Only one button not working... newbie question

[Mario.Semiglia]

Hallo guys,

I am trying to make this work but I cant, I used 4 color wires to extend the Contrast button and the + and - buttons of this tft screen.
Menu Button works perfect, and plus button also works perfect, the only button I dont manage is the minos.
In my picture minos is the red wire. I already tried sodering an independent ground and power to that button but it wont happen anything on the screen when I press it. I used my multimetter and the electricity definetly flows when I press the button... it just doesnt do anything on the screen.

Have you tried the opposite side for the red connection....

yes I did, I actually tried every single place wich my multimiter told me . On the botom right on the top up, on the lower right hole, on the top hole, I could not make that buttom to work so I even tried the left leg of the resistor .
Than I though, maybe I have something foreshortened, so passed an eraser and the result is a catastrophe, it seems that in the process of removing the actual button i pealed some of the pcb that I shouldnt, the pcb looks really messy now . I did use my multimetter to check for bridges, did not find any... anyways this is my messy pcb
