How to spot a faulty CPU - How do we know the CPU is even faulty? 

you made so many happy people world wide from teaching how to fix. No one can teach like you. you are the BEST

Thank you for supporting us with these useful lessons

Excellent sir as usual

Thermocamera is expensive. However very useful not only for CPU fault finding. If electronic repairman, electrician or HVAC technician can afford at least $350 worth thermocamera with 160p+ resolution, he must get it. I agree - alcohol under zooming lens or microscope is nice simple method. We used thermal paper from fax machines or cash terminal receipt rolls - overheated faulty components left nice dark rectangles :)

unbelievable. thank you for this fantastic tip.

Thanks Master Sorin...

Nice Video Dear Sorin!

Please do you have a detailed video on fixing the 3v & 5v power rail? Thanks!!

Very good video and informative

thank you, very useful video

Nice video, thank U 🙂

Great, i learn something new!

where did u place positive? on any legs of the coils? also what voltage u provide? like 1.5v enough to see short?

Good luck sir

hello mat excell video as usual . i have a question plz . i have lenovo was dead charged battery manually tested laptop came back on . one day after again all battery charged has eeen drained to ziro and now whatever i am trying to charge it manually (by bench power supply) it doesnt take any charge ?! is the battery dead or i did break it down you think ? thanks a lot

thxs milord!)

Good day! Tell please what Thermocamera do you use? And what microscope? Thank you

Amazing !!!

how to find which side of an inductor should i keep to get the reading and how to identify which power supply is for which chipset

You are amazing in the way that you describe, I have one question can we apply those methods on the GPU processor also ?

Have you got any videos showing how to set the power supply up? Please. I don't understand why it doesn't push take all the power you set it up for?

good idea

thanks sorin...

Please sir I need some set of tools list from u to start some chip level work. Plz list for me so I can buy them gradually. Thanks

I'm your number one fan

Thank you Sorin, i have a pga socket cpu, the problem is when i check the core coil and other components near they all beep with ground, but if i take out the cpu from the socket then there is no beep with the ground, can you please suggest what can be the problem there.

What thermal cam does he use?

Please what's is name of the camera u used

Good day master thanks for all you do for us sir🙏 the petrol oil you made use of is it ordinary petrol for cars & vehicle?

Recently i received two different brand PCs one an old msi with old nvidia graphics card and the other lenovo with no graphics but both have same issues power is on with fan spinning correctly but no display, am not particularly sure if this reach you but you are my pc maintenance guru can u help.

This video is seven months old, but I watch it now, but I have problem with cpu i5 6600k mounted on Asus Z 170k, both bought used on eBay. I can't install win 10 pro from usb stick, neither from SSD with previously installed Windows 10 pro, that work fine on old motherboard. Only get blue screen errors. I solved this problem with turn off all cores, set on only 1-3 cores and works fine. I tried everything setting changes in Bios hopefully to work with all cores but none. After so many tries my pc won't boot no beep, no post, only black screen, all fans and led on motherboard work. Probably my cpu is completely dead I don't know for sure. Now I ordered another used cpu i5 6500 from eBay, I hope it will work. I think the motherboard is ok..

01:07 the two phase on the left of the cpu is VCCGT they're for the intel graphics. Three on the right is Vcore, they're for cpu core. It has nothing to do with The Turbo Boost.

How to test the new ones with graphics included on the same chip?

Fantastic video and i see you bypass the mosfet and send power direct into the CPU but if the computer isnt on doing work and calculations, why is the CPU taking current and heating up? What is happening here?

Actually, I have a CPU not getting hot at all (tried with bensin) but is taking around 100 mA. Is this supposed to be normal?

wasn't this the last video.. or did I do the time warp dance and watch this yesterday but my comment and thumbs up vanished.. Well Sorin is the real deal no matter what..

I have Lenovo Ideapad L340-15IRH. It has i5-9300HF CPU (without integrated GPU) and GTX1050. At the all coils of CPU I have 2 ohms resitantce, as well as the same at the coils of nVidia GPU. Does it looks like a faulty CPU, doesn't it ?

Hello Sir, I have an asus x555ba laptop, the fan spins fast and the laptop always turns off about 1 minute after turning it on, what do you think the problem is? Thank you

reball the cpu it will work. cpu die rarely fails. my number 1 suspect is solder balls underneath the cpu.

Is the CPU always dead when you see a shot spot? Have a laptop with Ryzen 7 5800H cpu, all power rails ok, but no display. CPU getting hot, GPU warm (RTX 3060). Checked with thermal cam and see a hotspot in one corner of die.

Buna ziua, la un laptop Fujitsu , i7 a 6 generație, pe prima faza sunt 1,2 ohmi, pe a 2 faza sunt 2,2, e in scurt procesorul?

I wish this time you try with diode test mode 😢

For what reason the CPU cannot be replaced? Because it is soldered on the motherboard? What if it has a ZIF connection?

I saw this video, it's dejavu

There is a spam using the name "ectronics" and putting your channel photo. Asking people to add in telegram in comments.

Isn't this video reposted? Mr Sorin.

If not where can we get the petrol?

The other day I was working inside of Premiere pro(in which my laptop was consuming Dedicated GPU), blue screen of error popped. VIDEO_TDR_FAILURE error. Tried: Clean installation of driver Clean installation of OS from Microsoft site Rolled back to Windows 10 and installed driver. Using DDU performed a clean installation of GPU drivers. Still code 43 persists: Windows has stopped this device as it reported problems (Code 43) Any fixes?

Again first one 😊🙏

😁

why repeat your video?🤯

Helpful, but still not a very accurate way.

bla bla bla , waste of time, mixed content

Nice
