Over the last 4 or so years since I bought my televid 65 scope I have had to have the eyecup replaced 3 times, as the plastic tabs that connect with the indents on the 25-50 zoom eyepiece were loosening then breaking. Today I received another replacement from Leica UK, this is a modified version which has been strengthened - Leica have obviously realised there was a problem and changed the design to rectify this... Hope this post will help anyone else who has the same problem...
