TCL 65" LED TV - No Backlight No Image LED Strip Install Replacement Models 65S4 

Found a 65 inch tlc on the side of the road, only thing wrong with it was the backlight. Bought all the tools/ back lights in this video for like 68 bucks. Followed the steps and now I have a huge tv for a fraction of the original price. You guys rock!

I know nothing of tvs. My teen boys and I followed your video step by step and we are super proud the TV is working. THANK YOU SO MUCH!!!!

I broke my 65' TLC, I would leave it on and it fried the LED strips. And this television was a gift and I didn't want to have to buy a new one. Your video helped me fix my tv and I'm so excited! Your video was easy to understand and I love that you took your time but didn't give needless commentary. Straight to the point! Thank you!!

Excellent. A very simple and straightforward video, and from the company I'm looking to buy the replacement parts from no less. Currently sitting on a 55" and a 65" TCL with the same dead backlight issue. Both died after a year and a half, literally within a day of each other.

This video has been upgraded, GREAT. Me being old school I thought the ribbon cable that hooks to the buffer board and looks like scotch tape was scotch tape and so I cut them with a razor knife. WHAT A BLUNDER. I ended up getting a air bubble in the screen, so I had to junk it. Glad it was mine.

Excellent! Just relolaces and worked like a charm! The ribbon cables that connect the buffer boards FLIPS UP. The black price flips up and ribbon pulls out.

This guy just saved me from tossing a $700 TV. Thank you!. Definitely had to rewatch the assembly when I thought I lost the little IR wire that snaps onto the board, didn't realize it was on the bufferboard thing. Thanks again!

Also, this video is great. Very straightforward, and not wasting time. Thank you, very much. Peace

Thanks for the instructional tutorial. Very thorough step-by-step instructions. Just repaired my 65" TCL tv. A few things I did different. I have read where several people have cracked their screen when trying to remove it from the top filter frame where it is glued together. So, I left it attached to the filter frame and removed them together. Used a couple tabs of painters tape at either end to help keep together. Also, I carefully removed the white reflective backing paper and put back with some Scotch double sided tape here and there. No cutting necessary. I don't know if it will make a difference in longevity of the LEDs but I put a dab of thermal paste under each LED when installing the new strips.

Awesome video thank you so much. With your help we fixed our tv. You rock!!

How you doing.Can you tell me what size doublesided thermal tape to use on led straps? Thank you.

The left and right sides have like a black film tape under the bezel holding the panel in, is that safe to cut, didnt see it on the other tvs ive done or in the video.

Do you put the little round, plastic parts on the new LED strip? If so, how are they attached? Peace

Hi do you have info how to remove bezel-less screen, the oe with no frame on top of them ?

Do you replace the paper that you cut out?

I used the video to replace the LEDs on my 65" TCL tv on November 11th. I notice last night that during streaming and when the tv has a darker screen when processing from from one episode to the other I am seeing lighter areas in the upper mid section of screen. I have an image on my phone and it is limited to about a 8" square area. Is this an issue you have seen? Or could the adhesive backing on the strips have come loose in the area?

저도 TCL65인치 사용중인데 소리만 나오고 화면이 안나오네요. 영상보고 따라해야겠어요.

What's the part number for the light? And how do I buy it from yall

What if you strip the screws around the bezzle

Does no image mean no image even if you hold a flashlight to the tv? How did you diagnose no image no backlight?

If we can increase the life of the LED backlight subsystem by changing the defaults of various TV, this would be a major benefit to users. Is there a BRIGHTNESS (e.g. 50%) and/or "PICTURE MODE" (low power) and so on that can significantly increase more than a year the amount of time before the LED subsystem fails? Example: default a 65 4series TV from Walmart Model 65S41 (which I THINK is equivalent to the 65S451) came with default brightness set to 100%. However, it is perfectly viewable at lower settings.

If one does happen to damage a fragile "buffer board" (note1)...is it a totally catastrophic failure issue, or is it an inactive component that can be fixed to a _"good enough"_ state with bonding material and/or splinting of some sort? note1: I've seen people misidentify simple mechanical strips without electronics/circuitry as "buffer boards" is why I'm asking.

How can I identify Aftron tv 55 inch?... I replaced the led and again it was damaged. What is it the problem plz? Firstly I have pictures with out backlight but second I don't have backlight and images and I can not test it the sound 📢 Plz let me know it

Seems that two screws hold the strips in place. On the ones that I removed there are some black material that also held the strips in place. Would that be thermal paste? Does the double sided tape need to be thermal or will any double sided tape do? Also, once the new strips are in place, is it okay to turn on the power to confirm that all led strips are working? Thanks for any replies?

This seems such a common problem on LED LCD TVs, that there would be a benefit to the industry and customers if there was a diagnostic that a single indicator (e.g. the on/off indicator) could be used during boot-up to affirm the LEDs are getting appropriate signals and power. With that information one could immediately determine if replacing one or more strips would fix the display. If an LED strip failure is detected, the same indicator in theory could be used to present a code that even IDs the specific failing strip or strips. The same could be used to check the output(s) of the LED power inverter.

Hi I have a vizio d60-f3 and I started having problems with the picture it's got a line going horizontal about half the screen still have picture but top half of the picture is darker than the bottom half

Where can i buy tv panel?

I have the same t.v. I have replaced the LED strips, main board and the power supply board and still have no LED backlights? there is no voltage at the power supply to the LED's even though its a brand new board. any ideas as to what im missing?

Hi, my 65 inche tv is showing light black what can I do

Gonna try this, just ordered my lights. What suction cups are those?

I am trying to locate the clear plastic IR beam sensor cover for a TCL 65" tv (65S421). Mine is broken and I cannot locate a replacement or even the part number. Help.

👍👍

We replaced our TCL backlights and the TV just blinks one time and still no picture. We can see words on the screen if we hold a light next to the screw. Do you have any other suggestions to try?

Question i have the tlc 65s421. I can see the picture menu etc with a flashlight or from an angle. How do i know its the led strips or the inverter?

After replacing lights we now have bright spots in pictures with white coloring. How can we fix this?

Why do you need to use double sided tape if they are held in by screws ?

I have a 55” Insignia - no sound and Black screen. I used the flashlight “nothing”.

while this video is helpful i think it's safe to assume there are some other reason for a no backlight situation, having a professional show the diagnosis process to confirm it is an led failure and not a board component failure before doing the risky full disassembly would have been nice....

I'm REALLY curious how hard it will be to fix a TCL 6 series with mini-LEDs

I had a hard time putting the bezel back on. I guess the screen wasnt perfectly aligned, so the bezel chipped the corner of it. It was a tiny crack, but it somehow sent it all the way down to the other corner. Upon putting it back together, the entire screen is fried. So fml. Also, it took me like 4 hours. U guess im just not too savy.

Cracked my screen. Giving up. Sending led back

Replaced LED strips in my TCL 65s423, I had no backlight but could make out the Roku image on the screen prior to replacement. After replacement, I have the same issue. Could it be the screen and buffer boards that is bad?

Don’t do what I did. Be careful not to scratch or touch (with bare hands) the transparent screen behind the display screen. It will show when you turn the TV on now I must live with my mistake. Thankfully I saved the TV from being tossed and only paid $36 for the LEDs to fix it, and 2 hours of my time.

MAKE SURE YOU DONT GET DIRT TRAPPED IN DIFUSION PAPER lol I now have a spec but on the bright side tv is fixed

If it's going to malfunction, I don't want it.

This is going to be a pain in the balls

Man, my 65S434 looks nothing like this haha (mfg Sept 2020)

My tv has no led strips, only a sheet of glass

Do not cut the backlight paper covers you will see lines in your picture!!!

Concise. However, your voice was so monotone I actually fell asleep. Currently leaving this comment instead of hurrying up and getting ready for work.

Too much work to repair a $230.65 inch TV from Walmart 😂

f

Anyone need some lights? I bought 2 sets by accident.

I've seen other videos where they've just taken out those black strips and tested them to see where the screen is gone black now all of a sudden this guy is taking the whole screen apart it doesn't make any sense to me seems like an awful lot of work I pay $289 for my TV if I'm going to have to work on it for 4 hours and I'm going to have to order stuff from them that's going to cost me over $100 in 3 weeks where's my do-it-yourself save money thing?
