Laptop won't boot. LCD screen & Apple logo on top cover won't light up

I am the only owner of this laptop and have had no problems until now. I replaced the battery over a year ago with a crappy refurb from the Internet. It never held a charge, so I replaced it in November of 2012 with one from the Apple store. No problems with battery. Over the last three months, I had sporadic issues of booting to black screen, but it always worked on second try. Today, I booted the computer and this time it is permanently blank. I tried reset fixes from the manual, hooking up a separate monitor and the OSX install disc. The machine will not release the disc, the VGA hookup showed no signal, the resets did not work. The battery is at full strength, I only use the 85W adapter that came with the machine.

Does anyone have any ideas?
