Blank screen

my razr screen is blank. on the outside & inside.
i can turn it on, make calls, recieve calls, everything.
but i cannot see. i read that i should hold * and #,
but this does nothing. i also read that if that doesn't
work then it must be the flex cables.

if that is the problem, can this be fixed? and how?

My razr is retarded. The screen is all white and blank, but the phone itself still works but you just can't see anything. I read that if you turn it on its side and bang on it that the screen will turn back on...I did that but all it does is it tries to load the screen and it gets all these thick red lines across it, and then it goes blank again. Any help?

My screen just completely went out too. I've never heard of those problem solvers above^ so I'll give them a try :/
