if you pressed the power button while doing this you might want to disconnect the battery cable from mainboard for a couple of minutes and then after you've screwed everything back together - power on.
That could be the problem. I'd suggest following wout.martens advice.
Open it up again and disconnect the battery for a few minutes. Press the power button a few times after disconnecting the battery. Leave it like that for a few minutes and then connect it again and reassemble making sure the screen connectors are connected back properly.
You don't need to remove the battery cover to disconnect the battery as the connector is accessible.
