820-4924 No keyboard/Trackpad/Camera/Thunderbolt

[ALB-Repairs]

Hi
Got an 820-4924 here, no signs of corrosion/ liquid damage
The keyboard and trackpad first off worked intermittently, but now have failed completely.
Diagnosis picks up issues with both thunderbolt and the camera, I did have one run where thunderbolt didnt show any problems so again id assume some intermittency.

I have a feeling these issues are all tied together somehow but im unsure how.
Any ideas?

Checked supply voltages to any of these devices? Checked if camera is really dead in OSX?

Main thing im concerned about it keyboard and trackpad for now.
Power to the keyboard and trackpad is all good.
Diode mode on the trackpad connector checked and all looks good compared to a known good board

I assume you tried another trackpad cable, they are very common failure.
