what's up with old tvs and cable channels?
 
got an old..... Sony Trinitron. electronic tuning, so it's not that
old, but mono. switched to CATV input, it gets (analog Comcast)
channels 2-40 perfectly, gets nothing from 41-99. Now that's just too
clean a break to be anything other than design, so does anybody know
what gives?

What gives is that your TV tuner was designed for an earlier era.
There have been at least three generations of "cable-compatible"
frequency sets, and your TV evidently can't see whatever set your
cable uses. Are you sure your TV tuner is set to "CATV" or "CABLE"
versus broadcast?

There used to be little boxes available that could block-translate
frequencies...call the cable company and ask about a "block converter"
for your set.

Does it have separate VHF and UHF inputs? If so, you may need to use a
splitter and a 75/300 balun to get all the channels. My mother has an
old RCA that works if you do that.

Also, channels 95-99 are a bit odd, and many will not pick them up,
except possibly 98 and 99.

Here's a nice table listed by frequency, so you can see how odd cable
channels are set up:

CATV is not cable TV, it's community access television, they're different.

No, it's "Community Antenna TV". In other words, the origins of cable,
where someone would stick up a big antenna and share the signal. Eventually,
the antenna part was forgotten, and it was simply the feed system that
became important, ie "Cable".

So the fact that the tv set would be switched to "CATV" is not an error
on the part of the manufacturer, and does not suddenly bring in the local
access channel. It means "cable", or to look at it differently, "cable"
is slang for CATV.

maybe you could use a more modern vcr with the hi band tuner connected
to the tv to view those extra channels. probably cheapest

Yeah, that's what I did. lots of orphaned VCRs looking for a home
nowadays.

Your TV is too old. You will need a converter that will convert the upper
channels to a channel that the TV can be tuned to see. These converters are
starting to become very difficult to find. Many of these older TV sets have
long disappeared!

Televisions that old wouldn't register channel numbers above 13. He's
talking about 41 through 99.
