- in this video {769} LG Flatron Monitor W2241S Power Supply Fluctuating, this power supply was fluctuating in secondary. i found current limit resistance in series of auxiliary winding open circuit. and checked 1N4148 and 4.7 ohm resistance at MOSFET gate was open circuit. the voltage at vcc capacitor and output section were fluctuating. this board is using LAF0001 (this is LG part number) while its equivalent part number is FAN7601 pwm controller IC. board number E8NBW4183090417199 AIP-0185. lg model number LGP-002-L, LGP-002-H, e148279, tu78q11a.

I took my time and checked on YT channels how people explain SMPS power supplies ...I can say--- YOU ARE THE BEST! Greetings from Croatia!
Lots of thanks and love from India
Most welcome!
Mashallah great skills job keep it up best wishes big thumbs up
Thank you ❤, I really liked this video 🌹
Nice work my brother 😊 give you super 👍 keep safe always
GOOD TICHING KARTE HO AP THANKS 👍👌👍👌👍
Thank You. good video
We never stop learning... I have enjoyed the video and I need more sir. Thank you
it is my pleasure
Thanks a lot master 👏🏼
Segui tus pasos muchas gracias, me extraña q no verificaste el TL 431 pero tu razonamiento fue OK. Salu2
muchas gracias. la mayor parte del tiempo TL431 permanece seguro. Si en alguna condición el TL431 sufre daños, habrá daños visibles. Si obtenemos alrededor de 1 voltio en el lado LED del optoacoplador, eso indicará que TL431 está bien.
مبدع كالعادة
Good Morning & Best Wishes Friend
you are my inspiration for this work.
बहुत ही हेल्पफुल वीडियो है।
Thanks a lot ! I love your videos! Long live!
Her zaman olduğu gibi güzel video olmuş. Teşekkürler kardeşim. Allah cc emanet ol.
çok teşekkürler canım kardeşim. Allah korusun
Informative vedeo, I was waiting tv repair series and also requested you to make vedeo on TV repair. Thank u so much. God bless you.
Masha Allah.... Thanks from Germany.
welcome and special thanks
as always, Excellent video. thank you brother for teaching me.
Masha Allah another informative video
Many many thanks
Very good and useful information sir thanks for sharing this knowledge to us
Very informative video..nice.......!
Good one...thanks sir ji....
Very informative video. Thanks sir
best regards and special thanks
Dear Brother, Thanks so much for educating others who are engaged in electronics. And each and every video you upload really informative and I do appreciate it so much. Just a request, can you do another video related to Portable Power banks with Car jump starters please? Have a great day!
I am Jamal from Sri lanka
Excellent thanks for sharing this informative video
Mr. Haseeb, once again thank you for the excellent videos. I look forward to and enjoy all of your videos. Didn't you do a video on how to trace a circuit board in order to troubleshoot the board? If not, can you in the future do one?
Very informative video 👏👏👍👋
Nice informative vedio
Hi friend thanks for another informative video
Thank you very much Sir 🙏
it is my pleasure
Masha allah brother great work..nice
thanks a lot
Analisa yang sangat baik❤
wow really great
good vidéo job
Thank you always. Can you tell the model of the tester you use please?
Great!
best regards
hi sir press power button and range simultaneously to disable auto off of your multimeter aneng q1. you hear 5 beep tones to disable auto off function.
Thanks for the video.
How do you find the schematic diagram
👌👌👌👍
Mr Haseeb thank you for the informative video I would very much further my knowledge in this field of analysis and calculus do you offer any online classes or m can you point me in a direction where I can start
sir may we know how you get data sheet as always!
Very nice. please sir tell MGD623 n alternative igbt.
👌👍
👍
thanks a lot
It is difficult to see the schematic . As I understand it there were two faults 1 . A fault in the auxiliary supply used to power the controller chip - the resistor in series with the auxiliary winding was open . 2 . A diode fault in the feedback circuit ? Is that correct ? What was the root cause of this fault ?
Sir where to get this kind of circuit diagram for different electronics?
❤️🙏👍
Hi, where do you get all the schematics from? Can you make a video of where the schematics are from. Or is it secret? 🙂
no dear there is no secret. just search the model number, board model number, and download circuit diagram from google. i shared techniques in my many videos number 558, 568, 654, 725 etc
Sir here I could not understand that u measured the output voltage across the diode but not with respect to -ve.
these are blocking voltage which drop across the diode, it shows us the transformer and diode's health. no need to use reference for voltage measurement across a working diode
سلام عليكم، please sir, why you dont check condensator capacity ?
ap diagram kahan se lete hn website btain
Sir how can we make a simple circuit to run a dc motor (uvw)with shoft start and (overload protection if possible in less expense)
Which ic can we use for igbt gate drive (vft generator)
Please reply Sir
Thank you
Lk dn
thanks a lot dear sister
Aslam o alaikum brother Mera taluaq AP k city Sy h brother sir crt tv china ka sarcut p ake vedio bna din point vise
Haseeb meri require ment ha 60mfd 600volt kya ma do capictor120 MFD ke series me lagane se working voltage bade ge kya ya 60mfd 880volt hoghi kiuyo ki ya ma use kar reha hu 440volt across me220 k resistor par capacitor foog jatha ha wah pe 520volt takh athi ha
Sir please tell me how to download diagram of any circuit
jese apka volt ohm sab mention hota hy wo wali dia gram
Please may u give me ur soldering iron part number.I need to buy.
it is WELLER WR3M rework station. made in Germany
Sir, can we get the schematics.

@@HaseebElectronics Thank you sir :-)
is this pattern universal?
yes dear
most the switch mode power supplies are designed for universal input voltage
@@HaseebElectronics can you send me this diagram on pdf thank you
