 🙏
Thank you this worked perfectly!
Thank you very much for your help in fixing the samsung tv. I already repaired the second piece, which went wrong like this.
Worked perfectly, thank you so much
we are just having the same problem with our curved samsung TV! I am very happy that I found this video, going to try the fix tonight!
great
Did it work?
Loved the video, thanks for the information.
Wow it is working
Thank you very much
Found the pin and worked for me, but now the left half of the screen is darker than the right.. looks like I’ll still need to buy a new tv, but this will buy me some time until the Super Bowl TV sales! Thanks!
You LEGEND! Just saved me buying a new TV!
I think I tried every other fix in the book but they would only work temporarily before the issue would come right back, and a couple days ago it got to the point where the tv wouldn't stay on for even 1 second. But I just followed the instructions your video and it has so far remained on for 5 minutes, so I think you may have just saved me from spending hundreds on a new tv! Thank you!
great
Heey mate did you remove all pins until you found which one fixed it or is it the blu pin like in the video that is needing to be removed ?
Thank you very informative 👍🏼👍🏼👍🏼👍🏼👍🏼
Thanks, It also worked for me!
This totally fixed my problem! Thank you!!
great to hear subscribe. also after disconnecting that one pin go into settings then reset the tv then you will be able to reconnect that pin and the tv will be fine.
@@NewsonsElectronics how do this on a series 8 2020 samsung tv
@@Spotlessdelta not sure, does it have labels on the pcb
Heeeellll yeah! That absolutely fixed my issue, thank you so much, that's a lot of money saved from buying a new TV! cheers from France!
great and after you disconnect that wire go into settings and change the brightness then re-connect the wire everything should be back to normal.
@@NewsonsElectronics Do you think there's any risk of never pluging it back in ?
@@jeremys9283 I would change the brightness in setting then plug it back in. The reason being if you don't plug it in the leds will be on all the time even when the tv is in standby mode.
@@NewsonsElectronics alright thanks for the info!
@@jeremys9283 no problem
Hello Dear..Thank you very much for your help my television has the same problem as you had and I followed the steps in the video and the problem has been solved so far.. Thank again..🤝
I have a un55ks8500fxza with the same power cycling issue, but there’s multiple number PWM cables and a seperate “BLU O/F”. Would this still work? I tried removing the BLU cable and it didn’t work
Thank you for making this video. My UE40D5520 was boot looping, so I disconnected the BLU cable as you suggested and the TV then stayed on. This let me upgrade the firmware. Then I reconnected the BLU wire and the TV is now performing faultlessly. Thanks again!
Hello,ue40D5500rw not working
Thankx worked perfect
This helped me with my screen which had similar problem, the concept works, if it's not pin number 4,pin 3 works
Thank you so much😍
You’re awesome man, thank you for this. I’m going to try this in a little bit. Hopefully it works. Happy New Year!
same to you
Did it work? I am currently having the annoying thing where it turns on and off repeatedly.
@@ArtGuitarLTX yes it worked
@@ArtGuitarLTX nope, wasn’t able to fix it
@@ArtGuitarLTX - mine didn't work.
Thank you wery much. I've disconnected pin, then TV started working, then i do factory reset and then conneced pin back and TV keep working and then i've update firmware and now everything seems to be OK.
hey do you know can i swap bn41-01660 for bn41-01568 two models are ue32d5500 and ue40f6820?
DAMN! THANKS! that brings me one step forward! very helpful!
now the light works more stable. but the tv keeps turning on and off by itself..
i noticed some sond comming out of it rapidly hitting the "Exit", but still no image and as mentioned keeps turning on and off.. 😅
i have no idea about television tech! all i know, is how to identify the parts and discharge capacitors.. do you may have other solutions? 🙈
This is exactly what my tv was doing!
I haven't tried it yet… but I was so exited to see the identical problem that I'm commenting without much else to say.
K, then…
____________________________
I'm back…
Didn't work after all.
It flashed without the "smart tv" on the screen. I could see the back lights flash through the opened back holes/spots like you showed in your video.
I plugged it back in & the "smart tv" came back to the screen.
Guess I'm the unfortunate one here?
I have a tv samsung UE48HU7500L with rebooting problem. The power board is ok as when I disconnect the strip that goes to the smart board the back lights come on. The strip that goes from the power board to the smart board has got 30 connections. Should I disconnect one by one ang plug tv each time untei I get it fixed ??? Is this the best way??
holy shit it worked, thank you so much mate
glad I could help.
Tnx This fixed my problem 40f6450
Anyone know the size of the tool to open the tv? My 65 in. Qled has weird looking screws
After removing that cable, the tv booted but after some time it dimmed and it shut off. Now the tv blinks the red light 6 times and doesn’t boot up anymore.... any suggestions?
Cześć mam model ue55nu7023k dioda mruga dwa razy tv się władzy do kogo Samsung i gaśnie i tak w koło czy Twój sposób pomoże ?
Very nice
My cable is 26 pins. It says the 26th pin is BLU ON and the 25th pin is PWM.
Should I unplug both?
Thanks!
Thank u so much.
no problem just change the brightness setting back the you can reconnect that pin
Same problem with UE49KU6100K, I downloaded the wiring diagram and disconnected pin 8 (PWM_DIMMING_OUT1), but nothing, it keeps looping on/off... Unlucky.
Thank You So Much!!! You Have Saved Me $250.00 That I truly can't effort at this time. My TV went out a week ago. I had been calling Samsung for HELP with them ending with a Service Fee of $250.00.... Now, you have shown me a FIX FOR FREE!!! Thank You Again, and... May GOD BLESS YOU!!!
Companies are only interested in sales not repairs
Hello sir,
Please reply me as earliest as you could please
I tried all the steps you outlined the backlights and power supply are okay but when I pulled out that wire you showed the problem still persists…. My tv is Samsung smart 55” MU6120 class. Please help. Thanks
UE46F6100AWXZG pls help me I have exactly this issue on my Samsung smart tv, pls is this video applicable in all model of Samsung smart tv?
Worked for me thanks...what will be a permanent fix?
Just subscribed to the channel! This video was super helpful, but I do have a question. I have a model UN55D6420UFXZA Samsung TV, and there are 20 wires going between the power supply board and the main board. How can I identify which pin is the PWM BLU? Thanks in advance for the help!!
should have markings on the motherboard.
The real solution is to never buy a Samsung TV. I have a different model with a similar problem that started just after it went out of warranty.
Mine too. That’s about how it works
Same
Same here, 4 months out of warranty
well mine did it recently and I had it since 2017
Same now
I have a problem with my 8k qled samsung will this work please ?
my MU8000f reboots at around 10-15mins after turning on, then continuously reboots every 30sec-2mins after the 1st reboot. Is this the same issue with this model? I have no issue with lines, blank screen, just turns off(fades black) then turns on again.
sounds like bad backlights, you can search in my channel for backlight repair to find out how to fix it.
you remove power on signal,how the power supply produce another voltage with out power on signsl
Desde Mexico te agradezco, quedo bien chingona mi TV
Bro thanks
Work at my UA55ku6000k? Can i try
There are many issues with these later model Samsungs that cause power cycling. My 70" is doing this and what ive seen online is some sort of issue with the LED array. Some people are taping the ribbon cables but in comparison from mine to what they show, I can not isolate the issue from 1 side of the screen to the other. I have fiddled with it enough to get it to work and have found a couple lines on a ribbon that I can block that allows my screen to function with normal coloring but do you know if the issue you found could be related??
I don't think it is related on is to do with the backlight one is to do with the lcd panel
I was given a tv to fix and it has a bootloop issue and apparently it was stuck in a grayscale before the bootlooping occured. What exactly did you do??
thank you for your video .i tried your method but it still restarts and the standby led keeps flashing.
really helpful video. One question though, what did you mean when you said that the backlights would still be on? would i have to unplug the tv from the wall when its not in use ?
see if there is a glow when its turned off if so then unplug it.
Hi, I pulled the pin as you have shown. It keeps the TV on and I have sound. Both back lights are working but I have no picture. Any thoughts?
check connection to tconboard .mainboard
Can you help me please? My 55" Q60R (2019) is restarting with 2 standby led blinks (power supply issue error code). I plug it in, starts to boot, then it fades to black from left to right like there is not enough power to run it. I swapped the power supply but it does the same. Do you think this could work or shall I look around the buffer boards under the screen? Many people have this problem with no luck so far. Thanks in advance!
i have a q80r with exactly the same problem 2019 as well, will turn on display the qled symbol then fade
cant find the original receipt so samsung are not playing ball would love to know if you find a fix
nice Thank u
no prob
Thanks so much for this fix! Did the trick for my samsung UE50KU6000 giving it a 2nd life. But what could be the root cause of the issue? Is the cable itself the flaw, so replacing it maybe also solves it?
its your backlight one of the leds is bad
Hmm. I've got a 46" Samsung smart tv with backlight flicking on and off. I cut BLU_ON wire in slot number 20 however it is still giving the same behavior.
Edit: Ok I kept snipping wires from the power board to the main board and eventually one of them fixed it. It was either SDA_LED, SCL_LED or OD_ON/OFF. Now the backlight turns on turns off briefly and then comes on and stays on. Unfortunately I already ripped another ribbon connector off the board from not understanding how it was connected. Maybe next time.
Also try unplugging connector from the backlights.Shine a torch into screen and if tv stops power cycling and you can see and image on the screen when you shine the torch into it then you have an issue with the backlights
already follow all step...but still not working....:( is it possible if replace the new cable
Hi,
it was worked but after 4 weeks tv is rebooting every time. On this same mainboard or on another one. With pin in connector or without. Other suggestions?
it means your backlights are damaged, one of the leds is bad, check my other videos on my channel on backlight replacement.
i have a UN55KU6270F its doing the logo on off like my backlights work or stay on with the power supply connection to the mobo disconnected but im wondering what the error appears to be comming back from the mobo is the mobo worth replacing that is it mobo related im hoping to get into the menu and turn off all the remote and wifi features hoping that clears up the problem or reflash firmware currently i cant get to the bugger to play with the menu p.s did you plug the pin back in after you got her running ?
Solo haz lo que él hizo, yo tengo el mismo modelo que tú 😊
It didn't work for my Samsung UE49KU6500, the power cycling stopped but no image...
I have Samsung UE55ks7000u with similar problem what id the cable number or the theory cant work for that model
it may not work for all models, your issue might be the backlights, see my channel for repair videos on that
Hey,
First thanks for the awesome tutorial very simple to follow. Unfortunately it didn't work for me. But I noticed that when I disconnect the ribbon cable connecting the mother board to the leds, the power cycle stops and I get sound on but of course no picture. I started adding duc tape on each of the ribbon cable metal pins until I narrowed it down to one particular pin to cover and get the power cycle to stop but still no image. Also important to mention that with the pin uncovered during the power cycle the Tv lights on and displays the Logo before rebooting after like 3 seconds so Im thinking display cannot be totally broken but not sure and I have no clue what's the issue, any ideas ? Your help would be really appreciated, the tv is a 1000$ one barely 18 months old, would be a waste to throw. Thanks in advance for your help
buy an led tester to test the backlights.
@@NewsonsElectronics Im no expert but if the TV logo is displaying I really doubt it's a backlight issue. Anyways I will keep trouble shooting thanks for the reply
@@alasoua1492 it will display the logo because it ramps up the voltage if it detects a faulty led it turns off check ruclips.net/video/IC21n9YX5nU/видео.html
@@NewsonsElectronics Thanks for your help. It makes sense what your saying, honestly I feel it's beyond my skills, but Im gonna give it a try at this point nothing to lose the tv is going to thrash otherwise. Is there a particular led tester you would recommend on amzn ideally ?
What model tv do you have?
Does it going to work in other brands like nikai? Brought in KSA but now it keeps on restarting
not sure
Do a software upgrade
I have 16 pins for the pwm and i tried each one and none worked.
I did have the same issue with my TV (QN65Q60RAFXZC). The loop was fixed by applying tape on one of the panels. But now I have a totally blank screen. The remote works now and I can hear the TV go on and off. Wondering if you have any suggestions regarding that.
i have same problem with QE50Q60TUA
What is the cord called
why you disconnect pin4 not 6??
any idea whats wrong with my tv. it keep restarting 5-10secs, Samsung logo doesnt even showed on tv yet but restarting lol
Never did solve my TV's issue moving it around so much eventually lead to a screen break. This did seem to stop the restart loop but the screen image didn't come back on. Of all the Fixes this was the only one that changed anything at all, so that's something at least.
TV model was un58mu6070e
Thanks for the video though.
glad I could help
Anyone works this method on any QLED models? Ive got same issue with qe50q60tua
feel free to add a comment below
Will this work for my Samsung QLED TV (model QN65A60RAFXZA) that is less than 2 years old and not watched a lot? Also, is this something anyone can try to fix, or do I need some background in electronics? Thank you!
it could work not sue, just be sure to unplug before taking apart and make sure you don't touch the capacitors.
Hi Sir
I have same problem the TV goes on and off automaticaly . But my system is UE46F6670SBXXU
THE CABLE CONNECT TGE POWER SUPPLY IS 10 PAIR BOTH SIDE THEN WHICH CALE TGAT I MUST REMOVE OR DISCONNECT Sir
Same here ! Any updates ??
Hey please respond..I had two TV's..one started to on and off, now bought a new one and it is doing the same..what is the problem here? Is the switch faulty?? Please respond ASAP thanks a ton.
its going into standby, it could be your backlights this can be tested with and led tester costs about $30 on amazon
The technician said the internal circuit will change..is it so?
@@videotutorialsss change? Not sure how? there is a charge so be careful.
My UE55KS8090 has also a bootloop problem. I check this solution on my TV (randomly check all cables), but no sucsess. A mainboard change also does not help. Any idea?
I bet it's the backlight seen this before do you have a n led tester?
@@NewsonsElectronics Thanks for the answer. Sadly i have no led tester. I will have a look to get some.
@@polini0 here is a link amzn.to/2SCcEe8 , led testers are worth having
@@NewsonsElectronics i have used this method ruclips.net/video/pfrRhw7-ZII/видео.html and found a pin on the displayboard that has a problem. So i blocked this and the TV ist starting fine.
On all Samsung Tvs you can unplug the main board from the power board and it will turn on the backlights automatically so you can move on to the next diagnosis step
Hi. Does it work for Samsung Smart TV... UA40D5500RR ? I see the brown board have 14 pins. #2 pin for "PWM_DIM", and #6 pin for "BLU On/Off". Do I do the same #6 pin like in your video?
it should work.
hi, it's not work for me😭
Mine is a 14 pins. I remove each of them one by one. But still that did not resolve my problem. Any other suggestion please?
buy an led tester and test the backlights
My samsung 50tu8000 had also boot loop, so i tried your paper trick. Now it started up with music and sounds but no picture. Then i removed paper and connected the flat cable back, but this time i disconnected the flatcable between the 2 display control boards located at the bottom. Now the boot loop was gone , but still no picture. Then i cleaned the disconnected flatcable and reinserted it. This was the fix, tv started up and i got picture!. I think that due to very low currents and warm temperature, the contacts oxidated a bit over time.
Hi, I have the same issue and I found the solution, maybe it works for you too. ruclips.net/video/PMy5-S7Ilqo/видео.html it's in Spanish, but if you pay attention you will know what to do even if you don't understand. I hope it helps you
I have two TU8000 50" tvs that boot looped, blank screen (blank/empty, not black and/or dark). I tried this, and ths bootloop stopped, but I still was left with a blank screen. What ended up getting both screens to work, for me, was putting a piece of masking tape on the BACK ( Not the side with the contacts) of the ribbon cable going from the mainboard to the panel.
Now I've got both to work, but both have very thin horizontal lines in several places
Please explain. Where back?
Tu8000 is the worst serious. Even i have the same issue. Masking tape solved it but i have a thin horizontal line with abit of a blinking led
My tv is a bit older-2004. When i got the back off-the connector has more than the 6 wires. So how do I know which one it is? And after watching other videos-can I get shocked & how to prevent that (other than unplugging)
model code: LN40B530P7FXZA
Thanks...need reply asap PLZ!
note sure for other models but if you tv turns on and had a black screen it might be because of your backlights. checkout ruclips.net/video/SX33DExTSNs/видео.html&ab_channel=NewsonsElectronics
I have the same TV as yours. I fixed my by putting a tape between the cooling padding under the mainboard. Under the logic or mainboard there is a cooling pad that transfers the heat from the voltage regulators to the chasis via the padding. Unfortunately the padding that sticks under the board introduces liquid to the circuit and shorts the main board as the padding heats up The solution to fix the problem in this TV is to clean the board to which the padding sticks with paper towel to remove the liquid glue from the padding. Then afterwards, put a duck tape with the sticking side facing the padding. The duck tape should be cut as per the size of the padding. This will make sure the heat transfer padding does not transfer the glue liquid to the board, and it wont short the circuit. I fixed my LN40B530P7FXZA this way. Make sure you unplug the power cord and wait for 10 minutes before working on the board to discharge the capacitors on the power supply.
I have an issue with my TV and I have a video on how the TV restarts its self
I think its the power supply but I want you to see it and tell please
How can I send it
I don't think it is the power supply use an led tester to test the backlights.
Power on/off turns on the power supply board and in turn the tv.pwn blu turns on backlight unit. test the pwm blu pin on power supply board and if you are reading less than 3.3v then problem is in main board.If 3.3v to 5v dc is present fault will be somewhere within LED inverter on power supply board or more than likely a defective LED strip.By pulling the cable out of the connector you are simply bypassing the fault protection and supplying direct power to the LED'S.the issue you are having commonly leans towards defective led strips
yes but this will get it working until you have enough money to buy a new one, cheers
@@NewsonsElectronics replacement LED strips and power supply boards are cheap and easy to replace👍
I have issue with my tv . It kind of want to start but goes off . Every 20 sec. Wants to start but goes off .
Do i have the same problem like in your video ?
try it and see if it works
Didnt work for me , what should i do next ?

Is mine just a bad panel because i'm not getting a picture? I've replaced main board too. PLEASE PLEASE PLEASE HELP... COSTING ME LOTS!!!!!!
either backlights or tcon board
@@NewsonsElectronics Would it be the main board if there is no tcon? And it looks like all the back lights are good. But thats from looking through back panel holes.. Can I test led's without taking screen off?
@@NewsonsElectronics If some of the backlights are out & I fix them.. You think I will get my picture back? It looks like I have a shadow area so maybe some are bad. But even when there all bad you usually get a picture... Seen w flashlight. Blue screen for me

I have try it don't work the screen flicking ans restart now
is it the same version of tv?
I had this happen to me awhile back after cleaning the tv screen. Call Samsung warrant repair, and 2 or 3 days later day he shows up to make the repair it worked. The fellow could not explain why it would have don't this. It's now happening again.
it worked partially for me now it doesn't turn of immediately but it keeps restarting , but without turning off the backlight , any idea of what might be the problem ?
adjust the brightness then reconnect the wire
how can i can i do that ,because it doesn't show any menu options it just shows QLED logo them restart but without turning the backlight off
