2013 MacBook Air screen flickering; manual shutdown and now it won't power up. HELP!

• 2013 MacBook Air 13.3/1.3GHz dual-core Intel Core i5 with 3MB L3 cache (Turbo Boost up to 2.6GHz)
• 4GB of onboard 1600MHz LPDDR3 SDRAM
• 128GB of flash storage
• Intel HD Graphics 5000
• Preinstalled OS X and iLife

43% battery life (not plugged in at the time), playing Bejewelled Blast? on Facebook at the time.

Screen started flickering vertically; pressed the power off button and the entire screen started to flicker.

Pressed power off button and eventually the display shutdown. Now, the **** thing won't start up.

I've tried plugging in the A/C power adapter and the light was orange and eventually turned green.

Hot to the touch so, I took it out. Other than that, can't turn the **** thing on to try anything.

HELP!!!
