ABSTRACT:
A display apparatus, for instance a television receiver, comprises a cathode ray tube, a first circuit for providing a high voltage to the cathode and a second circuit receiving a gross signal and providing on at least an output at least a luminance signal controlling an electron stream of the cathode ray tube. To reduce stray emission, absence of gross signal is simulated when the apparatus is switched from on to off.
