I just replaced the power/inverter board on a Dell 2005FPW monitor and now have two extra screws. Can anyone tell me where they go. I first remove the stand and then removed the four black screws from the back. After unclipping the bezel, I removed four more screws from the sises of the monitor. Finally, I removed the four screws for the board. At some point I removed the two extra screws but cannot determine where the were originally.
