Magsafe adapter doesn't light up, laptop doesn't power on.

I split a cup of coffee on my Macbook yesterday, I unplugged it, powered down and removed the battery straight away, gave it a quick wipedown and let it sit screen open keyboard down.

leaving it for a couple of hours, I removed the topcase with the guide on here to ensure that liquid didn't get through to the logic board, all looked ok, I reassembled it and let it sit over night.

I power it up this morning and the power button and trackpad work but all the other keys are dead, thinking that I may not have sat connect from the topcase to the logic board correctly I take it apart again and re sit the cable, reassemble and now it wont power on at all.

• I have power in the battery
• used the mag safe adapter in other power points

but no green light on the magsafe connect and laptop won't power on.

I am thinking that I will need a new topcase and a new logic board, but I am hoping to exhaust other avenues first.
