You are not just good with what you do do. You are also humble. You admitted you don't know what the component is and people with the knowledge about it were eager to give you the info. This is how keep on learning. Respect Boss.
Your videos never get old, something new every time.
Recently I perform microsoldring in a flex cable 3mm flex having 15 wires I sold it perfectly without microscope because my hands are perfectly still but I didn't have solder mask I solder one side other side get desolded only by touching iron on another side for fraction of sec.
The "5X" IC is a RT6575DGQW (RT6575D QFN-20 IC Chip) DC/DC Step Down Controller - if you have an issue sourcing, I have a spare here in the UK I can send to you
@Bishtuku The thermal camera he is using is the FLIR E60. It is a discontinued model
Teamwork! 👍
It finally gets interesting. I'm looking forward to part 2.
Love watching how you work and find problems... Keep up master😊
that ic 5x its step down controler providing 3.3v and 5v..its a richtek ic 5x= RT6575DGQW

How van we figure it out ? Is there any website that can help ?
Well done
Great trouble shooting techniques. Always like seeing you work thru the problem. 😁
Love your videos & solder talents.
I am glad you found the issue. 😁😁😁 other shops here were trying to junk the whole motherboard. I try not to be wasteful. I knew you would find it.

Just got my order in from your shop and can't wait to get started practicing micro soldering. I appreciate all that you do!
It is beautiful about your advanced insight ! thanks a lot..
You are awesome and I wish you lived NY, you would put all of these techs to shame! Great channel and enjoy the holidays. Best regards to you and yours!
Isnt Rossman in NY?
@@kristianjozef3198 he is currently going to be putting his.long rants to good use melting the new york city.snow.
Interesting.. now i know where to go for repairs.. im just few blocks away from your shop lol i live in Northridge
wow that thermal looks awesome. Great quality.
It is up en down mosfet driver it give the gate the voltage to open .it is used in many laptops from the same generation, ik u have damaged motheroboard u can find one. Thank you very mutch for all your very goed videos i learn mutch ,
Hey,it is richtek RT6575C/D. What you have here is probably shorted kbc multicontroler which is powered from that 3.3v ldo line.Very typical case,so before removing that regulator,inject 3.3v into ldo line and watch for heating spots on board,kbc the most.Good luck
5X = RT6575DGQW 👍
5Y = RT6575CGQW 👎
@@hightttech both compatible for this board
@@hightttech how did you find out what IC was on the board? The markings were "5X = 5N M1N" so you don't have to rewatch
a nice idea and not wasting the time but sorry i am new in repair and do not know what is the ldo
@@sarockpashotan it means low dropout
love seeing your vids.. learn new stuff every time
Always a crowd pleaser when you whip out the thermal camera! Its so cool
Great 👌
I'm waiting for next video
Love your vids man keep the content coming
Hello Dear NorthridgeFix, I was watching for some iPhone repair, and got along with other of your videos! YOU ROCK!!! I'm addicted to your videos now:D Best regards from tiny country of Slovenia -> Where your ex 1st lady was born
انت مبدع ربي يحفظك و يوفقك
From what I see it is a synchronous dc/dc step down converter providing 3.3v and 5v . The only supplier i found was a couple of eBay listings so you may need to find donor boards to find this ic.
I am having a battle with HP Omen laptop. Looks like the Richtek L8 on it has similar problems as the device wont start and just blinks shortly while pushing the power button.
I am looking forward for Part II.
Hi Alex Steve from belgium you can use tps51225c for your ic. It is the equivalent for 5X =RT6575DGQW
Can you do a walk through of the tools on your workbench. Would love to see what you use.
He may be quite busy and he cannot afford waste time to come with walktthrough bench area setup.🙄
Not 100% sure but i would guess its a -RT8249A/B/C - Dual-Channel Synchronous DC/DC Step-Down Controller
with 5V/3.3V LDOs. but check the datasheet and pinouts as it comes in a few packages.
NO. "RT8249A/B/C" would be marked "2Q=" or "2P=" or "2N=" ... chip in video is "5x="
RT6575A/B is a dual-channel step-down controller
Thank you👍
what setting is used to test for capacitor shorts? The diode check?
Super hard work thkyou sir
Watching here from Doha Qatar😊😊
Awesome ✌🏻✌🏻✌🏻
Nice try👍👍👍
Nice job, you found the problem very fast. Thats the way it should go. Such a thermal-cam is like a helping hand.👍
Great job, you are the best. Selam from Bosnia and Herzegovina
Which thermal cam that you are using can you mention brand and model
Hey , can you post what thermal camera and microscope your are using in your shop?
Hi , Great video, What thermal camera is it that you use?
good sir 👍👍👍👍
Nice video sir it's DC to dc regular IC.
A very stupid question for sure for all the experienced people we all have been there, but which lead he has when testing the capacitors? Negative or positive? If negative where is he touching the positive? Because all i know it's capacitors are read in Faraday. Thanks a lot for your help.
If you give the motherboard number i will try to get the schematic, thats if the 3.3 v dc ic buck controller, but somethimes if not the ic, i suggest to remove the coil and see whats line have the short, im think is pl301.
thermal camera very rarely used by repair shop in my country because of the price, some using what they call MBR (high current 5-10A) to find fault component
Thanku ❤️👍👍👍❤️❤️🙏❤️
i bet that its the 3v and 5v power supply buck converter ic
Sir me need thermal plz tell me how much and how buy in India ❤️ very useful your all videos 👍❤️❤️🙏
Amazing content
Would you please share the Thermal camera model no./specification sir?
what tester are u using?
I'm an electronic student, which thermal camera do you suggest to start ??
بارك الله فيك وجزاك الله خيرا كثيرا.
When he is testing the components after using the thermal camera, does he leave the board plugged into power? and testing in diode mode?
Hi, Thanks for the great videos you make! Got one question that i hope you can answer for me. What temperature do you use on the soldering iron? Thanks alot :)
700 C is the right temperature..
Thanks
How did you test the last capacitor? Please explain.
Anakartın şemasından PU301 numaralı componentin şemasını bulabilirsiniz. IC yi değiştirince sorun çözülecektir.
Türkçe anlamayabilir
what about a fluke Ti480 , does it good for electronic repairing ???
sir didn't you use flir MSX feature?
I have an asus 403n motherboard with a pwm controller that has similar marks, except mine says 2N=3L E3U.
According to boardview its name is "PWM CONTROLLER RT8249CGQW
RICHTEK WQFN-20L"
Close. But "RT8249A/B/C" would be marked "2Q=" or "2P=" or "2N=" ... chip in video is "5x="
ಅದ್ಭುತವಾದ ಸುಂದರವಾದ ವಿಡಿಯೋ ❤️😍✋👌 amazing and beautiful video ❤️🌹🙏
If the cap was the problem.. which is the value for that component ? Regards Alex italy.
Hii,you can write the model of termal camera ,thanks for all video
👍👍👍👍👍
can we detect any shorts with thermalcam? as a learner will it be easier for me?
Perfect
Awesome
Open the jumper PJ304 and see if the short circuit disappears. It could be the EC is dead and not the StepDown.
IC
@@christozed EC=Embedded Controller. It gets its power through the jumper from StepDown. If the EC is shorted, the StepDown IC goes hot.
@@SiETechNotebookReparatur
IC for step down voltage for cpu, ram, I/O blah blah
@@christozed i do not understand. This IC on this video is a StepDown Controller IC. It makes the 3,3Volt and 5Volt. 3,3Volt goes to EC (Embedded Controller, Super I/O, starter IC whatewer) it is also an IC (Integrated Circuit).
@@SiETechNotebookReparatur maybe not the IC.
The problem is that it can't release the voltage out.
3 leg is the "feedback" for 3.3volt
is there a part 2 for this video?
I have some 5x=5A ic
It's a Single Synchronous Buck Controller.
What if the component you are replacing is not the main cause of the fault, but a side effect?
It is RT6575D chip
Amazing ❤️❤️❤️
I also done one laptop shorted with I/O ic andu another one with ic connected to usb socket
is there a thermal imaging camera that you recommend??
you can use your smartphone
@@kkrott87 how?
@@AravindSniper google phone thermal camera
Hello sir,
do you clean motherboard desktop and laptop use water ?
Isopropyl alcohol
I think that ic is corrosion your opinion sir
Hello Mr.______
WHICH CAM MICROSCOPE CAMERA YOU ARE USING
He sells them on his website. Lots of them.
it a
ISL62386 Dual-Channel Synchronous DC/DC Step-Down Controller ...
RT6575C/D from richtek
This is IS Dual-Channel Synchronous DC/DC Step-Down Controller
with 5V/3.3V LDOs
northridge fix thx for heart i want to restore my acer tab b1 711 but i am in india
how could i do
I've found the manifacturer. Search for Richtek 5X. According to documenr that I've found, 5X is Product Code and 5FM1N is Date Code. You can find that file by searching DS8249-ABC.pdf and look for Marking Information on second page.
And also found RT6575D which is 5X but I don't know if it is suitable for that motherboard
Close, but "RT8249A/B/C" would be marked "2Q=" or "2P=" or "2N=" ... chip in video is "5x="
@@BirhanDursun: datasheet indicates same chip 👍
You should spend more time on it,remove that 3.3/5 volts voltage regulator ic and Check for short again on that cap to find if the short comes from ic or 3.3 volt rail (or 5 volt rail).of course if there is a short under 3.3 volts rail Power suply (that 5×=6f ic)has to be hot.
a nice method!!!
thats very very useful thanks man.
I think this is Dual-Channel Synchronous DC/DC Step-Down Controller
greetings, what is the model of the thermal camera?

@@NorthridgeFix wow....now that is dedication to your craft. Not many shops would/could spring for a $1-4K piece of test equipment. Although, the better the tools (and knowledge how to use it), the better the repair.

Thankfully my HP laptop powers on and works but the only issue is the battery that is draining fast.
That Chip is Dual Channel DC/DC, Synchronous Controller...
😄😄😄 ur amazing 😘😘
Go through schematic of the board u will find the chip no. There 👍
If we have to find it, we need more info about MB 😉
Can I know what microscopic cam are you using
northridgefix.com/product/microscope-camera-bundle-1080-60fps-180x-lens-ring-adapter-2-barlow-lenses-0-5x-0-75x/
RT8249A/B/C. Not sure
Sir it may be logic controller ic
You need to look for mother number and IC number on the board is PU310 you probably have to find it with that information
cool
i asked this a dozen times:
why there is no link to the flir cam AND which model is it?
Find a micro usb flir camera for cheap. All you need is a Android mobile. That's enough
Its very cheap brother 🌝
