- I took some of the strips of LED baqcklights from a broken Samsung TV and turned them into some very bright cabinet lights.
Each strip originally required 48 volts. I make them run on 12.

From a random search, this turned out to be exactly what I needed to see! Thank you! Your video title is accurate and the casual information is invaluable. Cheers!
SAME!
This is a good bit of information that you provided in this video. The LEDs of dead tv's is something that is a piece of a goal of mine. There are other pieces of tv's that I am working on upcycling. Completely free art supplies inside a tv....
I fixed my strip but now they no longer sticker and falling off TV what tape should I use to stick them back on
@@us3309 I found out you have to use thermal double sided tape
Very interesting there! Currently troubleshooting my first given-to-me-free-TV. A Samsung UN48J5000. After disassembly, I found a badly-burned spot between two LEDs that would arc, causing the PS to cycle on & off. I attempted a repair by scraping off the white coating and soldering a wire across the burned-out area. Sort of worked. Kept arcing. Burned out the single LED to the right of the burned area. LED ~ 1.4mm/side. Way too tiny to 'replace'. So I figured I'd just cut the end of the strip off with the burned area + dead LED, scrap off the white coating and complete the series ckt with solder. The rest of the LED's all light. Maybe then the PS would stabilize and stay on. PSB is L48MSF_FDY BN44-00852A. LED light strips are 2015 SVS48 FCOM FHD DOE A RIGHT REV1.2 150605 LM41-00120Q_LM4100149A.
I just bought a flat screen TV home from garbage that had a broken screen didn't realize it was an LED TV wanted to take it apart for the heat sinks inside like another one that I want to use for a project. Instead, I found all these LED's 7 in a row. Like you have their 10 rows, 70 LED's now I've learned how to power them up, and there was no large heat sinks in this TV.
I just scraped a small tv with them lights i keep them cause i thought I could use them ty for input
That intro just kicked me right back to the 90s 😅
Sorry to be so offtopic but does someone know of a tool to get back into an Instagram account?
I stupidly forgot my login password. I would love any assistance you can give me
@Jack Rayan Instablaster =)
@Jon Uriah Thanks for your reply. I got to the site through google and I'm trying it out atm.
Looks like it's gonna take a while so I will get back to you later with my results.
@Jon Uriah it worked and I finally got access to my account again. I am so happy:D
Thanks so much, you saved my account :D
@Jack Rayan No problem :)
any way to find out what CRI (color rendering index) any LED backlight TV has? are they generally high CRI?
You would probably have to look at the specifications for each set; there are simply too many models to narrow down.
OMG, you're GENIUS!! I picked up a giant 72" screen dumped on the street, and want to light it up. Now all I need is just a power supply!
from lop top power supply you can make the strip light up. ( 16 vdc ) or 32 vdc for all strip with 1.5 amp. work fine i use one under my microwave and work fine.if you use just 1/2 strip use a jumper and the end.
why not do the + and - connections directly where is the faulty led by eliminating it?
LEDS always a subject of interest, just made my own 12 volt strip light on discarded keyboard sensor contact PCB skeleton base - used online led array designer wizard tool - ended up with 24 blue LEDs 12 x 220 ohmn resistors , each 3 mm blue led running about 3.5 volts 23 mili amps.
Excuse my ignorance, but when you tested the 3 leds at 2:13 in the video, is your 12v adapter plugged in??
perhaps there will be heat problems, the backside is glued to a metal surface in the TV so they are probably specced to not be stuck to a heatsink.
I have a 94v strip, each led has 3 LEDs in it... it's something like 28 LEDs per strip. 28*3.5 is about 94v perhaps that's the way it's wired.
Use a small computer fan it will keep them from overheating.,😎
The lights still working? never saw them installed, had same idea, wasn't sure how to do it this way, wondering if it was worth it? and how to all cabinets on 1 supply
I appreciate the video my brother kept throwing away the leds thinking they were broken after removal neither of us knew it was just because they were 24V. Now we can wire them up with the correct power supply 😂 👍
I scrapped a 43" and it had 5 strips of 10. I think I measured 27v per strip. What amps do these strips draw?
I hooked mine up to a power supply with a display for the amperage to check the it.
The 12 Volts is correct for (4) 3V LEDs, but how do you limit the current to the nominal 20 mA?
I don't. 3 volts x 4 led is 12 volts. Not worried about current draw they draw what they draw. This is under shelf lighting now and work great. Popped the lens off
Nice illustration. I happen to have the old/original set of led lights from my Samsung 55" TV. Some are blown but a majority are good. Since I am in the process of building an "airbrush painting booth" (64qt bin), I want to add these leds along the top. I will have to review your video, so as to pin point where you scratched the paint off and where to solder wires.
I'd like to know if that black box was a laptop power supply? You said 12v..? I kinda thought these leds needed about 27v to light up. Do you have a way to hook my idea up?
I got shloads of these things, was wondering what to do w/ 'em....excellent ;)
I did this years ago. You can cut a strip 2cm wide for each LED. There are seven LEDs in those strips so you cant split them in two!!
Just salved some from a Vizio tv, are they the same voltage? Nice work, love the clock.
How do you recycle the LCD screen? Thank you
I would take the liquid cyistal screens to Best buy for recycle.. but if you wanna be creative... Try adding current the the LCD watch how it turns opaque..
I came across a broken TV in an alley that I took apart on the spot just to see what was inside and it had these kind. I didn’t keep them in a strip through and cut them into pieces with the +&- still showing. Since then I have taken apart a 65” TV, a 24” computer flat screen, and a laptop monitor and those 3 had LED strips but they were all surface mounted flat LEDs about 1/4” apart from eachother and not spaced out in a little clear bubble. And I kept them in a strip. They are incredibly bright. Infact they are bright enough to blind me temporarily. I’ve only lit them up with 2 AA batteries since I think most white LEDs are 3v.
Man you help me a lot much much appreciate 👏👏
Cool idea!
Hi..i have very similar strip that required 20V so i tried to connect it to my 18V 500mA drill charger and it worked but i need that charger so I get the laptop charger with 20V 2.5A output and strip wont light up..could higher amps be a problem??
Many of those modern laptop chargers actually communicate over the power cord to the laptop to see if it is the correct make / model and if not they will not charge or put out any voltage.
My HP work computer will not charge on my DELL adapter even thought they are both rated the same, nor will my Dell laptop charge on my work computer power supply. For that matter it also will not charge the battery from my old Dell power supply, but that one will run the newer dell, just not charge the battery unless the computer is totally powered down and then the adapter connected. In that case it will charge, but as soon as the laptop is booted a message comes up on t he screen saying that the adapter is not the correct model and will not charge the battery. Both are 19V 4A chargers, but the older one doesn't have the chip that communicates with the laptop. Sony was good at pulling that crap with their camcorder batteries so if you bought a new camcorder the old batteries would not work with it.
@@12voltvids ooo yea..you are right ..not good power source for me then 😒
I have some? AG-D1 94v-0 1336, how can i get these to light up. AC or DC?. I want to use them on my train layout
I have 9 lights on my strip and it is labeled 94 V . So I could only run 1 light with 10 Volt ? Would that be correct?
9 lights would be more like 24 vikts. They are in series and need about 3 volts each.
Fun video. I just tore a 42" TV down. All the strips had one or more damaged LED's. I repaired them with 5mm bright white LED's and am planing on making a light for my camera. It is so much fun re purposing things.
I used these to light up a stereo cabinet.
Would it be feasible to use one of these LEDs for a flashlight powered by an 18650 cell?
Yes,but youlll need a resister probably.
Do they still run as bright as they would have on a 24v feed? If so, I don’t get why they’d set these up with 24v instead of running a 12v up the middle or just manufacturing the strips in half sections.. but if NOT, then I get why they’d use 24v...
I’m just asking because I have tons of these and tons of the screen films just waiting for DIY projects but the bulb strips always scared me ever since I tried to just leave them in place and plug the TV’s wire right in.... I got a spark and magic smoke 💨 which confuses me because other videos and people I’ve read in blogs do this with no issue... so I’m trying to learn and understand. Thanks
They run 24 / 48 / 96 volts per strip because the higher the voltage the lower the current and the smaller wires they can use to feed them.
Got a big van and 2 TVs worth. One set of 4 and another set of 11. So, 4 for the overhead, and the 11 separate for the tool shelf/rack
As LEDs are connected in series, if you abandon one or two coz they are faulty with out replacing them, don't you think that there is an increase in supply voltage of LEDs remaining on the strip ,compared to their rated voltage, hence affecting their performance?
Not at all. The power supply is current regulated not voltage. It adjusts the voltage dynamically depending on the series load. Remove 1 or 2 and the voltage drops. I have seen panels with 20 shorted led and they rest are still running. Remember led fail in 2 ways. They short or go open. When they short you get a slight dimming of the panel at that area. The one I did a full backlight replace on last year had a bunch shorted when one went open and took the panel out.
Wouldn't just soldering leads to the center solve the 24v issue? Instead of cutting the trace?
All the LEDs are in series requiring 24v. They need to be cut so they can be wired as 2 12 strings in parallel.
I knew my instincts to keep these things was right
hello good vid yesterday i bourt a tv fo 20 quid toshiba 42 inch back lights had gone so i found a couple lights that wasent working all i did was removed the bad led and i solderd a light of a old xp pc all the lights came on did notice theres two not working but like i say its working lol made my day this tv i fixed well if it goes again i think your way is a good way to bodge my tv . by the way this was my first ever back light fix just yoused my anishutive and i think the tv brand new is about maybe 200 to 300 pounds .this is more like a new hobby to me well it saved me 90 pounds cause thats how mutch fix it shops charge these days
Just one more question... How much amps does a single led consume? Please rply
Love that clock!!!
Yes so do I that is why I put the effort into making a nice piece of furniture out of it.
+GadgetUK164 You should see it now. Has my VFD vu meter on it.
They are brighter with 24 volts right?
They won't run on 24V unless they are cut in the middle, and rewired as series/parallel. I have them in my stereo cabinet, they are very bright.
Have you ever wired up four 12 volt power supplies in series? That might be less work than trying to tap an etch in the middle of the strip.
Took all of 2 minutes to wire up each one. I gave the ones away I didn't use and the guy I gave them to tossed as it was "too much work" to make them work.
How many volts does 1 strip required
A full strip 48, 24 for half strip, so I cut the trace and wired to run off 12
Do you need LCD TV backlight belt?Our manufacturer can provide you with a large number of products.
I have one of those B&D RTX...I actually like it better than the Dremel
Hey man were u order them light at??
inside any led lcd tv only 6 led will work some tvs have 4, 5, 6, 7, 8 and more, just pick up some laying around the curb
So are all 12 leds connected to the same 12v power supply??
No I cut them in the middle. 4 LEDs in series on one side 4 LEDs in series on the other, both banks of 4 seeies led in parallel.
@@12voltvids Thanks for replying. So how many leds in total? and how many 12v power cables?
@@sions9717 I used 3 stripstotal of 16 LEDs under the cabinet, and that draws about 1.8 amps @ 12v
1 adapter for 3 led lights seems overkill. You’ll need a whole lot of adapters, or am i getting it wrong ?
You use 1 adapter for all ?
1 adapter for all the strips. 12 volts drives 3 led in series nicely. I have 6 per strip running 3 + 3 in parallel, and 3 strips. They load down a 2 amp supply nicely.
@@12voltvids Whoa, ok so to understand correctly, all of the strips of LEDs you show in the video, if you wired them in series as you instructed, all of the strips of LED can be powered by a single 12V 2amp PS? (of course minus the LEDs in the middle that you intentional disabled out of the series.
thank you...
Is that a dc or ac?
DC
Oh.. So all tv leds are dc? I thought its ac....Thanks alot, vry helpful sir... I hv one broken tv, will repurpose this way....
I couldn’t tell exactly what trace you cut!
LEDs are supposed to be current driven, not voltage driven.
As their temperature increases, they will consume more amps. The more amps they use the hotter they get.
You need to feed it a constant current source.
Great video .... 😂😂😂
Perfect
Thanks, I picked up a bag of cutoff's from a second hand electronics seller. Never did figure out how to make them work properly, I have some groups of 2 that I got running off my 5V power supply, they light the bottom of my computer desk well enough that I can find little things that fall there, I don't use it for keyboard or anything, just crap in my makeshift desk that sits beside my power recliner, which supports me daily as the narcotics relieve the pain that has been with me since the accident in '92 that retired me from the PD and made workers comp the almighty god above me, who watches me with evil intent, trying to get out from under their responsibility of keeping me kicking till my body gives up the ghost and they can stop paying me. They already declared me retired a few years ago and cut my payments in half, that hurt like hell and left me and the wife arguing after each payday weather we should by ground pork and an extra loaf of bread, or hamburger and rely on the State to give us a few potatoes when they come to town.
You should have sold them on ebay.
so many already do it, and there is always that 1 guy that sells it for nothing and then offers free shipping
I connected a 9v DC output transformer to them and they light up dimmly.
why not do the + and - connections directly where is the faulty led by eliminating it?
