how to test Repair LED strip in in 32 inch LED tv, it consists of 2 LED strips ad each strip have 6 LEDs. both strips 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

Finally someone who fixes the problem instead of replacing the entire strip. Excellent tutorial. I'm going to do this to fix a TV I found discarded. Thank you very much for posting this. Very easy to hear you and follow the instruction. No nonsense.
Really enjoy your channel, thanks for sharing your vast knowledge and experience without using very expensive test equipment.
Thank you very much!
I like the lamp method.. most people don't think about before sodering gun.
Thank you again for sharing your knowledge i allways enjoy spending time at the workbench with Haseeb
it is my pleasure

You are doing wonderful job to spread the technical knowledge.
Another beautiful DIY tutorial. I would love to convert my old LCD screen that uses CCFLs which are impossible to find, to Led backlighting. However, suitable Led strips are also hard to locate. May I humbly request for your expert advice? Thank you for the good work.
nice! im ur new subscriber frm the Philippines.
Good 👍👍👋
thanks a lot dear friend
Awesome. I enjoy your videos
best regards and special thanks
Mashallah great work stay blessed and stay connected💞👍🏻
Very nice videos. Never watched such videos before. Are you still at Azam chowk or else where.
thanks bhai
.i am in Jordan اردن
Great job Sir .
I wanted to ask you if i can just replace the LED under the glass with another LED !! i mean just change the LED inside then put back the glass !! if it is possible what kind of LED should i buy !! is it 3535 or 3528 ?
thank you
best regards
yes we can replace led 2835 3volt or 2835 6 volt
watt rating depends on the led strip 1, 2 or 3 watt
and we can use existing lense
bravo bravo
excellent
Many many thanks
Thank you sir.
Most welcome
Thank u very much sir may Almighty Allah bless u. Please sir what is the meaning of information written on the led light?
it is JLD42641330-003CS led strip
Good sharing bai
Salam alequm. Do you have a way to fix burn diffusers?

Hello dear professor
Thank you for your very good training
Can you please analyze the Green model computer power circuit?
thank you very much
welcome brother.
yes i recorded that ATX before yesterday. it is in editing process. in 2-3 days it will be uploaded
@@HaseebElectronics thank you sir 🤗🤗🤗
Nice g
Nice ...but soldring is good enough???
yes that is doable but soldering is not much effective on these aluminium strips, as these strips cool down the soldering iron,
by this technique it makes best soldering without damaging the mounting and LED structure
it is very cheap and very very useful
@@HaseebElectronics yes you are right this process does not damage the led but this soldring is not good enough for continuous running led ...I already do that...... please share some other healthy led soldring techniques .... thanks 👍🏻
IS the lens just glued on? how was it reinstalled?
it is push locked with guide points, and then glued
i apply super glue
Sir please give solution for my 3 questions
1) how to fix LED lense(dome shaped).?
2) you used liquid solder, can I use normal soldering wire to fix LED.
3) I have 39 inch faulty croma led tv , how do I know which type of LED is required (volt), can I use any type of LED to repair.
Ty for sharing
Marvelous.
best regards and special thanks
informative video ❤❤
Most of my reflection glass has fallen of do I stick it back with glue and if my led is not working can I take it from a led strip by cutting that stop led to fit
yes it can be done
Can I test it with simple 9v battery
yes. you can test it using 9 volt battery by adding 330 ohms resistor in series
Hasseeb brother I need your help to buy microscope for pcb repair ,can you give me some advice?
Can I use any led to solder the defective led? (Say an led from an old light?)
yes we can
if temperature is observed properly (while soldering or removal)
excellent.unigue technigue
best regards
Sir battery eliminators ky bare mein video banaya
how to repair the power supply of that led strip on the power supply board ,,my power supply for led strip is faulty..it has no voltage reading,,
What is the effect of just bridging the spoilt led without replacement sir?
Good work very informative vidoe big like 👍
Thank you so much 🙂
What will be cost of replaced backlight of samsung tv?
It will vary from country to country
As in Pakistan price of 3 LED strips for 32 inch Samsung tv is just 4$
But same atrips here in Jordan are for 19$
Add minimum 2x time service charges in actual price
For example 19 + 38 = 57$
@@HaseebElectronics I am here in India.My tv is samsung 43 inch UA43N5300ARXXL.
Grazie maestro. 👍
thanks a lot
Hello !
I have a monitor with led backlight. The screen of this monitor is broken. I want to use the backlights as a light source. I want to turn the lights on and off with the help of a switch. How can I do it?
What is the Reason you connected with the 12ohm resistor?
that is current limiting resistance
i connected in series
please check upcoming video (video number 566) you will find a detailed answer for your question
@@HaseebElectronics does the multimeter have an internal resistor when using "led mode" ? Thank you
could you please make a lesson about pmw TEA1733 ?
it takes start up voltage direct from Ac line .so I am confusing about this pwm ic ....... thanks master .........
Can I ask what the exact purpose of the 1K resistor? Is for protecting the multimeter?
It is current limiting resistor
(Similarly we connect in series with LED or zener diodes)
Oh, I just read your reply to another similar comment/question that video 566 will have the explanation for my question so i'll look for it as I'm behind on watching your latest video uploads. 👍
@@HaseebElectronics Thank you for the explanation.
most welcome dear friend
Salam M Haseeb, great video ! Can you explain why the multimeter drop from 12v to 2.5v ? if no resistor used, what will happen ? thank you & salam aleilum.
Without resistor the will burn.
Note LED always need current limiting resistor.
best regards dear brother
please check upcoming video (video number 566) your detailed answer is there
How much repair charge in mechanic pls
What lamp is that? I could not understand
Can we use glue gun to join the circular thing on the strip?
no glue gun is not long life
super glue is good solution
Aadhi led lights kaam nahi kr rahi hein adhi jal rahi hein kia karein plz guide
81 like amazing
Do these strips have current limiting resistors built in?
No, But they are parallel.
Y didn't u use soldering iron or hot blower instead of lamp
it is much more useful technique
because the aluminium strip dissipate the heat from the soldering iron and hot air gun
but this method produces a quick and large heat to the stip and the LED remains safe
and this method works excellently
TV backlight factory welcomes inquiry
it is very difficult to put back the led.. there is very narrow space between the led terminals and it get shorted very easily
👌👌👌👍
special thanks
السلام علیکم جی
thanks a lot
What if the LED are 3v ,will you burn them using 12 V ??
He is well experienced, Moreover, technician knows about the voltage rating in the area he is working. Thanks
no it will not burn-out because i connected a current limiting resistor
please check upcoming video (video number 566) that is answer of your question
@@HaseebElectronics ok thanks
@@HaseebElectronics Thank you.
Sir app video phala urdu wala channal par dala kara
okay brother i will try

말씀하시는 언어가 독일어 맞나요?
Wattage of led diode in tv
it depends on the color temperature of LED. most of the time it is 1 Watt
MP-3030-2200-27-80 is 2700K
MP-3030-2200-65-80 is 6500K
these have 150 mA

TCL55P65US ki led repair ho sakti hai.? Aapka whatsapp plz.
I just went on a painful journey of testing and un soldering leds from a old TV backlight just for the screen not to work it was my fault thankfully it was a cheap TV I've had sitting in my closet for years I just wasted about 8 hours 😂
