The 'fix' is incomplete. The flicker is due the wire which you rubber-banded intermittently losing contact. When this happens, the PB becomes battery-powered instead of AC powered, and you see the screen flicker. A more permanent fix requires opening the power supply, cutting out a section of the wire where it is internally broken (this happens right where the wire enters the power supply), and soldering it back together. > My AC adapter failed, depending on which way you bend the wire coming out > of it.
