Hi, I know this is super old but an internal fuse has blown somehow much like the problem with PSP's, the fuse is located next to the DC jack component or between the VGA slot and DC slot, just bridge the fuse with some solder and your good to go, but I wouldn't recommend leaving the unit on standby while sleeping etc, always switch off at wall when not in use.
