In this video number {1144} 24V 150W LED driver output fluctuating. I explained CLM dc 150W 24V VST AC/DC LED power supply, stabilized output voltage. its output voltage were fluctuating. in troubleshooting process i found vcc section damaged. after replacing SMD components, the LED Driver started working normally

Really love these smps repairs but can I ask how you knew what the diodes were as no markings. Thank you

@HaseebElectronics 4 дня назад

best regards and good morning black ribbon diodes in primary switching area are fast switching rectifiers, approximately 99% diodes have 1N4148 diode specifications. because in high frequency switching are it needs fast recovery diodes. nearly 99% diodes in switching side are fast switching rectifiers (very few diodes are zener diodes). so we can use diodes from any SMPS's switching section

Hello Haseeb, what a professional job! Can you tell me at 4:57 how to know if it might not be a zenner diode?

@mahendragadhavi6811 4 дня назад

Good work carried out, if We have theory,there is no problem to.. detect fault . I read some comments I think Haseeb is your firm name and your good name is Mr. ASHRAF am I right ?

@HaseebElectronics 4 дня назад

yes, you are right, when anyone gets idea of circuit flow, then he can fix it simply and logically

Salam. Very interesting pathfinding technique. Useful when parts are completely damaged. What does resonnant mean ? Thank you

wa alaikum salaam brother resonant converter is switching topogy named as resonant converter topology

Sir am following you very long time. Why don't you prefer the smd hot airgun to remove smd components? You work is really awsome. 🎉🎉

@HaseebElectronics 4 дня назад

I have hot air gun I use it for some special works Otherwise i love Soldering iron I feel relaxed with soldering iron Hot air makes me crazy 🤣 specially when we want to remove one component and then we start to search the other missing components which fly away with hot air hahahahaha 😂😂😂

@rajkhumar001 3 дня назад

@@HaseebElectronics yes sir I seen your last desoldering video. One component is fly away.

Great video. A few 15:00 where you find it is an npn transistor, how do you know it is not a small mosfet?

@bzfarbodjz 2 дня назад

can you plz tell what microscope set are you using ?! it has a great image quality

@omiza3416 4 дня назад

Sir this npn transistor is comfusing me becuase is connected before the load, if i got it right.

which one temp should i use on power sipply pcb ..250 degrees or 350 degrees..????

which one soldering iron fime to desoldering pcb components power supply cause i have one soldering iron of 30w but doesnt desolder power supply components properly it takes too long for heating..

@vishalagg7442 3 дня назад

Sir when switching mosfet of power inverter is short battery terminal are also short is very dangerous for lithium ion battery so please give us solution
