That's not how they normally work. When there's no signal, the set is supposed to show a white screen with the tuning indicator at the right scrolling down as it scans for channels. When the green screen happens, it covers the entire screen, even the tuning indicator, which is supposed to be a permanent fixture of the display.

When my TV-400 started to fail a few years ago, I did indeed observe that it would take a few minutes to wake up when you turned it on. Then eventually the green screen became permanent.
