It slid off my bed and everything else was perfectly fine, but when I tried watching something, i realized the volume icon was grayed out and the buttons display a locked sign. No sound through my earphones or speakers. I'm thinking that when it dropped my earphones must've jammed something because there's a red light coming out of the jack. Are there any troubleshooting techniques or am i going to need to get it repaired? I'm a little worried about going to the apple store because someone told me a diagnostic costs about 100 dollars and then on top of that the repair costs. I don't think the warranty will cover this, but i'm really hoping something like this will cost under 50 bucks.
