I just fixed a three-year-old Vizio M558-G1 by applying the opposite logic on the image vs control lines. Vertical lines dominated the picture, and removing the TCON cables revealed the problem to be on the left-hand side. From your video, wherein you pointed out image data is vertical and control/timing data is horizontal, that told me I had an image information issue. Before then, I had no idea which pins to cover. That data limited the shorted vertical image processor to one of six on the right and I inferred that meant six control lines. Covered them all, and the picture came back immediately with a shadow in the lower left corner. I then started working one at a time, starting with line 6, then 5, and *bingo*, the picture was back with no flutter. I put it back together and it has been running perfectly for about four hours now. You just saved me $1,600 I was getting ready to plunk down on an LG G2!! ❤️

@@FrugalRepair I saw some guys on YT repaired it by cutting the connection on the board it self instead of using tape. I have a Samsung I got for free a 42'' inch or so, bought a Panasonic for 60 euro's a good one and 12 euro's for the remote. I have the feeling older tv's lasted much longer than the flatscreen do, they are just a throw it away. My mom bought in the 80's a Schneider that had an ITT tube, worked for 17,5 years constantly on, many people told us, it was trash, well known brands were gone sooner than our tv set.
I've bn looking for a clip like this for yrs. How I haven't stumbled across it until a couple days ago I do not know. I fixed 2 50 in. TV's with many horizontal lines and i just had put them in the shed, did not have the heart to throw out. Also, scored a 65 inch off of marketplace for free because their cat had knocked it over and it was also horizontal lines. You are a gem 🙃 thank you for this wonderful video 🙂
Dude! Thanks for the explanation! Picked up a free Samsung smart TV and watch two videos showing to use tape but they didn't show the fault finding process, now I'm off to give it a try.
Extraordinaria forma de explicar una solución y, al mismo tiempo enseñar como funcionan las pantallas lcd. eres un buen ser humano. Muchas gracias God bless you
I waited for 2 years to find a solution for my 55EX720 3D TV double image problem, and today I managed to fix the issue, as suggested by using a tiny strip of cellophane tape. Thank You.
Thanks so much for making these videos! I looked around for repair insights like this back in march, but glad I kept the broken TV "just in case". Also, your continuity test "swipe" at around 5:25 was really reassuring, as I would've worried I could short something else out by just probing those tiny traces at random. Thanks especially for that!
@@FrugalRepair Hey bud, my TCL qled panel got damaged , my son threw a hanger at the screen, there was a crack and white vertical lines about 2 inches in that region, after a month of r&d the tcl person gave me a about 200$ quote, now my question is how can i figure out whether he has fit a qled panel or a UHD panel
@@ktolwal If TCL quoted a price lower than new purchase price of an entire similar TV, there must be a misunderstanding. LCD panels always cost more than a new TV especially considering shipping and installation. To answer the question, There is only one specific panel for a given TV, no substitutions.
FINALLY the Louis Rossmann of LCD TVs!! Your last video troubleshot a TCL LCD, I just had a 43" 4k TCL flicker then the backlight seemed to fade out on the right side. I see the image across the entire screen however it gradually gets darker the further to the right. Any troubleshooting suggestions or can you perhaps create a video on how to repair / troubleshoot backlighting on LCD panel? Big thanks, thumbs up and sharing your channel.
I feel honored being compared to Louis Rossman. Thanks for the comment and share! Did you get my pdf? I have a led backlight suggestion in there. Sounds like you need to replace some of the LED modules. I’ll create a video sometime, I’ve got a pile of free TV’s people have given me.
@@FrugalRepair I received the link, thank you! I've tried dimming the brightness as suggested but the dimmed side is dropping in brightness as well. I would expect the bright side to match the dark side when decreasing the brightness at some point IF a backlight LED was out. When the startup screen appears after a hard restart the entire screen is PERFECT for 2 seconds, then the dimmed area appears. Possible power/short issue I wonder? Any suggestions would be awesome, thank you.
Good to hear you got the link. What you are describing sounds like there is at least one shorted LED module on the darker side. The reason you get full brightness at boot up is that the power supply ramps up the voltage all the way and then the short circuit happens to take it out some others LEDs (maybe it's localized to one of the LED strips).
Omg it worked i cant thank you enough i really wanted to buy a tv for my room but i spent my money on a pc i recently got a free lg 32" tv from adverts i spent 2 days troubleshooting and now it works you really inspire you i cant thankyou enough for your info i want to do electrical engineering or repair when im older and i have leared so much from your video keep up the incredible work
Amazing video man! I really appreciate the time and effort you put into this. I spent way too many hours on this when you summed it up in mins. Other videos wouldn't go down to the details that you did, leaving for an incomplete understanding. Thank you.
WORKED!!! Thank you so much. I had a 58 inch Hitachi tv that had a suspected bad tcon board. Then my kitchen JVC Fire Tv panel board packed up. Not worth fixing the JVC but I used the Tcon out of the JVC as it was the same part number and make but version 4 rather than version 1 that was already in the Hitachi. Then it all loaded up (it had been dead in the garage for two years!) but it had the horizontal lines. Took off each cable and figured it was the right side. First attempt of tape in the middle didn’t work but moved it right a bit and second try worked! It’s not 100% but it’s 99.99%! Now I have a very happy wife as she can watch Strictly in the kitchen. Happy Wife…Happy Life!🤟👍👊
This actually worked for me! Thank you! I had a single pixel-length black horizontal line a third way down from the top of my Samsung TV, that faded as it went from left to right. After placing a mm of electrical tape on the 15th trace on the ribbon connected to the TCON board, it got rid of it. The only complication like you mentioned at 7:20, I have faint lines from top to bottom accross my TV, but they're barely noticeable unless I am standing 3 feet or closer.
@@camokid95 im working on a QLED with a single line across the screen. I don't want to block off half a dozen tracks and loose picture quality since I reason that is likely a single trace that's the issue. How does your picture look with your fix? Do you see any diminished picture quality in the trouble area?
@@therealeffingdeal It appears diminished, but not that noticeable from a distance. You should only block the trace relevant to the line that's a showing the dead pixels.
just used this method on an Insignia 50" 4k tv with horizontal line across it and it worked...I just took a small piece of tape and just moved it around and i found the spot....Thanks
Man !!! You are legend ! Ive been banging my head with lvd ribbon cable, even swapped tcon board but couldn't figure out whats going on. Your explanation answered my question..and ur method worked 100%. For me (Samsung 50" smart) it was the last set of 7 lines in right ribbon cable (if looking from rear of TV) I did like 20-25 hit and trials of 7 lines wide tape and finally hit the exact set of lines ! Thank you so much brother, you earned some prayers from me :)
Thank you very much for this video. My LG 42UB820V developed the same fault as described in your video. I located which side was causing the issue and identified the clock pins (there was 8 from pin 3 to pin 10 on the ribbon). Small piece of sticky tape over the 8 pins and all back to normal. What an incredible fix, sheer genius!!
Bro, this basically fixed our TV. We taped over the left-most 4 pins on the left side ribbon (looking at the back of the TV, oriented right side up). The only down side is that it seems the red LEDs are affected by this. There are horizontal wavy patterns every time a lot of red is shown on the screen (like in Netflix, for example). Either way, our TV literally randomly started showing lines and color stains, and this helped us completely get rid of those, so our TV is watchable once again. Thank you so much, dude!!!
@@FrugalRepair It's so appreciated. We noticed when watching shows now that the right side of the screen is really missing a lot of red in the color. It's like when character move from left to right, they get dreary and depressed as they lose their vibrancy haha. Might do the same thing with the other side of the screen so that there's at least no difference. Do you know why this would happen?
I hope you’ve enjoyed the videos! Haha, I have lots of TVs. But some are friends that I fix for them, some I might give away, some we keep, some I might sell.
Thank you for making this video with clear explanations. I used to work in lcd panel factory in Taiwan as a HR, but the factory R&D never taught me such a useful tip, even though I may not be able to open the cover, test the voltage, and fix it by myself. Still thanks anyway.
I've fixed 4 different models of LCD tv's with one simple solution. Remove the back cover of the tv, take a good can of compressed air, and blow out as much of the dust as possible. Make sure to concentrate around all the capacitors. And I'll guarantee you 80% of the time, this will fix your issue and the lines will disappear. So try this fix before contacting a repair centre, or even replacing the tv.
Thanks for this video, it worked and was quite easy to do. You saved me a new TV at over €1000! One question though, I now have a horizontal single black line that pulses on and off for a few seconds at a time. Since its only one line I can live with it, no problem, but was wondering why and if it is repairable. Thanks again
Congratulations on the repair. Not sure about the line, likely it’s part of the internal lcd issue your screen is having. You might be able to minimize it with blocking a different row signal. But if you’ve tried all of the combinations then that may be the best you can get.
Thanks for the hack! This did fix an horizontal line I had on my 4k TV. Only issue is afterwards I get some faint horizontal lines across but not very noticeable. For the tape I winged it and guessed right by trial and error and it seemed to do the trick!
If you use trial and error again, like you did in another of your videos, could you find which exact line or lines were causing the malfunction? Therefore, wouldn't less tape blockage boost the signal by chance? Thanks again for your content! I'm trying to fix horizontal lines on a TV given to me.
Finding the exact cause can be tricky because it is likely something not visible (or accessible) inside the lcd assembly. So you need to do trial and error diagnostics from the outside (ie mess with the row signals) to try to narrow it down. The row signals are individual so there isn't a boost, per se. It's a bit complicated to explain but that's what I was hoping to do in this video, lol.
+FrugalRepair Thank you for the explanation. I had seen people using tape, but they did not explain WHY. I have an electrionics degree, struggling to understand why blocking signal fixed a screen issue. You have shown the theory behind the repair. Much appreciated.
Thanks! Yes you can replace an LCD on the TV, but the issue is that it has to match what the timing control board is outputting. That is, all of the signals must match on both sides.
Yes you can, you need to check that vcc is the same, also, if the screen has an lvds cable or ribbon cable you need to check if they are the same kind, for example there are screens that are milimetrical so they have only one ribbon cable to the tcon this cable had like 50 lvds line or more, also you need to check if the screen had the same ratio, you cant replace a 60hz screen with a 120hz screen unless you have a converter, also they need to be same size, inches are not standar for every screen, you can have two 42" screens but one can be 2 or 3 milimiter bigger. Sony is compatible with samsung and lg is with any chinese screen
Thinking outside the box, love it! So a timing signal that's shorted to ground could be fixed with tape because it's pulling the whole row low. I'm guessing that's the explanation?
It’s likely the get signal that is duplicated from both sides of the lcd assembly. Blocking the side with the short allowed the other signal to work, but it’s not 100%, which is why there are duplicate signals in the first place. But if you can’t notice the difference when watching, then it probably doesn’t matter.
Thank you for making this wonderful video that plainly explain how a LCD monitor works. I enjoyed watching both parts. I repaired a few monitors in the past simply by replacing components without fully understanding how the monitor performed the signal processing part. I guessed my luck ran out when I got a panel displayed everything in BGR instead of RGB while appeared to be intact. I have been stumped for awhile trying to look for known cases with similar issues, but I think I didn't even know how to ask the right questions. It's nice to finally know what to look for!
Have a Samsung UN55NU7100FXZA Model that kept recycling on and off. The standby LED would blink twice before it recycles again. This method you describe also worked to resolve this issue...It was also the screen on this model that was causing this issue. Thanks for sharing your knowledge.
@@FrugalRepair My Vizio SmartTV has horizontal, fuzzy lines but it has a vertical roll as well. So this may not do the trick but I thought I'd try your trick with the tape (maybe need to block some of the Vertical connections as well?)..... I would take apart Halloween and Christmas decorations as a kid to get the motion sensor or lights to work again. Most of the time just taking connections apart and putting back together did the trick. And I fix cell phones here and there. But I love taking apart electronics to diagnose and fix them. I never knew how the pixels in an LCD worked, so cool to have someone explain it other than, "It's magic" (What my electronics engineering teacher told me about how radio signals work). Needless to say, I did not care for that teacher. Thanks again
Hi, I have been checking out your videos and thanks for sharing the quick diagnostic tips. I have an issue and still cannot locate the problem. My issue is the screen goes dark between 6-12 minutes with no noticeable lines on the screen and I have already tried swapping the t-con board. I went as far as outline the front screen off to check the LEDs and they function so I am starting to hit a wall and if you have any other suggestions I would love to hear them!
Sounds heat related to me. Did you try turning the brightness down to 10% and see if it lasts longer? Or even put a fan on the vents of the tv to keep it cool?
should've watched this long time ago,one of my sisters always ahve a big flat screen with lines and they always just throw them or just leave it laying around unused
First I would like to thank you for the simple and excellent explanation.I have a Panasonic Fhd tv which started showing the horizontal lines. I opened it and found the t con board which was surprisingly an lg board ,identified that the left half was the reason for the horizontal lines and the tape actually fixed it. I have a question though where actually is the problem,is it the led panel or the t con board ?
Thanks! I do have a TV that has vertical lines so maybe I will make a video sometime. Great suggestion. The jerry rig solution many times for that is to put non-conductive material on top of one of the electrical connections and force it down by screwing the frame down on it to create pressure on it.
Hey Rhys.. I have a question.. When you do a continuity test on the signal lines, cant that damage the sub pixels ? I am not sure what the average multimeter puts out for a continuity test or what voltage the sub pixels are running at so could the meter output cause secondary damage ?.
I had a power issue at my house. When I turn my Sony TV on it had double images. Then the next day it started flickering. Tried the tape and it worked. TV looks great again. Thanks
This is very interesting I always like messing around with electronics and things that are complicated to fix I have a nice Sony and I'm going to try this and I will let you know what happens thank you for sharing
this is really well explained, finally someone explain and understand what he is doing.... My question is : Is there a way to use a multimeter and measure those signals to see exactly the signals paths that are shorted to be able to block exactly those line and not others?
Thanks! You could possibly use a DMM in continuity or diode mode to diagnose it. It would depends on things like your DMM's settings and the strength of the short (resistance).
Hi Reese. Thanks for sharing such valuable insights with us! I have an issue with my LCD where I see horizontal waves. They're moving continuously from bottom to top and are particularly noticeable with dark backgrounds. Do you have an idea of what the issue might be?
Expectation: 'How to fix a dead TV with a single piece of tape' Reality: Most complicated video I've ever seen jejeje. 10/10 video, will try when I have some time to kill
Thanks so much for the video! My 7yr old (fairly expensive), 65in curved Samsung just developed a single, very thin horizontal line. It's not all that noticeable but annoying nonetheless. (Other than the line, it's fine otherwise.) Assuming I could find the right pin to block, would this method take care of it?
I have a broken 4k tv but honestly since I would barely use it even if it worked I've been looking for repair ideas cuz I don't care if I completely wreck it. Got a ohm/volt whatever meter and a soldering iron. Think it'll be cool to try fix it either way! ANYWAY. What I really wanted to say you make cool and informative vids so hi I'm a new subscriber!
@@FrugalRepair Thanks! I'll first need to figure out what's broken/also take it off the wall mount but I most definitely find the idea of a DIY fix awesome. Got no idea how the reader thingy works but that's all part of the fun. Fix it til it's actually broken is what I've come to understand from the repair community which honestly is absolutely amazing! For my model it seems the most likely cause is a bad capacitor but I first need to figure out how the reader works and how to use it to pin point the problematic part.
I've glad to know that someone explained this issue I thought the screen was built with problem defect after a few years however I still would like for you to explain how to deal with those TV that does not have t con on board and the lvds cable is connect directly to the screen with buffer board do you cut
i have a 2017 Samsung TV (UN43MU6300F) that i was about to trash before i found this video. might as well open it up and give this a shot! thanks for making this.
Brilliant 2 videos, I used the method and fixed horizontal lines and flickering image, but I have lost the red signal to half of the screen, will have to adjust size of tape now by trial and error 😕
Thank You. This actually works l picked up a free 75" LG had horizontal lines across the entire screen, it was the right ribbon at fault,l didn't want to waste time so decided to just cover the first 12 gold lines, from the left side of ribbon towards the right (didn't remove the entire ribbon so from the left side of the ribbon when looking at it still in place basically) ...l covered exactly 12...and Bang it was fixed😀...couldnt believe it. Try blocking first 12 lines on bad ribbon (from the left side) and see if that works first like it did for me😁!! Cheers

My mom bought in the 80's a Schneider that had an ITT tube, worked for 17,5 years constantly on, many people told us, it was trash, well known brands were gone sooner than our tv set.
I've bn looking for a clip like this for yrs. How I haven't stumbled across it until a couple days ago I do not know. I fixed 2 50 in. TV's with many horizontal lines and i just had put them in the shed, did not have the heart to throw out. Also, scored a 65 inch off of marketplace for free because their cat had knocked it over and it was also horizontal lines. You are a gem 🙃 thank you for this wonderful video 🙂
That's great! Glad to heat that the video has helped.
Thanks for describing the relationship between the transistor and capacitor and the vertical and horizontal exchange of data and frequency band
Dude! Thanks for the explanation!
Picked up a free Samsung smart TV and watch two videos showing to use tape but they didn't show the fault finding process, now I'm off to give it a try.
Extraordinaria forma de explicar una solución y, al mismo tiempo enseñar como funcionan las pantallas lcd. eres un buen ser humano. Muchas gracias God bless you
I waited for 2 years to find a solution for my 55EX720 3D TV double image problem, and today I managed to fix the issue, as suggested by using a tiny strip of cellophane tape. Thank You.
Congrats on the repair!
Thanks for such a great explanation I have never seen someone explain about this problem so well and organized
Glad it was helpful!
Hi am so happy to meet someone like u on UA-cam that knows so much and explain stuff well. I have some problems with electronics.
Thanks so much for making these videos! I looked around for repair insights like this back in march, but glad I kept the broken TV "just in case".
Also, your continuity test "swipe" at around 5:25 was really reassuring, as I would've worried I could short something else out by just probing those tiny traces at random. Thanks especially for that!
Thanks! I hope you can get your TV repaired.
@@FrugalRepair Hey bud, my TCL qled panel got damaged , my son threw a hanger at the screen, there was a crack and white vertical lines about 2 inches in that region, after a month of r&d the tcl person gave me a about 200$ quote, now my question is how can i figure out whether he has fit a qled panel or a UHD panel
@@ktolwal If TCL quoted a price lower than new purchase price of an entire similar TV, there must be a misunderstanding. LCD panels always cost more than a new TV especially considering shipping and installation. To answer the question, There is only one specific panel for a given TV, no substitutions.
Thanks commentor you can be frank too
Hi Sir,
I am Rao from India.
I did as you described and solved the issue of horizontal lines.
Thank you 😊.
Thank you for figuring this out. You are a great person. Blessings to you and your family.
Thank you for the encouragement!
I've watched a few videos about using the tape trick, but have always been mystified how it works. Thanks for explaining.
FINALLY the Louis Rossmann of LCD TVs!! Your last video troubleshot a TCL LCD, I just had a 43" 4k TCL flicker then the backlight seemed to fade out on the right side. I see the image across the entire screen however it gradually gets darker the further to the right. Any troubleshooting suggestions or can you perhaps create a video on how to repair / troubleshoot backlighting on LCD panel? Big thanks, thumbs up and sharing your channel.
I feel honored being compared to Louis Rossman. Thanks for the comment and share! Did you get my pdf? I have a led backlight suggestion in there. Sounds like you need to replace some of the LED modules. I’ll create a video sometime, I’ve got a pile of free TV’s people have given me.
@@FrugalRepair Joined the email list but have not received the pdf.
Let me know if you haven’t received it. It takes a few minutes to send out after someone subscribes.
@@FrugalRepair I received the link, thank you! I've tried dimming the brightness as suggested but the dimmed side is dropping in brightness as well. I would expect the bright side to match the dark side when decreasing the brightness at some point IF a backlight LED was out. When the startup screen appears after a hard restart the entire screen is PERFECT for 2 seconds, then the dimmed area appears. Possible power/short issue I wonder? Any suggestions would be awesome, thank you.
Good to hear you got the link. What you are describing sounds like there is at least one shorted LED module on the darker side. The reason you get full brightness at boot up is that the power supply ramps up the voltage all the way and then the short circuit happens to take it out some others LEDs (maybe it's localized to one of the LED strips).
Omg it worked i cant thank you enough i really wanted to buy a tv for my room but i spent my money on a pc i recently got a free lg 32" tv from adverts i spent 2 days troubleshooting and now it works you really inspire you i cant thankyou enough for your info i want to do electrical engineering or repair when im older and i have leared so much from your video keep up the incredible work
I’m so glad to hear you fixed the picture on the tv. Congratulations!
Amazing video man! I really appreciate the time and effort you put into this. I spent way too many hours on this when you summed it up in mins. Other videos wouldn't go down to the details that you did, leaving for an incomplete understanding. Thank you.
Thanks for watching! Glad you enjoyed it.
WORKED!!! Thank you so much. I had a 58 inch Hitachi tv that had a suspected bad tcon board. Then my kitchen JVC Fire Tv panel board packed up. Not worth fixing the JVC but I used the Tcon out of the JVC as it was the same part number and make but version 4 rather than version 1 that was already in the Hitachi. Then it all loaded up (it had been dead in the garage for two years!) but it had the horizontal lines. Took off each cable and figured it was the right side. First attempt of tape in the middle didn’t work but moved it right a bit and second try worked! It’s not 100% but it’s 99.99%! Now I have a very happy wife as she can watch Strictly in the kitchen. Happy Wife…Happy Life!🤟👍👊
Awesome, congratulations!
This actually worked for me! Thank you!
I had a single pixel-length black horizontal line a third way down from the top of my Samsung TV, that faded as it went from left to right. After placing a mm of electrical tape on the 15th trace on the ribbon connected to the TCON board, it got rid of it. The only complication like you mentioned at 7:20, I have faint lines from top to bottom accross my TV, but they're barely noticeable unless I am standing 3 feet or closer.
Congrats! That's great.
Hey Cam. How did you narrow it down to the 15th trace?
@@therealeffingdeal A lot of trial and error. I just kept blocking 2 traces at a time until I noticed a difference on the screen.
@@camokid95 im working on a QLED with a single line across the screen. I don't want to block off half a dozen tracks and loose picture quality since I reason that is likely a single trace that's the issue.
How does your picture look with your fix? Do you see any diminished picture quality in the trouble area?
@@therealeffingdeal It appears diminished, but not that noticeable from a distance. You should only block the trace relevant to the line that's a showing the dead pixels.
just used this method on an Insignia 50" 4k tv with horizontal line across it and it worked...I just took a small piece of tape and just moved it around and i found the spot....Thanks
So great to hear!
Man !!!
You are legend !
Ive been banging my head with lvd ribbon cable, even swapped tcon board but couldn't figure out whats going on.
Your explanation answered my question..and ur method worked 100%.
For me (Samsung 50" smart) it was the last set of 7 lines in right ribbon cable (if looking from rear of TV)
I did like 20-25 hit and trials of 7 lines wide tape and finally hit the exact set of lines !
Thank you so much brother, you earned some prayers from me :)
That’s so great to hear! Thanks for sharing and congratulations.
Thank you soooo much!!!!!! Tried this on my second attempt and boom two faint horizontal lines gone subscribed!
Awesome, congrats! Thanks for the sub!
Looking forward to trying this with my Samsung 65”. Thanks for all your knowledge. Stay safe.
Hope it works! Let me know how it goes.
Thank you so much...my husband tried this and it works very well now.Thank you from Trinidad
🇹🇹🇹🇹🇹🇹🇹🇹👍👍👍🙌🙌👏👏
Wonderful!
Well done. Your intense and thorough studies paid off. I looked at so many fake rubbish videos I almost gave up. Thanks for the real answer.
Thank you for your kind words.
I can’t thank you enough! So awesome! Found the rows, cut the tape and the tv works perfect!
Awesome! Congratulations and thanks for coming back to let us all know.
hi. which area need to put a tape
Thanks for the explanation. I “fixed” mine a number of years ago and couldn’t understand why it worked.
You used the blocking method on the row signals?
Thank you very much for this video. My LG 42UB820V developed the same fault as described in your video. I located which side was causing the issue and identified the clock pins (there was 8 from pin 3 to pin 10 on the ribbon). Small piece of sticky tape over the 8 pins and all back to normal. What an incredible fix, sheer genius!!
Hey, how did you locate the faulty pins?
How to know the clock pins?
Bro, this basically fixed our TV. We taped over the left-most 4 pins on the left side ribbon (looking at the back of the TV, oriented right side up). The only down side is that it seems the red LEDs are affected by this. There are horizontal wavy patterns every time a lot of red is shown on the screen (like in Netflix, for example).
Either way, our TV literally randomly started showing lines and color stains, and this helped us completely get rid of those, so our TV is watchable once again. Thank you so much, dude!!!
Congrats, thanks for letting us know!
@@FrugalRepair It's so appreciated. We noticed when watching shows now that the right side of the screen is really missing a lot of red in the color. It's like when character move from left to right, they get dreary and depressed as they lose their vibrancy haha. Might do the same thing with the other side of the screen so that there's at least no difference.
Do you know why this would happen?
Awesome, i just discovered your channel yesterday and now I'm wondering what do you do with all of these repaired TV's?
I hope you’ve enjoyed the videos! Haha, I have lots of TVs. But some are friends that I fix for them, some I might give away, some we keep, some I might sell.
Today, after watching your video, we fixed 3 TVs that TLC said were out of warranty. Thank you.
That's awesome! Thanks for letting me know.
Thank you for making this video with clear explanations. I used to work in lcd panel factory in Taiwan as a HR, but the factory R&D never taught me such a useful tip, even though I may not be able to open the cover, test the voltage, and fix it by myself. Still thanks anyway.
Glad it was helpful!
Another one fixed!!!!! thanks to your video... i had ordered a t-con and all i needed was some scotch tape.
You are such a nice guy for sharing your knowledge.
Thanks a million from Perth Western Australia!
Thanks! I want to help as many as I can to be inspired to tackle projects themselves and repair things rather than throw them away.
Just tested this on my Hisense TV which had double lines on it and YES! it worked after about 3 trials. Screen all clear
Congratulations!
This is awesome! What if you wanted to actually fix the problem though? Is this issue caused by a bad resistor, cap or chip?
Could try opening the TV & replacing the T board & screen tape but it's probably cheaper & easier to get another TV
Been looking for a fix for my tv for a while. Was about to give up and replace it. Good as new now. Thanks a lot!
Congratulations! That’s great to hear.
I've fixed 4 different models of LCD tv's with one simple solution. Remove the back cover of the tv, take a good can of compressed air, and blow out as much of the dust as possible.
Make sure to concentrate around all the capacitors. And I'll guarantee you 80% of the time, this will fix your issue and the lines will disappear.
So try this fix before contacting a repair centre, or even replacing the tv.
Thanks
80% of the time it works every time. lol
You saved tons plastic + e-waste, some smart guys definitely be using this trick.
Thanks for this video, it worked and was quite easy to do. You saved me a new TV at over €1000! One question though, I now have a horizontal single black line that pulses on and off for a few seconds at a time. Since its only one line I can live with it, no problem, but was wondering why and if it is repairable. Thanks again
Congratulations on the repair. Not sure about the line, likely it’s part of the internal lcd issue your screen is having. You might be able to minimize it with blocking a different row signal. But if you’ve tried all of the combinations then that may be the best you can get.
Thank you very much for sharing the engineering behind the TV signal. This is really very good. I learn so much from such a short video. Awesome!
Thanks for watching!
Thanks for the hack! This did fix an horizontal line I had on my 4k TV. Only issue is afterwards I get some faint horizontal lines across but not very noticeable.
For the tape I winged it and guessed right by trial and error and it seemed to do the trick!
Awesome! Congrats.
If you use trial and error again, like you did in another of your videos, could you find which exact line or lines were causing the malfunction? Therefore, wouldn't less tape blockage boost the signal by chance? Thanks again for your content! I'm trying to fix horizontal lines on a TV given to me.
Finding the exact cause can be tricky because it is likely something not visible (or accessible) inside the lcd assembly. So you need to do trial and error diagnostics from the outside (ie mess with the row signals) to try to narrow it down. The row signals are individual so there isn't a boost, per se. It's a bit complicated to explain but that's what I was hoping to do in this video, lol.
Just come across your video, it has saved me. My tv was exactly this and a little bit of tape sorted it out. Thanks bud 👍
Awesome! Congratulations on the repair.
+FrugalRepair Thank you for the explanation. I had seen people using tape, but they did not explain WHY. I have an electrionics degree, struggling to understand why blocking signal fixed a screen issue. You have shown the theory behind the repair. Much appreciated.
Thanks for watching!
thanks dude you explain so well i fully understand i have scanlines pulsating from bottom to about 1/2
Took me a while to decipher the signals but managed to figure it out. Really good video 👍
Congratulations! That’s great to hear.
Brilliant video. Perfect way to get technology translated into a understandable &
simple way. Excellent indeed !!
Thank you for your kind words!
Thanks for the insight, I managed to repair my LG TV, that I was just about to throw away, with just a little piece of tape! Awesome!!
Congrats!
haven't done this yet but man this really help me understand how monitor and to troubleshoot this problems.
The man the myth the legend 🚫🧢
Not quite, but hope you enjoyed it!
Reese!! You are awesome!! Quick, lots of info and you speaka my language!! Even your intro is short and to the point!! Thanks
😀
Thanks for watching!
You're a legend! thanks for sharing your knowledge. Question: can you change a broken LCD panel from a different brand or model? Is that possible?
Thanks! Yes you can replace an LCD on the TV, but the issue is that it has to match what the timing control board is outputting. That is, all of the signals must match on both sides.
Yes you can, you need to check that vcc is the same, also, if the screen has an lvds cable or ribbon cable you need to check if they are the same kind, for example there are screens that are milimetrical so they have only one ribbon cable to the tcon this cable had like 50 lvds line or more, also you need to check if the screen had the same ratio, you cant replace a 60hz screen with a 120hz screen unless you have a converter, also they need to be same size, inches are not standar for every screen, you can have two 42" screens but one can be 2 or 3 milimiter bigger. Sony is compatible with samsung and lg is with any chinese screen
Thinking outside the box, love it! So a timing signal that's shorted to ground could be fixed with tape because it's pulling the whole row low. I'm guessing that's the explanation?
It’s likely the get signal that is duplicated from both sides of the lcd assembly. Blocking the side with the short allowed the other signal to work, but it’s not 100%, which is why there are duplicate signals in the first place. But if you can’t notice the difference when watching, then it probably doesn’t matter.
I'm just came here to fix a dead pixel, AND now i want to build a Tv by myself
Fascinating! So well explained, I loved it and explained it to my wife after I'd fixed our TV with tape. Thsnk you!
Thanks for watching!
Thank you for making this wonderful video that plainly explain how a LCD monitor works. I enjoyed watching both parts.
I repaired a few monitors in the past simply by replacing components without fully understanding how the monitor performed the signal processing part. I guessed my luck ran out when I got a panel displayed everything in BGR instead of RGB while appeared to be intact. I have been stumped for awhile trying to look for known cases with similar issues, but I think I didn't even know how to ask the right questions. It's nice to finally know what to look for!
Thanks!
Have a Samsung UN55NU7100FXZA Model that kept recycling on and off. The standby LED would blink twice before it recycles again. This method you describe also worked to resolve this issue...It was also the screen on this model that was causing this issue. Thanks for sharing your knowledge.
When all you wanted was to fix a tv but you come out as a tv expert
Thanks for the explanation. Hopefully this will work out and I get my screen back. Wish me luck. I will update with the outcome.
Really great information. I love technology and love fixing electronics. I will be watching more of your videos, thanks for making and sharing them!
Thanks. That’s great that you like fixing electronics! What have you been working on lately?
@@FrugalRepair My Vizio SmartTV has horizontal, fuzzy lines but it has a vertical roll as well. So this may not do the trick but I thought I'd try your trick with the tape (maybe need to block some of the Vertical connections as well?)..... I would take apart Halloween and Christmas decorations as a kid to get the motion sensor or lights to work again. Most of the time just taking connections apart and putting back together did the trick. And I fix cell phones here and there. But I love taking apart electronics to diagnose and fix them. I never knew how the pixels in an LCD worked, so cool to have someone explain it other than, "It's magic" (What my electronics engineering teacher told me about how radio signals work). Needless to say, I did not care for that teacher. Thanks again
Thank you for this video. My TV has lines and I will try to fix it on my rest day. Will comment again if I have any questions
Hi, I have been checking out your videos and thanks for sharing the quick diagnostic tips. I have an issue and still cannot locate the problem. My issue is the screen goes dark between 6-12 minutes with no noticeable lines on the screen and I have already tried swapping the t-con board. I went as far as outline the front screen off to check the LEDs and they function so I am starting to hit a wall and if you have any other suggestions I would love to hear them!
Sounds heat related to me. Did you try turning the brightness down to 10% and see if it lasts longer? Or even put a fan on the vents of the tv to keep it cool?
@@FrugalRepair I have not but this will be the next attempt, ty for the reply!
The most logical explanation on why does tape "fix" TCom board problem! :)
The problem is actually on the LCD in most cases, not on the tcon.
@@FrugalRepair Thanks!!
should've watched this long time ago,one of my sisters always ahve a big flat screen with lines and they always just throw them or just leave it laying around unused
First I would like to thank you for the simple and excellent explanation.I have a Panasonic Fhd tv which started showing the horizontal lines. I opened it and found the t con board which was surprisingly an lg board ,identified that the left half was the reason for the horizontal lines and the tape actually fixed it.
I have a question though where actually is the problem,is it the led panel or the t con board ?
I definitely just started covering and uncovering lines on the board until i got a good picture and it worked lol 😂 thanks ! Merry Christmas!
Congratulations! Merry Christmas to you.
Thank you very much for showing us the easiest way of repairing tv. God bless you.
Good job!Looking forward to a video, where you talk also about vertical lines issues and possible fixes.
Thanks! I do have a TV that has vertical lines so maybe I will make a video sometime. Great suggestion. The jerry rig solution many times for that is to put non-conductive material on top of one of the electrical connections and force it down by screwing the frame down on it to create pressure on it.
@@FrugalRepair i have a vertical lines can you please make a video??
Thank you sir i learnd a lot I want to continue studying Electronics but Im 42 years old this help me a lot thank you sir...
Thanks for watching!
Hey Rhys.. I have a question.. When you do a continuity test on the signal lines, cant that damage the sub pixels ? I am not sure what the average multimeter puts out for a continuity test or what voltage the sub pixels are running at so could the meter output cause secondary damage ?.
I had a power issue at my house. When I turn my Sony TV on it had double images. Then the next day it started flickering. Tried the tape and it worked. TV looks great again. Thanks
Congratulations on the repair!
Did you open the tv??? Mine is 65” and on the wall and I couldn’t watch this full video he’s doing too much of explanation
Your kung Foo is strong 💪. My respect gladly 💯.
Thanks!
This is very interesting I always like messing around with electronics and things that are complicated to fix I have a nice Sony and I'm going to try this and I will let you know what happens thank you for sharing
I hope it goes well!
u a genius broooooooo
this is really well explained, finally someone explain and understand what he is doing.... My question is : Is there a way to use a multimeter and measure those signals to see exactly the signals paths that are shorted to be able to block exactly those line and not others?
Thanks! You could possibly use a DMM in continuity or diode mode to diagnose it. It would depends on things like your DMM's settings and the strength of the short (resistance).
Hi Reese. Thanks for sharing such valuable insights with us! I have an issue with my LCD where I see horizontal waves. They're moving continuously from bottom to top and are particularly noticeable with dark backgrounds. Do you have an idea of what the issue might be?
I’d try the diagnosis in these videos. You’d want to isolate if the issue is in the lcd panel or on the tcon
Thank you so much!! You saved me a tv! And I learnt something new today. Thanks for your time and effort! ❤🎉
Glad to hear it was helpful!
Expectation: 'How to fix a dead TV with a single piece of tape'
Reality: Most complicated video I've ever seen
jejeje. 10/10 video, will try when I have some time to kill
LOL, thanks!
I should have watch this video years ago. Thank you very much for this very informative video. excellent!!!
Glad it was helpful!
My lines are horizontal and they happened randomly I’m so scared
same thing happened to me what did you do ??
Thanks so much for the video! My 7yr old (fairly expensive), 65in curved Samsung just developed a single, very thin horizontal line. It's not all that noticeable but annoying nonetheless. (Other than the line, it's fine otherwise.) Assuming I could find the right pin to block, would this method take care of it?
I have a broken 4k tv but honestly since I would barely use it even if it worked I've been looking for repair ideas cuz I don't care if I completely wreck it. Got a ohm/volt whatever meter and a soldering iron. Think it'll be cool to try fix it either way!
ANYWAY. What I really wanted to say you make cool and informative vids so hi I'm a new subscriber!
Thanks! I hope you can fix it!
@@FrugalRepair Thanks! I'll first need to figure out what's broken/also take it off the wall mount but I most definitely find the idea of a DIY fix awesome. Got no idea how the reader thingy works but that's all part of the fun. Fix it til it's actually broken is what I've come to understand from the repair community which honestly is absolutely amazing!
For my model it seems the most likely cause is a bad capacitor but I first need to figure out how the reader works and how to use it to pin point the problematic part.
If you haven’t already, it might be helpful to download my PDF, I have some diagnostic steps in there.
I've glad to know that someone explained this issue I thought the screen was built with problem defect after a few years however I still would like for you to explain how to deal with those TV that does not have t con on board and the lvds cable is connect directly to the screen with buffer board do you cut
i have a 2017 Samsung TV (UN43MU6300F) that i was about to trash before i found this video. might as well open it up and give this a shot! thanks for making this.
Brilliant 2 videos, I used the method and fixed horizontal lines and flickering image, but I have lost the red signal to half of the screen, will have to adjust size of tape now by trial and error 😕
Thanks! Hope you can figure it out.
Thank You. This actually works l picked up a free 75" LG had horizontal lines across the entire screen, it was the right ribbon at fault,l didn't want to waste time so decided to just cover the first 12 gold lines, from the left side of ribbon towards the right (didn't remove the entire ribbon so from the left side of the ribbon when looking at it still in place basically)
...l covered exactly 12...and Bang it was fixed😀...couldnt believe it.
Try blocking first 12 lines on bad ribbon
(from the left side) and see if that works first like it did for me😁!! Cheers
Wow, congratulations!
