- replacing the smd by dip led caused a sort of dark spot that can be seen only during high brightness scenes and clear white screen, i can live with that.

Ingenious. I learned a few things about samsung LED backlighting here. Thanks for sharing.
Wow, your burnt the sh*t out of the board, but the white-out did wonders...good job!
There was a much better way to fix this witout exposing the LED lamp to excessive he. Using a jumper LED strip about 2inches long. You can use can scrape the coating on the strip on each sie and sold a bare wire to each side. The strip gets the heat, not the LED. It's a good piggy way to do it and it works.
Thank you so much for sharing with us. I've fixed my Samsung TV by myself! Peace! \/
thank you for the tip of using the back of the strip on a soldering iron because I had been trying to use my headgun and no matter what it was a mess, and or using the soldering iron on the pos or neg side until it heated up enough that it would crack off and then do same for other side for it to slide away then clean up the contact points , yours seems much easier aha though it leaves a nasty balck mess aha
2 pcs of standard LEDs (3.3V/0.04A) instead 1W LED (3.3V/0.3A) = excellent. How many seconds it worked?
Buy complete set of LED strips at Ebay or ali (about 25-30$ for all set) - it is only correct solution.
nice technique I'm learning with you TV repair
ha ha ha
Thank you sir! Saved me a whole lotta money!
Well done!!!
They sell these compatible led strip bulbs. Just copy and paste-- 2 Pack x Led Strips 3v Bulbs Diodes 32-65 inch Tv Optical Concave Lens Fliter Backlight w/ cable Double-side Tape 10pcs/pack ( aliexpress ). No need trial and error. No need to live with that dark spot, sir.
Interesting is the way you lift the Backside away from the LCD ! Everybody else uses those suction-clamps to lift the LCD off of the back!
repairing led back linght you do good job
mate you’re awesome !👏👏👏👏
The dip replacement leds always need the diffuser lens otherwise they will appear as white spots on the picture.Also you can remove the bad led and solder with wires a small part of led strip with a single led taken from old one.In some cases i have replaced the burnt led with a resistor as a dummy load.There was a very little dark area hard to notice.
George George your are right
Good work bro. Weldone
Thank you very much for this video, I have a new TV again
Changing 1by 1led bulb is good for up to 2months. Next time change all with new backlight so the costumer became satisfy

So nice no1........

Pretty clever but I wonder how it would look if you did all of them like that. I'm sure 1 wouldn't be noticeable at all I'm sure. Probably wouldn't notice it much if you didn't even put the 2 bulbs in there but if you could replace them all that would be amazing if it worked. I have same problem with leds but not sure how many. I know I have to order the led strip but takes so long to get here but I do have some of those so I might just try this out. It's gotta be better then the other solution using a regular diode with a resistor to bypass the led. Either way ingenious idea and now I might be able to get mine working instead of waiting.
my2centz veery ugly indeed, buy a new strip don't waste your time
@@doityourself8314 I ended up waiting on the smd chips and replaced them using a heat gun even though you say it will reduce the life I figured it's so easy and the chips are so cheap. I just wanted to basically see if I could fix it myself. It's been working fine so far although I wish I knew of a glue that would hold the stupid reflectors on other then 2 part epoxy which is what I ended up having to use after taking apart a couple times to reinstall them lol. Superglue isn't so super lol. I don't know why but I tried 5 different name brand super glues and none would work. It's like the lensons kept them from drying or something. Very aggravating lol.
Use clear bathroom silicone sealant. Just a small dab on the end of a needle for each spot then let it set for a few hours before moving. It will hold.
how many volts am i required to right up with individual bulb sir?
Hi what will happen if i remove all my lcd tubes and place leds which is powered from outside source ? Please reply
Good work boro
Very nice brother
Hello bro how many days that dip led worked ? Plz reply. And why you used 2 dip led in parallel instead of useing it in series to maintain 3v
Good morning friend, I have a television that has the same fault, uncover it and I could see that I had a led burned in the bottom line, my question and my problems is the following, when replacing the burned led all turn on individually, I can do so that all the led on the bottom line turn all on
Rodolfo Pirela replace the hall strip
Super boss

Sir aap ne ek wayar se kisme sort kiye hai jo pori led jal rahi tha
Good job
So I took my Samsung 60 JS 7000 apart. It has ten rows but only bottom 6 work and the top 4 rows don’t. I switched out a working one and placed on top and the bad one at bottom. All rows lit up like a Christmas tree. I was happy only to find out that when I picked my tv to check the back the TVs top4 rows turned off again. I kinda wiggled it and they turned on again. The strips all work fine. Do you know what could be causing top 4 rows from turning off? I have no issue with the bottom 6 rows. If you can help or anyone that might has some knowledge of tv electronics it would be greatly appreciated. When this first started I would just give a bang and tv would work fine until it didn’t. Eventually not a bang to tv would work. So my thinking there is a loose wire or something might be triggering or not triggering for the lights to turn. Again any help would be great.
meu migo não se troca leds fazendo este torrão na placa não viuuu, use um soprador térmico ou uma estação de ar quente tirando pela parte de baixo, que você não vai deixar nem vestigio de que o led foi tocado, use uma fita térmica na parte de baixo a onde você vai aquecer para retirar o led, não vai escurecer e vai proteger a régua ok,
fica a dica.
I dont know what i missed. Im repairing my smart tv by my self. The problem is the light reflector and my tv have white spot. After repairing and i switch on the tv, i found out the lcd broken. I dont know where i miss. Im thinking what causing the broken
Did you put or plug back everything in place and order? And make sure you didn't rip off any parts. A better description of your Problem would help to fix it.
Thanks sir
What is use checking tool sir marketing how much rate
Anyone watching the last part he needs to learn to solder and use flux, pair of tweezers and buy a smaller soldering iron flux cleans the board and helps the solder to stick without it you get a mess
I tried same thing when I could not source the correct SMD LEDs, unknown voltage and amps. Mine glowed very dim. My Sharp had 3 diffusers: 1 fesnel lens, 1 opaque and one semi clear along with the LCD glass.

Damn that looks like a hot mess. But I guess if it works and no one will see it.....

It is my belief that it is a waste of time to replace or fix the individual LED's; especially if the LED's have been burning for years. Better to purchase the LED strips and replace the whole lot. These are relative inexpensive on eBay. And VERY easy to replace all of the entire strips.
my sony bravia LED mai kabhi kabhi light automatic bandh ho jati hai... pls give solution
Y a qué hora Quito y puso las placas reflectoras y difusoras y difuminadoras para los que crean que es muy facil. No lo es, solamente con práctica lo pueden hacer, de lo contrario pueden romper el panel de LCD. Y más si son de 42p, 50p o más
what is the average cost of one LED strip
Do you need LCD TV backlight belt?Our manufacturer can provide you with a large number of products.
Hi, how do you fix the little plastic dome on top of the LED? Do you use glue?

Hallo ich habe eine Frage die zum Teil ihr Video betrifft. Und zwar habe ich einen Grundig 55 VLE 9474 der nach ein Paar Minuten oben und unten dunkel wird. Ich habe auch bemerkt das er dunkel wird sobald die Hintergrundbeleuchtung ständig die bildschatten bearbeiten muss das dann dass Bild oben und unten dunkel wird. Wenn ich denn Fernseher direkt nach dem einschalten als pc HDMI Monitor benutze bleibt das Bild stabil aber sobald viel farbwechsel im Bild vor kommt dunkelt er wieder ein. Könten Sie mir vielleicht bei dem Problem weiterhelfen? Ich Frage Sie da ich mit ihr Video anschaute und herausnahm das die Ahnung von der Materie haben.
Und wenn nicht trotzdem Danke!
what ever you put on the led to glue it killed the led
Joseph Melville they also failed but failed shorted

As a rookie I just purchased all new back light strips. Don't wanna risk another one going out again.
How did that work for you? I'm in the same process and ordered a new set of back light strips from China.
@@alexboyraz8257 yea got my leads too from China with high ratings. I already installed them and all I can say is that it was no easy task BUT I enjoy a challenge. Just be very careful on the removal of the lcd. Other than that the TV works great 😁👍

i give up. i will buy new one if this is so troublesome.
