Hey man, you just helped me solve a problem that's been nagging me for years. I was able to revive an abandoned Xbox thanks to this video, and now have several more lined up. Thank you for your great content!
Hey i got 0,62V on the both left mosfets if i put the black on the end of the mosfet and red on gnd the 3. mosfet gets 0,064V so i think its a bad one. BUT if i switch the red with the black side i should get 1,9V but i get 0V i dont understand... is this related to the defective mosfet or are they all defective? Do I need a other mode on my multimeter? I used diode mode
i dont know if u can help i have xbox one x with disc drive not loading disc iv checked the voltage on the connection is (nc 3.2v 3.2v 5v 11.60v 11.60v) but the last 2 should be 12v but on the motherboard im only getting 11.60v and i cant see why and i know the disc drive works as i tested it in another xbox one x
Sadly I'm struggling to get retimers as Digikey has a supply problem at the minute but as soon as they come back in stock I'll let everyone know. The mosfets I buy from Digikey @ www.digikey.co.uk/en/products/detail/toshiba-semiconductor-and-storage/TPN8R903NLLQ/4332064
ive tried 3 different motherboards in diode mode for mosfets they all read 6.2 roughly but when i check with leads the other way round every one of the three boards says OL am i doing something wrong thanks i have all the equipment you use as your who got me started on this including the infurider multimeter please help
It only happened the other day 1st time never had issues dnt go on it much and i shut it down power bye hand cos control was dead so after that it just turns on lights up nowt cums on screen no hdmi found on screen so it's definitely summet stupid I've dune wrong wen manually shut it down then had this issue Wen put on other day I've got my PS4 pro I've not checked hdd dnt no how to do all format stuff I've got Brand-new laptop cud take ther 1tb HDD out that try it in Xbox one s havnt got clue Wat to do all my game's files on HDD just want my xbox working again pay if can get it sorted cheers been watching ur videos ur epic mate at fixing stuff genious
I'm going crazy with my Xbox one S because the 12v rail has no short (checked the thermal cam anyway, but nothing stood out), I checked the continuity on the gate of each MOSFET to the resistor next to them them in the circuit (flipped leads around just to see; got .750k in one direction, OL in the other on all 3 phases). Again I compared the OL to other 2 boards and they were doing the same thing, while other youtubers were getting 1.9ish. Weird. All of the capacitors and resistors on each phase test normal. Well, maybe normal. the 2P20 resistors on each phase (the 3 closest to the edge of the board) are giving me a short, but I compared my measurements to a couple of other boards and they were doing to same thing, so I'm guessing these only put out 2.2k with power, but that seems like odd behavior for a resistor. I don't see any other option except a solder reflow and cross my fingers, cuz I don't have time to sit around all day reballing APUs with my naked eye XD. Oh, i forgot to mention the first thing I did which was try a different PSU. Same behavior. I did notice something possibly worth noting though. If i hold the bind button like I'm trying to get into safe mode, it will come on like normal and beep and turn off obviously, but if i continue to hold it, it will try again to turn on, but no more.
I've got same problem with mine goes on for so long but nowt I've took HDD out but still does same cold air blown out I've not been on it much any advice aww cud u sort it il pay u cheers
Thanks for the video! If all three mosfets are doing great, my power supply is putting out 12v, what else should I be testing? I could really use some help. Thanks mate!
My Xbox One S powers on with the FAN plugged in, no drives. After I connect the CD and HDD, it will power off 2 to 3 seconds after I switch it on. I managed to boot once and set the power mode to quick start so that it doesn't go off completely. That kept it working fine until one day i had to unplug the power. Since then i haven't been able to get it to power on without going off a few seconds later again. What could be the problem?
That would be quite difficult to say without seeing it in person as it could be a number of things. You may have a bad part such as the disc drive or it could be a main board issue such as a bad power delivery mosfet. Unfortunately it would be impossoble to know for sure though
@@TheCod3r thanks for your reply. Your videos have been very enlightening and I really appreciate your sharing. The problem seems to be intermittent, though its not working most of the time. After dismantling down to the board again the day before, the box was able to startup normally. Keeping it in quick start power mode allows me to switch it back on with the wireless controller. I'll try and save this battle for a later time when I need to unplug the power cord again. Could you please share the link to the video on the one x with the CD drive and power MOSFET problem you mentioned to Tony Mondragon that you were editing? Thanks so much for your Channel!
@@TheCod3r I'm just getting into console fixes and stuff already done a couple of switches and got a xbox on s hdmi port to do. And couple of controller drifts to sort out.
@@TheCod3r yes mate learning alot. Main thing is learning how to read the motherboards and diagnosing shorts and stuff. Then soldering the tiny little components I cann just about see 🤣 need to invest in a microscope like urs when I can afford one.
@@liamowen7447 you'll definitely get there, just build your equipment up slowly. My particular scope costs around £400 without attachments so it's quite expensive. If you don't want to invest that kind of money straight away have a look on the Google play store for an app called Cozy magnifier. It's a great app for android and if you get yourself a phone desk mount and a phone hdmi converter for around £30 total you can have yourself a pretty decent microscope on the cheap
I've got a short to ground as well on the power supply but when I test the MOSFETS they all read fine. Where would you suggest I check next for the short? Thanks for the tips btw!
Hey bud, the mosfets do rarely test ok even when they're not. I'm actually editing a video right now where the mosfet read normal but still had a problem except that one was related to the disc drive circuit on an xbox one x. I would say if you have no visible damage to any components the next best thing would be to just start removing components one by one. I would start with the mosfets and then move on to the mosfet driver ICs. You can always put them back if they don't clear the short. Be sure to also try the capacitors as they can essentially turn into a wire and short to ground

Thank you for the great feedback mate, glad I could help ;) good luck with the rest of them 😁
Please Help
Hey Can You Give Links On Where To Purchase The Mosfets ?
The part number is TPN8R903NL and you can buy them from Aliexpress, DigiKey, Mouser, RS-Components etc
ما شاء الله

Good video. :)

What sort of microscope camera setup have you got? Seen a few of your vids, but this is the first one under the scope. Keep up the good work 👍
i have the same problem but not good at soldering is there a place where i can send it to you or anyone who you know
Thanks for the video! If all three mosfets are doing great, my power supply is putting out 12v, what else should I be testing? I could really use some help. Thanks mate!
there should be 6 u should be testing, also plug it in and check the test pads for shorts or resistance where there should be voltage
Hi mate where do you get them fets ? Thanks
Usually digikey mate, the part number is TPN8R903NL :)
Let.me.ask u what about the ones that power on and then powers off u fix those
It really depends, I always take a look but a lot of power on power off consoles tend to have cpu shorts, but some turn out to be fixable
