: The diagram covers the system block for Intel Sky Lake-U and sub-boards for Kaby Lake-R , ensuring compatibility across multiple CPU generations. Next, check the logic signals: BLON_OUT (Backlight Enable,
Locate the LVDS/eDP screen connector block ( JEDP1 ) in the schematic layout. Check for the backlight power rail ( +LED_VCC or +VIN_BLGND ), which should measure roughly 19.5V. Next, check the logic signals: BLON_OUT (Backlight Enable, ~3.3V) and VCC_EDP (Panel Logic Power, ~3.3V). If these enable signals are dead, trace them back to the source to find blown inline zero-ohm resistors or fractured logic gates.
