This video shows the repair of an XBOX One S console which has no power. It does have a good, working power supply (PSU) so what gives? Here we check the board over, find a 12v rail short and then go ahead to examine the components in the APU power supply circuit where we find an issue which is stopping our console from powering up.
The replacement MOSFETs required are Toshiba TPN8R903NL,LQ.

No body has ever made me feel so guilty about not hitting like or leaving a comment. I gain so much knowledge from these that anytime he ask for a like or comment I feel so obligated. Seriously thanks dude.
Thank you for explaining everything step by step, you are a good teacher...
I love details. Therefore I love your videos.
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
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.
There was a huge lightning storm yesterday and one bolt struck so loud and bright and ONLY my Xbox One S died. I have a TV, PS2, Modem, cable box, and Xbox One S on the same multi plug-in wall connector. The voltage is going through the cord but how do I test my internal power supply? And why do you think out of all things my Xbox was the only one that took the damage??
Thanks some good info too bad your in the UK i have a problem my xbox one s powers up then turns off any ideas if you have done a video could you point me to it thanks.
Hey there,
Thanks for your informative video on how fix the MOSFETs on Xbox One S.
I am having the issue where my Xbox One S Starts with a Chime and within a second Goes off with chime.
I tried to investigate the problem and check for faulty devices such as Hard drive, Fan, Disc Drive, or even the Thermal Paste.
Nothing was wrong, I even changed the thermal paste on the CPU.
Funny thing is that, my Xbox One S will start and work as if nothing is wrong after every 4 days.
I know it's the MOSFETs which causing this issue, not checked the readings yet.
But want to know, why after 4 days my Xbox will start and i can play games upto how many hours I want, I played for straight 12 hrs, switched it off.
Tried to swtich if on immediately, stuck in the on / off loop again .
Please advice.
Love the vid! I always learn from your videos. Congrats on the channel growth too! Just had one with this exact problem yesterday.
Lol you learn from him, and I learn from you man 😂
Love the support TronicsFix gives
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.
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 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 :)
Hey, do you know where i can get the Mosfets from?
Nikesh Gupta What is a pwm controller? Is that what controls the fan speed?
@@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
I replaced the mosfet blew again
Pwm controller what's that
This is the video I've been adventuring far n wipe on TH-cam for and finnaly...turns out my dad has watched it and will get to it soon🤣😂
Thank you andrew. Just got my One S working thanks to this.
I received a water damaged xbox, your video was the first one. Found the problem immediately. Thank you so much!!!! You're the shit!!!
Practical, fast and objective! That's why I love this channel! Thank you for passing your knowledge!
If the mosfet is not faulty, what else should I check? there is a schematic diagram of the xbox one s
This guide helped me fix an Xbox One S I bought on ebay, thanks for making 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?
Did you find out? Is it the orange ring ?
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 😃
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. ;)
My Xbox turns on the light turns on and beeps and turns back off I have tested all the mosfets and they all are fine does anyone know what the problem could be and also I think I broke the the buttons for eject and bind could that be the problem
I have the same issue. Never found a fix. Did you?
Seems like it’s a serious motherboard issue as I have the same problem and never solved it all the “experts” don’t reply, don’t think anyone’s found a fix yet
Sounds like a timer ic fault
The south bridge can cause power issues so may need a replacement
I have the same issue
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 dont watch TV. I watch these videos.
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?
TPN8R903NL Is This Part Andrew?
Thanks for that!
how amdrew i have x box one s water damage powers on 2 sec turns off dry it out use ipa over boad dry water of it will i need put thomel past on it can help
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.
Can anyone offer some help? I have a xbox one with no chime or fan spin, completely dead. Used known good power brick and mosfets are good.
I followed his process here and I fixed the same issue in twenty minutes thanks for posting great videos
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?
You are the best and you know it!!!! I fixed mine 1 hour ago same mosfet same lane. Thank you mate.
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?
Check your rf board.
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
My Xbox one went in to repair the board. Yet my 360 is still working !!
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.
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.
Great video! Do you have a list of the part numbers you use? I need to replace one my MOSFETs and want to be sure I'm using the right one.
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!
How much did the fix cost, pls tell.
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?
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.
What is that chip called that you replaced?
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
I had xbox one sitting dead for some time. I knew where to look but didnt know how to test. This video showed everything I need to know. Thanks!
I have a quick question. I have an Xbox S with no power. There was a short I found and the Mosfet was bad. I replaced it and I can turn the console on, with a white light but it shuts off in about 1 second. I checked the power supply and it reads 12 volts. Does anyone have any ideas for places to check on the motherboard? Thanks a lot!
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..
Hi Andrew. Just watched your video on the xbox one 3 phase check. Really informative and I've checked mine, seem to be good. The issue I have is I turn on the xbox, powers up, beeps twice, fan turns about 8th of a turn then it just powers off. I've put a new power supply in it but have the same issue. Any ideas or suggestions greatly appreciated. Tried all the forums etc but no good. Thanks
Great job Andrew, keep the hard work... I subscribed 👍
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.
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!
what a awesome explained video.. thank you Andrew..
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 👍
Could this be my problem on my Xbox if the fan just twitches then turns off
Hey Andrew, i have measured the MOSFET Gates to GND and they all seem fine. Do you know what else could be the cause for my console not working?
Maybe the APU or some of the capacitors
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!
When I measure the voltage on the MOSFETs on my Xbox One Slim, I'm not getting any reading at all. I'm using an ETEKCITY Measure Up MSR-R500. I also placed it on the "diode" setting. Am I doing something wrong, or what type of Multimeter should I be using and what exact setting and range does it need to have to measure the voltage on these MOSFETs? Anyone's assistance would be greatly appreciated. Cheers!
I had the exact component fail, the Q9D4. I replaced the mosfet and sure enough, the fan twitched and the console booted. But after using the xbox for like 30 mins, it shutoff all of a sudden and upon inspection, I found that the Q9D4 mosfet failed. I tested it when I installed and there was no short on the board and after it failed, there is. I replaced it again with a good mosfet and the short in the power supply pins between 12v and gnd is gone. But I get continuity between V_CPUCORE and GND and V_GFXCORE and GND. Interesting to note that there is no short between GND and V_12V just above the power connector. Any idea how to troubleshoot this? Thanks!
I have a problem...i was scammed and bought a xone s with unknown liquid damage... Ale 3 supplies for apu is getting only 0,004v... So it should be cauesd by shortage, shouldnt it? I tried to clear it with isopropyl alcohol but it didnt help... Any suggestion?
@Andrew Paul, I have a similar problem, however my console beeps on, but then swithes off right after that, I got a multimeter and tested the MOSFETs, and I got a reading between 636 & 640, nothing more then that, but when I switch the probes (red on gate and black on the resistor) then I don't get any reading.
I have been sitting with this issue for months and I just can't seem to find the issue, I tried asking other youtubers about this, but unfortunately no reply from anyone. So if you could help me I would really appreciate it...
Chip power management MOSFET TPN8R903NL for Xbox One S I believe that this might be the msfet that you replaced.
I often come across power on off issues.
Check pcb power board fine,
Check power rails for short, fine,
Checked all mosfets on the board I can find nr cr40. The 2 mosfets nr the last power rail located between E and F No issues. Checked apu and reapplied thermal paste.
I'm just unsure as to what's wrong and cant find any videos to help.
I have 2 mosfets testing 734, while the middle mosfet is reading 063.
None of the numbers I'm getting match any other video of people trying to troubleshoot these.
This makes me think that I am simply doing something wrong but I have no idea what.
When I reverse the leads I get OL on the two side ones and the same 063 reading on the middle mosfet.
Pulling my hair out, please help.
Wow I had the exact same issue as you, and got this system working. Customer spilled apple juice on their console.
Same for me, there was something spelled inside the Xbox. Now I just have to find that replacement parts here in Germany ;)
Those capacitors adjacent to the MOSFETs , 6 820uf 2.5 v, are you reading a short circuit across them, when the Xbox is working?
I changed out the mosfet, the 12v rail is NOT shorting, but the mosfet I replaced is only showing .46v. Not 1.9
Great work, I also have an Xbox one s.. All voltage rails are present but After I test some components... 3.3V dissappears
Dude when i Tried this it sparked then I woke up surrounded by Orange Little & Big Sonic The HedgeHogs trying to force feed me Sonics Frito Chilli Pies & Strawberry Hot Milk I Had to drink the Milk then I woke up and Arse was bleeding what did you have me do Mate I thought you was my Best friend brah
TPN8R903NL,LQ(S N-Channel MOSFET, 37 A, 30 V U-MOSVIII-H, 8-Pin TSON Toshiba( from rs components)
I suppose its worth a try....I have an Xbox one s. I damaged a capacitor on the rf board "long story" and im wondering of one of my tech friends here could maybe help me out. On the back side of the board...c78 smd capacitor. I just need to know the value of that capacitor pls. My son would greatly appreciate it lol.
Q9D4 looks burnt on top :D could be just bad lighting.Nice video thank you...
I am testing the same thing on a regular xbox one motherboard, all the mosfets are apparently okay, but when I test voltage the mosfets are only receiving/outputting 0.2V!
Any clues what the problem might be?
Hi Paul I’ve checked all mosfets, capacitors, resistors, power supply, and hard drive on the board but it still won’t turn on I had it working 24 hours earlier when I refitted a capacitor that had come off I had it working for 3 hours now it won’t come back on please help
do you still reply? I have original xbox since dec. 2015. never a problem. left the house one day come back and it won't turn on. it makes an audible noise like it's trying to turn on but cuts short. eerily similar to a car trying to turn over but won't. orange light constant on power supply, never had water or any kind of damage.
I had a 12v short on my Xbox and found the MOSFET Q9e2 was bad thanks to your video but after changing it the unit does beep and turn on now but no white led or fan spin. Any ideas?
So the left 3 contacts on mine do not beep and read about 1.19 on the meter, the right 3 beep then count down to 0.00... This is already beyond my expertise, so I suppose I need to make a decision on selling for parts or trying to fix... LOL
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.
So when I test with black probe on gate and red on resistor the center mosfet reads zero the outside 2 are good,but when I flip leads with red on gate I get no readings across all the mosfet. Should the center mosfet still be the culprit?
Mine has an issue where it has power,will boot but no fan and shuts off after about 5 seconds.Plus I just realized this won't work for me being I have apparently a newer model that only has two blue caps,not as many as shown here.Bummer
Question all three of my mosfets were reading bad had no power problem. Checked everything like you did had a short to ground in the power supply plug on the motherboard changed all mosfets and now reads right and no short to ground anymore when I plug my power cord into the power supply the fan turns now but still won't power on whay to check next?
Thanks so much i followed every instruction perfectly it really works i so happy thanks again
Hey all. New to this. But this video was great for me as well. The one thing I am looking for is parts to replace on the board and what is the best route to go. My daughter's cat figure the Xbox one s all digital edition was better then a litter box and of course that went over good. I'm not sure how to post a picture on here and would love any advice anyone can give me.
please,,i need your help,,i tryed to mail you but i cant,,im from mexico,, i hope you have no problems with that,,bless-
What is the value of the capacitors for the 12v rail (the first 3) I think that is my problem. Thanks!
Someone plz explain why every video I watch these chips come off with little to no effort then when I do it they don't fuccing move, ends up breaking the chip every God dam time
I couldn’t under stand very well, what did you pour on it?
Flux
I have an issue with my Xbox one where I have no power on the faceplate but the fan is pulsing, when testing I find that there is a vintage on the fan supply that pulses in time with the fan. But I’m stuck on what components to check? Could this be a short?
Mine will power on for up to 5 mins after I replaced the PSU but usually it just powers straight off. Hoping this is the issue and not something worse.
My gates measure black on gate to red on resistor 625 but if i flip it around it doesnt show anything i am useing a cheap hypertough ohmmeter on diode mode is this shorted cause it reads 625 on black on gate to red on resistor but it doesnt show anything the other way? Do i need to save for a better ohm meter??
I'm getting the light turning on fir like a second...than turns right off. Ive tried unplugging cable, pressing the buttons to reset and nothing....thoughts or same issue?
Hi Andrew I got the same problem but it's with my Xbox One X. Do you have a video for it?
What if u have a beep. But it cuts off. Then what. I replaced the power supply unit and the same results. It beeps but cuts off immediately.
sir i have xbox one s .its hdmi port is ok hdmi coils is ok hdmi retimer ic is ok but its not showing display joystick controller is connecting and i can see optical light on backside also .hdd changed but no display ,same hdmi ic from this mobo is working on other mobo .any solutio sir ?
Hi Andrew, I got a new power supply but looks like it is not fitting in the socket properly, can let me know how to do it, I sure, it cant be that loose. Thanks!
would you say if i have the same device powers on but then turns off after a few seconds. fam doesn’t spin. you think i should replace the supply?
What if i'm not getting anything from the first 2 and only .002 from the 3rd? They all blown?
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
I have one 100% dead. checked those mosfets and good, I do not get a 100% short just a beep at first then meter goes up switch the leads and same beep at first then meter goes up.
My xbox one x has a good power supply and nothing happens when I hit the power button. Also my other one x turns on then turns off after 10 seconds.
I've been an idiot and thought I needed to add solder to the pad. Now I have like a lump of solder on one the middle of the pad thats I cant melt with my iron. Will a wick soak it up?
Hi i have a xbox one s no power tryed good power supply checked for short on 12 volt rail and is not short any ideas were i can test from here ? Thanks
