Blank Screen

[iown_azz]

Every time I start up SC2 by screen goes blank like it is sleeping but you ca still hear stuff. Why is that and how do I fix that. MY screen is a LG 47" Flat screen TV

My guess is it has something to do with the fact that you're running a 47" setup, that's pretty redic.

Try lowering the refresh rate of your monitor outside the game. Also, try a different screen resolution.
