Checks and expected results

Before you repair it

Record the LMU and G HUB versions and whether the failure occurs before the menu.
Finish any device or firmware update before considering a restart or temporary closure.
With LMU closed, test a launch with G HUB closed only if it is safe for your hardware setup; confirm controls before driving.

How to confirm the result

Compare startup behavior under the same conditions. If the result consistently changes with G HUB, use Logitech guidance for the installed version and hardware.

Repair limits and when to stop

This is community-derived diagnostic guidance, not proof that G HUB causes every black screen. Third-party updates remain manual; closing G HUB may affect device features.

How PitMedic recognizes it

LMU launch failure with G Hub running and no stronger signature; only suggest when installed version/state is known.
