2136001 9326129 PCTABS00028 A diagnostic method and apparatus for a cable television interdiction system is provided. One or more diagnostic modes each corresponding to a particular problem or state associated with the interdiction unity may be entered into by the interdiction unit. The cycle of disabling the television signal provided to the receiving apparatus and pulsing either or both the television signal provided to the receiving apparatus and/or the LED is repeated until a transaction is received from the headend cancelling the diagnostic mode. Thus, the pulsing of the television signal provided to the receiving apparatus alerts the user of the receiving apparatus that a problem has occurred to the interdiction unit, and this information may be provided by the user to the cable television operator. Likewise, the pulsing LED coupled to the interdiction unit may alert a technician working on the interdiction unit as to the cause of the problem. In a preferred embodiment, the LED may be located on a tamper override module (TOM) (400) inserted into the interdiction unit by a technician in order to service the interdiction unit.
