How to use TFT PI on DSI with CB2

[Kostt3d]

Good morning I managed to get the CB2 to work with a TFT PI 70 on manta m8p but impossible on the M4p. the screen remains black. The assembly instructions for the dsi cable on the 2 manuals are reversed on the TFT screen; I guess the one on the Manta M8p is the correct one with the GND on top and the 3v3 on the bottom. Who can help me please?
