I asked about this last year and was able to get a Janet and John guide to disassembly which enabled me to sort the broken strings as they occurred.
This weekend I started to take every blind unit off and refurbish them. They are only 2 years old! The problem for me has been the springs on the white blackout blind strings. These are at the bottom of the frame and suffer from a damp environment due to their proximity to the base of even a partially open window. AND they are ordinary steel. They corrode and break into pieces in some cases, but also leech rust onto the string as well as create a rough surface to saw through the string as it is tensioned in use. See picture.
So because the other end has plenty of excess I pulled the string through and cut off the weakened section and I replace the springs with new stainless steel ones I bought off the internet. I then coated as much of the string as possible with beeswax and sprayed the plastic running surfaces with silicone. Whilst out it is also easier to give the blinds themselves a deep clean.
