Thank you all for your comments! I do have the service manual pdf.
Thank you! That's very useful!
OK so I think I found the problem. Somehow, both upper and lower first curtain ribbons had jumped the pulleys! Get these back into the pulleys. Simple: Right? Or so I thought! This was a week's battle. The battle actually started last year
I was finally able to get them in place.
So I'm done!
No wait.... I don't think I can take pictures with it yet...
Thanks,
A bit of practical advice after trying for hours to relocate the curtain cords of the first blind back on the pulleys top and bottom of the second blind drum ( shown in red in the photo above). Despite my repair manual saying it can be done without further dismantling, although it is fiddly( to put it mildly!), there is a reason it is near impossible. There are two vertical guides intended to retain the cords to prevent them dropping off the pulleys should the blind tension be less than optimal, and so the cords have to be physically pushed between guide and pulley to get them back on, at the same time as guiding the cord downwards from the other side of the pulley to engage the cord in the pulley groove. I found, having tried the 'no more dismantling' method it is MUCH easier if you remove the self-timer mechanism first. This is simple-remove the two fixing screws that secure the lever that is at right angles to the shutter release shaft ( it triggers the bottom lever at the side of the mirror box) , and then remove the two fixing screws that hold the self-timer in place. This gives clear access to the section of the two pulleys with the problematic guides. The cord can then be pushed down between guide and pulley, locating the cord quickly. Just ensure you have tension in the first blind at the same time otherwise the cord(s) will drop off again! Ten minutes work against hours of frustration-worked for me.
