is it possible for x10 signal bridge to fail?

I have several X10 lights which suddenly stopped responding, intermittently, to X10 signals. by turning on and off some 220V appliances, I've come to believe that it's a failure of the whole-house signal bridge, about 10 years old.

Since this is a completely passive system (my understanding anyway), I'm not sure how it could fail, but I wanted to ask here if having it replaced by an electrician is a reasonable effort at problem solving, since I can reliably make these switches respond by turning on 220V appliances?

thanks.
