Great! That's probably what we all ought to try :-))
Many HDTV sets these days actually run off of low-voltage DC, often 12-20 volts or so. I shopped for one which would run just fine from 12VDC, and found a small Magnavox model which has been just great.
You can expect that a 20" model will draw about 60-70 watts (5-6 amps @ 12V), while a 26" model may draw twice that.
If the model you want needs, say 18VDC, you can get a small power supply designed for computers which will provide the needed voltage. Lind Electronics makes such devices, they're of high quality, and can provide the needed voltage even if your batteries are low...as they're bound to be if you watch much TV :-)
Look for TV's which have a "car adapter" port, or separate DC input, or come with some sort of power brick.
