Abstract
A television receiver capable of displaying the condition, i.e., ON or OFF, of the power supply which supplies electric power to an external BS (broadcasting satellite) reception converter, together with the reception level at the BS antenna. The level at the antenna is detected by a level detector circuit (27) according to the output from a BS tuner (23) and displayed on the CRT (36). A power supply circuit (20) which supplies electric power to the external BS converter is switched on by a power switch (46). A system controller (41) detects the condition of this power switch and displays this condition together with the antenna reception level.
