Yeah that doesn't sound good. What should happen is that when you press the button the mirror locks up and you can see 'live' what the sensor sees. I've been trying to think of anything that would not let that happen but I'm not getting anywhere. What type of lens? Just reaching at this point but maybe try a different lens.
Also, try pushing the button in and wiggling it to see if maybe it is just stiff.
But I'm afraid that's all I can think of. Maybe somebody else will jump in with a better idea.
