That's amazing how you make a backlight tester. You are absolutely genius.
Thank you sharing this video my new ako bago natutunan idol jun
Wow nmiss ko tuloy trabaho ko s electronics mga diode n yn capasitor tantalum at resistor
thanks for sharing this, galing mo naman host
Wow genius😍..Judi G official
Thank you idol. Sukli po kita
Thank u for sharing💖
amazing, thank you for sharing. jerrys vlog
galing mo idol..thanks for sharing
Welcome po idol. God bless thank you rin sa support lagi
New frend sir,, sending full support #gcc
Wow congrats bro ang galing mo
Thank you po. God bless
wow great info na video kapatid love it gcc
Informative video thanks for sharing kapatid...
Thank you po.
New friend Goodluck Full support.
Very clever!
What clever??
Full pack done boss
Good circuit ,thank you .
Thank you
Cool ,Ang galing mo bro
Maraming salamat Lods. God bless
Nice galing nman
Thank you chen.
Salamat sa pag share idol...try q po eto
Thank you idol
Nice bro
Wow...amazing. Lahi ra gyud ang bisdak ba!
Maraming salamat Lodz. God bless
thank you for supporting my Premiere, sending you 2 hours WH to support you, playing all your ads
tamsak na may kasamang kalimbang.
Thank you po.keep safe
Good morning Sir my new subtriber,, thanks my share knowledge God bless.?
Thank you lods. I'll back to you
Amazing talent
Thank you idol
Wow galing mo,,
Thank you admin
Instead of using a multimeter to know the voltage of the testing led, diode, zeners can you enable to have direct reading of this by adding a digital display?. If such a display had to be incorporated what type of alterations had to be made in this circuit? Please provide me the details.
Hilig ko rin yan lods ....
Thank you lodz
galing galing mo sir keep up liked it gcc
Is it safe to touch output probe??thanks
Thanks sir
salamat sa share idol from Gods Creation
Galing mo..pde pa send diagram pls...😊😊
Sa ko po send ang diagram boss
In America it is 120 Volts instead of 220 V. Is the parts value will be the same???
hello . why do you use 330k ohms resistor at 0.50 minutes ?
Amazing
Thank you lodz.
good job host
Thank you po. God bless
Sir salamat sa pag play sa akin..mula kay maam ilyn tv
Welcome idol. Nakasalang na mga ls mo ngayon. Send ko kay ilyn resibo.
Maraming slamat idolll
Kuya alas is here....
Maganda bro problema lang jan dilekado lang kc nangunguryente
Oo nga bro may ground tlaga. Wag lang hawakan hehe
Wow
entry to idol jun2x kay ate judi bka sakali manalo ako, hahaha
Ganun ba idol. Hehe hindi ko alam. Noted idol
Your back ground music is yery high otherwise nice god bless you 🙏
Thank you
wanna try this :)
Thank you idol. God bless
i made it today successfully.
Congrats. And thank you.
Hello! Thanks for the tips. Can i use 1,5uf /350v instead 1,5uf/450v ?
Yes sir. You can use 350v
Nice
Thank you master.
will we get shock from touching the output ? can this be used for checking cob and smd led ?
Yes, you well shock if you touch the output. But its not danger because the current is auto reduce.
Is it the current, or the voltage that auto reduce?

👍
What do you think about the led tests I did on my youtube channel?
Indonesia,👍👍👍
عالی بود فقط بااگه پراب جابه جابشه +و-چی میشه
wow ECE/ECT din po kau?
❤❤❤
Kindly show checking of single led. Can we check single led with this ?
Yes. You can chech one by one led.
can i use this circuit on 120 volts ac?
No. Its for 220vAC only.
What modifications would be necessary for it to be fit for 120vac use?
sorry to be offtopic but does anyone know a method to get back into an Instagram account??
I stupidly lost the login password. I would love any help you can offer me!
@Messiah Wesley instablaster =)
@Cooper Ian i really appreciate your reply. I found the site through google and I'm in the hacking process atm.
Looks like it's gonna take quite some time so I will reply here later with my results.
@Cooper Ian It worked and I finally got access to my account again. Im so happy:D
Thanks so much you saved my account !
@Messiah Wesley happy to help :)
New friend here_judi g
Thank you po.
Yan need ko now idol.cra backlight.ng.tv ko
Saan po ba location nyo idol? Marunong kaba sa electronics?
Can i use capacitor 450v/10 uf and 450v /2.2 uf
Yes.
Why led not bust at high voltage dc ?
The DC voltage is auto reduce.
خازن22uf450v ندارم ایا؟33uf450vمیشه؟
Sir ji Sony led tv lg tv ki agar ek ek light cheek karte hai to sahi dikhata hai magar bo light kharb hoti hai asa koi 6 volt led tester ka video jarrur lod kare thanks
Sorry sir. I can't understand your language. Please translate in english.
sir my tanong lng gumawa q nyan ok naman napa ilaw q pati ung isa lng umilaw naman kasu nong binalig tad q napundi ung led...nd bapwedw balig tarin un salamat
Bro sorry late reply.. yan ginawa ko hind naman nakakapundi kahit baliktad. Nilagyan mo ba ng dalawang 470 omhs 2w ung out ng positive?
@marvin castro sakin dinagdagan ko rin bro kabilaan nilagyan ko. Kasi kapag ung kabila lang lakas ng ground.
@@JunjunTech master kung lalagyan din ng 2 470ohms ying negative side wala ng ground?
Mạch này có tuyệt vời hay ko thì tùy mỗi người, nhưng đối với tôi có ngày nó giật cho le lưỡi 😢😢😢
master magandang araw sau hihingi po sa sana aq ng pabor n bka pwed bigyan mi q nh kopya ng diagram ng back light tester bago lng
po kc aqng technician
Yan ang talent ba. Takot ak sa mga ganyang bagay lagi na ak na ground eh. Medyo Truma na. Judi
Hehe kapag hilig mo kasi walang kadalaan tuloy parin khit na ground pa. Thank you po.
sir my grown b yan oh nakaka kuryente yan.kc 220v yan eh
May ground yan sir. Pero hindi naman delikado kasi auto adjust naman.
Wow dmi views
Salamat po sa pag Play.
Playng parin mga vid mo sakin untl now
@@JunjunTech at baet nmn po salamat ,pa add po Mh A ce ,slamat
Hindi naman po. May gc kaba. Para marami makatulong sa wh mo.
@@JunjunTech wla nga eh hehe
Yetrum gak boss outputnya...
english please.
How connect volt meter in this circuit diagram
Connect at output DC.
marunong ka pala from kasm
Salamat lodz.
Any risks to teach output prob.?
They ground in the output.
@@JunjunTech not clear.
Please, tell me what is ground.?
They have current in output. But its not high voltage.
the scheme is not valid. I burned 2 parallel resistors 470R when I measured the strip with diodes
sir,kaya ba nyan un tatlong strip ng backlight sabay sabay.?tnx po.!
Opo Boss kayang kaya nya pailawin ung tatlong strip ng sabay sabay.
@@JunjunTech tnx po.!
@@geraldocrescini6750 welcome sir.
Mixed up
How much (mA-OUTPUT) and how much (V-OUTPUT).
250VDC output
pwede kaya backlight drive yan?
Hindi bro.. pang tester lang tlaga sya.
Can we use it as led driver ?
That’s what I would love to know, what’s the maximum array of 3v led and 6volts led it can power, for how long continuously?
Ser poyde ba hawakan yan ser sates prop
Hindi po sir. May ground sya.
Pwede po ba 1.5 400v
Opo pwedi po sir.
Okey boss New V pasyal karin sa chanel ko salamat boss😁😁😁
Thank you idol.. copy idol suklian kita.
Makalikot karin pala ha...
Oo matyaga ako magkalikot sa mga ganyan.
good day sir! naka buo ako.. tanong: may epekto ba kung sa 110v ko sinaksak. 160v dc lang na sukat ko.
salamat sa pag tugon sa aking katanungan..
Kung may output naman sya sir ok po yan. Wala naman problema basta may output sya. Try mo mag chech ng backlight
ok sir... success! umilaw
@@ec8122 congrats sir. Thank you po.
@@JunjunTech ❤️
good day. Tanong: Paano lagyan lng indicator light kung naka on yung unit? anu-anong pyesa idadagdag at saan ikakabit. salamat sa pagtugon.
I testing ..don't good result...burn led lamp
Make sure you follow the correct Value of resistor.
@@JunjunTech I used a 270 ohm resistor instead of two parallel resistors
Why 270 only?? In my video I use 2pcs 470 ohms 2 watts in parallel. You didn't follow the correct value that's why you got a bad result.
@@mohammadafaghi6082 watts matters. One 270ohm 2 watt power dissipation 2 watts, two 470ohm 2watt each in parallel =235ohm and 2+2=4watt power dissipation.
The problem is, his LED got burnt not the resistor ..parall
el 470 ohms resistor almost the same as 270 ohms resistor but different wattages.. .my opinion only.
Watching lheoda tech nice sharing ka technician invite kita visit my shop. Thanks
master magandang araw sau hihingi po sa sana aq ng pabor n bka pwed bigyan mi q nh kopya ng diagram ng back light tester bago lng
po kc aqng technician
Pweding pwedi bro. Saan ko ba pwedi i send bro.
@@JunjunTech sa messenger lng master jeff mendoza,,, maraming salamat master
master hanapin kita sa facebook anu b gamit pangalan
Taga saan lugar ka bro? Marami kapangalan.
cavite city po master,, jeff mendoza lng po bago ung profile q ung dalawa kmi ni misis q,,,, salamat po master
