Try all repairs and troubleshooting at your own risk.
In this video we will show how to replace the LED strips in certain LG TVs.
This is a generic tutorial, and if your TV model is listed in the video description, the general process shown in this video should apply to your TV, even if there are some small differences.
When replacing LED strips, you will have to remove the panel.
Removing the panel can be very difficult. If your TV panel is damaged during the replacement process, you will have to get a replacement TV.
Start by removing the screws and the back cover off the TV.
Disconnect the cables to the speakers and set the speakers aside.
Disconnect the cables to the t-con board and to the scan drive boards. Remove the screws and the plastic cover over the t-con.
Remove the screws on the metal covers that are over the scan drive boards.
Remove the screws for the TV bezel.
Adjust the tabs and remove the metal covers.
Release the scan drive boards.
When releasing the scan drive boards, disconnect the ribbon cables on the scan drive board. These cables are the ones that connect from the scan drive board to the t-con board.
Remove the remaining bezel screws.
Flip the TV over and remove the bezel.
Flip up the scan drive boards and tape them to the TV panel.
Release the tabs and tape on the side of the panel to release it from the chassis.
Release the tabs on the filter frame and remove it from the chassis.
Tape the corners of the light filters before removing them, to keep them in order and together.
Lift and remove the light filters.
Pinch the reflector clips to remove them from the panel.
Remove the clips on the front side of the chassis.
You will need to push them to the side and then lift to remove them.
Remove the reflector sheet.
Take pictures of the original LED strips to help when reinstalling the replacements.
You will want pictures of the strips connected to the cables in the order that they go in.
Disconnect the cables from the LED strips.
Using a five in one tool, or something similar, remove the LED strips.
It may help to use a five in one tool and something to push the tool from the back.
Install the replacement LED strips. They may be sticky on one side, but we will use some double sided tape, just to be sure they adhere to the chassis.
It may happen that an LED lens gets knocked off when installing the LED strips. If this happens, and you need to use that strip, you can use super glue or hot glue to put the lens back in place.
Install the replacement LED strips and reconnect them to the cables. Be sure they are properly aligned.
Install the reflector and begin installing the clips.
Reinstall the light filters and remove the tape.
Reinstall the filter frame.
Reinstall the panel.
Reconnect the tabs and tape on the sides of the panel.
Release the scan drive boards.
Reinstall the bezel.
Align the scan drive boards and the tabs and reinstall the metal covers.
Install the screws for the metal covers and bezel.
Reinstall the plastic t-con cover and reconnect the ribbon cable to the main board.
Reconnect the speakers.
Reinstall the back cover.

Just repaired my 61” LG following your video and saved a $1000 TV for $60 for LED strips off of eBay! Thanks for the video!!

[gabbyprod]

Great tutorial! Fixed my LG $1, 500 for $24 in an hour.
1 down, 2 to go.
Thank you!

My TV started to flicker on and off the other morning. After dealing with LG Support, I got on YouTube to see if I could figure out my problem. I came upon this video and decided I would give it a shot. When I received my new LEDs, I noticed the + and – markings on the new ones were different than the markings on mine. I contacted Shop Jimmy to inquire about the difference as I did not want to fry my TV. Shop Jimmy assured me the strips were correct and that the plugs would need a little extra pressure to install them on to the new strips. I proceeded with the install and my TV now works like a brand new one. Thanks Shop Jimmy for your product, video, and your professional support team. FYI my TV was a LG model 60LB6500-UP.

As a person who has already done this you don't need to do half the stuff this guy is doing. 1. No need to buy suction cups, place screen face down on a towel let it rest there instead of trying to lift screen. 2. No need to hammer and chisel the strips off they just pull off if you do it with care keeping your hand close to where you pull. 3. Unless all of your strips / LED's are burnt out i wouldn't be replacing the entire strip(s). They are quite expensive to buy and you are not guaranteed they are new, and if second hand you don't know how many hours are on them. The cheapest way is to buy individual LED's from Ebay or Amazon costing cents and replacing them. They are easy enough to replace with a soldering iron. I have done this on exact LG in video and replaced 8 burnt LED's, Job done.

I was given a 55" LG with the picture flashing on and off. Dismantled it per your video and found 36 of 55 of the backlight LEDs burned out. Replaced all the strips with new ones from Shop Jimmy and now I have an "almost free" 55" TV. Set the backlight to 73% to hopefully prevent future burnouts! Thanks for your concise videos and great parts selection!

I just fixed my 55" LG with this tutorial, just cost me 20 euros! Thank you!! Took a few hours, because did not want to break anything 😅 but it was well worth it!

[alialshabeeb]

Today I finally fixed my tv according to this video and I become very happy. I just want to say thank you very much from bottom of my heart.

[OvervoltedMinds]

This was super helpful! Just finished repairing a 49” one. It wasn’t exactly like the one in the video, but pretty much there. Took me a couple of hours but not too complicated. Patience and care is all you need.

[robbiewilson]

Great video. I had 2 tables set up with blankets though and flipped the lcd face down on the blanket after i got all the circuit boards loose and lifted the backlight assembly off since i didnt have sx cups. AND it seemed likely for me to break something lifting it and flopping it around. replaced the leds on table 2 and flipped it back.

This video is amazing, I am a young female and I fixed my own tv thanks. I am so proud of myself

I just repaired my LG 55" by using this site and this video. Thanks!
Symptoms - noticed dark spot fluctuating in intensity in top right of tv. This happened for a few days until the tv started to turn off and on in a continuous loop. I decided to replace all of the LED's because this is what I noticed FIRST before the power cycling and because this is a known issue with this LG model, according to various internet search results.
I watched the entire video first. Then, I followed the video step by step, pausing before proceeding to the next step.
The wire connectors/jumpers did not have the same fit as on the original LED strips. I used a standard screwdriver to GENTLY but forcibly push the connector into place on the new led strips.
Suggestions: Watch your fingers when removing the back of the TV, mine has extremely SHARP edges in places and will slice into your fingers. Get the suction cups and the tape. Make sure you have PLENTY of room. Use a blanket for protecting the screen/table (not a thick quilt). If you are able to work on a table, this will save your back and your knees. Wash your hands before touching the filters. Get a few small containers to hold the screws and fasteners. The filter bezel clips were delicate on my tv. I broke 1 because I hulked out, be careful with these. I replaced the strips 1 entire row at a time. I think all but 3 lenses popped off the old strips while removing them so I don't recommend doing this with small children or animals around due to possible choke hazard, make sure you account for each one if you do have children or pets. The old lenses look like they could be used for some artsy fartsy craft project so give them to your grandma or some old person ;)

This was incredibly thorough and extremely helpful. I am very thankful for finding this video. Thank you for showing us how to fix our tvs ourselves instead of overpaying and relying on others.

[jasonglick]

Amazing! I bought an LG 65JU6300 with blue screen for $75. This tutorial helped so much, it's like new. Thank you.

[PenguinQueen]

I was about to buy a new tv before I found this video. Thank you for sharing this. It was super helpful. Really easy to follow and note my tv is working like new and the only cost was $45 on amazon for the parts.

[jasongarcia]

Thanks! Just fixed my old LG. It took about two hours for me, but worth it.

[es]

Just used this to repair my 55LB6000, this video was perfect. Really easy repair overall, just needed to be careful with the LCD panel. Thanks a ton!

[dalehawke]

So glad I found this video, as I am attempting to replace the LEDs on my LG 55lb650v tv this Friday, excited to try doing this myself, but also nervous, but if I'm able to do it myself, then I'll save myself a lot of money in the future if my TV's go wrong .

I have applied every step here, with great care (as much as I could) I have taken the risk of removing the LCD panel which is the most expnsive and fragile part in the assembly. It's not very easy to remove every connector as well, especially the panel driver connector is very sensitive too. There are so many screws and all sorts of clips and one must be very careful to remove them without damagnig the TV. I have used a smaller set of vacuums to hold the LCD but they did the job (still paying great attention while holding the LCD panel)... Hint: this LG model of mine, claims that its LCD is immune to mechanical crashes, so I was hoping that bending during panel removal won't cause a problem... So many levels, very tiring, it took about 4 hours for me. (one hour for just one defective screw!) At the end of the day, I have managed to replace one line of leds which was defective... Thank you sir for this extremely helpful guide. ..

*UPDATE:* four months ago I have replaced one row of 2 LED bars (A and B type), and commented the result. Now, last month another LED strip from the remaining bars also burnt... :-(. This was expected, but not so soon, the time was somewhat shortened due to the Corona virus stay-home full time TV netflix watching... :-) So, this time I decided to replace the whole set of 10 bars. Last week I bought 5 rows (10 bars) of new LEDs. Reopened the TV and replaced all the bars. One thing I observed was that the defective bar was connected to the renewed bar. Note that among 5 rows, upper two were connected in series and the lower three were connected separately in series. So the new and old bar connection in the upper part failed before the lower three older bars. This supports the fact that renewing just one bar (or one led) among older ones, impose more strain on the remaning bars and kill them faster than otherwise. So it's better to replace them all together unless something else was necesary. It was extremely tiring again. The internal frame that holds white polarizor screening really was a headache. Also moving the LCD panel was a thrill too. Indeed one of the vacuum cups broke during the panel removal but I was lucky as the drop height was less than half a foot. But then I had to find another (safer) approach to remove the LCD screen, not relying on suction cups. Slightly pull the LCD panel aside without scratching and bending it. Note that this model of LG TV claims to have a scratch and hit immune LCD coating. It was demonstrated to me when I decided to buy it. The seller hit the screen with his palm and said that this IPS panel was strong enough to survive children filled house accidents! Anyway. At the end of the day I managed it. But there was a disaster ! In the first trial I have forgotten to connect one cable on the last LED bar! The TV didn't work OMG !!! I almost gone crazy!! but then I re-opened the TV and found that I forgot to connect the LED bar connector at the lowest bar !!! OMG I was happy but very tired! You know. I do not suggest this LG TV. It's overall a good TV but first its LED lighting strategy is wrong which burns then at 4 to 5 years! Furthermore, the white-screen is not fully uniform in brightness and there are ghost shadows on the screen when a white background shows up, especially when it moves fast enough the gost shadow pattern becomes painly visible. I do not suggest this TV because of this. But the functionality of the TV is quite good. It connects very well with computers, ADSL box and other devices. Its built in satellite decoder is also working fine, despite being slow in channel seek...

Thank you ShopJimmy! I just reconnected my LG47LB5800 and it works again! [40+ SBF] I ordered the LED strips and double sided tape from ShopJimmy. The suction cups and 5-in-1 tool were out of stock, got those from Amazon.

One additional suggestions take a photo of how the wires are connected as well as the proper order for the strips. Also use a lightweight tape to keep the filters together.
