Baxi boiler doing this…

Hi,
Our boiler keeps doing this (click on the image at the bottom to play the video)…

When I move the control section it connects and fires up.

Obviously a dodgy connection - is it an easy DIY fix? Find the dodgy wire and replace it?
Will it need that whole section replacing?

Could be a dry soldering joint on a component.
