I wasn't SHURE™if you were going to figure this out. But who am I kidding... You R the "FeedbackLoop Whisperer" Always the best mYstery nOvel on the shelf. Thank you for the video. Cheers from So.Ca.USA 3rd House on the Left (please call ahead before stopping by)
Excellent result - probably good that you didn't find the faulty MOSFET first, as you could have fixed the issue with the power switch and still had 5V on the 3.3V rail without knowing it.
I found a photo of this part with 52APR marking, so you are right, it must be FDN352AP. So my replacement has lower on-resistance, but FDN352AP can handle up to 30V (as opposed to 20V). The actual voltage is about 15V, so it should be fine.
Nice! Very odd trail of evidence in this one, with those separate issues. Perhaps previously repaired by a gorilla! :-) Looks like something I would have done!
Glad to see another video from you! Excellent as always
Awesome repair, as always.
I love the incremental methodology
It's always nice to learn how problems can be solved even when there isn't a schematic on hand.
very nice repair as always.
The unknown MOSFET is FDN352AP by former Fairchild Semi.
yes, you must be right. someone already suggested this. thanks
Schön wieder mal nach langer Zeit von Dir zu hören. Ich mag Deine Videos sehr! LG
I always like before I watch. Quality content guaranteed with you
I was gonna say exactly the same thing. I do that too
good work 👍🏼
Great repair job
Thanks once again for an interesting repair.

🎉 Hi! Nice repair as usuale. Keep up the good work. Regards from Italy.

it would be hard to miss the burned voltage regulator
Very well done, again. :)
Q6000 is likely FDN352AP, marking 52APM (M is for datecode).
possible, but the datasheet shows XXXM format

Excelent Great great work. 4.8V can fried the procesor.
like a BOSS!
Interesting repair. There's no explanation for the melted connector. I guess the owner's self inflicted wounds. Thank you for sharing.
Great troubleshooting! How did you know to use a P-channel MOSFET if you couldn't identify it from the markings?
guess based on experience. looked fairly obvious to me
Welcome Back 😍😍

Nice
It's been awhile
Hello sir, what do you charge for a service/repair?
How can I reach out the you please
Where have you been? I thought you gave up on educating folk😀
