Hello! I have notice something minor on my psp screen. When I look at the screen from an angle and really reallllyyyy close I can see extremely thin vertical lines. Not the type of line that the psp are displaying when the screen is damaged. It is only visible really close, from an angle and only on bright grey background. When I start PS1 games it is NOT visible AT ALL. The lines are spread across the display evenly. And I was wondering if that is normal for old LCD displays so that is why I am asking here. It looks like the Nintendo DS line bottom screen with the sensors for the touch functionality. I hope I am not going paranoid because my other PSP (it was 2004) had the "death" vertical lines.
