That's the thing customers don't always understand. They aren't paying you for only the time you spend on the repair, they are also paying for the hundreds and thousands of hours of experience you had to undergo to get to this point.
I cant even describe how much I have learned from this channel! I have always been into electronics but now I can repair almost anything. I will be upgrading to a better thermal cam soon and then I am done!
You're very good, I was impressed with how you managed it even without schematics, I hope they pass right to repair so you can keep doing your amazing job with even more quality and speed!
I believe it's a combination of 4 factors that makes this guy good. 1) Basic knowledge of electronic components. 2) Correct diagnostic equipment and basic use of. 3) Critical, logical thinking. 4) Experience.
Wouldn't it be nice if customers would tell you the whole story. So much harder having to reverse engineer the series of events. Seems like, unless the DC jack was also getting bad, that the customer did nothing but added a second issue. Great job Alex! I appreciate your videos and explanations.
That second laptop you showed that you fixed earlier in the morning is mine. Can't wait to get it back for my son to use for college again. Thank you!!
I love that even when something causes you to scratch your head..... You refocus and perserviere ... You are truly magnificent ! Thanks for excellent content !! Perhaps one of these days my Asus G703GX will end up as one of these video's
I have the same problem with my ROG laptop, no power! Watch all your vids and greatly appreciate your knowledge. I will be sending in my motherboard to you guys for sure!
he measured 0.4ohm - that's way too high for the bead or any coil (over 6W at 4amps) - I guess he should have zero'd the ohm meter 1st. There are 2 caps on both ends, I'd guess any choke would do.
π Filter ! !first time school helped with something! it's even shaped the same ( 2 Caps and a coil in the middle ) and the coil was missing. the problem in this instance is that it's better to replace with wire because as an RTX gaming laptop the 0 Ohm resistor/Fuse is gonna be under serious load ( 200W give or take )
He is correct when he says it doesn't matter how long it takes, and that you're paying for experience. I do a lot of computer programming and hardware repair and hacks and I can't tell you how many times I have explained things that I've accomplished to other people, and I paint the picture in such a simple way that those people think they can just go out and recreate like "oh, so all you have to do is..." but without them realizing real life isn't so cut and dry and by the time they realize how complex coming to those simple solutions actually is, they're completely dumbfounded.
Very nice fix, also great to see how you analyse the problem and following paths of current to find the source. Missing components are really hard to see... very nicely done mastro
I wondered if that spot was a missing a component at 9:00 when it was in the frame! I’m no expert at electronics by any stretch but this made me feel good. I definitely wouldn’t have thought of replacing it with a resistor, that’s genius. What an entertaining and well executed fix. Well done
Your videos are awesome, you inspired me to learn micro soldering. I do tinker stuff but not with this high level pro soldering stuff. Greetings from philippines!!
This man's a genius. I just paid 55$ at my local repair shop to replace a blown capacitor on my Dell. It was tiny, tiny like a grain of sugar, and even after soldering a new one - it didn't work. So I had to go to another shop about 2 hrs drive away and spend another 75$ plus 3 days to get it fixed (coz they didn't know where the prev shop had screwed up). Alex here does it so easily, I wonder why other shops are unable to do the same.
You would have made an great Police Detective. Another excellent repair video and congratulations on the well deserved court success described in the previous video. Your video's are the first thing I look for when I open TH-cam and your viewers clearly have a lot of respect for your professionalism, expertise and ethical personality.
Fascinating! My laptop is almost the same model. It is in for repair right now... You do very good vids. I hope the guys I left it with know what they are doing? Though I am worried.... Cheers good vid!
I cannot believe how much things have changed. I was repairing boards for a manufacturer back in 1985 to 1991 and all I had was a soldering iron, a solder sucker, o-scope and voltmeter. They also provided a magnifying light. I got into network admin after 91 and never picked up a soldering iron again.
when i was in computer repairing business, i always heard them saying "oh, it was working fine before", or "i didn't do anything"... i mean come on. i know you did something, please be honest so i can fix it fast and not wondering into the rabbit hole trying to figure it out
Congratulations Alex. This looks like a pi filter formed by the two caps under the missing component, that it is an inductor. This topology is used to filter noise from the power supply.
Hello sir , always seem to amaze me with something I will have never looked at ! That’s why your better then factory you and big boss are the repair team
If I were Alex I would photograph working motherboards and keep a library of those images for future visual reference. Time well spent instead of hoping that you have the same board 'somewhere'.
Went back and monitored a couple of earlier videos where you couldn't fix the computer boards even after replacing components that either looked bad or showed up "hot" on the thermal cam. Your reason for the "no fix" on these was always deduced to be a CPU problem. I still wonder why you don't replace the CPU's on these boards. I know that there is a lot of intense soldering on these but I've seen you do that kind of soldering before with ease. Just looking for your answer to this question Sir. Thank you for all your great work!
>I still wonder why you don't replace the CPU's on these boards. CPUs are expensive and hard to come by - you can't really buy them, so the only way to harvest is from boards for parts that are not guaranteed to have working cpus; He'd need the same family CPU at the very least - even then the bios might not support it, unless the cpu is exactly the same. Then the replacement of the cpu is a proper bga rework, which is time consuming and done on bga rework station. Before putting a working CPU he must be sure the board will not blow it up again. So overall - expensive, time consuming and not guaranteed to work and may blow up an expensive component, i.e. the CPU.
i was waiting for you to check the charging ic.. the acdet acok ac_in, the 25v on the gates of the blocking ang swtiching mosfets.. but luckily it was a missing component..
I'm just hooked on your videos. So informative. I'm just a beginer but I learned a lot from your videos. I want to thank you for sharing all these beautiful information..
I have seen the solder Bridge used before as a weak link. I can remember this was, the case when I replaced a PLL chip in a radio transceiver. Maybe it's used to protect the lcd
Working with a thermal camera makes me think about troubleshooting a radio or so in the past with vacuum tubes (or valves!). The first thing you did was looking if the tubes heated (lighted) up..

Is that a GU502 LU MODEL ( Zephyrus M15) ? Mine's display went bad just this morning It's been only 5 months hopefully they will replace it as it is still in warranty
@@kdilac8879 I was using normally then all of a sudden it started flickering and some weird lines appeared then it went blank .No water damage no fall damage. It still displays on an external monitor though which means the GPUs still ok I'm just shocked that it's just been 5 months and already display died.
@@Sanjay-ic7de or it's the screen cable. shorted cable. you need multimeter if you want to check the cable for short. but don't do it, if you still have warranty
That was tricky. Big luck that those solder pads look like that there were a missing component. Thank you for the video. Btw where is your other young worker? Did he left? Greets from austria
it's was quite obvious there was no continuity - and if you look at the board there 2 caps connected to ground on both sides of the pads - gotta be a missing choke. Personally I'd have connected the bench power supply straight to the mosfet with limit set to 1.5A or so.
That is excellent. what is the advantage of having the board plan (drawing)? Asus has the drawing, can I conclude that it is safer to get my gaming laptop GX531 g repaired by them rather than by local repair shops? I assume that the locals have to pinpoint and guess but ASUS not only has the diagnosis port but also the drawing. I have opened it myself but the charger makes that clicking noise like your other video and the voltage does not go through. I have to reset the charger. The laptop was working hot before it went out and did not turn back on. I am going to thermal paste on the chip etc. and see if it turns back on. Then decide if I need to send it to ASUS or locals.
I have never used a thermal camera for troubleshooting. What model Flir do you use? There seems to be about a bazillion different models out there for different applications.

I don't know if I had the guts to place a 0 ohm resistor instead of an unknown component. This experience is what makes you special. Thumbs up.
I have the same problem with my ROG laptop, no power! Watch all your vids and greatly appreciate your knowledge. I will be sending in my motherboard to you guys for sure!
Thank you for sharing your knowledge, I'm learning a lot from your repairs and I'm still training English, thank you so much 🙏
I love that mindset... it doesn't matter how long it took to fix. Your experience is not a commodity that the customer gets a discount because of.
looks like a ferrite bead to block rf interference from or to the dc jack. not really needed, a piece of wire will do just fine.
he measured 0.4ohm - that's way too high for the bead or any coil (over 6W at 4amps) - I guess he should have zero'd the ohm meter 1st. There are 2 caps on both ends, I'd guess any choke would do.

Another amazing fix by Alex. Yes, customers are paying for the expertise, not how long it takes you to fix the issue.
Òne day I will visit usa 🇺🇸 and I will make sure I come by ur shop .God bless for ur lesson and I've learn alot from u sir.
Very nice fix, also great to see how you analyse the problem and following paths of current to find the source. Missing components are really hard to see... very nicely done mastro

A 0 ohm resistor is basically a wire, with burnout protection

most repair shops do more damage than fix the given problem, same is with cars, mechanics/ repair techs have their heads up their asses.
The fact you spotted that without any schematics is amazing 😂😂 Great job :)

I felt so happy noticing that missing part, earlier in the video

Nice repair once again... it is great that you have found a problem... great work as always...
Always great to watch your videos . Learning , troubleshooting skills are just an exceptional. Superb . Thank you
Where do you get all your donor boards? Having what seems like an endless supply of parts and board to compare to seems like it's a lifesaver
As a repair shop they accumulate over time. People will recycle the device with you when it’s no fix commonly.
Nice catch. Good work and keep these coming when you can.
Probably one your best repair videos.
That coil just filters the ripple from the DC adapter , just look for a similar one near the power jack of any other board and you are good to go.
Eagle-Eye-Alex found the missing component.. very cool!!
Always Expect missing component on previous repair attempt...very happy the board is fixed
That was a nice fix! Do you sell any of the chips from your spare boards? I have a asus gl703v that needs a chip and I can't find it anywhere.
finally yt recommends a good channel, i subbed immediately
Great videos as always! The day my laptop won't power on, I know where I'll be sending it to!
I like you are using thermal camera for finding shorted components.
It’s amazing how you try to help people out and the thanks is a bailiff subpoena ya the next day.
I think you can extract coil u needed in video from similar donor board 13:00 and place it on customer's :)
You are totally right. That inductor will fit in perfectly.
6.35 Some of my late father's customers use to complain the job did not take him long. He said you are paying for my knowledge, not how long I spend.
Another great fix alex i realy enjoy seeing your thought process.
You're a genius, Alex.
I have seen the solder Bridge used before as a weak link. I can remember this was, the case when I replaced a PLL chip in a radio transceiver. Maybe it's used to protect the lcd
Excelent job Alex !!! Like always. HI from Uruguay
ما شاء الله... خبره واسعه... حتى بلا مخطط
There was a clue on the first donor board, that you looked at, a coil went from the DC+ input to another big copper pad.
I went back and looked and yes, at 13:00 in the video you see the inductor.
You should do bed time story's, I can't help but listen to you
Super 👍 I have learned a lot from your video
I'd really like to know what kind of hot soldering tweezers you're using. They're not carried in your store.
Working with a thermal camera makes me think about troubleshooting a radio or so in the past with vacuum tubes (or valves!). The first thing you did was looking if the tubes heated (lighted) up..
Well done again Alex you found the missing golden nugget ;)
nice and easy job
Yes and yes 👍 doesn't matter how long it takes.
Good to see you.
Excellent job as always
how do you find the value of the caps or any other component without schematics and where do you buy them ?
Absolutely amazing. Great job 👌

Awesome watching KSA from Cebu Philippines
Some maison replaced that port, and knocked off a fuse brick, which he thought is not necessary.😂😂😂
you should messure coil using H symble on multimeter. i have Victor 88C for measuring these.
You need to set a pedal switch to turn the room light on/off it would make handling the thermal cam much easy
Why would you need to fiddle with the lights to use a thermal cam? 🤦♂

good job mate.
I saw the missing components the reason why b+ rail is misding 19v supply.
Beside of dc connectoe, it looks like a fuse or conductor 😊
check dc jack to mosfet fusing resistor is missing
