Lost forward sensors after rebuild

[g1ant]

I repaired a crashed Mavic Pro quite successfully. The plastic air grill had also taken a bash from the gimbal being pushed back into it. This made the new fan noisy as the air grill caught on the fan so I decided on a middle shell replacement.
Its a fiddly swap out soldering the front legs off but a reasonably straighforward operation otherwise.

Once I had everything put back together I have a complete failure of forward sensors. If I try to calibrate them on a pc there’s no signal from the sensors so no blue box on the screen.

I have double checked the ribbon cables on top of the gimbal and they look ok.

Is there anything else I should look for?
