Repairing is better then trashing!
Great video!
Keep posting educative content!
❤❤❤
I would never use green/yellow wire as "live"...it´s only used as protective earth....
1:51 This is not correct: It‘s an EMI-blocking choke, not a one to one transformer: A high frequency blocking choke is made of two coils and a ferrite core where L is going through one coil and N through the other coil. A transformer is also made of two coils, but they have much more windings, an iron core and L and N are both connected to one coil. At the other coil you can get the secondary voltage, which is the same as the input voltage in an one to one transformer.
I added a nail with the ends cut off that just fitted the opening of the screw and glued it in. I left a little stick out so that it holds the slider in place better. I used a tap to clean up the screw bore and I used white lithium grease to lube the screw with. Works much better now. Great concept.
Thank you, more of this please, really helpful
Please more video like this. I learn a lot from it
excellent Job. Was bale to follow everything on that repair.
Nice work brother! I love your contents 👏👏👏
Detaylı anlatım için teşekkürler
I am so grateful for this amazing video, I LOVED IT. My sincere congratulations, for the simplicity and clarity with which you explain each step. Today I learned a lot. Thank you one more time. I want to ask two questions and I would appreciate your answer if possible, is a lithium battery charger a switching power supply? The other question is if there are more videos on this topic. Compliments
Excellent Video, very well explained, keep up the good work
Thanks 😊
Good work 👍
Thank you very much❤
Nice video, well done, thanks :)
Glad you liked it!
Hello, I have a question. As a result of connecting a high current fuse to the power supply of the steam machine I use at home, I changed it because the mosfet, zener diode, ntc and 2 watt resistor on the primary floor failed. I can get 12 and 35 volts on both of the outputs, but when I connect the power board to the motherboard, it shows 12v as 2.5 volts and 35v as 16 volts, so the fan and water evaporator are not working. I also changed the capacitors at the outputs of the power board. What other parts on the power board should I check? thanks
Thanks a lot.
Thank you 🎉
Informative ☺️ Subscribed 👍
Thanks and welcome
Nice video Boss
Fantastic job. You could improve your pcb stand with a rotary design in order you could rotate the pcb without removing it from the stand.
Thanks for the tips!
بسیار عالیییی 🎉🎉
Un excelente trabajo y muy bien documentado, toda una satisfacción recuperar esa fuente así, y mejorar la disipación del rectificador, congrats 👏🏼👏🏼👏🏼👏🏼
buenos días estimado, sabes como se llama ese cautin ?
Thanks for this, i have a similar PSU that has problems so going to try to fix it too.
Nice 👍🏽
Hi, Have a question about SMPS initial Max current an SMPS can support. If I use a 1200W Desktop PC SMPS that has common rail, and I connect all 12v together ..can I use it to power a load that takes 100A ? as soon as it powers on will it be able to support this current ?
Never in any electrical engineering class I have heart two 4A fuse in parallel will make one 8A fuse.
Super😊😊😊
Thanks, I have a question. I have a solar panel converter and the led isn’t going on. Can you explain how can I do a checkup of the unit and replace defaults component ? Thanks in advance.
hi nice video,what about the resistor 680ohm,which is 1..1ohm when measured.
whats the white paste you rub on the transistor?thank you
The white paste is heat sink compound
akıllı telefonlar için kullandığımız şarj cihazları içinde tamir videoları çeker misin
Hey can you make a laser gun you can get laser from dlp projectors and you have to limit voltage and current for the laser diodes in the laser gun
all good except the fuses aproach
Agreed
Does an 8 amp fuse make sense? I'd use a 5 amp if powering from US 120 vac and a 3 amp if powering it with 220vac. 8 amps @ 220 is 1920 watts!
Nice job on the diagnostics, and upgrading with better components. Been checking out some of your older content, and this seems much more advanced. Did you get any training in electronics since you started posting on RUclips? Nice to see your channel grow and evolve
(Tnx) Fuse is ok bro but transformer output not working properly any solution bro
Hobby
@@Create1434 try changing the transistors.
In SMPS, there are two SMD IC 2GBH and 1P3. What are those?
How can i understand NTC is good or bed?
Question. I watched your rewiring of the Bosch alternator. What gauge size magnetic copper wire did you or should you use for for a 150 amp Bosch alternator 14 volts?
Seems like you cold soldered the new components 🤔🤔
what does it mean if a resistor doesn't make a beep?
2 fuses in parallel is not 8 ampers
👍👍👌👌
ob2273 koi alternative?
THANK U FOR THE VIDEO SIR . IAM WARUNA FROM SRILANKA , SIR CAN U PLZ SHOW WTZ THE IC REMOVAL TOOL THAT U USE IN THE VIDEO , AND ALSO WTZ THE PCB HOLDER U USE IN THE VIDEO WHERE CAN WE BUY IT
Its a 3d print. Link is in the description.
? what model soldering iron are you using? I want to buy one.
yo también quisiera saber que modelo de soldador esta utilizando....
👍
He is a master in repairing power circuits
Thanks 😊
Holy Indian movie...
Where do I even start?
Thermal paste + thermal pad?
Fuses in parallel?
Randomly removing components?
100W lightbulb with a huge inrush current?
Output not coming in dc circuit what's problem bro
To begin with, check the fuse first.
You can not make an 8A fuse from putting two 4A fuses parallel . Theory is one thing, in practice it will not work properly.
Nice video bro,
Adjustable pcb holder how much bro?
Thanks ! Buy link should be in the description.
Thanks ! Buy link should be in the description.
Aslamoalakum gee Sir kesy Hein sir gee AP ki akser vedio dekhta rehta hun sir ye laptop ke 19volt hoty hein plaz sir in ko amplifier ke leay 20+ 0-20 ya25+0-25. Volt kesy Le sakty hein plzzz sir koi vedio bna kar help Karen jazakomullah
Mai samajh sakta kun aapki need lekin mai project un cheezon ko dhyaan rakh kar banata hun jinhe zadatar meri audience pasand karti hai. Aur is project ki zaaada demand nai hai abhi. Aage agar badhti hai to mai zaroor banaunga.
Boost converter banana hoga uske liye.Market me bohot saste me available hai wase ye. Aap chahe to khareed bhi sakte hain 😊
Bundle of thanks
😀😀😀
What is the name of your soldiring iron?
Siron
Helo bro can you send me shemat this power 24v 14.6 A
If you want 24v 14.6A in watts then 350.4W
Ну так смело лазает пальцами в зоне высоковольтных конденсаторов. Проверить их надо и при необходимости разрядить, иначе можно получить хороший заряд бодрости, если там остался заряд.
What caused this problem?
It was faulty from the beginning, even when i bought the 3d printer. This is from a 3d printer FLSUN V400
480watts @ even 200Vac = 3A @80% efficiency
Since it was made to run on both 110v and 220v..
at 80% efficiency with 8A fuse, the lowest possible voltage will be 75Vac..
Conclusion:
This much supply deviation is only seen in china..
this was probably made in china
can you provide me the circuit diagram
1. 1:51. This part is not called a transformer.
2. "The capacitors are of because they are not inflated." -> You are totally wrong. Electrolitic capacitor does not neccesarly needs to be "inflated" but still can be damaged/degraded inside.
the meter never settles on a reading and you jump to another conclusion
.stop and let the meter settle down on a reading
before zipping jumping skipping away.
Good video. But power supplies are inexpensive throw-aways.
you do not need or want thermal compound when you have silicone insulator pads,that makes heat transfer worse. and paralleling fuses? No. get the right fuse.
मेनेपालसे हे
The resistor that was shorted why wasn't it replaced
The resistor was OK the fault was also across the same point in the circuit, at least that's what I believe having not seen the schematic.
Correct.
noe you vsll it goof,
whats going on
that's the ugliest soldering I've ever seen, but decent job
Keep removing one by one.
Грязная пайка. Колхозно. Канифоль что-ли это.
Hopefully open circuit and under rated load voltage was confirmed
