I repaired mine.
I dont think its the same make but same principle
take all the outer frame down
rethread the strings then what I did where the tension springs hold in I used a gluegun to help them stay.
its a long fiddly job but cheaper than a new one (here in Belgium)
The spares are much cheaper in the UK so y Zains Pops idea first.
Mine looked worse at first you just have to sit back and work the route out for the strings/cables
Dave sorry I just reread you post.
on mile to take the frame off you remove the winding handel.
also there are grills all round it remove these and under that there are screws remove them and the hole frame comes away.
on the Rapido you also have spot lamps mounted in wood.
to remove these you have to pull the spots out then remove the screws holding the wood.
