- As this TV is basically only about 5 years old and in excellent condition (except for being unwatchable due to flashing LED backlights!), I thought it was worth trying to fix the problem and save this nice TV from the waste-stream..
It's a 50" LG smart TV model 50LB5820, but I believe the process is pretty much the same for many models. Also, something interesting I discovered was that the default setting for the LED brightness is 100% - and this can lead to them burning out prematurely. A quick online search shows that this appears to be a fairly common LG problem which for many people means the death of their expensive TV. Turning down the LED brightness is an easy process through the menu (settings) button on the remote and you should then protect your TV from an early demise! 😊

Just an update on this TV - it has now been two years since this repair and it has become our main living room TV, used everyday for quite a few hours typically. I have the backlight intensity set to about 60%. It is still performing perfectly! 😊😊
Those back lights will last a very very long time at 60 % ......
Thank you here at home they think everything is easy your video will show them the reality 1:50 thats what Im getting
I've had this same tv for probably 10 years now and it just started doing the same thing. The repair looks easy enough, thanks for sharing.
Good luck BS. It's time consuming but pretty straight forward 👍 Remember to check the LED backlight intensity setting when you are going again - they shouldn't be set at 100%
Your shop looks very neat & tidy just as it was in this video - the carpet will be a plus for sure, comfort wise.
This video was filmed at home in my workshop - not at the shop. Both places are way more cluttered these days! 🤣🤣
You're amazing. I wish I had the nowse to be this resourceful and effectual.
It's a matter of research and determination Tomás! Thanks for your comment 😊
Seriously you have the patience of a saint brother .. I have much respect for you .. thank you for tour videos.. I’ve scrapped a lot of those with I would of saved those led stripes then I could of sent those to ya plus the jar of screws I’ve been saving for ya because I would love to see that jar on your self at your shop .. 👊🏻
Haha, thanks Seth! It's not gonna be economical to send me a jar of screws but I love it that you thought of it! 💗👍😁
The Ultimate Recycler it with be worth it just to see and then you can laugh when you sell it .. and go buy your self a beer 👊🏻
Just incredible! Thank you. Good save!
Thanks Marcia - it's very satisfying saving these things! 😊
The LED diodes are 3535 6V with larger cathode (-) and smaller anode (+). Could be 1W or 2W, can't say.
Thanks for the info mate 😊
What a great save mate, not bad for a few hours and 50 bux.
Thanks Mitchell - it's now our main TV at home! Sold the old one and this one is great! 👍😊
Would have been nice if you had shown installing a row. Is it better to put the A side down first then connect the b... or to connect them then lay them down???
Sorry Kevin! This was over 3 years ago - I was still working out what to film or not! I think I placed the strips down and then connected them afterwards. Thanks for watching 😊👍
I’m still watching the video but I couldn’t wait to write you
Haha, I thought you must have watched it on 2x speed!! 🤣
The Ultimate Recycler no sir I watch till the end my friend
What is the part number for the LED lights?
I don't remember puternash, but all I did was to search ebay for the TV model number and found the suitable backlights 👍
Following your video to the T, I am stuck at the part where you took the mainframe off while leaving the LCD on the towel. I have the small screws on the side removed, but I think you mentioned something about clips getting attached/reattached, do you remember how you got the darn mainframe off to the red makeshift table?
Sorry I'm a bit late with this reply! Hope you managed to work it out.. yeah, little plastic clips all the way around the housing from memory.
Insert some thin cards between the metal and plastic clips. Like playing cards or old bank cards. Then lift the chassis out of the frame one corner at a time. 2 persons are recommended fir this part.
@@Simion_T Thanks for that - good advice! 👍😊
Anyone know where I can buy new led strips for LG 50LB5800 2014 ASAP please
Did you try ebay Thomas?
@@TheUltimateRecycler no I haven’t yet need a link not good at finding stuff on the net.
I have just bought tv lg uhd 65 AI thinq inch when opened the box there was a crack in the screen can it be repaired
Unfortunately a cracked screen cannot be repaired 😟
It's e-waste day. I paraded the line with the car idling for an hour for our free drop off. Got rid of 3 totes of boards. Didn't (couldn't) have to get out of the car as friendly men in safety vests took stuff. It hurt to see all the flat screens heaped into skid sized boxes. Hurry hurry keep the line moving. Never been any picking allowed as insurance liability kills all recycling efforts. So sad! The curb is the only place to pick these screens up. By then they are always cracked though they make great daylight "skylight" panels.
It is such a shame that liability issues put an end to so much easy repair work (and sometimes no fixing is even required!). Too much goes to landfill unnecessarily!!
Great job 👊🏻
Thanks mate! It's now our main TV (the other wasn't a smart one!). Working beautifully! 😊
The Ultimate Recycler there’s no doubt in my mind that is works great 👊🏻
$500 retail, $1 scrap. Something wrong there!
There's virtually no scrap value in these things unfortunately!
Could you give me the link for the led in China my tv is all I got to pass time and cannot afford anew tv thks
Just search the TV model number on ebay Thomas - that's how I found mine..
I have just been gifted the exact same TV with the same fault. My plan is to replace only the faultyLEDs . I am also close to Melbourne. I think it’s a common fault with this model. My plan is go to Jaycar today.
Good luck with it mate! Yes, just replacing the faulty LEDs should work 👍 Remember to check the LED brightness in the TV settings once you are done - If they are at 100%, they are indeed prone to burning out! This TV is our main loungeroom unit now and still working perfectly after almost 6 months daily use. I think I have the LEDs at about 70%. Let me know how you go! 😊
@@TheUltimateRecycler This one is for my father-in-law. Did you know that this TV is a 3D 100 hz
@@vk3tkq589 Nope, I didn't know that!
Hi, do you have a link / name to the place in CHina that you bought the backlight strips from please?
I just bought them on ebay! I searched the TV model number for backlight LED strips and found a seller straight away!
Please put the link of where you bought the strips in China
I just searched ebay for the TV model number and "backlight"

Nice sir thanks for sharing New subscriber here Shout out
Thanks, glad you found it interesting 👍🙂
My 65 inch 3D LG TV having edge leaking light and right hand top corner having black shadow due to led back light dead, the LG service technician told me need to order a new 65 inch screen to replace it which is difficult to find. And my screen some times have blinking problem when the screen turns black still has sound,due to power voltage control part malfunction. So bad the LG quality! LG life is garbage!
Yep, I've heard a few technicians say bad things about LG quality!
@@TheUltimateRecycler my panasonic viera used for decades , still no light leaking and black shadow plus blinking!
How much charge to repair it
I don't do repairs for other people jainik..
