"Geoffrey S. Mendelson"

The real problem was not that the NTSC system did not have the
autocorrection
that was in the original design and used in the PAL system. The real
problem
was that there was a knob on the TV set that could make everything change
color.

Even with the early 1960's transmission errors, and differences between
the actual colors of various sources, if the color control was set and
left at 'about right", it always would have been a watchable picture.

The problem was that almost no one had any clue of how to adjust it
properly,
and most were set and left in a very wrong postion, while others were
being constantly misadjusted.

All of the TV magazines, science mags, etc had articles on how to properly
adjust your TV set, and I'm sure that for everyone who read and followed
them, there were 10 times the people who didn't.

It was really bad in area where there were many TVs, such as a department
store.
For some strange reason, the cheap TV's were never adjusted properly and
the
expensive ones always were. :-)


** Most any TV set has internal adjustments for colour quality as well as
the usual external ones. However, each maker has their own ideas of how to
set the colour balance ( or colour temp) of a screen - possibly to be
technically accurate OR to look " nice " to most viewers.

Means that a row of different TVs in a shop all look different.

Baffles the brains of nearly all potential customers who insist on the
totally specious notion that they can immediately decide which is the best
by just comparing them with their eyeballs.

A similar nonsense goes on with stereo speakers and other bits of audio gear
too.

You have go NO hope WHATEVER of convincing anyone that merely looking at
a pix on a screen or listening to a pair of speakers is NO WAY to tell how
good either is.
