This is the single coolest, most helpful tech fix I have ever seen on the web. We’ll done, sir!

THIS WORKED FOR ME ALSO. Like @johndate1776 commented above, my TCL (model 55R615) has two ribbons at the bottom of the screen near the IR sensor. Each ribbon has 80 pins. My flashing was on the left half of my screen, so I taped off pins 12 and 13 on that ribbon with simple black electrical tape. Using a reading magnifier, after about 10 cutting attempts, I got sliver of tape just the right size to cover 2 pins. I reassembled, and the flickering is gone. This video should win an award for the BEST fix-it video on KZfaq!! It is 1) very technical but easy 2) it's free 3) it SAVES the TV from going into the trash, and 4) IT WORKS! Great job. Thank you!

It worked for me. My issue was on the left side of the screen. I used masking tape and the pins where the 69th and 68th(from right to left), if you count the pins from left to right those will be the 12th and the 13th. No flickering after this!! Thanks a lot man, I'm sure this saved me a lot money and weeks without a TV!

Omg. I couldn't believe it at first but this worked for my TCL55PUS too... Thank you so much sir for sharing your knowledge with us. My issue was with the left side so I had to do it with the other ribbon like what others said. It was really hard for me to carry this whole TV by myself as a petite girl and I almost cried trying to unmount then remount it back on the wall cause it was so heavy and it was so hard to position it in place without seeing the wall. Not to mention the difficulty of actually unscrewing everything and doing the fix. By the time I got to the taping part I was sooo exhausted and hopeless I just did what I could and prayed to God it would work and thank God it did. Honestly it may sound pathetic but this is one of the hardest things I've done in my life. But I managed to do it thanks to this awesome awesome video and even more awesome uploader. Omg I could cry. 😭😭😭Thank you so much dear Mr uploader. You saved me!!! I hope you get a million more subs and billions more views. ❤️❤️❤️ May you be blessed with everything you need all the days of your life. I am truly grateful sir 🙏🙏🙏

This worked on my nearly 4 year old TCL 55". It started doing the same thing on the right side of the panel yesterday. One thing that's not mentioned is there's A LOT of screws to remove. Best to mark the pins on the ribbon cable with a fine point Sharpie first. This will give you a better idea of the width of tape to cut. I used electrical tape and believe me it's NOT easy. I didn't get it perfect the first try but using the tip of an Exacto blade to slighlty shift the tape left/right I managed to finally get 12 and 13 covered. Thank you very much for the video, you saved me $ and aggravation!

Hey! I just want to thank you for taking the time to make this video. I tried this and it worked like a charm. Finding 12 and 13 was not easy and it was even more difficult to put the tape on. But I'm so glad we live in a time and age where people from different parts of the globe can share their knowledge in this manner. Many prayers and blessings from my side to you! Thank you!

Wow, thank you so much. Quite possibly the best 4 minute video on YT I have ever seen. I was prepared to purchase a new TV, chalking it up to burn-in or just a cheap TV. A tip for when I was straining my eyes looking for the 12 & 13th pin - I took a 2x picture on my Iphone and then zoomed in when viewing the picture to blow it up, luckily my cable had blue markings every 5-6 pins that i could use as reference and the 12th pin happen to sit right below one of the blue dots. I used standard scotch tape and cut it with sharp kitchen shears. Thank you!

This fix worked like a charm for my TCL 55S405. The wiring is a little different on my model, but the idea is the same. Not sure how you figured this out, but I’m glad you did. Thanks!

Bro it actually worked on my 3 year old TCL!! You saved me a lot of money. I'm subscribing to your channel now. Thank you for this info brother! Real Life Saver!

I just did this fix 20 minutes ago. I fixed a Canadian 55R617 (55 inch series 5 I bought in 2020). The ribbon in question was on the T Con board which is located at the bottom middle of the unit when you get the back off. Same idea, count in from the left on the cable until you hit 12/13 and lay down the tape. Took a few tries to get the position right, but it works!

Big ups my guy! My TV setup was similar to other users with one main picture ribbon that then went to 2 ribbons. The left side was my issue so I followed directions from other commentors. Definitely a precision job but all I can say for others is don't give up! Took several tries but the issue is gone! Thanks again!

Thank you for sharing the fix. Was the greatest tip to fix the TV flickering issue. I had the same flickering on the right side in Jun-2024 for my HCL Roku TV. Based on the comments, this looks like a wide spread issue for TCL . Fixed with tape like a charm. Used phone camera to put the tap on 12 and 13 pins. Difficult part was removing so many screws on the back of the TV and putting them back. All my friends think now I am an TV expert. Thanks again. Saved me a lot of trouble and money. Love from Canada.

Thank you so much sir. It really worked. It was a bit difficult to identify the pins 68th and 69 th and taping them correctly. It completely stopped flickering on the left side while viewing on the front side of the LED TV. You have saved lot of money. This stickering also stopped grey lines appearing on the screen also. Thank you once again.

It actually works.. thanks bro! Successful after 3 attempts switching on and off the tv to check. First 2 attempts of using overlapping scotch tapes didn't work. Finally works when I used a masking tape over the 2 layers of tape to fully block the connection. Easier to cut the tapes using penknife and cutting board. And magnifying glass to count the 12th and 13th strip.

Wow, can't believe this worked. I have a TCL 55s423-CA. It's the same fix with the same pins. The only difference is the ribbon cables are at the bottom of the TV instead of in the middle! Thank you so much for the video!

Brother this fixed my flickering distorted purple image I taped a few pins clamped the one ribbon and it’s gone holy shit I can’t believe it god bless you thank you for this video you’re a life saver brother much love!!

Crazy. It works. Very hard counting the pins and getting the tape on. I asked a family member with more delicate hands and they could do it. It absolutely works though. The flickering stopped. Thank you so much.

One year has passed and this trick is still working. Thank you sir!

I have no words!! Saved me a lot of bucks!! I have no idea where you learnt it, but thank you for sharing it online!! It worked like magic!!

Oh man! You're an absolute legend! Covering pins 67+68 worked on my Mi TV 4X (55). I think it might be pins 12+13 if it's a problem on the right side of the panel and 67+68 if it's the left side. Not sure though, but mine was blinking on the left side. Thank you so very much. You really saved me and all these people a packet of money! God bless you! Keep up the good work.

Just worked on my TCL 2019 55" 4k. Incredible fix! Saved me the cost of a new tv!

Thank You so much brother. I had same issue and for that I found this video. Counting and Taping are the hard part, but what I was mistaking was correctly putting ribbon back on its exact spot. It worked third time and my flickering in my Mi TV was completely resolved. Again Thank you for sharing this video.

Thank you for posting this!! I couldn’t stand watching my TV and no other solutions worked. I did the 68th / 69th pin (from another comment) on the other side since it was my left side. Took me less than an hour. 🤘🏼🤘🏼🤘🏼

Same issue happened to me today .. exact ditto.. and man I don't have words how to thank you. It worked so well and it's back to normal . All thanks to you . Take a bow !!! 👍🏼

Sir I cannot thank you enough for this video, it took me a few tries to get it right and i was almost about to give up but what worked for me was that I tried covering one pin to the right and to the left of the 12th and 13th pin using a masking tape. Bless you for saving all of us a whole alot of money!!!

this worked for me like a charm. ❤ thank you so much for this video. saved me from buying a new tv. customer service charged 300 for a visit and said to throw it and buy a new one. 😮

Hey! This 100% worked and I’m so grateful for the time put into this fix, and the video. Only fix I’ve found that worked! Well done and thanks for the tip. Note. Mine is a 55” tcl and the wire ribbons were located and arranged differently than in this video - but I looked for where I could find the “1-80” numbers marked and found it under a panel on the bottom. Removed panel, counted in to 12&13 and it totally worked. First go I saw a pink vertical bar but adjusted and it worked. Thanks again!

After multiple tries, it worked! Thank you so much, brother! You saved us a lot of money. Our problem is on the left side of the screen and we used masking tape to block the 68th and 69th pin, took us two hours. Thank you! 🙏🏻

You are saviour! Tried this with my Android TV which has huge problem than this and it worked! Thanks 🙏

Alright I managed to fix it for those TVs with only 1 ribbon cable when opening the main plastic compartment. You HAVE to open the bottom plastic cover to be able to see those 2 ribbon cables because the main plastic cover doesn't show the 2 cables, only one! Managed to fix it first try using the video shown here. Same method, you have to put tape on Pin 12 and 13 with the black isolation tape that came all over the TV. I have a Xiaomi Mi Tv 55' 4s Edit: thanks to the uploader for the tip and actually share it with everyone for free! Without this, people would have bought a new TV. Who says hero's wear capes!! A big thanks to you kind sir

THANK YOU, THANK YOU, THANK YOU. It worked!!! I was ready to junk my TV and buy a new one. There are several videos online that say to unplug and plug it back in, reset, adjust this or that and none work. This did! I most definitely have subscribed!!!

Wow I didn't expect i would find a video addressing this problem. Facing the same trouble with my TCL tv. Thanks for the video!

This thing works in a TCL 55 4k! Thank you mate, you saved me some hundreds!

This actually freakin worked!! My TCL HAD THE 2 ribbons at the bottom (near the infrared sensor). Sure enough, took some time to get the tape sliver thin enough, applied on the end of an exacto knife with the help of iphone magnifier on a stand. But wow. 🙏👍👍

Man i love you, i was about to buy another tv and bro you saved me thanks so much man you are a blessing

Thank you!! Sorted mine out finally!!

finally my tv is blinking off At first I did not understand, saw the comments of others and then understood, then I tried and it was done.😇🤗☺Thank you so much 💌💜

Great job. I had to do something similar. It’s usually a blown pixel messing with the clock signal. Blocking off one the pins bypasses this. If you look closely at your screen you may notice one pixel line greyed out, but the rest of the screen works perfectly well. TCL panels seem to have this issue, BOE and AU Optronics panels seem spared. Good job making this content accessible.

Thanks for the video! Here are a few tips that worked for me. 1. Left side of the tv flickered so had to pull out the opposite ribbon to the one in this video. Then tape pins 68 and 69 (like others have said) 2. Counted the pins by listening to an exacto blade go over each one. Was much easier to count the clicking sound and feel than counting just with eyes. 3. I put blue marker on the tape so I could see the tape better and make sure I covered correct pins. Really happy I found this video. Now just have to wait and see if the right side fails too. Not a good sign there have been so many people with this problem. TCL👎

Hello sir. Very informative and helpful video. I have black horizontal flickering Line on the top right of my tcl. What pins are associated to that part? Thank you

Thankyou so much sir...i was facing this issue my full screen was getting dim and bright...i fixed it by your method.... thankyou once again for your information it was really very helpful

Hi this fixed my flickering problem thanks so much I still have horizontal lines at the top and bottom of the screen and now the right side is not as sharp looking as the right but is very useable but I would like to know which pins are responsible for that

Man.. cant thank u enough.. it works...it was difficult .. preferable to have good lighting and a magnifier... the video is very helpfull!!! Thanks again

Thanks for posting a valuable video that solve the issue for many of us. My question is that what about top side of display flickering exactly same as your tv? My tv display flickering from top side. Thanks

Hello! Thanks for the video. What would be the solution besides taping (actually replacing the faulty component). Which component would it be? Thanks!

Thank you! It worked for me on my TCL 55". Fortunately, I had a macro lens for my cell phone camera, otherwise my 70 year old eyes would not have seen the pins.

My Roku 55" TCL 55C803 4K UHD HDR has the problem where the top 1/2 or 1/3 of the screen has continual rolling up of a lighter screen. Any suggestions? The TV is about 5 years old. I went thru troubleshooting with TCL to no avail. Thx

Omg got a free 55 tcl TV and fixed it in one day from this video ... thanks so much ... appreciate the video

Thankyou so much for this bro. I fixed my TCL tv with this method. But my issue was with left side of the tv flickering. So i taped 12th and 13th pin of the other ribbon connector. Please note u have to count from the opposite side for left side issue

how to tape it ? i want to know we have to apply the tap in upper layer or the ribbon pin itself ?

@RadnusTechnology thank you so much for this useful tip. Worked on my TCL 55P6US TV which had a flicker on the LH side. A slightly different circuit but the technique remains the same. Need a lot of of patience and perseverance to put the tape on, but once you get it right, the sense of achievement is absolutely great.

So amazing! It works on my 55P6US. I've subscribed your channel. Thanks a lot again!!

It's worked! 🎉 mine is the left side of the screen, hard to count the pin, but I did it anyways and it worked, if yours is left side just count from left to right pin 12-13 cover both with masking tape, that you so bro 🥳

This worked for my Iffalcon 55k2a TV too. Though I'm not sure enough that I've taped the exact 12 &13 pin as it was really tough to pin point them. However it worked for my TV. Thanks for the video guide.

4/2023, Element TV. I was beyond skeptical but this actually worked!

Thanks a lot bro , solved the issue . Though searching for 12 & 13 pin was tough . Black tape did my job .cutting such thin tape and pasting was tough though . Thanks a lot for such guiding and descriptive video

What does the 12th and 13th ribbon do? My tv has the same issue and I am going to work on it today.

I have a TCL 55DC748. For a while it showed the same small icon, your screen shows in the bottom left corner. A white square with three slashes and a red box in the top right corner of the white box. It flashes. Initially I got rid of it by unplugging the tv for 10 minutes and plugging it back in. This would be ok for a week and then it would return. Now my screen has started flicking, then it had a complete scrambled screen. Again, I turned off, left it for a while and turned back on. The screen had stabilised but every other day the problem returns. The icon in the bottom left corner remains until I turn it off for 10 minutes or so. How did you get ride of the icon in the bottom left corner?

Just pulled my TCL off the wall and taped the 12th and 13th contacts on the right screen ribbon. Worked like a CHARM! Thanks for putting this video up, sooooo tired of seeing my TV flicker! Your instructions are so clear that I was able to pull it off first try, but man those ribbon contacts are super small.

Good day! How did you know the defective is 12 & 13??

You are a genius ❤️. It worked absolutely fine. I followed all your steps. Thanks for saving my 25000. 🙏🙏

My problem is from left side flickering ,I blocked pin number 67 and 68 it works for me . Thanks so much

This just happened to me, and voila, this video saved my TV. Many thanks for your help!

Hi do you have a technical explanation why this works?

My left side was flickering Much much much thanks after trying 8 times I accurately applied tape to 12 and 13th pin and wallah it's working like a charm Thankssss love from Pakistan

What type tape you use to solve this problem tell me

maybe you can tell me wich flex black or white and wich pins will work in TCL U55C7026 will work your method?

Aloha I have a TCL TV it is slightly different to yours , mine has 100 pins on each ribbon cable do you know if the same pins 12 & 13 work on the wider ribbon cable . Thanks

Posted my comment in the wrong section. Moved it here. Original comment below. Hey! Wanted to say thank you so much! I'm extremely glad I found your video! You saved me a couple hundred USD. Your fix seems to have solved my flickering issue on the right side of my 55inch TCL Roku tv. Hope this fix lasts. Thank you again. P.s. How did you know it was pins 12 & 13? And what do they control? I'm very curious.

Thanks a lot man, i taped number 12 and 13 as you said works like a charm ! TCL 55p8M

Please help me with my tv. My problem is the top portion on both sides left and right which pins i need to tape.

Getting the same issue but on the left side of the screen. Any help with the pin selection for the left side?

Fixed my TV just following this video. Saved me a bunch of money! 10/10 would recommend everybody facing the same issue to try this

My TV is doing this. I'm going to have to try this. What do pins 12 & 13 do?

I'll try this as well. My TCL started doing this 2 weeks after the warranty expired. Crazy.

A minha tv está com o mesmo problema.Como vc identificou o problema. E como marcou ?

@RadnusTechnology my tv is flickering on the right side and its a samsung tv what should i do?

Hi everyone! I saw it worked for a lot of you guys, but Im not tu sure how to do it in my TCL L55C2 TV. I only have one 51 pins cable getting out from the main Board and connecting to a board in the bottom of the TV. From this small board I found an 80 pins cable that connects to another small board on the right. I mean, as I saw on the video I was expecting two 80 pins cable... I tried tapping pins 12 & 13 from on the connectors but it diidnt work. Also, its looks like more than the middle of the screen is flickering, does this solution applies? Thanks very much.

Hi, can you please tell me what pins 12 & 13 were called on the tcon as I have a similar issue with a different tv.

It actually worked. Mine was a Xiaomi 55inch. Thanks man…

Thanks! This worked on my tv. I had a different setup with 2 short blue ribbons but it still worked.

Thanks, It actually worked. After a few tries able to mask the pins and it worked for my iffalcon 55 inch LED TV

Sir I have iffalcon tv 55 inch i have upper left side blinking so why pin have trap ?

I thought i need to spend thousands to resolve this issue! This helped me so much! Thanks much buddy! Btw how did u know it's 12 and 13th pin causing issues and covering those with tapes will cause difference in display clarity?

facing same issue on a samsung led tv, will the pin numbers be the same by any chance

I have the same issue, but I've got a doubt that y do we particularly select 12th and 13th pin? Jus for the sake of knowledge.......

I have VU 55inch TV and it got the same right side screen flickering issue. Can you please help in resolving this issue...

My TCL has these ribbons located at the bottom but they appear to be hardwored into the circuit board, no little flap that can be lifted to then pull the ribbon out. Any solutions for this? TIA

Hello sir i am also having the same problem with the screen but it is on the left side what should i do please help me 🙏🏾 😥

I can't do it!!! Thank very much for the video though. It seems to have helped a lot of people with the same problem.

Would you do the same thing if it was the entire TV and not just one side?

I have yet to try this "fix", maybe tomorrow. However what are pins 12 and 13 actually for? I assume they are meant to do something, so disabling them by covering them has no negative impact? Just curious

Hi. I have a doubt my tv flickers from center to top. So for this how to find which pins to tape? Thank you

Very good bro, this works in Sony bravia kdl led tv also numbers 12 and 13? Cheers bro

Cool stuff! Will do it on my xiaomi q1e later. Dont know either its will work or not. Btw what is the logic behind it? And does pin 12 and 13 is just unnecessary or there is something we will lose atfer not using it?

Good info brother, Is this work for left half too By tapping 12 & 13 in laft ribban

Thank you so much! You saved my 55" TCL ❤

Sir thank you for sharing your video, but how about from the bottom side its flickering?

It actually works also on Xiaomi TV. Thank you! It just saved my TV

Does this work on a p8m model ? Mine just being doing the flickering since one week
