820-01326 no image after water damage

[yobad]

I have 820-01326 little bit water damaged but no image on screen.
Working on the external screen.
Water damage on LVDs cable, i did a Diode mode reading, can't find any short. It maybe the MUX but i don't have a donor board, it is the same of A1707 ?
Also Is the lcd the same of A1707 to test the motherboard ?
Thanks for the help

Try using 01041 schematic.

GMUX, maybe video connector/cable damaged too.
Replace all them and you can test with A1707 screen.
