SAMSUNG UN70NU6900F NO VIDEO FLASHING SCREEN FIX WITH PAINTER'S TAPE, SYMPTOMS NO PICTURE, BLUE SCREEN, FLASHING SCREEN, UN70NU6900F FA01, YA02 REPAIR. FIX NO PICTURE ISSUE.
Omg you are a life saver. Our t.v went black and we followed your video step by step. It has a little grey or pink still on the end of it but we rather have that than a black screen. We are able to still watch our t.v. Until we get a new one. It was all about playing around with the tape size covering those little slits. You saved us 300 dollars to get it fixed, plus we never fixed a t.v. before. Thank you again
Like many, I too am only coming back here to express my gratitude. I replaced a 60” LG plasma that served for 11 years with the model on this video, so when it stopped working after less than two years I was furious. THANK YOU for sharing the knowledge and making the steps in the video easy to follow. FYI: I only blocked traces 13-16 from left to right on the top ribbon and voila…like new again. The true fix is to buy LG from now on lol.
I just wanted to say thank you. I have that same model and that fix worked. I made the tape shorter and shorter.. I think I only have 2 or 3 pins covered and it is still working. I do see the color difference but it is way better than throwing it in the trash!! You are awesome and thank you again!!!
I fixed my neighbour's TV .. Exactly how You demonstrated... Sincere thanks!! I would've loved to send You the money but it isn't Me but I am so happy I could help someone 600$, just because of Your video. Keep up the Good work and I am sure Karma will get You back the compounding return for Your efforts!!
Awesome! Thanks to your video and one of the commenters below I was able to get my tv working again and it looks perfect, just as it was before! Thank you! 💪😎
Thanx so much for the video. This really saved my 75 inch Samsung and im gonna fix my 65 inch samsung later today. This really worked out well. May GOD bless u a million times
Just took this exact same model tv out of garage(headed to the dumpster), tried this trick and it worked!!! Thank you for saving me from having to buy a new tv.
TOTAL LIFE SAVER!! YOU DA' MAN. IT TOOK PACIENCE AND TRIAL AND ERROR BUT WAS A SUCCESS. THOSE OTHER PEOPLE'S TUTORIAL VIDEOS DID NOT WORK, AND I WENT THROUGH A LOT. YOUR A GENIUS. THANK YOU
Thank you so much you are the best I like the way you explained it is very clear and helpful I have the same problem with my tv Samsung 70 inches I was thinking to thruway but because of you I tried to follow your because I can’t afford to pay somebody to fix it thank again and god bless you.
Dude, we found this TV on the side of the road with this same issue, and I fixed it in half an hour. You are the best thank you!!!!!!!! New 70inch TV for free!!!!!
This is by far the best solution. I used scotch tape. I will try to do the same to the other ribbon to equalize the screen. Thank you so very much. I will post when it is finished.
I was lucky enough to have this work for me on my 6 series 50 in MU6300. I didn’t have painters tape. scotch worked just as good. I’m very grateful for the information. The t.v has been broke for literal years
Thank you so much! Our TV is only a few years old and one day we turned it on and we had sound, but no picture. We followed the instructions in your video, and it worked! The color is still not even, but at least we can see to watch it again! Thanks again!
Merci beaucoup pour cette vidéo qui m'a permis de ne pas jeter ma tv Samsung. J'ai pu la remettre en marche alors qu'un technicien affirmait qu'elle était bonne pour le musée des ancêtres disons la poubelle même. Merci encore.
I've got a Q80A so it's a little different than this one, but this is the best explanation in the thought process of actually figuring out what's going on this is so much better than 99% of other people that post TV repairs. Like this video will make it to where I am better at figuring other stuff out too. Thanks bro!
You the man bro, tv TU8000 was black going on/off. Came across your video last night. Tried tape enough to see settings eventhough black line in middle but I reset tv in settings, took all tape off of ribbon and connected it, them bam perfect. Thank you, subbed to you
I would like to say thank you very much for this well explained video. I tried it on samsung 55in and it brought it to life again thank you and God bless you.
Great troubleshooting walkthrough, and many thanks. Had this issue with our samsung model QE50Q67TAUXXH. Seemed to be a metal part of the speaker unit that was touching something it shouldnt, and taped this off. Tv working perfectly again without having to tape off the cable.
You sir are a legend!!! I got the same model. followed your steps and i got a picture!! I narrowed my ribbon cable down to two pins and now have darn near perfect color. a million thanks
@@KC-lm2tx i added tape just like he did. i cut 4 pins worth at a time off the left side till it got worse than non cut. I then moved the tape to the left till the picture got better then i cut on the right side till i got a great picture. i couldnt tell you exactly the pins. i dont want to take it apart again lol
I really appreciate this video, my husband and I were about to get rid of our tv but came across this video. We followed each step and boom! It started working again. You save us some money lol!!
This video REALLY helped! I had the same exact problem, followed what he said and got my tv working again. Only problem is, the left side does not have great color. Anyone at all, feel free to reply to me with suggestions to restore proper color
Thank you great video been saving this same TV for a year hoping to fix it one day. Took me a couple tries and it was the other ribbon cable but worked great .
I just checked out your video. Thank you! I Was able to completely the quick fix on my Samsung 55 inch tv @ 240Hz I also got a mainboard and a T-con board as a back up for my tv (Due to I did not want to trash my TV
I'm just here to add my thanks. I have this exact model with the same problem. Of course Samsung and Best Buy were no help at all. With your help I was able to salvage something that would otherwise be completely useless. Thanks a lot, man! I really do appreciate it!
Huge shout out to you have this exact same model been sitting in a corner for 3 months because of this exact issue i did your tape method and worked came right on. Decided to order a new one of those for now but really cool i was about to just take it to the dump. Thanks big time!
Just so happen to come across a 75” tv someone was throwing away I took it call around to see approximately how much would it be to fix. Something told me to do a little research on RU-vid and you popped up. I followed all the steps just like you said and now the tv works . Thx man
I want to thank you because of you I was able to fix my TV who knew what painter tape can do for my Samsung I had to do 13 pin from the right and had to cover about 6 of them. THANK YOU THANK YOU THANK YOU
13 pin from the right mean when you lift the ribbon up you count from the right side? I have the same issue but tried to cover pin 14th from the left for both ribbons but the TV keeps on and off
Update.. I purchased this same model TV from someone for $50 and was able to fix it just like you demonstrated in the video. It looks and works like new with the acception of some extremely hard to see faint lines on left side of the TV.
THANK YOU WORKED PERFECTLY. my tv has been sitting unused for about a year. Coukdnt find any solutions other than the obvious unplug it and plug it back in, i was about to get another tv and decided to try to just replace the boards, i found this video when i looked up the part number and saw it had the same issues, did everything step by step and it WORKED
My dude!!! I got it on the first try! This guy GAVE me this tv and your video helped me fix it! Aside from the mild green tint on the upper left side, this tv is flawless! My sincere thanks to you!
Awesome video! It got my screen working again but half is black and white still, which I can deal with for now! I just saw the comment about getting all the color back so I’ll have to try doing that but I’m just excited the tv works again! Thanks for the content!!
You by far have given more information than multiple local tv repair places and anywhere online. My tv is having the same exact issue, I’ve just decided to wait the shipping time for the new ribbons. Thank you so much for the info!!!!
@@bbbri05 I’m still waiting for the ribbons to come in however currently as a bypass I have the TV set up with the back panel removed so when the issue occurs I can tap the connections for the ribbon cables and the tv will turn on. Should work at least as a temporary solution but the issue is definitely the ribbons
Ty for your reply, we just took off our back panel to see if ours reacted the same as the one in this video it did. Did you put the tape on it for the mean time ?
@@bbbri05 no I didn’t do the tape because I didn’t want to trouble shoot that many times to get the right picture so I just tap the connections for the ribbons. If you want to add me on discord or whatever you are comfortable with I can walk you through the process that I do for the tv
Thank you for this video D Double J. I got it with a 6MM piece of frogtape starting on the same pin you showed. I also used a 6-outlet with an on-off toggle switch to kill power to it between tape trimmings.
Thanks, It didn't work for me on that belt but after I checked your video it gave me ideas and I tried with the other belts and it worked lol it was actually the belt for the right side of the tv I covered 2 pins and found the problem, I tried to cover more at first but I was losing too many pixels and showing lines so I tried pin by pin lol it wasn't easy but I found the 2 causing the problem and now unless you get super super close to the tv you can see that some pixels aren't working but from 2 feet away you can't notice anything lol
I have a slightly different model and I was skeptical at first but then I went and got painters tape Cut it approximately and put it on and it workeddddddd. Didn’t even cut it more after because I was just happy it works and the color is good tooo Thank youuu
I got this 65" tv for free off of Facebook market. I came home and tried a few things other RU-vid videos had suggested. Then I ran into your video and it worked. I got it right the first time. I can hardly believe it. I don't understand what I did, but it works. Thanks a lot.
Great Video! thanks DJ I don't have sound after unplugging ribbon cable, either one. Can a Main board fix this? I already replaced the power board stupidly. I'm just learning!
I've just come across this exact same problem on a Samsung 55" TV. I went through the typical tests including taping off some of the lines on those ribbon cables and the TV would do as you have shown in this video. But, further testing (many hours of testing) showed that on the circuit board at the bottom of the screen (the one attached to the screen that runs the width of the screen) has some diode packs. One of these diode packs was getting hot. I removed the device from the circuit board and now the TV works fine. I found two shorts within the diode pack itself. Pins 1 and 10 were shorted and pins 5 and 6 were shorted. Without the schematics (and since I didn't want to try to reverse engineer it) I can only make assumptions on what these diode packs did. Since the TV works without it, I assume it's some sort of back EMF prevention as it also appears to be installed with reverse polarity. But I could be wrong about this. The part number on it is 4268H but I could not find any datasheet for it. It measures about 0.5mm x 2mm. So far, the TV is working without any apparent problems but only time will tell if missing this part will impact something else in the future. At the moment, I'm keeping an eye out for a similar TV for salvage to replace the part with. I hope to put out a video regarding this repair soon. But it's on a very long To-Do list.
Thank you for sharing this! It fixed our TV as well! We had to cover roughly the 12th or 13th pin skipped a pin cover 2 more roughly skip a pin and cover another to get our picture to have full color back and no lines. It's not completely perfect but very close. It is usable and way better than having to buy a new one.
What I’ve realized is most of these Samsungs are Covid stimulus check TVs. I got one too with the same problem. Mine started cycling after a 1 second brown out. I found the short in the cable and now it’s on with sound, but still no picture. I’m going to watch some more videos to see if there’s something else that can be done but I’m afraid I’ll have to purchase another. It will never be another Samsung though. They should be ashamed of this issue. Edit: your video helped a lot! I got a picture now. Unfortunately, half the screen is a different purple hue. But, that’s the left side of the tv and the original issue was with the right half where I put the tape. That side looks excellent. 🤷🏻♂️. Guess I’m not quite done fiddling with it yet!
My Samsung QE55Q65RALXXN was re booting every x seconds. (Bought 2019) I installed 3 mm widt piece of paper in the contacts from the lower flat wire. My tv looks exact the same as in the fantastic video. Thanks . Everything is working perfekt again. I only miss the stand by light. In 1 of the video,s you explained that all the voltages to the mainbord do not get over 12.8 V dc. Should I be afraid for fire ? The TV is already 5 days in use since repair
thanks for the video. my TV worked and I was able to get the same picture quality as yours. I removed the tape the next day to see if it would work, and the screen was back with all the colors.
Another question, 😂. As you have helped me tremendously understand this TV. What if I disconnect both ribbons and still getting blue with no sound. Would the mean it’s the main board?
Hey DJ. Thank you so much for this video! Definitely worked! I was wondering if replacing with a new cable would bring the color back? Wasn’t sure if the problem lies within the cable or the board. Thanks!
From memory it was 5 or 6 from the bottom, it was just trial and error really. Lost count how many times I moved the tape and switched the set on/off, but stick with it (no pun intended), touch wood, our TV is still working and perfectly watchable, just a slight (very slight) colour mis match
Awesome! Worked on my QN75Q60RAFXZA TY!! However I have two questions. When I unplugged either cable it stayed on… any ideas on why? Is there lcd issues on both sides? And two, any main reasons why the tvs are doing this so early in their lifespan? How long you think this fix works for? TY for video .
Hi bro I need help please I have 58 main board just and it it self no display no right when I put 55 curve board come on no pictures backlight it comes on so how can I figure out which one is dead please I need help
I have same tv and same problem. What I did if your facing the back of the tv was remove the ribbon from the bottom left side of the panel that runs down from the bottom of the main board. Waited for the tv to light up and sound to come on. The tv stayed on then I plugged the bottom left ribbon back in WHALLA!!! FULL PICTURE FULL COLOR NO LINES. Downside- as soon as you turn tv back off and on again you have to remove cable and put back again. I'm going tontry your process next but trying to avoid loosing color or reducing the lifespan of the other processors if their working double time due to the tape method. (Do you think that is true? Reduced life span) My other idea is to get an extra 96pin ribbon and a double sided femal adaptor and hang both ribbons out of the bottom of the tv so I can easily access and remove the ribbon connection and plug back in after it boots back on.
@@BoulderHouse I used you method it worked great I have my TV on a wall mount that pulls out I just cut a hole behind the ribbon on the plastic to access it
I have a 65nu6900 that has a grey screen. I remove one of the end lcd driver boards out of the circuit and i get proper 16.7V on the capacitors but still grey screens with no video. The tv sounds correct for the setup screen but cant coax an image out by covering pins on the ribbon. The lvds cables are very narrow, half the size as the ones in your video. I suspect one of the COF are bad as i see some subtle lines at one end of the panel. Not sure if i can coax an image outnof this one. Any thoughts before i start cutting traces?
Dj Johnson I love you!!!! Thank you a billion times my brother. I ordered main board, power board and tha didnt work. Then i see your video with blue tape and boom my tv is working again. 1000 star video brother keep up the great work !!!
I have the same tv with the same problem. It was working just fine, until today. I came across this video and you explained everything so well. Thank you! Now I’m going to try and fix it myself.
@@EARTHKEENING yes color is fully back. I just have small horizontal lines at the top. It doesn’t look that bad. Gonna try to get those lines to go away. Are you having the same problem?
@@Wsulphur my tv problem is flashing very dim blue very fast and the stand by light flashing it’s Samsung 65” I took the cover out today and I found only 1 ribbon cable from the power board to the main board. I didn’t do the fixing method in the video since I saw just 1 ribbon cable .
@@Wsulphur I wrote to hamil he didn’t reply, my tv is different it’s un65j6200af btw the fix in the video is not strictly for the same model it should work for any Samsung with 2 ribbon cables .
I tried it and it works perfectly in fact the tv seems a bit sharper and more responsive. However, after the procedure, one side of the TV seems a bit darker than the other. Is this to be expected?
Thanks for all the informative videos. I opened up the back and removed the tape and the tv worked without the color imbalance. I did lose 6" of screen on the left side. How can I correct that problem? So maybe you can try that and see if you get the same results. Thanks again.
I purchased a mother board and power board and my Samsung tv still wouldn’t switch on so as a last resort stuck a piece of tape on the connector and it all powered up again.no lines colour perfect so I want to thank this genius of a man for I was about to throw my tv in the bin.😁
you can also disconnect the ribbon cable to the lcd then when the tv is on reconnect it and you will get full picture and color. might take a couple trys to get iit right.
That's cool! I have a Samsung UN50NU6950FXZA which has nothing on the screen I do get a sound there is a red light that flashes. What do you think might be the problem.
Great video! One quick question. Is the problem that is occurring due to the ribbon or the main board? Say if I decided to replace parts instead of covering pins which of the two is best to start with?
You saved me a lot of money! I had the exact same problem on Samsung Q60 series TV and using a tape after 12th pin, the problem resolved and TV stopped rebooting, so far I don't see any lost features nor any leds turned off on screen. Thanks a ton.
