Abstract
In a color television receiver including a color kinescope and plural kinescope driver stages, a control circuit is included for inhibiting the operation of the driver stages for a short interval after the receiver is energized, particularly under "hot start" conditions, to prevent disturbing artifacts from being displayed by the kinescope. In an illustrated embodiment the driver stages are disabled in response to a control signal applied to a bias point common to the plural driver stages.
