First time I've ever seen a picture in this forum and that's it good god!
Last weeks S** I***** drop out was not an error according to good sources, it was a deliberate attempt to locate and update older boxes not paired yet and caught many people out. If a box goes blank then the customer phones in and now eligible for a wondrous new "paired" box.
This is not the end of the "sd" problem, in fact, it's just the start.
