When I turn on my DS Lite, the green light powers on, but nothing happens. There is no sound at all, and the screens don't show up. I disassembled it and tried to eject the screens, to see if the DS Lite recognises that one or two screens are ejected. As many of you know, if a screen in the DS Lite is ejected, when the DS is powered on the green light blinks and suddenly the unit shuts off. This won't happen, the green light remains still powered, and nothing changes. I tried to eject Wi-Fi and Mic, as I said before, no change. Only the green light. Possible motherboard problem? Do you have any technical suggestions, considered that I don't want to buy a new motherboard? Do I have to check some resistors for example? Any help would really be appreciated. Thanks.
