inoperational backlight

  1. New GL-121, but no backlight - help, please

    Casio G-Shock
    I got a nearly new yellow GL-121 G-Lide off the bay, but when it arrived the backlight was not operational. I just now put a fresh battery in it, but it didn't help. This is strange, because the light button also functions to start/stop the stopwatch and CDT functions, and those work so I know...
