A method and apparatus for localizing a source of faulty color operation of a color television receiver having an image producing element and a chassis providing signals to the image producing element through sockets in a chassis output signal connector removably received by an input signal connector on the image producing element. A plurality of visual voltage magnitude indicators are provided to visually indicate at least relative voltage levels of an applied signal. Each of the visual voltage magnitude indicators preferably comprises a light emitting means such as a neon glow lamp variable in brightness in response to variations in magnitude of applied voltage levels. Individual electrical connections are affected between each of a plurality of the sockets of the chassis output signal connector and respective ones of the plurality of visual voltage magnitude indicators with the chassis output signal connector removed from the image producing element input signal connector. A source of faulty operation of the television receiver can be thereby localized to either the image producing element or the chassis through manipulation of the customer color controls on the television receiver.
