What does NTSC stand for, and where can people get a color bar?
Sorry folks, I could not resist the temptation. I used to work in TV
testing & we used to say that NTSC stands for "Never the same color"
As for where you can get a test pattern, several test instrument maker
make dedicated test pattern generators for TV. Some general purpose
waveform generators also have the capability to produce TV test
patterns. Here are some examples, you can find many more on the web:
AMT CB203A Colour Bar Genenrator from Abletron,

Much cheaper, if you have a computer with a composite video or SVHS
output (some laptops do), you may be able to create your own pattern of
vertical bars using any program you like and use that as a test for
your TV.
