Hi Tomas. I would check the following:

* Verify the resistor on the 45_LCM_REXT line to insure it meets specifications. This resistor is responsible for properly biasing the MIPI/DSI interface circuit.
* Verify that R0206 is within specifications and that C0201 is not shorted. R0206 pulls up the RESET_1V8_L line to 1.8V.
* Verify the internal continuity of the RESET_1V8_L line 1.8V line by testing between TP2508 and pin C2 of Chestnut. This will require that you remove U1501. If this line is broken, then you will need to run a jumper.

Let me know what you find.
