I picked up a used original Xbox one (1540) and it's not powering on properly. It comes on with the normal sound and light, but after 3 seconds, it shuts down. The power supply appears to be working properly, so I opened up the console and cleaned it thoroughly. That made no difference. While it was apart, I noticed that the cooling fan slightly "bumped" when power first came on but it doesn't actually spin at all. I tried turning it on while manually spinning the fan with compressed air, in case there is an rpm sensor that wasn't being satisfied to keep it powered up, but no joy.
I checked for power at the mainboard plug that supplies the fan and I got 12vdc during the short time that the power was actually on. Next, I pulled the fan out, put it on my bench and separated the fan assembly and circuit board from the fan surround and bearings. I have continuity from the mainboard plug to the fan circuit card on all 4 wires, so I inspected the circuit card for any obvious damage and when I didn't find any, I reflowed all the components that were diode size or bigger just in case. I didn't want to reflow anything smaller in case I ended up knocking off some of the really small components on there.
My next "guess" is to buy a replacement fan and see if that fixes it, but I wanted to get some more info first, seeing as this is my first experience at all with this system.
-Is the fan supposed to start spinning immediately?
-Has anyone else had this problem, specifically 3 seconds on and then shutdown, and if so, did replacing the fan fix the problem? There are a number of forums that address no power at all or power shutting down after a few minutes or later, but very little even mentioning the few seconds on scenario.
-Has anyone fixed this particular problem any other way?
Thanks for the help.
