FZ50 Flex connector question.
i am attempting to clean the sensor of a DMC-FZ50 and although straight forward i have come across a few connectors which attach the top panel to the PCB that i am unsure how to remove the cables from . Photo below. There seem to be no moveable parts on these and yet the cable is tightly inserted. Anyone know how i release these properly as i dont wish to damage anything . Many thanks .
