Question about Computers & Internet
Try the standard start the laptop holding option and command and p and r (and hear that boot sound twice or three times; note that it gets louder)--this clears any info the laptop might be holding onto, like "I'm suspended with a blank screen". You can also unscrew the bottom plate and disconnect the battery, hit the power button to clear any residual power, reconnect the battery and screw back the plate (or maybe you just have a battery door to simplify!); then, maybe it boots, but I suspect...
...you screen is bad (since your hear the boot sound); to test: assuming your TV has an HDMI port, get a miniDP to HDMI cable (e.g. under $15 via Amazon slash dp slash B00APLKGA8); then physically connect, then change the input on your TV and hope there's a picture (e.g. your desktop background)--if you can't see anything, unplug and replug the thunderbolt/miniDP connector (or borrow any good laptop and verify you can see it on your TV)...
Assuming it's out of warranty (otherwise, you should be at the store already!), so pay $ to your nearest Apple store, or (for the brave) buy the part (hoping LCD panel; i.e. your TV saw a signal), and see repair guides via ifixit dot com (just note the super fine print on the bottom of your laptop; you'll need your Model No; A1286 or to do some searching).

There should be a "displays" icon in the top right portion of the menu bar where you can change the display mode to "Mirror Display" whenever you connect the projector.
If it's not there go to "System Preferences" > "Displays" > "Display" tab and put a checkmark next to "Show displays in menu bar".
Also you can go to "System Preferences" > "Displays" and leave it open while connecting the projector and change the settings to "Mirror Display" there.

This is one of those questions that's virtually impossible to answer, it could be anything.
Your best option is to take to a mac specialist (the dealer where you bought it) or to an Apple Store if you have one near by.
It may not need a new hard drive, it may just be corrupted and need sorting out. On the other hand it could have failed mechanically and will need to be replaced - check your warranty. There have been a number of reports of HDs failing in some models and Apple have replaced them free of charge as there was a manufacturing fault at the HD factory that didn't come to light until the drives had been running for about a year.
You have been using Time Machine to back up your work haven't you?

Get your Mac OS DVD out, restart the machine with the disk in your optical drive, and after you hear the famous mac chime, press and hold the C key while it starts. When you reach the install window, don't install but rather open the Disk Utilities App and run a verify of your hard disk, also repair permissions. Then restart as normal. This should get you back to operation.
