Suddenly stopped working socket rockets and appliance modules

[geek]

Noticed a lamp was out and changed  the bulb only to find that not one of three sockets i had would work. Worked in it before with no problem, but strange that all three i tried now would not work. Also I have a lamp module and an appliance module that no longer work, and have basically never been used. Is this a common problem? and more important, is there a fix?
thanks for any help in advance.

Have you recently purchased a new electronic appliance like a PC, UPS, TV, or Stereo?  Switching power supplies on devices like this can either generate noise on the powerline or short out the X10 signal.  If so, a special X10 noise filter between the offending appliance and the wall socket is the fix.  (Test an appliance by unplugging from the wall - merely turning it off isn't enough.)

Some compact fluorescent lights can also create similar problems.

....and, what are you using to control them?
