I've got my PSP for about a week mostly using it for emulation (Nes, Snes and Genesis). Yesterday I suddenly noticed a grey stripe at the left side of the screen. I'm not quite sure if it was there before or not. The stripe is perfectly straight from the top to the bottom of the screen. It's very clearly visible on a black background (like when running an emulator). If the backgroun has a different color (like when playing a PSP game) it becomes less clearly visible and instead of being grey it's a few color tones lighter then the background. The stripe is entirely not visible on a white background.
I'm not sure if it's really a problem with my PSP or if this sort of thing is normal. Like I said before I don't remember seeing it before yesterday, but on the other hand I might just have missed it.
Does anyone know anything about this?
