Combos comprising a display and a video recorder, which avoid a very bright image when switching from a standby recording mode to an on mode. In order to reduce cost, some combos include only one video circuit which is used by both the television and the video recorder, and which notably controls the level of its output signals directed to the display. This control is realized using a feedback loop that provides a feedback signal from the display. To avoid displaying a very bright image when switching the combo from a standby recording mode to an on mode, an amplification control circuit progressively revives an amplifier of the display.
