XBOX One Light of Death - Bad MOSFET and power regulation circuitry - Diagnosis and Repair
HTML-код
- Опубликовано: 15 окт 2024
- This video covers the repair of an XBOX One games console with an issue where it powers on then off after around 1-2 seconds, otherwise known as the Light of Death.
In this instance it was caused by a blown N-Channel MOSFET, faulty power regulation circuitry (U9D4) and associated surface mount components.
In this video we cover the diagnosis of the faulty components, their replacement and final testing of the console post-repair.

Very nice to see people fixing things rather than throwing away. These companies should be made to help us fix our electrics
Nice work Andy, I had a power issues one that I had replace the Southbridge on and still no dice. Have just checked and I have the exact same issue as yourself but no visual damage apart from a tiny dot where it's started to burn! Thanks!
I love RUclips and all the smart people on it creating content. You great people have made me so smart.
I have an Xbox One here with the same exact issue on the same exact phase. Your video is a huge money saved! Thank you very much!
Awesome I miss real trouble shooting like this
This partially fixed my Xbox one issue, but it still shuts off at times. Good video! Keep it up.
I love watching and hearing you explain andrew very much , it's nice to hear how much temperature you put , flux etc etc welll explained and keep up the good work
my xbox does the same thing and i finally found some one who actually had a video that told me what is wrong with my xbox
It looks like the link to the
XBOX One Standby Voltages Diagram is no longer functioning. Great video as usual.
Excellent job on fixing an xbox one great job on going step-by-step I noticed 1 smalle little details with this video Number R9E2C9E4 seems to be missing
trying to diagnoise a xbox one with the same issue. now i followed the troubleshooting steps and got exactly the same readings on each phase. now whats the bigger looking mosftet? to the left on each phase? Now my suspicions are because when testing resistance out of the 4 phases (revised board). The bottom 3 pins closest to the left give me a reading of 0.104v. The fourth pin furthest to the right gives 1.570v. The other 3 phases on the same pins of what I "think" are mosfets are 0 apart the fourth pin closest to the right which are also 1.570v. Am I right in saying they're mosfets or something esle? and my readings correct? Thank you. Its 4:50am and I feel I've learnt alot from you as per usual! thank you
Hi Andrew, thanks for this great tutorial. Just a question for clarity please... It looks like the blob of solder underneath the larger chip that you replaced is spread out like a pancake and would short the pins along each side of the chip. Are those pins supposed to be apart or shorted? Thanks
Yes they are all connected to earth
I was cleaning my Xbox and fan with dust off and I stuck a paper clip in to hold fan in place idk why I did that but seen some people online say to do that... then when I went to power it on it just turns on and off now. It won’t stay on. The dust can did spray really cold. Do you think it froze something
I'm having a similar problem with an Xbox one S model. I found that the fet on one of the phases was shorted open and replaced it. Now, instead of the board being completely dead, I get the startup chime, then it goes dead again. I have tested all 3 phases and the one closest to the power plugin area reads .637 and then I turn the leads around and it reads 1.937 when testing the leg of the fet to the resistor, whereas the other 2 phases read .637 and 1.967. All other electrical components that I've tested look and read normal, so I'm at a bit of a loss as to what could be wrong. Any advice or can you point me to a forum where discussions like this take place?
hi man! the image with the power rails diagram isn't up anymore! can you please help me getting this diagram for the original xbox? I would highly appreciate it!
Great troubleshooting, observation and workmanship. I kinda do the same here at home as a hobby and enjoyed this video, as well the technique demonstrated. What causes this to happen overheating, bad fan heatsink, power surge, bad design?
Usually a power surge.
you are great your videos are great and have clear instructions as to what you are doing great job. you got my sub and a like :)
Many thanks mate :-)
Andrew Paul i have a question i have a xbox one s and it wont turn on i put my head next tobit and hear a buzzing noice can u tell me what to do
If it's a One S I'd assume it should still be within it's initial warranty? Get it sent into MS if so don't be tempted to go alone when you don't have to. If it's not however then the only way to tell would be to open it and inspect for any obvious damage i.e. burned components and try a good PSU if all else fails to see if that cures its ails. You're rather limited unfortunately without schematics for this kind of problem when nothing obvious is to be found.
I have an Xbox one original same to yours. I’ve looked everywhere and can’t find a single thing that looks bad. Used a thermal camera and only a few things light up. APU. Little bit of the chipset and the mosfets on the side (all normal apart from APU is hot in one corner. Not sure if that’s meant be like that?) my Xbox one is going white amber white amber (3 times as you said) and nothing else. Could this still be a chipset issue?
Ive had exactly this happen to me yesterday and im going to check in the morning to see if i can rectify this issue, cracking video and hopefully thanks
Nice video Andy ... my xbox did the same thing but i tossed it and got a new one after 2 people looked at it and had no clue what was wrong with it ..im sure this will help others with this problem ...keep the videos coming
Cheers mate.
I have one for the "strange" department: XBOX One, shuts down after 5 seconds if the internal HDD is connected. When it's not, it stays on. Tried with other HDDs, nothing. Different cable for the HDD, nothing. Any ideas? Thanks in advance!
Excellent Video! I accidentally dropped my XBOX One S and it will not power on since. No lights, no fan spinning, it is completely dead! I tried with a different power supply but no joy. Is there a particular place in the motherboard that i should check? Or is it completely toast? Thanks!
Andrew, any recommendation on fixing my Xbox One 500gb. I have the orange light on brick, bought two different bricks from amazon as that was the top problem from youtubers but did not work. Now, the machine does not light up in front. Any recommendations on what the prob would be or repairs shops in the US that could fix this.
I'm getting readings from all the caps raising from 120 ohm and up. What Could cause them all to be bad on all phases?
I have tge same xbox with the same problem but only thing nothing is burnt everything on the side you did in this video is good i was wondering if you woupd have an idea to what else i can do
Mine powers on fan dose not spin then shuts off. I did take it apart to check if anything was blocking the fan but nothing was. Got another fan same issue. Tried all the reset methods and still nothing. Nothing looks burnt like in your video. Also tried another power brick and same problem. Power brick is Orange when plugged into it. Then when I plug it in it does turn white. So power bricks are good. So I have know idea what's wrong. Any help?
Great video!!! Though, what if you have the light of death, but everything on your circuit board looks totally normal?
Hey Paul , great video as always. Seems like the link to the XBOX One Standby Voltages Diagram is no longer working.
Where do you buy replacement MOSFETs? Specifically the type you replaced in the video?
Mouser.com
Hi great video!! I have exact issue here, I’ve checked the components for a burnt one to replace but all seem to be working. Do you have any other solution for solving this issue please?
My Xbox one turns on then off after about 3 to 5 seconds. Changed the power brick and wasn't that any ideas? Didn't see anything unusual on the board.
would you take a look at my motherboard i turn it on it goes from orange to white for about a sec wont turn on all i get is bep and one spin of the fan
Bro please help!!!!!!!!!! I have 2 original Xbox one motherboards with me, I tested the C9F12 little chip thing (still new to this) and on one of the motherboards it shows OL and on the other 0.70! Both are defective but could the open loop one be the issue for one of them?!?!
Hi Andrew.
I have an xbox one S with the same problem but the serigraph is different to the mosfet of your video, since it is a one S. It is the component 4C50 (Q9D2) I do not locate the component. Do you know what your datasheet or name is?
Regards. Sergio
I have the same problem! Where to buy "4c50"?
Have you found anything?
Tell me andrew mine has orange light. When i push the switch on, i hear a beat sound from the speaker, the power supply light turns from Orange to GREEN and then the xbox one don't start, the front light of thre xbox one does not even has time to light. So from orange to green on power supply, very very quick green, a beap sound, no front light and does not turn on, There was a mosfet burn. I did replace it from eBay. I took the four first numbers on the mosfet and i did order it. I did put it in and same thing and the new mosfet was burned again, short with yhe little resistor at his up right(Gate short). What do tou think. All the capacitors near the mosfet, the big ones between the mosfet and the APU measure 7 or 8 ohms between them exept the 2 or 3 last ones measure like 98 ohm and all the little capacitors over the APU measure 7 ohm, all of them, almost. I had a short everywhere, i took the mosfet off, the short is gone exept all the big capacitors between coils and APU still measure the same 7,8 ohm. They are written 2.5 volts just to help you know which capacitors i'm talking about exept the 3 last ones of the last phase. What do you think? Thank you. regards. Serge.
Great work. I was wondering what temperature on your soldering iron do you usually use in these kinds of situations?
what kind of capacitors and resistors are them on the Xbox One because I have an Xbox One does the same thing and want to fix it myself can you give me the information so I can buy them be greatly appreciated
my xbox keeps trying to start on but turns off again and again and the power supply keeps going white to orange white to orange and keeps doing that non stop, fan tries to spin but dosn't just kinda slightly moves and stops and the power button light on the console turns on automatically right after plugging in the console,the light also stays dim, flickers and turns on and off on its own..
what what should i check?
(btw i got water on the board but i cleaned and dryed it but the problem is still there)
So how could the MOSFET have blown that capacitor up or whichever component got blown.
Hi Andy, loved the video. I have an xbox that wont turn on anymore. I plugged another power brick to it and the light stays orange. there is no sound or light when touching the (X) button. I pulled my xbox apart since it's out of warranty and looked at the board. there are no visible signs of anything blown like in your video. I will be using your voltage diagram to check everything. Two questions: Is there a power LED on the board somewhere that lights up showing that i'm getting power? And in order to test the board (out of the case) do i need to have all parts connected before it will work? (I.E. -- fan/disk drive/Hard Drive/WiFi board, etc...) thanks.
any ideas if it doesnt start up at all, tried 2 different power supplies, its not the outside power switch, and it happened after i removed the blu ray drive because a disc was stuck inside it, also sprayed it with canned duster.
Hey Andrew, this video was really helpful in helping me troubleshoot, even though I found out the issue was completely unrelated. I'm wondering if you can give me some advice:
My XBONE has the prepetual orange light no matter the power supply, so I took it apart to troubleshoot. I plugged it in without the whole thing put back together, and it fired right up. As soon as I plugged the WiFi card in, the Xbox died. I can run the Xbox without the WiFi card, but then I don't have wireless controller capability.
I'm not saavy with electronics, and am wondering how I can test if this is an issue with the WiFi card, or an issue with the circuit board. Any input before I buy a WiFi card that may not work?
My sons Xbox flash on off issue please how much would you charge to be able to repair please he is driving me insane.
I'm about to replace some mosfets on a broken xbox one s that I found on Facebook marketplace for very cheap and try smd work for the first time I'm not getting my hopes up with positive results but more of a lesson for myself , what's a good heat gun temperature to work with??
How do you know what little component is ( capacitor, transistor...) and how do you know if it's gone bad? Measuring resistance? What resistance should they be?
I bought a new power brick and I plug it in and its white and turn it on it beeps like it's going to turn on but after 3 seconds it beeps again then it turns off,what can be my problem and the light turns orange. What can be the problem?
My Gtx 980M is shutting my laptop down instantly when it's usage goes over 90% for an extended period because that's when it's voltage fluctuates. Somebody said the MOSFETS are failing because the temps are fine and the GPU is not scorched anywhere. I don't have the tools to test of fix it yet but I'm wondering how much this might cost in labor.
Hi tested my board and need a capacitor how do i find out what it is and where to get it thanks
Dear Andrew, What temperature settings did you use for air gun and soldering iron? Many thanks
hey man!! very late comment, my xbox has the orange light, i plug the xbox in and it goes white beeps and then turns off and goes orange. any ideas. please ? thank you
I am amazed How Easy you removed the chip. I applied more than 480°c with flux and the damn thing cant be removed... Can u suggest any tip? Id appreciate. Thanks
got exactly the same, but unfortunately when all components was replaced, the only changes I can see that orange light stays on, when you press on button it changes to white for less then sec and goes back to orange, before was when plugged power cable no light on power brick at all.
any suggestions?
I love your video Andrew straight to the point good work but have a question all my capacitor reading 001 can another capacitor cause that problem please anything would help 😞😢😭😭
Great stuff Andy. I'm starting on repairs on Xbox One and PS4 at my job but the soldering room appears somewhat ill-equipped. Inadequate ventilation with no clean air source and no extraction of air cleaned of flux fumes to the outside, just some crappy false-ceiling vents that seemingly just throw air up into the void above. Then there's poor lighting, no microscope and the SMD reflow tool of apparent choice being an Evolution HD200 hot air gun, which was a WTF! moment when I saw it. The HD200, as far as I'm able to tell, is purely for plumbers and decorators for strip cleaning stuff, not SMD work :o
Need to educate my employer on decent equipment to get in for the type of SMD work you show here. What bench magnifier do you recommend? We'll need good workspace clearance from lens to the item under work. I was thinking of an Amscope SE400?
What pin pitch levels are we talking about for the components you deal with in this video. What is the pin pitch for the HDMI sockets too? We have many jobs coming in with HDMI port damage.
Holy s***! Your employer definitely needs some education on equipment!! You can't do any type of this work with any reliability using anything like that. First thing is to get that ventilation sorted - if it's a poorly ventilated space that makes quality extraction equipment even more necessary. I can only presume you're US based mate because of that was over here or in mainland Europe he'd be in serious breaches of H&S law. You only get one pair of lungs after all!
The Amscope SE-400 would make a fine choice for a bench scope. It offers a good degree of magnification and a good 9" of working height. I also use an Amscope (SM4-TPZ-FRL) - mine came with a 3MP camera but I'm upgrading this to a full 1080p HDMI camera - just waiting for it to get in as I've had to order it from overseas.
UK based. Amazingly. Just done an employee survey and I spent most of my time in the 'Strongly Disagree' column when answering questions surrounding quality of training, safety and other opinions of the workplace.
Had a meeting recently where I said the attention to health & safety is half-hearted at best, despite freely available documents available on the UK HSE website. Had to inform them that they should look up safety in the Welding section of the website because soldering is considered an 'allied process' in that category.
We're a brown goods service centre repairing TVs, audio laptop and consoles. I was amazed that the company training material covers manual handling via an online test, as well as one-to-one role-play tests on how to pick up a box, yet they do not apply the same attention to safety in the soldering room where we have an IR reflow machine and other hot devices. There's been no COSHH risk assessments for the soldering room or the dust-cleaning area where we deal with laptop and console dust blockages. I've let them know I'm not happy doing any more work in these areas until we get some rational thought put into safety and get the workshop properly equipped :)
Andrew Paul I have an Xbox that trips surge protection in the PSU soon as it's plugged in have you encountered this fault and do you have any suggestions for a fix
Hi Andrew how's it going mate . V nice video I'm having something similar I have an Xbox one which works for 5 mins then it just shuts off . I have reflowed the APU but no change . Do u think the southbridge could be bad . All voltages test good when it's powered on and on stby.
Might be worth a reflow on the Southbridge bud.
I have a xbox one that won't power on at all im trying to diagnose and your videos are very helpful. I have a capacitor c9e6 above the first mosfet and resistor that's reading 210 ohms. All the others in the same position are reading 11 ohms. Could this be the reason for the no power issue? Thank you
I know this is an older video but all my capacitors are reading at aprox 9.5 apart from one reading at 71 probably obvious but would that mean that all the capacitors are bad or the one that isn't close in readings from the others ?
Hi do you think you can fix the motherboard of my xbox one i took it to a repair store and they said the motherboard has died out
finally someone that knows what there on bout thanks m8 cant believe theres not more about this
Hi Andrew how are you
Your Xbox one standby voltages diagrams link is expired or not showing image please send me a new link
Im subbed I’ll give this a shot if it doesn’t work for me Im not buying a new Xbox I’m going back to PlayStation fool me once but not twice Microsoft thanks for making this video I now have to watch tons of videos on how to work on circuit boards I’m a noob to this level of repair and won’t try until I am sure that I’m doing things the correct way
I get .65v one way but the other way I get nothing on all mosfets what is this all about?
I have one in same condition as in the video where can I get the mosfet chip at
Have you come across any xbox one x systems with a faulty u31 or u32 (location number on the pcb) chip?
Could you repost the diagram link to this if its still available. It would be much appreciated.
@andrew Paul I have found that the caps that are buy the power input will make these look bad and cause no power or turn on then off issues as well
Good to know mate thank you :-)
No problem i do have another that gets nothing at all but the link you posted to the XBOX One Standby Voltages is different from my board do you have the schematics for it? Here is a photo but you can see mine on the right is different ibb.co/f9FU5x

Ótimo vídeo amigo parabéns pelo trabalho! Aqui no Brasil também têm um cara muito bom!
Manda mais vídeos de reparos em xbox one por favor! Valew!!
+Andrew Paul Hey do you have a schematic for these boards? how do you know what the measurements should be? Do you measure a known good board first to compare?
Great vids mate!
Hi mate, no schematics sadly though would make things a heck of a lot easier! Just comparing values from known good boards. :-)
Hey thanks for the prompt response bro! Yeah I was hoping you where going to give me a different answer :P.... OK keep up the great work!
One last question non related. I had one customers Xbox one and its controller wouldnt connect sometimes wasn't battery or controller it was board related. I am a bit confused as I have read they use a combo of wifi and rf for the controller's.... what board should I replace the rf or wifi? Is there a common fault for this?
I have no power at all going through an Xbox one S motherboard. I believe it's the south bridge. Ever change any of those?
any recommendations on an xbox one that wont turn on? i have replaced the front panel and the board behind it and it still wont power on...?
Your a electrictronics wizard. Thank you for these great videos
Hi Andrew great video can you help I have xbox one with no power I have tested the power rail and I get a high reading from the first big fat on the left H8318 D423P Q1lO but I don't have a working border to see if it should be the same as the other 4. Pls can you tell me if they all 5 should read the same. Ant
Hello Paul...would have any idea on the board to start looking for an xbox one that wont power? light stays amber the whole time...no evidence of blown anything on the board..thx.
My console will power on and, exactly five seconds later, power off. The brick light is orange until the power button is pushed (turns white after the button is pressed). After five seconds, it beeps and powers off. Once it powers off, the brick light flashes between white and orange for a few seconds and then ultimately goes back to orange. What could this be? I inspected the mother board for any visible damage but couldn't find anything. Any suggestions?
Joey Scott did u fix the issue my Xbox has same Problem it might be dried upp thermal paste
Ray Rua Unfortunately, no. I took it to two different shops and no one was willing to work on it. I ended up purchasing a used console from Gamestop.
Hi , I am facing the same problem in my XBOX one , Bought it from US last eyar and everythingw as running good but suddenly its starting off after few seconds, I checked microsoft and other sites to resolve thos issue and tried all of them but still cant resolve :( Can anybody help me to advise that whats the problem as i showed to one local repair shop and he was saying that he will check motherboard and can resolve or permenantly dead so im confused that what to do, Any leads , In my console i havent found any physical damages or marks on board or anywhere.
Thanks
Diagram Picture ist down :(
My brothers xbox one will not start. The front light does not even come on. It will make the ding noise though. There is no signal to the tv. The power brick light stays a solid orange. I tried my own working power brick on his xbox and it does the same.
hey Andy I have no idea how to do any of this kind of stuff and I have it any professional advice for what i should do
exelente su trabajo, lo sigo mucho desde colombia ¡¡¡gracias!!!
i have had to do this exact repair exact same mosfet and all
Were you buy the parts?
Hi great video!!! I have exact issue here, I’m looking for a list to the components needed to replace? Would be a really good help thanks for reading and keep up the good work!
Question. Idk if you're ever gonna see this, but the other night I was downloading games on my Xbox and it froze. I shut it off and now when I try to turn it on it beeps and lights up, the fan comes on but no signal and it won't connect the controller, also to turn it off I have to hold the Xbox button down
It will also accept a disc and eject it but that's about it. I've tried every possible trouble shooting step
Sounds like the hard disk is dead. You'll need to replace it with a new one - it'll accept either a 500GB, 1TB or 2TB HDD or SSD.
@@AndrewPaul oh that's not so bad. I was thinking the APU was fried
Yeah it's an easy fix this one 👍
Hi there,
we got some problems with Xbox One, i hope so u can help us.
Problem is that Xbox One cant recognize any xbox one controler, so we first at all try to change wifi card on xbox and that didint work...can u help us with this problem? Any suggest will be helpful. Tnx all!
Ever done an XBOX ONE S? I have one that goes up in tone (turn on noise) then down in tone (shut down noise) right away.
After plugging in, the fan spins a quarter turn several times and then does nothing.
Voltage at 12V input to the board is 11.94V. Seems okay.
Any ideas?
No charred mosfets that I can see.
No visible damage at all, actually.
I tried "reballing" by heating with a hot air rework station for a minute or two. Not sure if I got the solder to flow but it had no effect. Hmm...
I also can't hold bind/eject and press power. It doesn't ever even try to read USB.
Well the hard drive still works! I can see all of the partitions on my Windows 10 machine.
My PSU light is orange until I plug it into the Xbox, at which point the light just goes out. Should I still look into the mosfet?
@@MsPoliteRants Yes
@@AndrewPaul ty
Where can I buy these components??
I used a Boxmod and the Mosfet burned up would you be able to replace it ?
Hello there. I just wanted to mention I clicked on the link and the diagram is no longer available on tinypic.
I have the issue of when I plug the power supply in it flashes then solid orange then will not turn on! Is the South bridge you think?
Could be but check standby voltages first - there should be a link to the diagram in the description.
My friends xbox one took a fall won't turn on no it's not the s anyway when I plug a known good power supply into it and nothing stripped it down out of warranty hence why I got into it and I can't find any props on the board a lil nervous about taking heatsinc and clamp off too look don't want to do that if it's not the issue please help lol
Remember when you have the console set to instant on under power settings. When you power the console down the light on the power supply will stay white. When you set the console to power save under power settings. When you power the console down the light on the power supply will turn orange after its finished powering down. In my opinion I prefer an external power supply. It helps you know what the console is doing. Plus its much easier to replace if it goes bad.
What about no bad mosfet and reflowed gpu and cpu but still no power. Both power bricks work and my other Xbox powers up fine
hello good video , there is no more this link XBOX One Standby Voltages Diagram
Ok no problem - I'll look to get it uploaded to a more permanent location ASAP.
@@AndrewPaul thanks , i have this same board but the diference is that the xbox is just die dont show any ligth when you trie to turn on and the power brick is permanent whit orange ligth can you give me a clue of how to proced ? i already check that the 12v is not there and the coils have 10 ohm i dont know is this is normal
I have an Xbox one s which when powered on
the power sound beeps and the white lights comes on for about 5 seconds and then the power goes off again.
Is there any help?
Power box probably
SO isn't the Power Brick?
Good days Andrew, I have here two motherboards of Xbox one that have a strange failure, when I plug them they ignite and extinguish three times, stop working and do not ignite. I think that the failure comes from the mosfet Q5F2, since it gives me short circuit. A greeting.
Could well be the problem there then my friend. Remove it and see if the short is removed. If so, replace the Mosfet and hopefully it'll be back up and running :)
Thank you very much, I have changed it into other one of another motherboard and now it ignites, but the led goes out to 2 seconds and the fan does not start.
Is it a symptom of which it is necessary to do reballing the APU?
I have an ACHII IR Scottle 6000 to do reballing.
A greeting.
my xb1 will not turn on no beep nothing, iv tryed 3 per bricks and no luck just an orange lght,
but all 3 bricks work fine on the consoles, do u think what's in this video is my problem?
Maybe not this particular component but good chance something may be toasted.
Eric Marechaux Same with mine,I took it apart last night to check my Disk Drive cause it's not reading disk for the past couple months I even tested it to make SURE it powered on and it did so I assembled everything back and when to turn it on this morning and nothing not even a sound.The power brick just stays orange I don't think I short circuited anything to my knowledge.
+OxMr937xo check the ribbon from the front panel - it's tricky and probably not seated correctly.
hello, good video, what about if the 3 pins on top and the four on top of the mosfet is beeping with the tester and beeping in ground also ?
Very good Andy
