Ok, here is what I had to do after trying every way that I could think of... I gave one last combo a try and this was it:
1) Unplug power on screen / take battery out of remote
2) Plug screen back in
3) Power screen on BY BUTTON ON MONTIOR - NOT REMOTE - this was the step that I didn't ever try before
4) Put battery back in remote and push 588998 while blue lights are still on (pretty much as SOON as you see a VGA picture on the screen)
5) Poof, the number entry screen appears. I used 1270210 to make it auto power on.
The important thing I learned was that this has to be done FIRST THING after the monitor has been powered on with the button on the front of the montior. I don't know if the removal of the battery is really necessary. I read about that in another post, and it worked when I did it. After punching in about a thousand combos, I'm just happy it worked and didn't feel like double checking to see if any of the steps were unnessasary
