XBOX 1.2 TSOP flashed with Cerbios that will power up and run for about 2 minutes and then just powers itself off
Hit power button again and it powers on right away.
This time it stays on for less time...and each iteration of this powers it on for less time than previously until its only on for 15 seconds or so
After I let it sit for a half day, it'll run again for a couple minutes and then exhibit the same behavior.
This occurs regardless if the DVD is connected during power on sequence (have DVD check bypassed in Cerbios). This sounds like a classic Cap issue...or could it be a power supply issue? To rule out one or the other, what is the easiest way to determine what is giving/causing the power off signal?
Thanks!
