King of odd, the deflector removed will still make the mac boot, but
your fans will run at 100%.

try to unplug your mac and plug it back in and if you hear a few relays
clicking and still doesn't boot, i would have your machine serviced. if
you plug it back in and you don't hear any relays clicking, your power
supply is fried or your power bar have no power "if behind a power bar"
