Peugeot 406 MFD Repair

Trying to repair the Type C or sat nav Multifunction Display out of the 406, its a common fault with these that they loose lines, although this is the old one out of the car and it has been replaced i would like to be able to repair it given how rare and expensive replacements are.

I tried to repair this display by using a heat gun to restick the ribbon that goes to the LCD, i assume that is why some lines are dead is because the ribbon has detached somewhere, after trying to restick the ribbon both on the LCD side and the board side it still doesnt work.
Anyhow its an old spare LCD so im willing to try different techniques to get it working right, any suggestions on how to repair these is welcome.
