I have a 1 GB Sansa Clip that has a dead screen that’s not coming back. Before I dispose of this unit, I’d like to try to use it “blind” for a little while. It is currently in radio mode. What sequence of button pushes do I need to do to put it in play music mode, random? (If people could do it with their working models and jot down the button sequence, I will be able to put it into that mode). Thanks!
