I am having a whale of a time trying to keep the lights going in the room while searching it. I can't get anywhere.

Have you checked here:
Margie's walkthrough.
Picture level 35.

This is what is stated in Margie's wt:
Click on "Lights 01" and "Lights 02" so you can see in the room.
If you don't perform the actions in a timely manner you will have to press "Lights 01" and "Lights 02" several times until you complete the task
Look on the left side and you will see three computer monitors. Underneath those monitors you have 3 drawers.
Click on the drawer that is in the middle and in it you will find a key, take it.
Click on the brown cabinet that is on the right side. Above the drawers you will see what looks like 2 film reels.
Once you click on that drawer, you will need to use your key in order to retrieve a VHS tape that is inside.
Open the pop-up window that is on top of the monitor, below the wall clock and place the VHS tape in the top part that it says "input"
Press the red "record" button that is on top.
You will see a red dot appear on the monitor, once the red dot disappears press the "eject" button.
The VHS tape will then go back into inventory with a label on it.
Open the window again and now place the VHS tape in the "output" section and press the "play" button that is at the bottom.
Wait until the "power status" bar is FULL and click "GRATE", "LIGHT 01" and "LIGHT 02" in that precise order and EXIT.

Thanks so much! I will try that tonight, probably during halftime of the Packer game. LOL My problem is that I don't "move" fast enough when doing some of the tasks in this game, and this is the first room that needs timing.
