Imac g4 dvi conversion.

[YeetGuy33]

so I would like to convert my 15 inch 800mhz imac g4 to dvi, but I cant find any pinouts that make sense. The one from dremel junkie doesnt label all of the dvi pins and I dont know if there are any tutorials of my specific version or any pinouts I can understand I also dont understand the power solutions.

AFAICS Dremeljunkie’s pinouts label all of DVI’s 24 pins for digital signals — including those that can be left unconnected. The five pins at the far right of the DVI connector (numbered 25-30 in DJ’s pinouts) are for analog signals. You don’t need those.

I am trying to do the exact same with a 1GHz 15" and that pinout truly doesn't make any sense!
It's very unclear what you need to do!

This thread is recent and must not die! We need actual information about what to do with the wires in the gray cable!
Some info on the inverter would be useful too even though I think it's all the same as 17" 1/1.25GHz.

What the pinout has to say about the inverter cable doesn't even apply as there is an orange wire in mine!

Apparently 15" 1GHz and 17" 1/1.25GHz are swappable displays https://forums.macrumors.com/thread...2-0-lcd-repair-17-screen-on-15-board.2281608/
so the connector pinout has to be the same, but I have already disassembled my connector!
And that does absolutely not mean wire colors have to be the same in the same spot!

I have wired the thing as if it was a 17" 1/1.25GHz because I noticed that blue and green from grey cable were connected together internally to the display (measured using multimeter) and on the other side so were yellow and orange.
My MacBook is able to tell I have an Apple iMac 15" 1024x768 display but the LCD doesn't appear to work, and i couldn't get the backlight to work.
The display originally was 100% OK

I still can't get the LCD to work and my amp draw seems like it could be just the small cables, so there has to be a short.
