Hi New here and looking for help. My two sons are home for Christmas. As every year they love to play some Burnout on Xbox. The first day it worked as usual, but yesterday it was completely dead. The power cord is working. Tested with multimeter. I’ve taken it apart trying to trace with multimeter. Not really sure what I’m doing. I attach some images. There is a wire soldered inside. Is it a mod? What might be the reason and can I fix it right away? Any guide out there? Jimmy

I have a 1.6 revision board which shut down in the middle of using it. I have tested the PSU which is working correctly (have tried in another system also). I have traced the problem to this MOSFET - Q2F1 not outputting 5V.Can anyone guide me on a replacement? The numbers on it don't give me a good guide on an equivalent/compatible one.

I've been through hell with this Xbox over the past couple of weeks so let me give a bit of a rundown. I've got a 1.6 Xbox that I installed OpenXenium on using an LPC rebuild board, Chimeric's IDE cable, StarTech IDE/SATA adapter, and a WD 2TB drive. For the longest time I had issues with the OpenXenium install where it would FRAG if the chip was installed. I checked continuity and everything was fine with each VIA to its corresponding point, so I redid my soldering twice and it booted into OpenXenium. I then install a dash, setup the new drive, and put the Xbox back together. However it FRAG'ed again whenever I put the top case back with all the bottom screws. Took the case off, still FRAGing. I realized it was FRAGing with just Chimeric's IDE cable after a couple hours so I got a replacement cable, and everything worked fine with the top case back on. Until it didn't. After turning the Xbox off for a few hours it wouldn't turn back on, period. I took the top case off, and it powered on fine, but after a couple seconds I heard a loud whine/squealing noise from the right side of the Xbox (which I assume was the PSU) > turned the Xbox off > and then it never turned back on again, even with just the bare board. So I replaced the PSU. Issue fixed, it powered back on fine. But when I put the top case back on, it wouldn't power back on, and now I'm at the same spot I was before. The Xbox is not powering on no matter what I do. So here's what I've done so far since then to try and narrow this down: I do not know for 100% certain that the motherboard has been case swapped, but I have no reason to believe it was. The bottom stickers were all intact and the screws were not exposed, and there are no missing/extra screw posts on the bottom of the case compared to the board. I've also tested power with the board and PSU isolated from the case and I'm still not getting power, so the case is not the issue I've checked continuity with all VIAs to their corresponding points with a multimeter and they all have continuity. LFRAME is also not grounded I've checked the PSU using this chart here . I'm getting 5.3v on every orange, 0v on white, 0v on red, 0v on yellow, and 0.3v on blue I'm getting 3.25v-3.26v on the collector chip Anyone have any ideas on where to go from here?

I got an xbox v1.0 motherboard with an xecuter 2.3 pro modchip that was not working. I took it apart and found the d0 wire was loose, so I resoldered that connection and hooked everything up and the system ran fine for about 4 hours, at which point I powered everything down and went to bed. this morning I go to power on the unit and the blue lights on the modchip light up and the fans spin for a second, but no lights on the front panel and nothing else happens. the capacitors on the power supply and near the psu connector on the motherboard all look fine. not sure what else to check, so any help would be appreciated. Also, the clock cap was removed before I got the xbox, presumably when the modchip was originally installed VID_20220223_031845379.3gp

So I had the issue where the xbox would come on as soon as it was plugged in and the power button would not work to shut it off. So I did the trace repair on all 5 traces in the tutorial. Now the xbox will still come on as soon as it's plugged in but it will not shut off Randomly. Is there another trace other than the 5 in the tutorial That need repair?
