- In this video, I will show you how to make an LED light panel salvaged from a broken LED TV. This LED light panel is super bright! You can even power it with a battery pack so to make it portable and you can bring it anywhere you want like going camping, working on cars, working outside at night, or make it a giant flashlight...etc. Watch part 2 where I installed these LED into a smaller package and more portable: • DIY: Home made LED lig...
Salvaged THE EXACT LEDS and for the life of me couldnt figure how to wire them. You are the greatest man. Thanks so much for making this.
Looked everywhere for a solution to this very problem!! Thank you!!
Sweet bro. I'm always needing more light to work, especially since I've gotten older. Gonna make one of these SOON. I just tried unsuccessfully to repair an LED tv. Broke the bezel. Now I have the lights left from the back. This will do nicely for my workroom to make repairs. I'll finally have enough light. Thanks friend. Good video.
This was the most helpful video I found on powering backlights it was easy and simple
Thank you for sharing this! Can you make more videos like this with the led lights and how you removed them from the tv?
I salvage and use these types all the time, the plastic domes are actually diffusers, you can pop them off without harm to the diodes, and the light output will substantially increase. I prefer to use voltages under 20 volts d.c. as the current consumed rises exponentially above that value but the increased light output is really negligible. I have made movie poster boxes, and illuminate all my workshop equipment with these, you simply cannot beat the price and savings in electricity costs to use- if you find them roadside like I do. ☺
What do you do to power them? I'm looking for a plug-in solution, personally. My TV just died, repair costs were too high (motherboard was bad), so I took it apart, and remembered that you can turn these into efficient lights, but I would like them to be fixed in place somewhere long-term like a standard light.
@@JohnSmith-td7hd I salvage the power supplies from printers and scanners found roadside, they work very well and are free. ☺
Brother, Yours is the only video i understand. not every video is for professional PPL. You explain so new PPL can learn. Thank you.
Great video, thank you for sharing. Do you need current-limiting resistors to protect the LEDs? I am not sure if the original PCB board of the TV has them or not.
Thank you. You video has answered a lot of questions I have had. I tear down Broken T.V.s for scrapping, but always save the LED strips. Did not no how to go about powering them up after taking them out of the TV's. Now I have a clue! The bare wire strips, that you soldered in parallel, are a bit scary. Maybe cover them completely with electrical tape, or a liquid rubber that can be painted on?
wow well done buddy you gave me the great's ideas to for these thank you keep up the great ideas you have wow two thumbs up take care stay safe .
This video was amazing thank you
I have done 2 of these, 1 Samsung 42" and a Vizio 55". On the Samsung, I removed the input board keeping the power supply board. When I plug in the AC power, it immediately turns on. With the Vizio, I had to leave the input board in and I must use the power switch or the remote to turn it on. How I realized that I needed to keep the input board was having the light on and start unplugging cables. One of them killed the light, so put it back. Since, I wasn't going to try to sell the cards, it didn't matter. I didn't think about it until it was too late, but if you can turn the brightness up to max before removing the LCD board do it.
Bill P - dude... I smacked myself when I read the part that said to fire the lights up and work backward... I had luck with 1 tv (removing the input board, and plugging in for the lights to work), but the next tv (different brand I believe) gave me a magic smoke show and a scare that made me pack up all my screens until now..
Can you please elaborate on your recommendation to get the bulbs to MAX before removing???? I don’t get what you’re saying, but I want to get it. Lol thanks
@@flojotube Sorry about the confusion. The one that I recommended to increase the brightness before tearing apart, turned out to be a plasma tv with VERY thin fluorescent tubes in the back. As we know they deteriorate and lose their brightness. Since then I've found that you only use LED/LCD tvs and when you apply power they are full bright. I haven't bothered to figure out all of the fine details, but I plug them in and if the backlight comes on, I tear them apart, usually, you can get rid of everything except the power supply board and the LEDs will light. In your case, you might unplug the boards that are not the power supply board and see if it works. If the PS is toast then you might be able to figure the voltage to run the LEDs and provide direct power.
Good afternoon dear hope all is well with you by his grace I'm very grateful about you
This is my first time doing this and I took the white paper in the lights up is there anyway I can glue them back to the board and it be alright
Good info in this video, Ownage Pranks.. I didn’t know you did DIY on the side! The narrations were brutally painful and this could’ve been done in half the time, but it was worth the sacrifice. Thanks.
My question is can you just hook up to the four wires that are coming out of the whole setup and power it? I have 75 inch flat screen led.. has four wires from t.v. how much power would that need and why four wires?
How many Amps? I am trying to make one.
Bro if I have an edge light tv(broken), can I try to convert to this tipe of installation led to revive the tv ?
so my LED strips have 5 leds but 2 strips connect together making 10 LEDs how can I power it to make an tattoo table
thought you where gona put them in that small monitor ?. also is there not a lot of resistance with that think steel wire u used ?
Link to video in description for part 2 where I put onto smaller monitor. These LED's use little power so no worry much about resistance on wiring.
Great video! Can you tell me how many amps the whole array ran at?
i realize I'm quite off topic but does anyone know a good website to watch newly released series online ?
Where is it possible to buy led strip for philips tv 46pfl5507k/12
Please I need to know can I glue the lights back on the board and they'll be okay
what CRI (color rendering index) do these backlight LEDs usually have?
tazztone Negative 95 CRI
Hi so i made mine too with 3 strips led, 10 across @ 3.7v, with a power supply of 32v, 375 Ma from an old printer, hook everything up and turn on,,, but only turns on for 5mins turns off. thanks for the help
awsome videos!!
I hope you didn't have any overheating problems putting all those LEDs in a smaller space. LEDs do overheat if you confine them too much.
I have the same kind of led strips from a broken samsung tv. 12 x 7 led strip, 84 led total, I want to do a project for my camper lights sistem. So i have 2 options, i can power it from the tv power supply at 220v, but i have to keep them in series and im depending on 220v campings power, or i can put them in paralel and using 2 12v car batterys and i can go offcamping. So you say 3.7 x 7 = 26v / led strip. Can i put 12 together in paralel. If i will have only 26v power consumption, on a 24 v car batery bank, that mens only 1.08 amps. Am i corect?
You can only power it using 220V AC if you have the mainboard, power supply, and all electronics connected. Your TV model might not have the same 3.7V LED so you may want to test it first. But if they are the same, you can do 26V and then put all in parallel and power by the 24V battery which is actually about 29V when your car is running (or when it's charging). That's a bit over volted so you might want to add a resistor to limit the current.
Hey guys does anybody Know if these led strips need a resistor kinda like any other led, without it wouldn't they burn up, also if this is true what kind of resistor or how many would you need for this setup, I'm trying to rip out the guts to my old kitchen florescent light and put these strips in but I'm not 100% on what I'm doing?
You only need a resistor when the power source has higher voltage than your LED is designed for.
u can use a cfl bulb to power the cfl's in the tv
If you find an old scanner printer that has the ccfl tube in the scanner, not the led bar, you can use the driver circuit from it to power 1 of the longer ccfl tube from an old lcd TV. They usually take a 12 volt input to make the ccfl inverter work. The inverter module is small, about 1 inch by 2 inch.
Great video. 27 volts, yes, but how many amps?
Very low amps. I'd say less than 1 Amp.
Each 18650 battery is about 2-3000 mah. It will make your lights stay on for a longer period of time
How do I stop a backlight from auto dimming? I have it broke down to this exact point
How do you power it?
Is it possible to light up the strips with car battery?
Yes but you'll need a boost converter to boost up the voltage because it's more than 12V
Hey bro nice Video thank you
I have a 24V Battery from a LKW its possible?
Thank you
Do you need LCD TV backlight belt?Our manufacturer can provide you with a large number of products.
When you change to parralel you need a lot more amperage! Amps are far more dangerous than voltage!!! A static spark can be a million volts but generally won't kill you because the ampere's are very low! Volts = Speed Amps = Pressure! Think of a car engine Volts = Horsepower Amps = Torque. So if those LEDs need 120v but only a fraction of a amp it's pretty safe but if the 20v needs 10-20 or 30 amps you might have a problem if you get zapped! 1 Amp can KILL! Not trying to scare you but I have formal training in the field!
Voltage = pressure, amps is like volume,,, He was a bit hyperbolic,,, you're thinking the right way but it needs to be a lot more than 20 volts... One Truck battery can be up to 1,000 amps, two of them in series is not going to kill anyone (some diesels are 24 volt systems)... My welder is around 20 to 30 volts spiking an upwards of 40ish at 140 amps, I do get a noticeable tingle if I'm sweating enough... It' is fascinating that a 1 amp is plenty enough to kill though the voltage potential still has to be enough to overcome any resistance,,, Rule of thumb for playing it safe (or thumb to thumb lol), hand to hand is about 1,000 ohms,,, but this can change depending on things like dry calloused hands or being outside sweating like crazy with soft pruned hands.
How does the heart feel? Nothing to worry, it's just electricity flowing across your heart.
Your heart requires electricity to run. That comes from a pace maker. Without electricity, it's dead.
y'all some fart heads
@@kirk5452 😂😂 way to chime in there, champ LMAO
What is the voltage of these LED strips? as I pulled 4 of these from a cracked screen TV and I did not measure the voltage of them before disassembly. I no longer have any parts except the 4 LED strips
Mine have 11 LEDS each with 2 strips in each power channel
the voltage of each LED is usually printed on the strip itself. If not then try an adjustable DC power supply until you can light up the strip then that's the voltage of the strip.
A common voltage for Leds are 3 volts for each Led,FYI.
Thank you, sir!
Hallo
No disrespect intended , just curious on your accent. Great video it helped me a lot but I can't place what nationality you are. Just curious, again I don't mean to disrespect. Keep up the great work . Cheers
Have a question can someone help? I have a 55 Samsung smart tv. I Was told back light array panel needed to be change. I was told by Samsung and Best Buy. The part cost $1000 and the back light come with the screen. But have seen video with people just changing the strips . My question is can I fix this tv without ordering the screen with back lights and just order the strips model #on tv UN55D6000sf there is no power issues the meter read fine on power board. Can someone help with is question.
I'm assuming you don't need help with this anymore?
Did u aver fix ur tv
Pravin mahida
3:25 Fk Yeah BuBBle!!!
Haha, plastic bubble thingy!
Where do i buy led strips?
www.shopjimmy.com
As far as I have seen, It doesnt make sense to buy tv led strips for this use... there are waaay cheaper leds that will work to make led light arrays.. just search ebay for 3w led... this would be useful I guess if you salvage them from broken led tvs but the leds are the most common failure on an led tv so why not just fix it at that point? those tv leds have a short life unless you underpower them. you need a good heatsink to make them last at full brightness.
MrKirbinio these are constant current not constant voltage though. that is massive deal
LOL Thats one strange accent you have mate. Im on the same page as you mate.. same led array from kicked in samsung UE46F and broken back lit viewsonic monitor. i managed to get small led strip of laptop screen. so ill test that first.
LOL, my accent is a mix of Simon Cowell, Barack Obama, Arnord Swazernegger (or whatever his last name is), Jackie Chan, and Kiichiro Toyoda.
It sounds Asian, but with a little bit of a southern drawl. Pretty cool. Thanks for the video, looking forward to seeing #2.
00:44 of information.
18:00 minutes of ?????????
dude your accent is litterally like 3 or 4 all in one, never heard anyone like it, im not joking, its part british scholar part australian part black gang banger, part south african tribeman . litterally i swear your making it up because every 2 or 3 word it changes dratically, wtf
When doing a project talk less and do more.
Just go to Home depot and purchase a lamp, less than $50.00
... Ya just don't get it Ben.. ya just don't. I thought I raised you better than that, Benjamin.
You over explain and repeat your self. Video could have been done in a half time....negative positive... Negative ...
Positive ...positive ....negative...26 v...26v.......
He's making sure that everyone clearly understands. Some don't catch on as quickly as you and I
