'Media File Selector' blank screen
I am not sure whether to making 'jQuery' version down to some level is good or not. But, I tried to downgrade the jquery version to 1.5 and it works well with my website.

I refereed this post:
Media 7.x-1 Library tab empty

Now, I can see all my images by selecting 'jQuery' version - 1.5.

To do so:
Go to 
Home » Administration » Configuration » Development



Thanks!
