Hi,

If you open the cover for the SIM-card, you will find an OFF button. Use the tip of a pen or a similar object to hold this button down for 5-10 seconds and then try to power on the phone. If the screen is still black after this, I suggest that you perform a software repair using PC Companion to see if this can help.
