Hi, you said your whenever you phone is powered on, you can only see the button back light and the screen stays black, from this explanation, you have a LCD or screen problem. LCD means liquid, crystal, display. Since it is not a flip phone, the solution is simple, it's either the flex connected to the lcd is bad which you have to change, or the LCD is bad. In some rare cases, both might be bad, which in all three case, you have to change them. But if the LCD does not have a flex as i believe in the case of the blackberry, all you need to do is to change the lcd and i hope it will not cost you much. i will sincerely advice you to take it to a mobile phone technician to replace the LCD for you
