Have you tried a known good screen?  What is the phones history?

You should not have touched chestnut. Now you have added variables to your repair. I have measured different voltages on that line and yours is acceptable.

You need to diode the connector and find what line is missing. If all the pins measure right I would try another meson than cumulus.
