MBP screen has *snow* after sleep

I'd be calling Apple back quickly about this.

Hello all,

I sent my MacBook Pro in for a logic board replacement and when I got it back I noticed that when I let it sleep for five minutes or longer the screen would turn to what looked like "white noise" after wakeup. The "static" will not leave without a forced powerdown and reboot, and will only reappear if the MBP sleeps for longer than five minutes.

I tried a reformat and that seemed to help but the problem returned. I didn't install anything abnormal and certainly nothing I didn't have on it before I sent it in for repair.

What is causing this?

Nothing normal, that's fur sure. I'd be calling Apple back quickly about this.

It's got to be the logic board. Back to AppleCare.
