What was the best thing someone gave you because they didn't want it any more ? It could be broken or working. If broken, what did you do to fix it?

I am a 67 year old woman who has always loved (since my childhood) to repair appliances. I had a 55" TV that was not working after only 3 years. I discovered this video and started to repair it. My TV is working great after a few hours to find the tiny little part to put the tape in. Thanks for sharing your genius!

at last someone who actually explains whats going on. from one old tv engineer to another .respect

Thanks Rees, I fixed our TV today, with a tiny piece of sellotape. I didn't have a clue where the clock wires were, but I tried each wire one by one, and within 10 minutes I had isolated the shorting issue. The TV looks greatnow, thanks so much! I'm so happy and I learned so much about monitors from your videos and taking the monitor apart, priceless!

I been fixing TVs for a while and this was one of, if not the easiest fixes ever. Thanks a million. You definitely learned a subscriber.

I must say man, after 5 years of DIY TV fixing this might be the single most useful tip in diagnosing picture problems. I have never ever heard of anyone talking about clock lines in any video, literature or otherwise and 've done a lot of research and reading on TV repair. You got my vote, subscription and like. Keep up the great work!

This method revived my 3-year-old Skyworth TV. Two technicians said that it was beyond repair. Saw your video and proceeded to place the tape on the ribbon. After about 30+ tries, the 2mm tape saved my TV. Thank you from Malaysia!

This guy really has a passion for what he does. He doesn't just look at the major parts for issues, he dissects the parts until he finds the issue that is creating the problem. That is a rare find in, any field of prepare work. Great job guy...,!!👍🙂

Great video!! I love that you not only fixed it, but you explained every part of it along the way. It’s nice to know what you’re doing, not that you just put tape on it to fix it. 👏

My son and I fixed his Sony TV today with your trick. We both were surprised that it worked in the end. We had a bit trouble finding the Clock lines because they were labelled on one connector but not on the other. Finally we managed it and are very satisfied. Of course you can still see some lines but only if you are near to the TV.

Well,,,,that was amazing how you went through those lines and found the problem, you make it seem so simple and easy. Thanks EJ

I had to come back to this video for a reason.. my Panasonic led tv had same flickering issue they sent a technician from Panasonic but he couldn't repair it and said ill have to go for screen replacement which was costing me price of a new tv...also he told me that this tv has absolutely no value now if I give it in exchange for new tv.. I denied screen replacement and started searching on yt for solution and came across this video. I'm glad to say I've fixed the tv myself just by watching this video..their technician failed to do this simple fix. Thank you for making this video you saved my $$

Just found you today. They gave me yesterday a 75" qled Samsung smart TV. Haven't repaired yet. Cause I'm also a handyman/concrete/carpenter. On my way to and from my jobs I pick up fridges, water coolers, dryers and etc. Either I fix or remove parts. Already have a year doing this. After watching you the tv has no chance. I'll lyk when I get it running. Or for some advice. I'm bartering electrical work on his home for the TV. But he didn't commit me to it. The tv is new. Lamp hit it. Also he introduced me to my favorite fishing spot. That I happen to be the master of now. Since 1995. Thanks for your video.

I garbage picked a Toshiba 50” 4K with built in Firestick manufactured in 2018. I followed your video because the entire screen had horizontal lines. One side was good. I used the scotch tape on the other side slowly removing tiny strips with a exacto blade until I had a beautiful picture. The tv works fantastic now. Thank you for your help.

One of those so simple I can't believe it works things. Spent an hour with a multimeter trying to find a short and failed. 5 minutes cutting tape and sorted. Thanks a lot, very intuitive solution.

You did such a good job explaining exactly how you were doing everything then I'm 100% confident I could fix this problem myself

That was amazing. I have been fixing LCD TV's since 2010 and never have I ever been led to this repair method. Of course I am doing warranty repair so if the T-comm board is replaced and I still have the same symptoms whatever company just replaces the TV. However I just got for free a nice 70 inch Vizio that has back light and when the menu buttons are pushed there is a faint raise in luminosity on the screen where the menu would normally be but no text or pictures otherwise. The luminosity gain follows when I scroll through the menu blindly so I know the TV works - just going to be and issue with the T-comm board - but thanks to you if I pull out that one cable at a time and find it is not the T-comm board but something in the panel I will not have to take the time to part this beast out - I should be able to work through the clock connections and could be a quick fix almost free - thank you!

Finally, someone that speaks English explains with detail, what causes TV LCD panel issues. Louis Rossman would be so proud of you. Thank you and God bless you Sir!!!!

I was finally able to use your method for a Sony XBR-65C900C. Following your suggestions, I was able to block the ribbon lines causing the issues with tape and now all issues of the 4K TV are resolved. No more black lines on top of the screen and no more out of focus intermittent problems. It is just like new. I did some try and error and ended up blocking around 5 lines on the right side ribbon. When I saw that all symptoms disappeared, I did not try to unblock any more lines. Thanks again, you are a lifesaver.

My boyfriend just did this to my 58” Vizio, and it worked. Thank you!

Thank you 🙏🏾 so much for posting this repair video. This fix worked on my Samsung UN55KS8000FXZA that kept boot cycling. You saved me a lot of $, and I feel so accomplished. I did this initially and it did not work. I knew I had a good power supply, but was not sure about the main board and led panel. I went ahead and installed a new main board and no change. I did not find any burned resistors on the led panel. Went back to scotch taping along the 2 connectors on the main board. Tried a few different sections and then all of a sudden, voila! For anyone out there with a Samsung and who has tried almost everything, try the scotch tape method again on various sections. You may get lucky! It’s worth a shot and costs zero dollars!

I love how much clear info you gave in 10 minutes...this same amount of info in other videos takes 55 minutes with intros and people trying to display all aspects of their personality...and by the time you're done watching...you're exhausted and you decide to just buy a new TV and be done with it.

Thank you, thank you, thank you Mr. FeugalRepair Man! You just saved me from having to buy a new TV! Even though I had to cover up a number of pins instead of 1 (not nearly as skilled with an exacto knife as you are) I don’t notice any difference in image quality. I am telling everyone I talk to that they MUST subscribe to your channel! I cannot thank you enough for all the work you put into your videos and teaching us how to repair instead of replace. You are incredible!

That was an interesting diagnosis. I've never seen this kind of process of elimination to fix horizontal lines on a large lcd screen. I'll probably never see this problem in real life again. It seems like a rarity but it's nice to know how creative one can be in finding a creative solution to pretty much bypass the issue. Nice job FrugalRepair.👍

I am happy to inform you that I followed your steps and was able to stick the tape to get the picture back. The issue of fine lines was still there but I did not have your patience to find which was the faulty line to cover it with tape. The way you took out time to showcase the issue and resolution is commendable. I had 3 engineers who told me that the TV's screen was gone and it would be replaced by paying 50% of the TV cost, a small piece of tape did what these engineers could not do.

never seen anyone explaining something with so many details. you are an amazing person thank you so much for your help.

So glad I found your page! The material you cover is so interesting and I love the way you go about diagnosing and determining the issues. My dad used to repair TVs back in the 70s and he would include me and ask me to hand him a tool or something and I have good memories of that as a little girl! He would also use a mirror in front of the TVs so he would not have to keep flipping the screen around, which I thought was a really cool idea! Thanks again for the great info!

Just fixed my TV following your advise. Tape??? You sir are a wizard. Thank you!!!

Thank you very much for this informative and precise education. I nearly gave out a huge amount of money for a replacement of my 55" WebOS LG Tv screen. I got it fixed following the information and guide. Thank you very much and God bless you.

Dude you are amazing. I have never seen anything like it.....I have learnt so much from this video. What an eye-opener.

Great instructional video. Excellent and Intelligent troubleshooting skills. One of the best I've seen on youtube. The prior tech; as most people, have no such wisdom to isolate the problem to the suspect board onto the component level. They swap boards to no avail. then discard the entire system into our landfills creating a toxic disaster. Nobody takes their time to analyze the problem, research online of known defects, recalls and/or engineering flaws let alone a circuit roadmap or schematic for your specific brand and model We are a throwaway society as we would rather replace than repair. Pay for things twice out of convenience rather than DIY. The steps in this video are priceless: cause and effect, isolation, disengage, test one side by elimination, abnormal heat dissipation by thermal imaging, etc....just brilliant. I can relate with the author of repairing things that are practically new. I'm more into the "old school" vintage electronic goods of yesteryear unlike the throwaway electronics we have today. You buy a new TV. It goes out in less than a year. Its absurd as a consumer but great for our economy. Back when America meant quality, those golden years are long gone !! . . ,

After 2 hours of work with this perfect video a fix my horizontal line problem on a lg led tv. You teach one more thing to an engineer. Thanks a lot.

Excellent information and knowledge. You were able to help me restore a 55 inch Vizio that I thought for sure was a goner. It had an array of red, pink and black vertical lines covering the whole screen. I was worried both panels might be out. But following your detailed steps, I was successfully able to diagnose the faulty clock line and block it. Thank you! Money saved and felt good being able to fix it and also learn something new.

This is fantastic, exactly how DIY KZfaq repairs should be, easy to understand and undertake. Thank you for sharing

I've recently subscribed to your channel and really enjoy your content. You are very good at giving education on how to fix different projects without spending a lot of money.

Your advice saved my TV! 13 month old 55" TCL Roku went black on Christmas Eve of all days, 28 days out of warranty. I tried all the resets to no avail and was looking at replacements. Then I followed the isolation procedure outlined and found by disconnecting the right cable half the screen came back. While the clock lines wern't identified with anything like "clk", I isolated lines 2 - 9 on the left side and one by one exposed the connections. When I exposed the connection on pin 4 the full screen came back. Pin 4 was the only one I had to leave tape on and the TV is saved! I can't find any visible issues with the picture or performance. Thanks so much!

Wow, I learnt so much in so little time. Thanks allot. I used to say it next to impossible to be fixed when the screens get like that but now I have a different perspective. Thanks man.🤜🏾🤛🏾💯💯💯💯

Cool repair, Rhys! Can’t wait for the next part!

Thank you so much! My TV was a bit different, so I had to do a little bit of trial and error for how many pins in the tape went, but it eventually worked and saved me a lot of money that I absolutely did not want to spend!

I can't believe it, but this worked. We changed out the main board and T con board due to sudden vertical lines that appeared on the screen, but nothing worked. When I followed the instructions on this video, the TV suddenly started working. Thanks Frugal Repair!

Brilliant. Just found you via the solar panels. Quality, like how you point out what is on the circuit boards BC I have no idea

You, Sir, are a freaking legend. A friend of mine wanted to get rid of his 55inch Samsung-TV and gave it to me. I just taped it and it's working like a charm, even without any lines or loss of color etc.

This was the best idea I ever got on fixing a TV. I was able to fix a Samsung 70 inch my mom gave me before she threw it away. Thank you so much!!

Here dropping by like many folks to say YES THIS WORKS. Found a 50in 4k UHD Vizio on the street for free today, waiting to be tossed out. The owner claimed it "didn't work". Had some flickering issues. Took me but 45min to open the back up, test tape on the ribbon for a bit, and bingo. Like brand new. Thank you sir!

It was great bro! Nice demo! Watchiing here from phillipines! God bless!

I wish I would have seen this video a year ago when my 70" samsung did this. I knew I could fix it but couldn't find any info. I came across another video of a guy doing this and tried it. I tried it an it worked although I didnt have much info on narrowing it down or any details like you shared. I appreciate the info and need to take the tv back down and do further diagnosis now that I have the info you shared.

Thank you for this tip! After some trial and error, I found the corrct pins on the ribon cables chaining the 3 seprate lcd PCBs together. Saved my 65" TCL from the recycle bin.

Thank you for doing this and for a great detailed video on these kinds of issues. My TV (Vizio m502-b1) seems to do similarly to the darkening screen, only the vertical lines appear all in the middle, and by the bottom left corner (where the TV power button is), it seems brighter in that corner. I actually tested the ribbons and it seems like it's one of the ribbons causing the problem, so I tried taping (though I don't have a way to test which prongs nor have an exacto to trim precisely). It helped a bit but still has some glitches (much better now though than it was). Do you think that this is due to a bad T-Con board, or bad pins on the ribbon? I guess my question is, would you replace the T-Con board, the seemingly bad ribbon, or the other chip where the ribbon connects to the panel?

many thanks i fixed my LG TV today with your great help , thank you so much

Great video i love watching people that explain everything and understand it all im so happy that u have a part 2 that goes more in depth cause i love that stuff heading to it rn thank you very much keep up the great videos !

I will definitely try your tricks repair in our tv when i go back to philippines. Our tv had the same problems. Thanks in advance..new subscribers here from bahrain 🇧🇭

Man I just fixed my tv following what you did the shit really worked.. I was about to send it with the trash truck. Thanks saved me a lot of money..

Thank you sir! I love learning from you.

🎉Hi, Keshi from Nigeria, just fixed my scanfrost 55in tv after watching your video. You are the best. Thanks

Frequently in my city we have facebook curb alerts. it’s pretty common for neighbors to put free items at the end of their driveways. I was running errands and I saw this LG 4K 75 inch TV at the end of my neighbors driveway, It was free.I saw that the LCD wasn’t cracked, immediately knew that whatever was wrong with it had to be small. Took it home, watched this video. Understood everything that was said. Followed these exact steps and I now have a working TV. Your information is extremely helpful, didn’t need to take it to a technician, I became the technician. Thank you so much!!!

I've learned a lot from this video. Thank you sir!

That is one to bypass the panel issue. Good Job!

Awesome! I have been trying to figure out what's wrong with my Samsung after 1 year of use. That black cloud is what's happening and now I will try to repair it. Thank you!!!

Thank you so much for being so dedicated and kindly giving us your wisdom

Excellent work and explanation, hopefully you are inspiring individuals to TRY and fix electronics/ merchandise instead of adding perfectly good and fixable products to landfills. Thank you very much.

You are a genius!! WOW awesome job

Wow! Among the chaotic plethora of DIY television repair videos, there is a diamond in the rough. A simple 👍 is a tragically oversimplified accolade for the numerous things done right in this how to video. From the omission of unnecessary prologues or title intros created on a win 98 video editor to the excellent walkthrough narration (that clearly reveals strong ethos and logos without completely losing the novice in a sea of jargon), this video is a welcomed reprieve. Although my TV was suffering from different symptoms than the one in this example, I was captivated by the level of professionalism on display. This is a shining example of what a DIY KZfaq video should look like. It is a benchmark. Furthermore, it should also appear under the category for "How To Make Your Own DIY KZfaq Vid." Did I mention that I gave it a 👍?

Incredible! Fixed my TCL 75” 6 series. My issue was on the other side of the panel so it was a bit tricky tracing the clock lines to the other side. And definitely need at least 4x magnification! Thanks a ton!

Whaoooooooooh amazing. Didn't know that. Learn it today. May I know how these knowledge come to your mind. Or how you figured out these tricks. Thanks for sharing. 😊

wow...thank you very much for this hack. i was about to give my 55 inch Iffalcon smart tv as scrap. i did just liek you and put tape on specific lines like yours...even though the picture is not sharp and has soem lines still it works well. thanks again...

TLDR: This video helped me fix a tv I had given up on. Thank you very much for posting this solution. I don't normally comment on videos but I feel like I have to. I had recently purchased a replacement tv to upgrade to a bigger size. The tv I was replacing was fine at the time and I was going to use it in a different room. By the time I had the mount all set for the older tv (about a week) it was no longer working. It had the same issue you were having in this video... black screen with sound and backlight. I had watched a dozen or so videos on repairs and even called customer support with nothing working. So I set aside the tv because I was going to get rid of it (on a free stuff site or trashing it) but I really didnt want to waste the once perfectly good tv. Two or so weeks later I had finally decided the tv needed to go and then this video popped up on my suggested videos. I watched it thinking it would be the same as the others I had seen but the tape was intriguing. In this video you showed me something I hadnt tried (taking the ribbon cables out and reconnecting them) and I figured it was worth trying one more thing before completely giving up on it. Less than an hour later my old tv was back in perfect working order. Thankfully I didnt have to use the tape at all (those connections are incredibly small). The act of taking the ribbon cables out and reconnecting them was all it took to bring it back from the dead. The tv is now mounted and working great. Long story short this video showed me how to fix my tv and keep it from a landfill and for that I am very grateful. Thank you so much for posting this solution.

Thanks, I just followed your video and solve my tv issue!!, still working on the horizontal lines and I hope will find the short-circuit else live with that, thanks a lot and keep up your good work man.

I have a 75” TCL that had this same problem. It has two 60 pin connectors so it took a little trial and error but I was able to fix the TV and save buying another one! Thanks for posting! Worked perfectly. I wish I had a pair of magnification glasses to assist in repair but I was able to muddle though. Thanks!

wow, thanks for the sharing.

Wow, that was an amazing diagnosis Dr! Thanks for sharing! I enjoy watching people like you solve problems! My LG tv has a dark shadow on the left side of the TV! Lemme know if you have any possible solutions! Thanks a million! It’s easy to tell that you really enjoy what you do! Thanks again, Your friend, Barry

I have a VIZIO v585-j01 and it took watching this and the next video, and a little bit of guesswork, but THIS WORKED. Thank you so much for posting this!! The screen on my unit was flickering with purple and green lines and generally going haywire, and I was worried because I have no experience with electronics, but I used the method of unclipping the wiring tape on each side of the tcon board to see which side had the problem, and following through with a small little piece of tape on the wiring tape on that side and it worked!! You do need good up-close vision, or an aid for that lol Definitely made me feel myself getting older, starting at all of that miniscule circuitry 😅

That was a surprisingly awesome process, bud. In stead of thinking outside the box you just taped it up! Kickass never considered that technique. Subbing and studying the wys of your force.

Where have you been man? We miss your great content!

Pretty cool. I wish I had found your channel before I threw out a TV a year back. It kept popping a chip on the TCom boards I put in. I suspect one of your videos would have helped me find the culprit... alas, I gave up. Nice video explanation. Thanks.

I am soooooo happy that I found your video. You taught me how to fix my tv. I really think the tape made the color look more vibrate. Thank youuu for doing this video

That's really clever, i wish i could find a TV to attempt my luck. Here's hoping to more of these videos in the future

Simply excellent!

I have a 50” Insignia Roku TV. After 4.5 years, a black horizontal line emerged. I found this video and was skeptical I would be able to do it or that it would work for me. After some trial and error covering and uncovering parts of the ribbon cable, it works! Thank you for your help!

You my man just made a new subscriber. Really like the end where it shows rows. Knowledge is bliss and to my grave ill take this. Thx!

I have nothing to say.sir nice interpretation.god bless..

Successfully fixed my 55''sony led TV flickering problem Thank you sir. I am from Kerala, india

You are one smart guy! Makes me wish I was still in the trade and learning more!

Woahw. I am stunned! I have a hisense 4k TV myself, who seems Lose Power after starting it, never showing an image, only letting glow the company power led on the bottom. I will definetly watch more of your videos and do my best to fix it!

Thanks man!!! Fixed it, yesssss!

Blessings,,thank you I will have to try that one

That was wonderfully instructional. Thank you for posting it.

yes I followed your advice after replacing the main board on a vizio E420-AO to no avail and now the picture is fine. Thanks so much for the great tutorial and explanation in part 2

That's so interesting! I'm always learning stuff related to electronics and you are one of my new founds! Thank you!

Thank you very much for sharing your in knowledge. I used this to “repair” a 60” Sharp TV. I had already replaced the power board and thought it was the light strips. I prices replacement by a pro at $350, so I went to KZfaq to see how to it myself. There I found your video. Long story short, there was no jumper map so I just went to town. Saw varying results. After 4 hours, I was wrapping up for the night and took all the tape off. Somehow, everything works perfectly. No tape! Went from a dead screen with sound to tv that seems brand new. Any idea why or how that could be? Thank you again.

Holy cow this totally just worked on my Visio M50- C1!! I wasn't as precise, just put a small piece of tape on the side showing a blank screen, and had to move it around a cpl times before it worked. But I'm back to a perfect picture now. Thank you so much for posting!! Saved me a lot of money.

Great detail seen many videos but this explains perfectly now I understand what to do and I am ready to fix my tv.. Thanks.

Your tape trick worked like a charm on a 75" tcl tv that I was given. I had put money into the tv before I came across your video. Would it be a problem with the t-con board if the tape worked?

I'm to the point you're showing us, but this set up is a little different.. we need people like you on call! Lol sure would help

Thanks very much, extremely helpful. My Sony Bravia KDL50W829B had this issue in case anyone else has the same model. The clock signals only seemed to be labelled on the Tcon board on one side, and I needed to fix the ribbon on the other side! The ribbon was made up of 60 pins so took a bit of trial and error, but I removed the tape on half the pins at a time to see what worked. In the end I got down to the first 9 pins being covered and it worked fine, so I left them all covered up rather than try and refine further. Thanks again!

Great video! Thank you for sharing! We have a TV with a black screen that we've been holding onto for over 4 years and now I'm going to open it up to check things out!

I'm starting to get horizontal lines which are flickering across the top and bottom of my screen 😔 hope I can gather the courage to open it up and check it based on your advice 🙏

Thanks for all these tips! I'm facing an similar issue. My lcd monitor has some horizontal lines (on top the windows taskbar) that appear with a periodicity of about 6s (3s with lines, 3s without) . Do you think you can give me an extra tip before I unscrew everything up? I ran an autotest and the source of the problem is the monitor for sure, not from the cables or the PC.

Great explanation. Having an issue with thin color horizontal lines on my TV. I actually had this same TCL TV with the same issue. Wish I would have found this video before trashing it after trying to replace all three board in the TV....

Wanted to come back to this video and say thank you. Was able to fix the tv. Great job.

Great job 👍 where did you learn that trick from?
