cheers i think thats the best idea i just didnt have any to hand when it popped out before i think it might be the motherboard on the ds now.
When the power supply gets plugged in the red indicator turns on for a short period of time but it always seems to be the same amount of time apart from one time i got it too turn on but hte system had to be reset and once the setting are done you have to turn it off and its never turned back on after for more that a half second

just a green light flashes on and turns off again with the red indicator.
