What do you think could be the issue?
Only Pin 4 has 2.66V - no idea what this is for and if it's normal. EDP_HPD_PANEL_R Page 19. LCD/LED PANEL Conn. All other pins correct V.
Tried 3 different screens. There is picture. No physical obvious damages or components.
Hi ThienBui, I have swapped with another BIOS chip from another Surface Pro 7, 1866 same model. Same issue. The serial number is most likely not in the BIOS chip. Any recommendations?
