How do you mean, use Hyperterminal? Do you mean that the player's running, and you have to give it the serial command to get it to start playing music? If you do this, does the screen come on properly?

I assume that there is no sound output until you do this? In fact, does the sound come out once you've done this?

All of this suggests to me that maybe the display panel is not working -- i.e. the buttons aren't responding. Can we try to chase this possibility down a little more?
