popping noise when switching tv channels


I have a Time Warner cable box. Sometimes when I switch channels there is a loud popping noise but not all the time. The sound cable(coax) from the cable box (Scientic Atlanta 3200HD)feeds into my Mcintosh MX135 pre/pro. All my components are fed power from a Panamax 5500EX surge/AC regeneration unit.
Any thoughts on what can be done to eliminate this noise??

The sound cable(coax) from the cable box ----try an optical cable.

But it sounds like you have a cable ground problem, might even be intermittant with the high AC load due to Air Conditioning etc.

Build yourself a "magic" to lift the ground on your incoming cable with $10 in parts from radio shack.
