Hey guys, Ive got a problem..
Got a 1.6 xbox here, hdd/dvd-drive disconnected, connecting power supply and it turns on by itself then off again..
then I try hitting the power button but nothing..
then I try waiting 5 minutes with PSU connected and hitting the power button=> it boots, for about 2 seconds, then turns itself off and powerup doesnt work again..
fresh chip, fresh PSU.. and it just wont boot.. Ive also tried to remove and install a new MMBT3906LT1 transistor incase the mobo has been put in a 1.0 casing and blown the transistor, but still, nothing..
Some interesting things happens if I hold the power button in though, after about 5 seconds, and continues clicking sound from the PSU (hard drive and dvd-drive NOT connected so Iknow its the PSU that makes the sounds) it boots up but shuts of again.. no fraging, just problem with power somewhere..
also, If I just let the PSU be connected for about 5 minutes, and try and turn it on, it turns on, and shows Xbox logo, but then just turns off within 3 seconds, and wont be turned on again.. anyone know what the problem could be?
It could ofcourse just be another transistor on the motherboard, and it could also be a really easy fix, thats what annoys me about this problem.. I dont wanna throw the xbox away either, especially when the solution could be so simple.. anyone?
