Resolved Question: I've broken a second Sansa Fuze! Please, dear god, help me!?

I had a Sansa fuze 4g for easter from my nan and I LOVED IT! It was such a cool, easy to use, funky little MP3. Then the screen went a very washed out blue colour and it stopped working, this was only a month after I got it, so my parents went through sending it back, finally, after six months, i got a new one, that was about two weeks ago. Tonight I went out on the trampoline in our garden and was listening to my music. Then the song stopped I took it out of my pocket and the screen was a dark blue, it still is. That was over an hour ago, i can't turn it off or connect it to my computer. I need to fix it quick or my mother is going to be-head me when she finds out it's broken.
Please help me! Can I fix it myself or do I lose my head?
It's not smashed up but it just won't work, it doesn't look like theres anything wrong with the stupid thing!
