Tips: don't desolder parts if you are not 100% sure that they're the cause(like mosfet in this video), use soldering iron instead of hot air gun so you don't damage plastic parts that are placed nearby(6:40), don't use soldering paste if not needed, use solder alloy instead, also don't heat up soldering paste without a placed component(wtf was 5:03?).

the same that i thought, but i will add another tip...Dont introduce a high voltage like 12V, with just 1 or 2 volts and high current it will be enough to find the problem. If you put 12V you can damage IC's or even the PCB with the temperature that the damaged component can reach.

Poor IC

Pro tip, voltage injection is done with low voltage , 1-2.5 maximum 5V, due to components like IC's power not been rated for more. overvolting some IC's can lead to false positive result aka heating up as they would be faulty.

Yes your right but that's why he injected that voltage at the output where it's normal to have higher voltages right.?

@Boffin2002

Injecting that high voltage even where a high voltage is expected during normal operation can have an adverse impact if there's a fault. A lower voltage would still show up the short circuited component under a thermal camera or evaporating alcohol. The benefit of injecting a lower voltage is that there is less risk of damaging other components and PCB tracks. You still need to be cautious with the voltage and current limits that are set.

@AKG58Z No, usually you apply a lower voltage on the main supply for ICs, infecting from the main output backward it might cause more components to fail. When I look for faulty ICs, I inject the minimum voltage for them to power up.

@Boffin2002

Correct - I agree that you would normally inject from input to output, I was specifically referring to what was being done here. injecting backwards is where you MAY cause additional problems if you inject that high/expected voltage. That’s why I suggested using a lower voltage if that’s what you were going to do. From input to output is different as you've noted but being cautious won’t cause too many problems.

Why are they failing then? :'D

고장난걸 수리하시다니 대단하십니다.

I had a kuula 65w it failed I open it and saw burns everywhere the main switching transistor was shorted as well as 4 resistors going to on it it's pin and then I started to check every smd capacitor and found one shorted at the output near type c jack/inductor I removed it and the transistor now the short is gone but I will have to replace these 3 things without knowing the other components condition so I didn't repair it, it shouldn't have killed itself if the output goes short due to the fact that it was not built right I didn't try to repair it. Great video by the way I like these kind of things alot.

Great Job.👍

2 questions if you don't mind. What kind of probes are you using. Test probes. Your honest opinion on the larger finrisi cordless scope. I need a cordless scope but can't afford micsig prices when I have a super expensive rigol corded one. I'd rather pay 200 for a tablet scope then buy differential probes to protect either of my scopes.

Thank you for the video. Would you say this power adapter is well built? I'm debating what to buy..

nice

Nice equipment. But why the hot air?

Good! All the best! Once again excellent video! As you suggested, when the “soft starter” for 20v with MOSFET for 20v DC angle grinder powered by battery with brush motor from Einhell, mod: TE-AG 18/115 LI, which burned the controller? I would like to know if it is possible, as I said, to present a schematic or create a circuit with said MOSFET for this purpose? Thank you very much, hugs!

How to know the value of smd capacitor as seen there is no color coding?!

@AKG58Z

You just have to take a guess and replace it with something of the same size it's the easy way. The hard way is to have a same working circuit take the capacitor off and measure it with lcr meter.

In that specific case, it would have the same value as the neighbor capacitor (the larger one). It can work without that capacitor, however it would stress the other 2 as they are in parallel, and they would fail sooner than expected.

Mine is charging, but only with basic voltage/current. As soon as QC starts rising voltage it just turns of and fails changing. Then cycle repeats - restart, try to increase voltage, failure and reset.

I can't see 100% but very unnecessary risk with plugging in and also connecting usb with it powered on, your fingers are very close to high voltage, this could have been done switching it on and off after. Maybe you did it because you're recording, but viewer should see your safety first. Maybe this is ok, but other cheap products are unsafe. Just my opinion.

I got a 65W different build. Gets very hot during regular phone charging. Touch screen doesn't work during charging. Purchased from Ali Baseus store. No guarantee. I do not recommend.

I think buying a new one is more worth it than repairing it. Because my skills aren't that great.
