Moog Voyager touch surface issue ??

[elektrovolt]

After not having used my Moog Voyager for a few years I took it out of its case and while playing, I noticed that the touch surface did not work anymore.
I was going to open this thing for oscillator calibration anyway, so I checked if maybe some ribbon cable had come loose.
Everything looked fine so I tried disconnecting a few ribbon cables.
When I disconnect the ribbon cable at #1 or #2 the touch surface works again so the panel is not broken so it must be something else.

Could someone help me with this? An expensive repair at a Moog service centre is not really an option due to some financial issues, that is why I am selling the Voyager too..

Also I noticed that one trace on the jacks board was cut (ENV GATE). I soldered a small wire to repair the trace. I don't know if this is normal?
