Thank you so much for this informative video! My wife and I were able to revive a TCL 65" thanks to this guide in about an hour and a half.
My friends and I got together to help me fix my TCL TV. Admittingly the LEDs weren't actually dead when we got to them. But for whatever reason, reassembling it seemed to get it working again. Thank you for this tutorial! It was super helpful!!
@@AFoxOnTheInternet you might have a weak power supply or and intermittently failed LED that's dependent on temperature. Fingers crossed that it just needed a "stern talking to."
Well damn you literally took the whole TV apart to do it.
Video is great, and very informative, unfortunately I cracked the screen during re installation.....
Any website you recommend to replace it or is it a lost cause now?
For what it's worth, the backlights work now just scrambled picture due to cracked screen
I have a 55S525 and it seems to be quite different than this TV. The frame (except for the screwed in bottom that I removed) is one single metal piece with the screen and components seemingly set inside it. There’s no “bezel” to remove so now I’m stuck at how to remove the screen without damaging it as I do think it’s probably glued in somehow. When I lift up on with suction cups the attachments to the buffer (?) cables wants to go along for the ride. Edit: got them detached so that I can lift the screen is still stuck. Any tips?
@@notshylo some of the new LG and Samsung panels the glass is actually attached to the outer frame and so you have to pull the glass with the frame. Sometimes with these it's actually easier to take the whole thing apart face down and remove the back from the frame.
@@qcsbuilds5708 thank you 🙏 do you know if TCL was doing that as well? I think they used more adhesive to hold the screen in because they only surrounding frame for it is at the bottom. I will check the back and see if that works. Thank you!
Ok so I think because the screen on my tv doesn’t have any frame (except the bottom) holding it in that TCL was a lot more generous with the adhesive 😭
Used this video as a guide to successfully replace the backlights and power board in our TCL Roku 43S435 when the screen went black. We had sound, and using the flashlight test could tell there was a picture there, we just couldn't see it. We did not have any testing equipment to determine which was bad, the lights or the part of the power board that powers the lights; although from what I hear it was most likely the light strip. Since ours was a smaller TV it was slightly less complicated. Frame is all one piece, no tape around the edges to peel away, only 1 backlight strip. We did not have the suction cup glass lifting things, but were able to pick up the screen with our hands (not endorsing that, just fyi).
i can’t get the right end acrylic brackets to line back up into the holes (that hold up the LED strips. I’ve taken them off and adjusted but the last 3 don’t want to go in… any tips?
Thank you for your awesome help ❤
Are you installing a new power supply or reusing the same one ?
Are you an expert? It seems like every TCL TV I buy. Just after the warranty expires. The backlight goes out 🤔 There's a lot of fragile parts. I'm afraid of breaking something. For now I'm without a TV 😔
I don't know if I'd necessarily call myself an expert I just been working on TVs for 15 years. Tcl's if you run them 8 to 10 hours a day then more than likely the backlight is probably going to go out within the first two years. They're just not built the last forever. However they're not super hard to change the back lights out in The biggest thing is the glass. There's usually a little bit of adhesive holding the glass to the inner frame so you do have to be careful getting it separate.
@@qcsbuilds5708 I don't think I have what it takes to fix this TV. I'm stuck in between a rock and a hard place. I either pay someone to fix it or buy a new TV altogether 🤔
@@randomtube8226 well on a TCL you're probably better off just to buy a new one
I have learned my lesson and will never purchase a TCL television again. I bought a used Samsung television three years ago that was already three or four years old and have had 0 issues with it.
I bought Samsungs first certified 4k TV, and it just went out yesterday. Had it for well over a decade. I've yet to find another TV that offered the same level price to performance and longevity.
Thank you so much
I have the tcl 65s455. Backlights just failed. If i unplug tv and plug it in the screen will quickly flicker the 4k them back to dark. I can see screen with flash light. What backlights do i need to order from where?
Shopjimmy.com just put your model number in
Is it necessary to release the circuits and wires in the back? Is there a part of the panel connected to the backlight area?
@@kimjenkins4926 depends on the spacing of the mounting lugs for the TV. If the wall mount lugs are not spaced far enough apart the panel frame tends to be very flimsy, and will warp when you're trying to install the new back lights. You don't have to but sometimes it's better to take the 5 to 10 minutes and just do it.
Can you fix my 65 inch tcl tv please i miss using it
@@meelbilll5380 are you located in Idaho, Nevada, Utah, Oregon, Wyoming, or Montana?
Nailed it. Thanks for the Video.
Hi i have a tcl 65s405 the backlight is working but my screen is not displaying. I resetted the unit and it came on for a few minutes the my screen just faded away and went back to a blank black screen but the leds are working what can the issue be.Any help will be greatly appreciated
It's likely the t-conn board
@@qcsbuilds5708 thanks much will replace it and see if that works
I put in an antenna yesterday. And today it doesnt show picture. TV is about 7 years old. Did i break it connecting the cheap antenna or it was just time for it to break?
It doesn't show picture at all? But it turns on correct?
I did a back light replacement. The tv turns on and I can hear it but the screen is just black. I did crack the corner but not enough for the whole screen to be black
@qcsbuilds5708 yea. I can see the TV when I put flashlight from phone. It's a if it's dimmed all the way.
@@mpbeautyboss so you have a power supply or you got a backlight that's gone bad. It's coincidental it wouldn't have anything to do with the antenna.
@qcsbuilds5708 I'm going to plug it back and make sure before I throw it away. But I went and bought a new one 🫨
I just bought my TCL Roku tv not even 2 years ago and already the back light went out. It took me that long to save to get the tv. 😡 TCL should pay for cost of repairs to put in the new back light. As for now I am out over $800
I feel you if it's on 24/7 or 8 hours a day... yeah they don't last very long.
Great and instructive video. I followed the all process and now the tv works again but with some black vertical lines. Any idea what’s wrong?
Likely either you have an icee that's bad on your blower buffer board or one of your ribbon cables took damage during the glass removal. Unfortunately that's not repairable outside of the factory
@@qcsbuilds5708 you’re right. One of the ribbon cables (actually half of it) which comes from the glass, cut out from one of the small pcb which comes along the bottom of the panel. I ordered a kind of wire glue so when arrives i’ll try to stick again the ribbon cable, more for practice and educational purposes because i replaced already the tv with a new one.
In the past i had only Sony and Panasonic tv brands and never had an issue. I know leds can burn on any tv brand but in my TCL case took only 3 years and half. Do you think being a pure chinese brand the leds or materials in general are poorer quality than a japanese brand?
@@unixbcn I think it has more to do with the hour lifetime rating of the LEDs versus where they're made. The lower the end of TV that cheaper they're going to make the LEDs.
Know where I can get a screen replacement for 65s405LAAA?
You can't
What are you connecting the multimeter to when testing the LEDs?
Not using a multimeter I'm using a backlight tester. Shopjimmy.com tools
@@qcsbuilds5708 All good! I took a leap of faith without testing and just finished the replacement SUCCESSFULLY!!
Thank you for this guide!!!
I broke the screen
Mine is out and I cannot get anyone to fix it. Where are you located?😢
Filer, Idaho, USA
😢😢😢😢😢
Where are you located?
how much would this repair cost?
Depends, but likely between $250 and $400.
I did it myself and it cost me $100 anf about 2 hours
@qcsbuilds5708 that's the irony of these cheap 4K TVs the backlights barely last 2-4 years. Why get a $400 tv fixed for $400 when you could just buy another TV lol.
that's why I'm opting to fix it myself and if I break it oh well haha
Maybe you could film some of this from your neighbors house. The distance from your camera to the work you're doing is incredible! Maybe film it from the moon....
