- This next repair is how to replace an edge-type backlight of a LED tv and know what causing it to fail. Tips and tricks. Please support my channel and follow my Facebook page. profile.php?... thanks
Great video. Yes the first thing I do when setting up a new LED set is to turn the backlight down as low as I can tolerate - on some TVs it looks fine with the back light at minimum and this will certainly make it last much longer.

Good fix Mr Tevz. The quality and techniques are very functional. Thanks for sharing your own methods.👏👍🙏🙋♂️
Thanks for the video... That's tv so large are very difficult to manipulate. 👍
Difficult operation, well done.
Please pay more attention! ! Perfect well made repair video.
Thank you for sharing this! I have an LG 65SJ8000(edge lit) 2017 model with the same shadow emitting from the bottom of screen. I'm hoping to repair it myself with the help of this video! 🤙🏿
Your videos are very helpful
Bom serviço, tenho pego muitas desse tipo de tv com o acrílico rachado.
When i replacing backlights in most of the cases if this is possible to be done i try to modify the driver circuit according to the pdf datasheet of the driver chip to have lower current to the leds to prolong their lifetime.
sir exelint information video good works

I had one and the led's were working, but the melty diffusor created darker patches. I think it must be replaced or maybe it could be polished out so it doesn't darken the light. I just ended up throwing it away..the replacement leds are too expensive. btw, I think it will just melt again, these leds get REALLY hot, I turned it on when disassembled, and you can burn your finger just touching them after they are one for more than less than a minute.
Very nice video sir
Good job 👏 👍 👌
Ur video is great
Tnxd❤
Hello you could turn the diffuser upside down and you will having no problem, keep this in mind for the next smart tv in rest very nice wok.
its a 1 way light
Nnice job ,salute
TKQ , pse advise what is the simple ways of checking back lite LED and supply
I put it the diffueser upside down, I see other comments as well about it. The reason why it's faulty, it's because they are allowed to build it in type of quality ;). And SHARP from what I remember is made by Vestel. You can't expect a quality from Vestel TVs IMHO. So, buy a Sony if you'd like to have a quality ;). Less backlights I replace in them.
Thats a lot of hard work i thought LCD leds was hard work .... Kudo's
This same problem happens to Samsung edge lit tvs also. Bad design. 100% backlight = catastrophic failure later

On your next repair like this try to flip the acrylic glass upside down. That is you put the top edge at the bottom. You may have to remove tape from the top edge. Also dark areas on the glass may be smoke stain. Try remove with soap cloth and clean properly. Sometime the LED fail because glass is touching the LEDs causing damage to one or more, then the others fail. You also need to check the spacer that seperate the glass sheet from the LEDs. The space may be ok when the TV is flat on it back but may touch when TV is place in the upright position.
I try flipping the acrylic before, but not work,
@@tevzTVTevatronics Right..... they are internaly polaraized and only distribute the light in that position good work sansung sharp etc trash tvs they make then for fail and burn in 1 to 2 years, tevz i see one sansung who burned so bad the acrilic they afect the lcd to with hot. Is good to change the resistores from 1.5 ohoms in the power suplay for 5 or 6 ohoms the leds goone live more time. Unfortunatly the Brands not advice the costumers and let the product go out without telling to clients they must protect the backlight using always much less backlight settings people always want brighter and brighter contrast etc, they do not limit the leds to the correct values 1 or to ohmos are always much more volts in that lights generaly 5 or 8 volts more so a 10 ohmos resistor is better protection.
I use always my tvs away from windows and hot devices sun etc and reduce de backlight at 60% settings and i have two Lg one 7 years and other 3 years and no fail leds and LG is champion in burning leds lol. Thanks for your great videos Tevz you are amazing.
You cannot flip the panel, light distribution will be different and most have edge tabs cut into them so it can only be fitted in one direction
On the similar TV what's wrong if the led are good but they illuminate only for few minutes them off
could u just flip the difuser sheet 180 and leave the burnt at the top of the tv
Good boy
Hello Tevz, I must thank you for sharing your experience. I am a repairman for industrial electronics, mostly. Greetings from Paco, yous spanish fan. By the way, where are you from ?
Philipines
I have problem with TV, backlight turns of after 5 minuts. Can you tell me what i need to check? Thank you
????? What is the back
Light for. Is it really necessary??? I’m new thank you

I watch it all the time. Thank you for your interesting video. I'm repairing a TCL 4K 43V TV. The image is displayed, but some vertical lines are dark. I disassembled it, but the edge backlight was normal. Is it because of T-CON? Please help me.
The vertical line is not the backlight problem, It's the panel. also not the T-con.
@@tevzTVTevatronics thank you for your reply. I would like you to judge from the photo, but is it possible to send the image?
Күшті👌
👍👍🌹
Sir this broblem solved. Broken 50" Tv Tefuser sheet laser cutting .
I hate this placing mode of the ledstrips. When You change the bad strips, the light will not be the same as the original lights.
Hi Mr tevz.what a bad kind backlights they are?
But your work was great and useful.
I wish to tell us the voltage of each backlight.
I fixed a sharp led tv backlight that there were about 103 LEDs. B. L at 8.5 volts for each one.
Thanks al lot.
they are 6 volts
There’s no 8 v leds - 6 volts and 3 volts
Mr tevz may be you donot believe me but it is truth.
I was wonder when I checked them for several times and you can research about that. If you are interested in it.
i write the model number for you.!
Lc-40LE700M-Sharp tv
Something else must say:
On the backcover of the tv is written lcd but when the cover is removed you will see an led tv system!!!
By the the way some of my friend also do not believe that there are such a volt led but when they check themself they were surprised of seeing that!!!
Ofcourse I replaced 6 volt lead and it works but another on at the same model number it does not cos abut 10 leds were replaced and the light of leds are too low and we could not fix it yet!!!
@@sarockpashotan maybe the LEDs are changed voltage due to heat for a long time. I don't really have encountered an 8 volts single led bulb.,
@@ronaldmarcano5648i have encountered 8v led too, but in a phillips led bulb..
Hi Mr I sorry I dnt get clear why led get damaged
Im having this kind of problem. When i switch picture mode to dynamics (hdr), the backlight is turning on. But when i switch picture mode to standard, the backlight keep blinking
frs
Original edje led strips not evelble in india only duplicate
the crooks that manufacture these tvs deliberately set dynamic range at its highest level to ensure premature failure.
Translate to Sinhala
never set Picture mode to Dynamic
better keep Picture mode to Movie mode always
REASON DOESN'T MENTIONED!
here's the reason, czcams.com/video/4CerX2tOveY/video.html
NO ... REASON....BULLSHIT
