The illustration indicates this connector to be tilted upwards. I did - and broke the female connector. As shown on the right hand picture, the same thing has happened during the dismantling forming the basis for this “ifixit” instruction.

This ribbon should be pulled straight out - not lifted upwards

This part left me in the lurch a bit, undid the top 2 screws holding the shutter in but there seemed more to undo to actually release the shutter.

If you intend to replace the shutter assembly only, you need to loosen it from the “shutter house” (don’ know correct term); (It is possible to purchase new blades only, but it seems complicated, and a shutter assembly costs around 35USD from Asia.)

There are 3 screws; 2 visible on the “top” of the shutter assembly and one hidden underneath some ribbons on the “underside”. Study the new shutter to identify the screws being part of of the assembly and the ones holding it to the shutter house. (3 screws as mentioned)

The power leads for the electric motor must be loosened by soldering (red and black cables).

A ribbon with 4 tiny soldering points has to be loosened with a sharp tipped soldering iron; If you don’ t feel competent; bring it to someone who can do the very delicate soldering - especially for connecting the new shutter assembly.
