I've just acquired a used iPod Touch. (Part of a job lot that I bought). It seems to work okay, except I can't make the backlight come on. I presume that there's some setting that switches it on and off but I can't find it. I have done it on other models, but I can't see any backlight timer on the menus. I know it isn't broken. It did light up for about a second, then went dark again. If it makes any difference, it's a second generation, specifically model no A1288.
