Hi,
Have you seen a bright white blank screen on PPC. my PPC started showing this and neither soft reset/ hard reset works. Even if you take out the battery and then the moment you plug it in, it just shows this bright white screen and the backlight never switches off. The battery wears off after some time and if you put it on charger, it the same story.
I am sure a circuit has fried inside and I can throw it in the river, but if you know of the problem/solution, then pls help.
