Carefully slide a plastic spudger under the black strip of plastic on the far side of the ribbon connector housing.

When working with electronics, it's important to choose a tool that's ESD-safe to avoid accidental damage to the device. The regular black nylon spudger or a plastic opening tool should be used whenever possible.

Lift the black strip upwards. This will release the ribbon.

Slide the ribbon out of the connector.

Repeat this step to release the other two ribbons.

You will need to remove the tape from covering those connectors, too.
