Is this pin important to the system to work?

I was removing the flex cable for the retrogem mod and I remove the pad from the system and have a black screen. I pretty sure its pin 185 of the IC140 I can even see the silhouette of the pad can this be fixed and if so were can I run the jumper wire to? Does the connection on pin 135 the last pic look good? I am getting continuity.
