About a week ago, I got a used Dw-5600E in the mail. I have changed probably a dozen G-Shock batteries in my life and never had a problem, so I guess I was finally due for one. The issue with this watch is that the EL stays on. The LCD display is working, the watch is keeping time, but the backlight won't shut off. I have shorted it multiple times, removed the module from the case and made sure the tab that activates the light hadn't been bent inwards, and all to no avail. Is there something I am missing? Thanks in advance for any help.
