Htc rhyme screen black but phone powering on

[flower20]

Hi
My htc rhyme screen is black unexpectedly
phone is powering on, I have removed my sd card now into another phone
as I cant see as my screen is black and I cant put in code to also log in, how do i down load photos from phone itself

Have tried rebooting, holding top and volume switch on together, tried linking to computer with usb but computer not reading phone storage. downloaded htc sync, updated drivers
nothing works

thanks
