undefined's answer with NullPointer check and set timeout :

private void turnOnScreen() {
    PowerManager.WakeLock screenLock = null;
    if ((getSystemService(POWER_SERVICE)) != null) {
        screenLock = ((PowerManager)getSystemService(POWER_SERVICE)).newWakeLock(
                PowerManager.SCREEN_BRIGHT_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP, "TAG");
        screenLock.acquire(10*60*1000L /*10 minutes*/);


        screenLock.release();
    }
}
