Wierd...My psp1000 charger did something funky right before I traded it in for a psp3000...for some reason when the AC Adapter was plugged in and the psp was turned on , I got 3 verticle stripes of pixels that were red :-/  if I would take out he battery to drain the power from the botherbaord, then put it back in and  power it on with battery or use the ac adapter from my psp2000 the lines would go away.
