I have been messing with a DS Lite that will not power on. When the power switch is engaged the green light flashes for a second and then nothing else happens. When the unit is plugged into AC power the orange charging light flashes for a second and that's it. I have opened the unit and checked all of the wired connections and all appears to be fine. I am thinking that it may be the F2 fuse, but this seems to be a bit different then the typical behavior asociated with that fuse. Any help would be greatly appreciated.
