Hey all, I'm having a small problem. At the small business i help run we have 2 cash registers, both are electronic and have lcd screens. All of a sudden one stopped working, the background lights up for a split second and then turns off, the moniter is on but not hte backlight. I messed with the settings and nothing happened. I made the settings identical to the other one that is sitll working and it still doesn't work. Any ideas?
