TCL TV Screen Blinking Flicker Issue Fixed!

[@RichBolstridge]

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 KZbin!! 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!

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!

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.

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.

[@MrJoshuahenry]

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👎

[@RadnusTechnology]

Hello, that's right, just scotch tape over the pins. Tested for about 2 weeks, no issues. Heat at the ribbon should be minimum, keeping fingers crossed. Those pins probably corresspond to Backlight auto adjustment functions which started malfunctioning causing the flicker and taping the pins disables that function altogether.

I read in the comments of other YT clips on this that this requires a hardware replacement. Which part? I assume that taping pins on the ribbons leading to the T con (timing control) board disrupts the signals of the respective circuits from reaching this board thereby not engaging whatever component is faulty. So, is it highly likely that the T con board is faulty? And is it sensible to simply replace it? I have seen prices in the $30-35 range for a T con board. That's incredibly affordable and a much better option than paying a repair shop or getting 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.

Hello, I would like to know if this is just a temporary fix and if so, what would be the proper way of fixing it? Will I have to replace the t-con board?

[@NeMeSis7PT]

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

could you just replace the ribbon cable? Or not?

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

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.

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?

When you are saying that you need to tape the 12th and 13th pins, what do you mean exactly ?

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

[@RETR0CADE]

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.

[@RadnusTechnology]

Hello, glad to know that your TV display issue is now fixed. Thanks for sharing your experience. With regards to the pins, each pin controls a different function of the display and the flicker issue is related to malfunctioning of the automatic backlight control and by taping the pins that control this feature we are in a way disabling the feature that is malfunctioning. You will still be able to control the backlight through settings.

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?

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

[@sunnyrajkeshri]

Will you clarify me one thing? Is is an issue with the ribbon or a circuit board problem? I am getting this 80 pin ribbon on amazon so if i replace the ribbon will it work or taping is the only solution. My tv is now out of warranty so i dont want to call service centre they will charge more

[@gadgetsobsession]

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?
