The sets that are even more than about 10 years old will soon wear
out, and also including the wearing out of their CRT's. Replacement
tubes for any TV that is more than about 5 years old is hard to find
these days. And, if you do find a replacement tube (CRT), it will
generaly cost more than the equivelent new set to replace.

However, the equivalent new set won't exist if CRT sets are not being
built.

Also, the goal of the makers is to get the entry level TV up around $1000,
so there will continue to be lots of demand for the more reasonably priced sets.
If the replacement sets (of new technology) cost this much, re-tubing old sets
will begin to look a lot more attractive.

I predict some hard times for the folks who give up making affordable sets
in the hope that consumers will be happy to pay several times as much for new
technology.

In a number of years the broadcast system will be changing to digital
only. Then it will go on to HDTV type broadcasting. A converter box
will be required to see the pictures on the older sets. There will be
a point where the older sets will soon die off, and then the users
will be forced to replace them with newer sets, if they want to be
able to watch TV.

As has been pointed out, the mandate is only for over the air broadcasting.
Since many use cable and cable boxes, or satellite, they are familiar with
external tuners and equipment. There is no mandated change for these services,
and no reason for the satellite/cable channels to change for a long time.

I have removed sci.engr.television.advanced from the groups list, since
this really isn't about the advanced television standards system (even though
I brought it up), so is off-topic to the group.
