I BOUGHT a USED GAMECUBE on ebay.IT APPEARS TO BE DOA. i hooked it up right- no lite, no motor sounds. HELP!?

i carefully hooked up the system- power brick cord into a new surge suppressor strip(which works cause i tested all 6 outlets with a lamp). AV cord went into analog slot and into my newish panasonic tv, which has the quick hookup on the front. The plugs are color coded , and i seated them snugly. I tested the quick hookup(video 3) with an atari flashback console, and asteroids played as good as always.plugged in the nintendo controller to the #1 hole and pushed power. NOTHING. No light came on, i heard no sounds of whirring motor. I think i have done everything right and was sold a dead cube. Im also sure that mr dad who sold me his sons cube will tell me its used and "as is" even though he said it was "working fine". There was no mention of "as is" on the auction. If YOUR mom came to you with this story, what would you tell her? I think I am going to get screwed hard(over a $100) here.GAMERS & EBAYERS, PLEASE HELP ME!!
