Hello Alex! I’m happy to say I just did my first successful PS5 HDMI repair this week! It even had a torn trace! I could not have done it without you and your videos so I would like to thank you. If I would like to continue in this direction, professionally, do you have any advice? The shop I currently work for does these kinds of repairs but does not focus on them solely. Thank you again and I look forward to every one of your videos!
Hello Rafael, My name is Pascal, if I may, I would like to congratulate you on your successful repairs. However, how do you expect anyone to advise you to continue on your path of work if they don’t really know you, like a parent knows their child?.. The only advice a professional like Alex can give should be related to the genius that you find in yourself.. The best example, is when Alex himself learned from, during a sales course while he was working as a car salesman, and applied that knowledge to service customers in a completely different field.. So If I may, enumerate step by step what we all should do, to find and to Excell in our genius, that would be it.. -1- get a diploma in what you like to work, Alex is an engineer. ( it’s important because if one wire is in the wrong spot, more damage can be caused. Right? -2- the more hours you put in the work you like, the more you become a master. Look at the example with Alex, he’s not only excellent at hardware engineering but also became good at TH-cam video making, explaining in detail step by step (teaching), providing information on tools and how to get them, teaching how to respect our work, our customers, our family, our colleges, instruments…. -3- it’s excellent to learn from videos, and remember that we can also learn from any other experience, wether it’s a good experience (to repeat) or a negative experience (to avoid) -4- we should always try to master more than one thing, (keep our mind open to other opportunities) take Alex as example, he’s amazing at what he does, however, if he did only one thing he would’ve been known in his town and most probably happy and satisfied, but because he created the TH-cam channel and retailing related products and being a good teacher.. many other doors opened in his path. I hope I was able to get you to see the bigger picture. Always remember.. many like you and me, look up to people like Alex. I wish you many more successful repairs and a happy future. I hope Alex gets a moment to add or correct us. Thank you Pascal.
@@froydenzi True. You could remove the bios chip, reflash it in programmer, and replace, as last resort. It's a soldered CPU. Just guess, because there no short.
The mosfet that flew away most probably drank a bit too much of Red Bull. I hate when nearby components fly when I get a bit overconfident with the air speed. Great job and great video as always, keep it up!!!
For people starting out it would be useful to have a video showing how to change various types of components. This could be made by editing parts of of several videos into one, if anyone can find the time. Titles can be added to the chapters to make it easier to find the one you need. At the moment I am in physio rehab where they keep me busy. I am still working part time.
Can you replace all the "drmos's" with high quality ones and replace the dead processor to arrive at operational board? Are new parts available? Cost if feasible?
Wow you did excellent job at your repair work, that’s what I’m motivated Learn n watch your video and other repair guys on video too,, y’all are amazing… god bless.
I love watching Alex fixing stuffs but this time was too obvius that the cpu was the problem since the cpu its not a voltage distribuitor but a processor wich means that cpu receipts low voltage but hight current and that is why cpu blowed up those coils and mosfet. Sure that if you change the mosfet the short will probably go but cpu its already dead.
I had the same thought. Looking at all the scorch marks around those inductors, I was looking at it and thinking: "Wow, looks like some serious voltage went through there all the way to the CPU." When he found the short, I still wondered if it was actually going to power up.
I have a similar issue with same laptop... Inductor look cooked mosfet next to it is suspect solder joints on mosfet next to cooked inductor look poor and somemissing... I flux and reflowed it....( as I don't have replacement ) just to see what do.... til legs look all there and shinny.. It works better but still issue... Original problem is blue screen once heats up after an hour of use then will only work 1-5 min before bluescreen loop......til cool down.. few hours... Now it will work for a few hours and will only blue screen once maybe every 6-8 hours or so.... Maybe if I can find a mofet for it ( for cheap ) I will try... replace see what it do...
Hello. Yes, income and inflation are not compatible here. Inflation is high. I am a servant of Iran. I receive a salary of $ 400 a month. What about you
Can you please help if you have seen same issue with this model? The adapter has the green light is lit. When I connect to laptop, the adapter light is "still" lit. But on the power button it keeps cycling blue, purple and red (red stay longer than other colors). The laptop doesn't turn on. I have tried battery removal and pressed power button for 30s, still the same issue. Everybody thread and the videos you have talk about adapter turning off. But that's the case for me. Can anybody please nudge me in the right direction ?
The fact that just one component can render a board a no fix is proof of the electronic waste we see in the industry! Not having the right to repair and unable to get schematics and replacement parts is at the core of this problem and it needs to be addressed and fixed! The waste is uncalled for and I would love to know where all these people that claim they are for saving the planet are? They sure as hell are no where to be found on this simple to fix problem, where all that needs to be done is these manufacturers need to release their hardware diagrams and parts lists so we can fix these otherwise good electronics that because they are hording the information and hardware needed our landfills are full of electronic waste that is leaching into our eco systems and polluting our land and all because of a companies greed!
I have one of those short killers and I have a few shorted devices. I've checked components for shorts, found caps shorted but when I inject voltage to the shorted caps it always sparks and doesn't inject voltage (I followed the traces and it isn't ground that I'm injecting). Is the device faulty or am I doing something wrong? It's happening on all the boards with shorts that I'm practicing on.
i think in this case, cpu kill the mosfet. the mosfet its just a pass for the voltage and current and they just fail in two ways....short or open and the sacrifice then selves for the cpu when shorted.
Volume and power constrains, but also pricing most of the time, laptops are a volume market with low margins, desktops (specially made from parts) have a little more segmentation. I've run a custom xeon rig with rampage V and a 1080 Ti Lightning Z almost 24/7 for around 4 years, 0 problems. I just pick the most overbuild parts every time i update, because the price is paying for over-spec redundant components that will last me a while. In contrats evert high end laptops that i've own, always something goes wrong in a couple of years (battery, charging circuit, gpu died, etc) , and then you flush all that money in the toilet.
Dear Alex, thanks for this and all videos that you share your knowledge with us. I will be happy if you could answer my question about my MSI GT72S 6QD. There is a light when I plugged in but my PC doesn't turn on. The computer shop told me that is faulty Mobo. There is no repair shop here. Did you repair any kind of this problem? Could you share the link of your video if you have. Maybe I can repair it myself because you are living far away from me.
Alienware (Dell) made a downgrade with that Laptops. I have a M17 R3 still here and on that Model the CPU is placed into a socket like on a normal Mainboard. So you can simply change it. Same goes for the Graphic card. If they would change that back so you can replace the cpu if its faulty, then alot of trash can be saved
problem lies with the cpu manufactures they used to make laptop cpu's that used a socket. now they're all made to solder on a board i used to repair laptops up to 6th gen intel arround 6th gen intel i saw most companies change to soldered cpu's i have a lenovo y510p in for new thermal paste and a clean up cause it overheats 4th gen i7 in a socket its to expensive and takes up to much space in smaller laptops to put in a socket
Got an M18x R2 and really do wish they would make something like that again but pretty much fat chance especially the two mxm slots as everything is BGA shit meant to fail after a couple of years. The same goes for being able to use four 2.5 sata drives because some like having data and not subsisting off a single low capacity SSD.

@@Joe.o0 The CPU is soldered on the board, so it would be very difficult and would need special equipment. The older generations like 17 R3 had socketed CPUs and you could easily replace them.
I have the same Notebook my is shuting down when i install intel hd driver, i try change cpu and nvidia gpu but still same, i will check mosfet today, greetings from vienna
@@overnightdelivery Well, sure, but bad CPU is not necessarily the issue. Considered the cost of replacement, hoping it's good, and reballing and mounting, that should be last resort.
I honestly have no clue what you’re even talking about half the time but what you do is just so satisfying to watch. Keep up the good work

Yeah, but customers do not like that. Especially if they have to pay a fee for a no fix. I know how people think.

Why not use flux for part removal?
When you asked which mosfet is bad, I guessed the cpu is bad.
Reason is because multiple inductors have the same burnt/black appearance.

Would this motherboard be repaired if we had r2r?
He knows whats the problem and its economically not viable to repair this mb.
@@MartinRepairs I wonder whether its a brand name manufacturer that builds bad boards or the own did something they shouldn't have.
@@MartinRepairs Yes. Make the CPU and GPU chips replaceable (socketable). Soldering directly to the board is unnecessary.
I think the owner of this device wanted to overclock and the result is great
My x17 has 4 OC profiles in the bios. For XMP cpu and gpu. Not really any need to manually oc on the x line. Never had a m model.
Not necessarily. It could just need a bios flash, since with a soldered CPU, it's not like you can change it.

Regular desktop PC's rarely ever have their CPU's cooked by dying MOSFET. Laptop manufacturers just don't seem to care.
A lot comes down to the thin and hot meta where cooling is secondary to aesthetics never mind the component skimping.
