Nintendo ds lite repair

I had the same problem, the light would come on and for a split second you'd see a blue screen on the bottom and then it poweres down again. its because the thin ribbion cable is not plugged in all the way. On the white connector where the ribbon plugs in , there is a little black door that clamps down on the cable keeping it inplace. make sure youve clamped it down or it will fall out. I thought i had it plugged in well there too ,but when i powered it up i had your problem so i opened it up and found that the ribbon wasnt in all the way, and then it would power up, but my touch screen was unreponsive. i think i chiped something on the mother board. hope that helps

Call the company and tell them TRY IT
