DJI insp 1 gimbal fail initialize completely and transmission lost (SOLVED)

Upgrade app to latest and checking all OK, all was fine. When restarting the craft a second time the gimbal start initialize and comes around at first but then just hanging there. At the same time image transmission lost. See video.
Tried:

- Another X3 which is working. Stop at the same place. (X3 and gimbal OK)
- Checked the connectors > gimbal on the craft. All good.
- Checked the connectors between craft > gimbal mount all OK as far as I can tell. dismounted the card from the craft and the 2 cables.

Before I send it to DJI, anything else to check?

Thanks!

HOLY COW! I spent several hours and it was just that.. Learning as long as flying DJI. THANKS!
