No power to my MacBook Pro 17inch 2009

I replaced busted left ,right and subwoofer speakers in my macbook pro 17inch 2009. The computer was working just fine before. I installed the logic board in reverse of how i put it in and now i have no power at all. No video no sound no lighted keyboard . when i connect the charger its green then turns amber. also nothing from the battery indicator. I checked all flex and connectors. I have also replaced logic boards in the past with no problems but never a 17 inch.
