Default CRT screen burn in.

I'd guess the contrast is already cranked up as a default mode, which
is why this TV is showing that much screen burn in only a year,
regardless of what mode it was watched in.

My PTV is 3 years old, and shows zero pattern burn on the CRT faces.
Of course I set up the black level correctly, and add just enough
contrast to make the picture natural.
