a1316 cable all-in-one doesn't work

I have a monitor Apple A1316 (with mini display port - mdp) and It did not work. Then I reconnected mdp cable to my video card the picture is appeared and monitor worked normally.

But recently the cable stopped working and I could not find new cable all-in-one for aplle a1316 monitor. I bought mdp cable and I opened monitor. I deleted magsafe cable and I deleted usb cable. I found logical scheme for mdp cable (20 pin), but i can not find logical scheme for 30 pin apple connector to LCD display. Then I solder mdp cable (20 pin) with 30 pin apple connector (using multimeter) - the aplle monitor started show a blizzard with the outlines of the desktop windows. Have anybody scheme of 30 pin connector for LCD display?
