My mother (hence your truly gets to fix it - she is responsible for more posts on geekzone than me...) has had two set top boxes and a router die for no obvious reason. And they are dead. No power lights when plugged in.

The only common factor is that they were all (via a multibox) connected to the same powerpoint when they died - though not at the same time, this was over the course of a couple of weeks.

The mutibox has been replaced as I thought that may have been the problem, but another STB has just turned up its toes.

I suspect the powerpoint may be faulty, though am not sure. Both multiboxes have surge protectors that haven't tripped. And other devices in the same multibox (notably the TV) is absolutely fine.

Mr Electrician will be called as soon as the long weekend is over, but was just wondering how he will actually diagnose if there is a problem with the powerpoint. Clearly I will not be poking multimeter prongs into a 240V powerpoint personally.
