8 months ago i lost my xbox 1. I quickly replaced tee power supply with a new one but the console did not turn on. I got a donner xbox 1s from a friend. Today i found ur video armed with a multimeter and your video, tested all 3 regulators. 1 was faulty. I replaced the faulty one and the xbox worked. Thanks a million brother. Very precise tutorial and to the point.
I very rarely leave comments, but I had to comment on this. This video helped me tremendously and I was able to get my nephew's xbox for him running again. I learned a lot from this, and wanted to say thank you.
Amazing video. I watched it and believe it or not the Xbox I bought had an identical issue. Another commenter put the link on for the replacement chips, I got 30 for £5 next day delivery. Used my dads hot air rework tool. Repaired entirely from chips arriving (ok motherboard was already out) to running in less than 5 minutes. Thank you so much. You’re awesome. Keep up the good work.
Duuuuuuude, this video was spot on to my problem. I thought I was going crazy - every video was how to fix the power supply, but I knew the power supply was good.
Love the video!! I'm very new to fixing consoles but I really want to continue my father's legacy. hopefully I can watch more useful tutorials from you in the future. ;)
Ive been clueless on what is wrong with my Xbox, this video has really helped! Unfortunately the next chip along from the middle is also showing no signs of life so will have to replace it too. But now i know how to fix it, i was contemplating on selling it as parts but you motivated me to keep going. Thank you!
Cheers sir. Always like to check out your videos. Had a One S a while back with no power that got left with me. Will need to try this out in the morning and see how it goes. Thanks for your knowledge!
Your videos are simply the best, I am starting to micro solder myself and am working on game consoles as my daily job. Thank you for all of your instructional videos.
First of all thanks for a straigh to point amazing video. I would like to mention though as a compliment, you would make a great football comentator, honestly. You have a football comentator voice mate, natural. I enjoy listening to you :-)
Thank you for posting this particular method of troubleshooting MOSFETs in circuit... I have a DUAL processor Xeon system with 6 phases for each CPU, and 2 MOSFETS per phase (total of 24 MOSFETS). I tried several different tests, but YOUR method enabled me to identify the exact MOSFET causing a short to ground. In hindsight, this is the most sensible test, because it exploits the basic theory behind a properly functioning FET.
Ordered 9 of these mosfets just after watching this video for a repair I have coming in tomorrow, cheap enough so if the XBOX One S that I am receiving tomorrow isn't fixed with these then it's no big loss. Thanks for making these videos. Edit: turns out it was not one of the mosfets, 12V to ground short stayed even with removing all 3, most likely a Southbridge or APU issue which now isn't really worth fixing.
Hey Andrew nice video , i have fixed some of these where the mosfet would blow again so i would change the PWM controller too and it would sort it out :)
@@larsltz1326 cgi.ebay.nl/ws/eBayISAPI.dll?ViewItem&item=153166508040 It would be better if we could find these at digikey or farnell, but no luck so far
5 years later this helped me figure out what was wrong with my Xbox One S. Bought it for cheap, verified 12v on the PSU and I was stumped after that. They (now, at least) sell the MOSFETs separate so you don't need a donor console.
Excellent video, thank you very much, Andrew. Got a console in with the same issue - one of these mosfets blew (lane to the right of the one in the video) and took one of the capacitors with it. I'd had not been able to identify the issue without your video! My hot air station doesn't seem to have enough power/airflow to remove the current one, so I've ordered something with a bit more grunt. Fingers crossed the surge hasn't taken anything else with it, as I've never worked with larger surface mount chips before. Wish me luck!
Impressive skill level and professional demeanor. I hope my x box one lasts. The only Microsoft console thats lasted more than three years is the original x box and that has a failed clock capacitor. I wish I could diagnose and repair to this level. I usually just buy another console or swap boards...Best Wishes
Great Video Andrew, had short on 12 volt Q932, you have no doubt found the device by now but if not it is a TPN8R903NL DigiKey and other have stock. Thanks.
Nice explanation matey. I've got a gtx 980m and I think the mosfets gone. I get my multimeter tommorrow and had no idea what to look for, before now that is....Thumbs up.
Wonderful video! Rarely leave comments but I wanted to do so to express my thanks. I haven't yet tackled my troublesome Xbox but I would like to know what kit you recommend to get me up and running in the world of electronic repairs? Many thanks!
I fixed it the center mosfet I replaced first then they took it home then it blew the fet toward the back of machine changed it and it worked. Satisfied customer. The pdm or whatever was not the problem
@@AndrewPaul isit possible to give me the value of the mosfet so that i can buy. The problem on mine is that when you press power button it will light up for a sec and goes off. Thanks Andrew
Thanks for this video it’s awesome. I’m a qualified electrician and I have just diagnosed a faulty mosfet, credit to you. So I am going to attempt this repair. If this repair doesn’t work do you have any other suggestions that may help. And would I get away with a heat gun? It’s got 3 settings but it’s not precise.
Genius love your channel I know nothing about this subject but I find it so intresting thanks for great uploads God I wish is sent my Xbox to you instead off throwing it thumbs up
Great Video, love watching these. :-) Also in case you missed it i did reply to your email re the Ultimaker board and sent a couple of photos attached. Thank you.
nice diagnostic, those mosfet very common to broken on xbox one, still don't understand why they choose tiny mosfet for High side FET. I usually replaced those mosfet with similar specs either From Onsemi or AON
Excellent video! I narrowed down my no power issue thanks to this. I have a board with a blown IC labeled Q9E1 just to the left of the MOSFET that you replaced (6:40). I'm guessing it's a 12V regulator or some other FET? I also get a short across the MOSFET gate so I'll be replacing that as well. Do you think it would be worth while replacing the PWM controller while I've got it on the operating table or would I be pushing my luck going after all 3 at once? I've replaced plenty of chips that size and smaller, my hands are pretty steady, but I know some are prone to pads lifting more so than others. Easy on the heat I guess... haha
Hey, have similar issue with these IC that you mentioned.. did you replaced it? Did it helped? because I have shorts on all three of these IC and all the capacitors behind them and below the main chip.. not sure if only these IC's are affected or the main chip is damaged as well..
Nice repair Andrew. How did you know where to start looking for the short? Or how would you go about finding it with no prior knowledge of common shorts on these fets, or knowledge of the 3 separate "phases"
It can be difficult to trace circuits just by following the traces on the board; what helps me is understanding a bit about the high-level function blocks of a circuit or board (power, video, radios, controllers, CPU/memory) and the parts that you find in each. The easy (unhelpful) answer is experience, which is true but doesn't help someone starting out. Every subsystem needs power and there's a definite order in which the subsystems get power and start up (e.g. video & wifi will come up after the CPU). You get clues by the overall system behavior (does the fan spin? do you get lights on the board?) which helps isolate the high-level functions which aren't working so you check them and their dependencies. Hopefully this lets you isolate the possible failures to a few sections of the board and you can do a visual inspection for burnt/abused components before you start probing pins. Look for obvious problems; what's obvious to you will come with experience but everyone starts at the beginning and there's no substitute for getting your hands dirty :) There's a lot of detail to take in but that's why I watch people like Andrew & Louis Rossman. It's partly to pick up on their experience with specific hardware but mostly to understand the logic they use when diagnosing problems.
Thanks for the excellent videos, I love watching and learning at the same time, but could you please let me know what flux you use? And a good soldier for hdmi replacements and other pcb work. Hope to hear from you.
Great video, very informative. I have an Xbox One S that powers on for a few seconds and then powers off again do you think this would also be a bad Mosfet as in this video?
I have this same problem and also happen to think it may be a bad mosfet on the my Xbox one S but have never used a multimeter or have any knowledge of what the functions are on them and I want to thank you for the instructional knowledge on what settings to use on a multimeter as well as the repair I also repair consoles for a local gaming shop called east coast gamers or website is www.eastcoastgamersnj.com feel free to check it out. Thanks again andrew 😃
I'm learning and inspired soo much from yourself, tronixfix and my mate vince I've actually invested in gear I. E solder station, helping hand, Multimeter etc that I've decided to take on a mini project myself, a neighbours a xbox one (original) with a simular issue. Thought I might of be the power brick but the capacitors looked OK, the xbox board on the otherhand different story Apu maybe fried due to very little thermal paste left on it. Maybe a gonna Will test mosfets
An APU isn't going to fry due to lack of thermal compound. Modern CPU's/APUs/GPUs are all really good with thermal throttling or just shutting down in extreme cases.
Hey Andrew, great video as always. I've got a similar issue with a console that turns on and then off immediately. Supposedly, it's nearly brand new (less than 2 weeks old). Power supply is good. The 3 mosfets are each reading .65 one direction and then OL the other direction. Any thoughts for where to go from there?
@Andrew paul where do you buy these chips from? I see RS Components do an alternative as others have suggested, I see your in west yorkshire, I'm from Huddersfield. Love the video, I was about to bin my xbox after reading forum and using youtube on how to fix this and none of them went down this route, I thought I had a bad power brick until I tested it and it was fine. This was just a recommended video, alas.... youtube has actully recommended a useful video.
Another great video, best one out there in regards to board level power issues. I currently have a motherboard with a fault on the PMIC GASAS1640, have you done any videos that relate to this? My problem is that pin 1 trace for whatever reason is gone, how would you repair something like that?
Only just stumbled across your channel Paul fantastic in-depth walk through very easy to follow 👍 I know it’s an old vid but I’ve got the same issue which I’m waiting for parts on but I have a probelm with a couple of components next door to the Q9B3 on the V GFX CORE side . Basically the components are missing for C9D17 (a cap ) and R9D30(resistor ) these were corroded and have since gone missing . You don’t happen to the know the values of the missing components do you I’ve search all over the web and the closest I’ve come is apparently the resistor is a 124.4K 🤷🏻♂️ Any ideas thank you 👍
Hello Andrew, great video!. I have a similar problem on my XBox One S, but in my case there is no sound at all when powering it on. I checked if there is a short on the power pins, but there isn't. I also check all three of the mosfets, but they seem to be fine as well. I just found that all the capacitors under the APU are shorted, so I think in this intance the problem is the APU itself, right?
You'd need to work it out as a percentage in relation to the max airflow on your particular machine. So for example if your machine has a max flow rate of 130l/min, you'd do (110/130)*100. In that example you'd set it to around 85%.
My machine has a maximum flow rate of 120l/min. Unless your machine has the same max output then your percentage and mine will differ for the same resultant airflow. On my machine 110l/min would be approximately 92%.
Love all your videos. You are my last and first stop when I am stumped. So if a system has good power supply and no short to ground that would normally be the power controll IC? Just looking for a starting point for testing.
Is there a way to test the internal power supply without taking it apart? When I plug in the power cable there is a click (spark) but I cannot see any fan movement. Would the console still charge a usb device if it had a defective part other than the power supply... Do you know what the voltage should read if I remove the power supply, plug it into the mains and use a multimeter
power supply should give 12V. If there's a short on the APU power rail, it will likely trip the overcurrent protection on the PSU and cause it to shut down. As for the click sound, I'm guessing that would be the overcurrent protection kicking in. Mine did the same thing until replacing the faulty power rail mosfet on my One S board.
Hi, firstly brilliant video. I have a problem where Xbox One S starts and switches off after 6 seconds. I have tested the first FET (furthest left) and this appears to not give a reading on either probe arrangement. also has continuity to ground on that 1st pin. If I change this FET should the fault disappear or would you have thought this is caused by APU or a more serious fault. Thanks
Hey Paul! I learn soooo much from your videos! I have a question though. Someone gave me an xbox one s board with a missing NAND chip. Is this replaceable or would I have to flash it.
When he is sticking the probs into the power supply plug, where is the other prob? and if my voltmeter reads 8.87 when the black prob is on the small diod and the red is on the fuze thing is that dead?
Hi Andrew, excellent videos. I have the beeps once and turns off problem on the xbox one s. The LED doesn't light but there is some power going in albeit briefly. I've checked everything you point on this and cant find an issue. Any idea where I should look now? I'm stuck. Thanks in advance.
Hey! Great vid. Fixed my console thanks to you. Bought another with a busted mainboard, but that one seems to short only for a certain amount of time, then stops. To find the continuity again i need to switch the probes. Any idea where to look for the short??
Was wondering how u get heat sink off from board to check the MOSFETs. Not sure if u need to use a heat gun too loosen adhesive it looks like is underneath it not sure

Hello sir, what a magnificent video. I need to ask probably a dumb question when you check the MOSFETs do you have power to the board? If so how?
No - you don't need power applied to the board.
Thank you so much. My main general question is why on earth did this "gate" go wrong in the first place? Heat? excessive use? or what?

You'd need to work it out as a percentage in relation to the max airflow on your particular machine. So for example if your machine has a max flow rate of 130l/min, you'd do (110/130)*100. In that example you'd set it to around 85%.

My machine has a maximum flow rate of 120l/min. Unless your machine has the same max output then your percentage and mine will differ for the same resultant airflow. On my machine 110l/min would be approximately 92%.
Thanks for this video. If it wasn't for this I wouldn't have noticed that I dont have mosfets
thanks, i repair my xbox with this video, from chile
Thanks again
. Your video is very helpful.
Hi, Andrew, I like the video it's helpful, but please what the name of that small part you replaced?
Part number etc is in the video description.
Love all your videos. You are my last and first stop when I am stumped. So if a system has good power supply and no short to ground that would normally be the power controll IC? Just looking for a starting point for testing.
Is there a way to test the internal power supply without taking it apart? When I plug in the power cable there is a click (spark) but I cannot see any fan movement. Would the console still charge a usb device if it had a defective part other than the power supply... Do you know what the voltage should read if I remove the power supply, plug it into the mains and use a multimeter
power supply should give 12V. If there's a short on the APU power rail, it will likely trip the overcurrent protection on the PSU and cause it to shut down. As for the click sound, I'm guessing that would be the overcurrent protection kicking in. Mine did the same thing until replacing the faulty power rail mosfet on my One S board.
Nobbs66 is that part in the video
i’m having the same issue with the same chip but it seems like the solder won’t melt, i’m using an airwand like you at 490 C°. can anyone help?
Did you find the solution?
@@TRVlogger no not yet, i’m still looking around
Hi, firstly brilliant video.
I have a problem where Xbox One S starts and switches off after 6 seconds.
I have tested the first FET (furthest left) and this appears to not give a reading on either probe arrangement. also has continuity to ground on that 1st pin.
If I change this FET should the fault disappear or would you have thought this is caused by APU or a more serious fault.
Thanks
Hey Paul! I learn soooo much from your videos! I have a question though. Someone gave me an xbox one s board with a missing NAND chip. Is this replaceable or would I have to flash it.
Loving the videos what is the mosfet you replaced please
When he is sticking the probs into the power supply plug, where is the other prob? and if my voltmeter reads 8.87 when the black prob is on the small diod and the red is on the fuze thing is that dead?
Did you find out? Is it the orange ring ?
Hi Andrew, excellent videos. I have the beeps once and turns off problem on the xbox one s. The LED doesn't light but there is some power going in albeit briefly. I've checked everything you point on this and cant find an issue. Any idea where I should look now? I'm stuck. Thanks in advance.
Excellent video Top man
I have power after this.. but now my light will only turn on for 5-10 seconds then shut off. Why?
Is your fan working?
Hey! Great vid. Fixed my console thanks to you. Bought another with a busted mainboard, but that one seems to short only for a certain amount of time, then stops. To find the continuity again i need to switch the probes. Any idea where to look for the short??
thanks man same problem but the mosfet from where i can get it im from another country is aliexpress or amazon can get it from?
Cheers for the info x
Nice vid, very informative.
Those capacitors adjacent to the MOSFETs , 6 820uf 2.5 v, are you reading a short circuit across them, when the Xbox is working?
Chip power management MOSFET TPN8R903NL for Xbox One S I believe that this might be the msfet that you replaced.
Andrew, I have 12v on the test point and no short in power rail, but it won’t power up at all. No fan twitch even! Any suggestions?
Was wondering how u get heat sink off from board to check the MOSFETs. Not sure if u need to use a heat gun too loosen adhesive it looks like is underneath it not sure
Great repair!
