<p>Bending of vertical bar type information such as displayed on the screen of a kinescope (24) as a tuning indication, is due to kinescope beam current variations. Means (58) are provided for reducing the beam current threshold level of an automatic beam current limiter stage 44 to a lower threshold level or for otherwise (23) reducing the beam current, whenever vertical bar type information is to be displayed.</p> |
