Hello,

We operate a HB400 Wire EDM machine but thats not important, the 30 pin display cable was ripped from the back of the display of the controller. I ordered another 30 pin connector (FI-X30HL) to connect the wires to. The company who produced the display (szzcoding) is some chinese manufacturer of displays who has since dropped off the map and will not respond to any means of contact. What I'm asking for here is any advice on how to assess the proper placement of wires, what is the best way to go about it without causing any permanent damage to the display, or if I need to get more information on the display circuit board. There are only 24 wires coming from the sleeve, with 23 going into a 30 pin connector which plugs into the back of the display and the 24th being the only black wire is taped down the side. The 24 wires connect back into two sets of LVDS cables in the image attached.

The wires are marked with either 1, 2 or 3 black or red marks.
6x Yellow wire: 1 red, 2 red, 3 red, 1 black, 2 black, 3 black
6x Orange wire: 1 red, 2 red, 3 red, 1 black, 2 black, 3 black
3x Grey Wire: 1 black, 1 red , 2 red
4x Pink: 1 red, 2 red, 1 black, 2 black
4x White wire: 1 red, 2 red, 1 black, 2 black

The first thing I would do is to get a DMM set to continuity test.
Find out which pins are common to GND. See if there is a pattern with the cable markings.
Also, when the cable was yanked out of the connector, they would have come out in a certain grouping with respect to the connector, if they were not disturbed.
