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.

@user-vn5zb5sc3m 2 месяца назад

Well damn you literally took the whole TV apart to do it.

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?

@brysonbumgardner5015 8 месяцев назад

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

@Matthew-in8db 28 дней назад

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?

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

@qcsbuilds5708 16 дней назад

I feel you if it's on 24/7 or 8 hours a day... yeah they don't last very long.

@unixbcn 6 месяцев назад

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?

@qcsbuilds5708 6 месяцев назад

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

@unixbcn 6 месяцев назад

@@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?

@qcsbuilds5708 6 месяцев назад

@@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.

@randomtube8226 Месяц назад

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 😔

@qcsbuilds5708 Месяц назад

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.

@randomtube8226 Месяц назад

@@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 🤔

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

What are you connecting the multimeter to when testing the LEDs?

It doesn't show picture at all? But it turns on correct?

@@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.

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....
