New problem from older thread http://forums.techguy.org/hardware/644320-schematic-help-connecting-wires.html
thanks for all your help, i finally got the connector on the back to operate....
It finally clicked that I had to keep the connections closed in order for to operation to take hold.

Now the only problem I'm having is connecting my xbox 360 to it via the vga adapter.
I have wired up the db-15 rgb2 output to the same pin 1-15 to a hd-15 vga plug.
I plug in the xbox to the adapter and nothing. Doesn't do anything.
I might be missing something, but I'm not sure so I included all the pages that have anything to do with that port.











and some pictures of the little adapter I made

Did you connect pin #1 to pin #1, pin#2 to pin #2, ... pin#15 to pin #15 between the two connectors in your adapter or did you match up the signal names for the pins?

ok, so far i've got this layout from the monitor to the vga female.
1 Red volt to 1
2 to 2
3 to 3
9 red ground to 6
10 to 7 11 to 8
12 h sync to 13
13 v sync to 14

and above that do I need a monitor ID of any kind?

You may want to add the green ground (VGA 7 - Monitor 10) and blue ground (VGA 8 - Monitor 11).

I can't tell from the connector information how the ground reference is established for the TLL level H & V sync. You may need to connect pin #10 of the VGA connector to either pin #9, 10 or 11 of the monitor connector.

I had a chart many years ago that described the ID bit configurations that Identified the video mode of the monitor. I don't have it anymore though. You may try leaving the ID bits unconnected for now.

yeah what i ended up doing was purchasing a vga to rgb5 cable.
so hopefully that should take care of everything and i wont have to use that odd "vga/rgb" connector.
