While we always strive to provide accurate and detailed information, we can't guarantee that it will fix your TVs issues. ShopJimmy is not responsible for and damage or harm that you may cause to yourself of TV during the repair process. Try all repairs and troubleshooting at your own risk. Be sure to take all of the proper safety precautions.
In this video we will show the process of how to replace the LEDs in LG TV model numbers that start with 50LN. While all of the models do not use the exact same LEDs, the process should be very similar in these models. This can also be used as a general tutorial showing how to replace LED strips. When replacing LED strips, you will have to remove the panel. Removing the panel can be very difficult, as the panel is extremely . If you damage the panel during the replacement process, you will have to get a new TV.
I will remove the back cover.
Disconnect the two ribbon cables from the T-Con board and the two other wires from the IR sensor.
Disconnect the bezel from the clips and then lift the bezel to remove it. Your T-con board may have a cover over it that will need to be removed before disconnecting the ribbon cables.
Remove the screws that hold the panel brackets in place. After you have removed all of the screws for each bracket, you can remove the bracket.
Slide the scan boards out and temporarily tape them to the panel.
Once again the TV panel is fragile, be sure to be very cautious with the panel to be sure it does not crack or break.
Use two thin pieces of plastic or something similar to get underneath the panel. Be sure not to touch the underside of the panel with your hands. If you do not have thin plastic sheets, you can try using a few sheets of printer paper on each side of the panel to lift and remove it.
Lift it away from the TV and set it aside on a non-abrasive surface.
Undo the clips on all sides holding the filter frame in place.
There are two light filters, tape them together in two of the corners and then lift them from the TV.
Then squeeze the plastic clips on the risers in order to remove them. This TV has 4 of them.
We can now remove the reflector.
Disconnect the small cable on the distributor board and then remove the board.
The LED strips are held in place by double sided tape. Use a 5 in 1 tool or a putty knife to carefully remove the strips from the light case.
After you have removed all of the LED strips, install the replacement distributor board and secure it to the light case with the screws. Also, be sure to connect the cable to the distributor board.
In order to help your replacement LED strips adhere to the light case. It is recommended to use double sided tape on the backside of each of the LED strips.
Connect the LED strip to the distributor board, and then adhere the strip to the light case, then connect the second strip for that row.
Be sure to use the correct strips in the correct places. These strips are labeled as R1, L1, R2 and L2. The R1 connects on the top strip to the distributor board, and then connect L1 to that strip and then R2 and L2 below that. There may also be labels on the light case as well to help guide you.
It is recommended to test the LEDs before re-assembling the TV.
Reinstall the reflector and 4 riser clips to hold it in place.
Put the light filters back in place and remove the tape securing them together.
Reinstall the filter frame.
Now, reinstall the panel.
Next, put the 4 panel brackets back in place and secure them with the screws.
Before installing this panel bracket, remove the tape holding the scan board to the panel, and slide them back into place.
Now, we can reinstall the bezel.
Reconnect the two wires from the IR sensor and two ribbon cables from the t-con board.
Check that all of the connectors are secure before placing the back cover on the TV.
There you have it, we have shown how to replace the LEDs in this LG TV.

This video saved my tv that was 7 years old! This would have taken so much longer without the parts and video from ShopJimmy! Thank you!

[@SeyedehFatemehHosseini-kw9sl]

Perfect video! We repair our TV with this tutorial and it is working very well! Thank you so much!!!!

[@macsenviehweg]

Great tutorial and great product from ShopJimmy. Bought this broken tv off Craigslist for $40. Parts and shipping for 12 new LED strips and double sided tape was $80. So all in this $600 TV only cost me $120. SCORE!!

[@topnotchhomie]

Macsen Viehweg thanks for the review.

[@wilsonashton4134]

Great video! I just finished fixing my TV using this video. It was very descriptive and useful! Thanks!

[@miketobin8834]

Amazing tutorial, my TV is up and running again! Thank you Shop Jimmy!!!

[@jrobersoniii]

Just changed out my LED strips following this tutorial (along with other trouble-shooting ones) and the TV works fine now!

[@11PalmsKovach]

Thanks!! I was able to use your video to do the replacements. Excellent job!

[@rutgers789]

Awesome video! This helped me get new LED strips and repair my 3 year tv! Thanks!

[@Prophet78X]

Thank you for this great video. I followed it and I have successfully repaired my 47" LG TV.

[@tinydemons988]

I would like to thank you very much for this... I ordered the light kit and it took I little longer than I thought because of a few problems with the tv stand. I followed your video and it was great. this saved me all kinds of money... I called vizio and they said that my TV's warranty ended in june of this year and tried to talk me into another tv... I saw your video and now the vizio is like new thanks

[@mannynieves6533]

great video, step by step instructions on how to replace LED strips for LG TVs , done in about an hour , and I'm not a electronic technician and this video help me to fix my 42" LG TV. When I call LG company they said it is a out of warranty and is going to cost me over $300 that's only the repair with out parts. Thanks to ShopJimmy.com and there support I found the LEDs strips for less than $70.00 to fix my TV.

[@JoshuaHenslee]

Awesome video. Just used this to replace LEDs in my 10 year old LG tv.

[@user-pb8nt8nm6b]

Thank you, this great video. I have repaired my 50 inch led TV. And I am very proud that I fixed my tv by myself.

[@jermonken]

Competent tutorial. Great job!

[@mikemacburney2227]

Just replaced the entire LED strip set in my 5 year old 47" LG with ShopJimmy's product. This video and the product made everything go great. It works perfectly now. Since only one LED was burned, I'll save the rest of the old strips for any future problems, but I'm guessing these new ones will probably last 5 years, too. (Who knows what TVs will be like in 5 years). 5 stars for ShopJimmy! BTW, the new strips already had self adhesive on them with peel paper strips.

[@MWhite-dv1uu]

Still working?

[@lucasjuanmejia9042]

I was able to fix my 32" LG TV following your instructions and your parts! Thank you so much!

[@atanuknath]

Was your tv blinking or had no backlight at all.. My 32 inch has blinking backlight.. so thinking if changing strips would help..

[@GimliTehDwarf]

This worked amazing! Tv is good to go! Thanks Shop jimmy. Want to make a review on the site as well

[@Patch1stripeTVParts]

Great video! Thank you.

[@absurdangst]

Great walk through (Toshiba 50l 1350U). My tv had 4 plastic risers as described, but two with a straight tip and two curved tip. I didn't see how they came out, couldn't find any reference, so I just guessed when they went back in. *** Take the warning about the panel being thin and fragile to heart, especially when putting it back in because it needs to be very tightly aligned. Don't force it (like me, 3 inch crack in the upper left corner, but barely noticable :) ****

[@chriso8193]

The vid is 16:52, except for speeding up a bit, this can be done in less than an hour??? I'm picking up a 50" of this model tomorrow for $30 cash (no backlight), going to link to buy strips and I'll get back and let you know if I did it right....

[@CommodoreFistyCups]

a neighbor gave a tv that he was throwing away because the tv was black. i saw your tutorial on the flaslight test and it worked, i have sound and when i run a flash light thru i can see an image. he said he had this problem before and he someone replace the backlight, my question is should i replace the backlight or the inverter according to your tutorial? thanks in advance

[@eusebioayala421]

I worked on the same model and it worked! However the picture seems a bit skippy like lines r in the way but it lines up then it goes back to it ??

[@camerondary]

Thanks for making this process so easy to follow. I replaced the light strips and the backlight is now clearly working. The issue now is I can't get anything to show on the screen, no inputs, no menu, nothing. Is there a chance I reconnected the ribbons or something else wrong and that's causing the issue, or is something else wrong with my tv?

[@swlhonda1]

Does the thickest diffuser go down first?

[@currentuserjade]

Thanks for the informative vid. I used your tutorial to replace a single strip about a year ago, now I've had two other strips with defective leds. I just purchased a full set from your eBay store, and hope to get a few more years out of this tv. It'll be nice to have the older ones that are still good laying around too. Question, I understand that you say to update to latest version of software. If I already have the latest, is it best just to re-initialize the set to factory settings, and then lower the brightness and backlight settings? Thanks again for the info AND the led's. Oh, and this time, I'll tape the screens, lol....what a pain to line up, but it was successful. G2G, these dark spots are messin' with me eyes........

[@devkamdi9451]

what is the nail glue.can i use simple glue or normal glue.pls reply as soon as possible.

[@asuhdaddude]

So if I damaged a ribbon cable between the scanboard and the panel, can I get a new scanboard?

[@stevenmurray547]

Great video. Is there a process to clean the LCD panel if you touch it?

[@nunyabidness117]

Spray the cloth, then wipe the screen. Do not spray directly on screen as it can run down and short the electronics.

[@haba136]

Diretoe bem explicativo!!

[@dstric]

Hey thanks fixed my tv

[@019208237]

I thought leds were supposed to last years and yet this is such a common issue. We are in 2018 surely they can use better more reliable technology. Imo it all comes down to greed in the end. They want us to keep buying new TVs.

[@chris532008]

Support the new world order. It Leger worse

[@zacharylord6472]

I didnt get a new distributor board in my order, can I still use my old one

[@nunyabidness117]

Hi...I replaced my LEDs. The screen now lights up and I get sound but no image. Any ideas?

[@CommodoreFistyCups]

a neighbor gave a tv that he was throwing away because the tv was black. i saw your tutorial on the flaslight test and it worked, i have sound and when i run a flash light thru i can see an image. he said he had this problem before and he someone replace the backlight, my question is should i replace the backlight or the inverter according to your tutorial? also my model tv is lg 50ln5100 thanks in advance

[@BeastoNinjaGaming]

hey i have the same tv and the same issue, did you ever get yours working? if so what was the issue if i may ask?

[@billregan3232]

Thanks for video. One question: how are the LEDs tested before reassembling the TV. This was mentioned but not explained. Thanks again.

[@CognacKidd]

There is probably a cheaper way but shopjimmy sells an LED tester that you can buy and use before you re-assemble the TV...

[@chris532008]

Best do sometimes it s not the led but printed circuit itself

[@davidnicol8629]

You connect 3 nine volt battery to make a tester they connect positives to negative etc..the open terminals add speaker wire or electrical wire and you now have power to LEDs.. however Google more on home made LEDs testers

[@heatherplauche4781]

I have a insignia ns-48d510na15. the tv's backlight comes on but there's no picture. when I turn the tv on there's a red light that blinks 5-6 times. I replaced the main board, but that did not fix the issue. the next I am thinking needs replacing is either the t-con board or the power board. any help would be appreciated

[@WizardsMagic007]

Have you checked the ceramic fuse on the t-con board?

[@mokaafat6485]

Hello dear sirs. I have LED Samsung model UA32F5550AM that I receive sound but i dont have light and back-light. Now my question is how i can understand that LEDs are damaged without opening panel and access to LEDs or driver of moderates?Thank you so much. sincerely yous

[@topnotchhomie]

mokaa fat your whole problem is your leds you need them replaced no matter what.

[@rwerner43]

A question for you. I have a 47" LG tv that started flashing. On, off, on, off. Sound is fine and picture seems OK when it flashes. I have replaced all three boards on the back. One post indicated that maybe some LED's have gone bad causing the ballast to reset. Would you agree? If so would you replace all LED's or try to figure out which are bad. Thanks

[@topnotchhomie]

ricor43 i have same problem

[@johnnyteres]

Had the same problem here. It's a series of burnt out LEDs. You can replace one or two and see if it turns back on but the best method is to replace them all. If they are the original LEDs, they'll continue to burn out one by one until the TV turns off again.

[@JaseCJay]

@@johnnyteres im in the process! All new led banks!

[@maheshkalokhe5724]

Can i use super glue to stick cap over led in led tv?

[@currentuserjade]

Most people do so. If the same led burns out, it'd be best to replace the strip anyway, so the need for a removable adhesive isn't necessary. At least that's my opinion. Be sure to only use superglue in the 3 dark spots made for adhesive, and not on the led itself. Btw, ShopJimmy sells the unit to heat the strip for led removal, in case you didn't know.

[@kiki1965]

So because I'm not that technical, how much should I expect to pay for a tv repair person to repair/replace these LED's? I live here in Bronx, NY. Thanks.

[@ihabomari1345]

About 200 dollars!

[@davidnicol8629]

@@ihabomari1345 my 55 inch lg in Canada all 4 quotes 300 to 360...I bought the full backlights for 60 bucks ..so I'm gonna try this myself..if it fails I buy a new TV sell this for parts..55LGLA6205 2013...

[@scottmiller8941]

I am just trying to match up the part number for LED light strips with my TV. I called the 877 number and the guy would not directly help me. He said I needed to go to You tube and watch "the" video. So, I have watched several and cannot figure out which light strip I need for my LG LED 55LB6100. The guy on the phone said I need to match up what's on my "board". Well, I have 3-4 boards. On each one, are several numbers. Please help me with this. Will this light strip: part no.sj-NC500DUN-VXBP2 work on my TV?

[@davidnicol8629]

I think the replacements for 55 inch LG are all the same .I ordered from Ebay getting think in a week or so.60 bucks.they have lost my TV is lg55la6205

[@PcruProducer]

i have an LG that has this issue. i replaced everything but this. it gives me a flash and the. shuts off. is there a way to test these lights?

[@fabulousfabricationsimmacu4962]

Do what he did you have maybe just one burned out led !

[@fabulousfabricationsimmacu4962]

Is L1 led strip the same as L2 led strip?

[@bmusser4psu]

no

[@bengus8148]

I can't believe you didn't have a half a dozen of those reflectors that have fallen off--very common problem with LG TV's.

[@elcooko4372]

How can I tell which led strips need replaced?

[@JaseCJay]

Stripped down to the led banks/back plate with the boards installed, the bad led or led bank will flicker while the rest stay dark? I'm about to find out myself on a 240Hz 50" LG... or get electrocuted!

[@JaseCJay]

4:05 what - can happen/do you do, if you touch the underside of the panel.. fk

[@davebenham4933]

DONT DO IT Takes 3 hrs of tedious concentration, so many steps that you can make mistake then when all done and said the frame did not align and our screen cracked but before that the scanning strips would not align and go back in and properly show full image. We spent 167.00 on bulbs, tools and all the stuff and as a highly experienced mr fixer just go buy another tv. Now we have a LG 50 w new bulbs and its worthless except we spent more to make sure its worthless.

[@Iahusha777Iahuah]

LEDS are suppose to last a long time, they must not be of the best quality, I wonder if I can turn on tv and see which light is out so I can replace only one 12 $ strip rather then all of them for 72$ I really dont care

[@rlewis9608254]

they have testers you can buy to see which ones are bad.
