video power on during blank screen?

Archived from groups: alt.tv.tech.hdtv (More info?)

One of the channels I watch only broadcasts over satellite during certain
hours, mainly news in the morning, noon, and supper time. If I leave the TV
on to this channel, it will go blank once the station stops using the
satellite.

Also, my satellite service has a number of radio stations which have music
but no video.

I'm curious: is the video power on during these periods? On my current set
(a DV Sony Trinitron CRT) I see a slight glow to the screen compared to when
it's actually off.

Specifically, I'm wondering about my planned micro-display HDTV (probably
either lcd or ILA). Will the lamp still be burning up its limited allotment
of hours while I'm listening to music over the satellite?

Yup, the lamp is still burning. Think of the mirror in DLP or the LCD in LCD
projection as a shutter that turns off (black) so that light doesn't get
thru. The lamp is still running.
