MacBook don't turn on

MacBook display has no picture after turn it on.

I don't hear any fan or hard disk activity sounds.

the sleep light doesn't turn on.

The computer doesn't seem to have any power when you try to turn it on.

Battery is full; and I tried to switch and/or remove both of ram sticks; no effect.

I tried the SMC reset too.

About the power : the light on the original power cord doesn't turn on green or yellow when plugged on magsafe; but if I use the cord from my new PBpro, it turns on green.

That's it.

Any help ?
