I believe the purpose of these caps (and sometimes a resistor) is, as Phil suggested, to either prevent RF interference from coming in on the AC line, or from the set putting RF out on the AC line. The caps are way too small to have any effect on 60hz AC voltage spikes or surges, other than the very high frequency noise. IMO.
