Abstract
In a central television diagnostics system, a plurality of remotely located televisions are connected to a central television distribution facility. The remote televisions each have a microprocessor receiving signal quality values and a memory for storing the quality values. One of the quality values comprises a base line measurement value and another comprises a current measurement value. The microprocessor selectively displays on a display of said television a history of said measurement values upon command by a user or service technician desiring to diagnose the status of signal quality at said television.
