Hi Tasha,
This is a random puzzle, but here are a couple of combinations which you might try which have worked for others:
a) Top left up and all the rest down.
b) All up except the top right is down.
If that doesn't help, try it switch by switch. After clicking each switch individually, step back from the puzzle and see which area of the floor is lit up now. That way you should by trial and error be able to work it out (cross fingers!).
