MacBook late 2009 Not powering on

Text:

So I have this MacBook (late 2009) which doesn't power on. I got it this way so I've never seen it running. When I press the power button the cd drive spins up as there is a disc in there, the sleep light comes on and the fan comes on. That's it, no other activity even after repeated attempts to reset the smc and pram. Plugging in the charger charges the battery but turns it on instantly when it's connected. If I turn it off, 30 seconds later it will power on again. I tested the ram sockets individually with both sticks, no difference. No beeps with no ram either. I also removed the keyboard to rule out the top case and powered on by shorting the ribbon cable connector, same thing. I tried removing various connectors to see if a drive or airport card was the issue, they were not. I even tried taking the battery out and letting it "rest" for a few hours, nothing. Also does the same off the adapter only. The guy I got it from recons the lvds socket is faulty and that is causing it but I can't see that stopping booting? Right now I'm thinkIng new logic board but I'd rather try anything I've missed before I do that. If anyone has a suggestion I'd be glad to hear it! I'm not afraid of a soldering iron either, I have a reflow station too.
