Dropped my laptop. Help with backlight bleeding and potential hardware issues!

Yesterday I dropped my month old Inspiron laptop from approx. 1 meter height to a concrete surface while it was turned on. So far, miraculously, no major problems are showing except that the screen has some yellow tinting on the upper right corner. I searched about it and apparently it now suffers from backlight bleeding due to the damage I'd caused. Can this be repaired or does the screen needs to be replaced? No cracks nor scratches, just the yellow tint.

Also, what about the hard drive? I don't hear any scratching or clicking sound as described in forums I visited. I've just noticed that the Dell logo takes a little longer to pop when I turn the laptop on but overall the laptop works fine. Applications respond fast like the usual. 

Any advice on these?
