E469119 strip in in 32 inch LED tv, it consists of 7 LED in each strip and total 3 strip, all of them are in series. i explained how to test this it using digital multimeter specially when we dont have LED backlight tester. so without led tester we can use multimeter, 3.6 volt battery or 9 volt battery or using a regulated power supply. and we can replace strip or we can repair individual led

Thank you for sharing this video. 👍. I would recommend to replace the entire strips instead of single LEDs. Otherwise you will do this repair again and again on remaining old LEDs.
What do you mean entire strips??
The whole old backlights ?
@@jn9550 I mean the complete white lines. There are new ones available for most TVs and it make sense to replace it complete, because of the effort to open the TV display.
@@hugoegon8148 the enti6tv Backlight ( whole Backlights) ?
@@hugoegon8148yes make sense I broke the led panel while opening my entire exercise went waste had to throw 4 years old Philips tv
@@Jam-sh8oj Oh je, thats a pity. But it happens very easily, especially if the LCD panel is only lying in the case frame and very fragile. Cheap manufacrured, but nearly impossible to repair. 🤨

Thanks for sharing this video brother

I especially like watching the repair videos. Very helpful...
Fantastic tutorial video Haseeb. You are doing a good job
Thank you for the video. I have a LG 60 inch screen that went very dim but not dark. Before I make a mess of things is this a partially open LED issue? Are all of the strips is series with each other or are there multiple circuits? It seems on your TV the strips failed one at a time or did the four LEDs all fail at the same time, possibly from a power surge?
Very good janab duwa ha ap khush rahy
very informative, keep up the great vids Haseeb,
Great ..
Really super professional
YES two options are there repairing or replacing

Very Nice Sharing Bhai Jan
What were you using to remove the leds? It looked like a basic soldering iron but what was that noise, was that actually a desoldering iron? It didn't look like it.
I'm wondering if I should buy a backlight tester or if I should just buy a benchtop power supply?
Excellent information
Even if leds light with an applied voltage, could there still be a rouge led that requires extra current and the tv power supply cannot deliver this current?
Do these TV's have a max current that they will not deliver above?
Hi haseeb,why wont the universal 12v backlights not work in my tvs? But when i test the lights with backlight tester they all go on.
Wa aliqumuslaam informative upload

nice sharing...
stay connecting....
is it possible to replace only 1 broken led instead of the entire strip? if so, what is the led reference? any led with 3v will do? or does it depend on tv brand and model?
Thanks for sharing your knowledge... And the tips..
it is my pleasure
very informative my frd
Good sharing
Is there a link for the LED's, I am not sure what they are (note: not the LED strips which cost $70.00). I have the VIZIO E50x-E1 TV.
Fantastic. For the testing idea
it is my pleasure
you can also check video number 556

My friend i would like to ask what is the name of connector from led to main board the white one with 2 pin
thank you
Brilliant idea - Thank you
You’re welcome 😊
Haseeb, What current do these draw on the 3v power supply?
Sir,i have a LED TV backlight with two led strips faulty,i remove it, but didn't soldier the bad legs of the two bad ones together,i fix it but didn't bring backlight of others... should i soldier the two bad ones just like you did in the video for testing,and will it not look like fuse reading when i do that.
Thank You Sir! It is very helpful.

My LEDs seems to be working when I checked with multimeter but when I connected power none of the LEDs light up. What else could be the possible issue.
Did you make that hot air gun?

Thanking u sir
Do you need LCD TV backlight belt?

After replacing the LED one can paint the darkened strip area with white paint to reflect the light again.
Nice
will the tv work normaly with shortened led soldier points instead changing like you did for testing?
shorted led points will cause to blur or dark display in that specific area of the display panel
سلام و علیکم It would be best if you brother، show the picture after remount the TV set to show how is qualificatio of the picture, I.m shure, it will works ?!, the idea is very good , but how it will be
Gjb
Thanks for teaching, great job.
So i followed all instructions and replaced bad LED's. Once i turned it on all lights ligted up and then TV went to stand by again, checked LED went bad again.
Changed 2-nd time and same LED's went bad again.( Insignia TV).
Can you tell me what went wrong and how to test it? Thanks.
.can you please check video number 566 and 565
might be replaced LED is not with current matching
or may be the LED driver is uncontrolled, (feeding over voltage to the LED strips)
Voltage is same, i have LED tester.
"feeding over voltage to the LED strips" ??
How to check it and what to check it? I have multimeter.
Thanks.
Big like
I have a question. I’m looking for individual led lights any help would be appreciated.

Cette vidéo de montre pas le moment où la TV est tombée de nouveau en panne quelques jours plus tard. Pourquoi le remplacement seul des LED HS ne fonctionne que durant une période limitée ? Pourquoi ce sont d'autres LED qui claquent successivement ? Pourquoi faut-il en réalité remplacer toutes les barres de LED pour que la TV fonctionne de manière pérenne ?
Sir, please if power ic is burnt and you cant find the part no. or equivalent, how can you modify it
@@HaseebElectronics Sir please i meant the power ic (PWM) in the SMPS
