ABSTRACT:
A television simulator for DST transformers including a hood which is intended to be connected to a cathode ray tube of a television set. The television simulator further includes a first power supply connected to one of the terminals of the primary of the DST transformer for supplying power and a unit for simulating the final line stage of the television set. The unit for simulating the final line stage of the television set presents a first input signal from a microprocessor, a second input signal from the other terminal of the primary of the DST transformer, and first and second error output signals towards the microprocessor. The television simulator further includes a control unit for a display screen, the control unit receiving a signal from the microprocessor and also providing an output signal towards said display screen. The television simulator also includes a voltage divider unit which is connected to the hood of the DST transformer and which has an output signal towards the microprocessor and a second power supply, such that the display screen shows, when the transformer is functioning incorrectly, the type of failure which exists, and, when the transformer is functioning correctly, the proportional voltage supplied by the DST transformer.
