I could see a design goof up if the bad CRT's from Zenith stopped shortly after 1992-1993. However, this continued throughout the rest of the 90's at least. Every 1990's Zenith or Zenith made TV I've come across had a weak CRT in it. The one exception was a 27 inch Sentry 2 from 1992. From 1993 onward: bad CRT's, and not just the 27 inch ones. 19 inch CRT's, and even 36 inch CRT's... all weak.
Also, not too long ago I found three JVC TV's from around 2003-2004. not only were the CRT's shot, I couldn't adjust the G2 voltage to brighten the picture very much. The flyback's themselves had something inside them limiting how much the knob could turn. I could turn that knob maybe 1/4 of a turn in either direction.
Finally, A Philips TV from 2005 that i worked on had a "feature" to make it shut down if the screen was too dim. That sure as hell wasn't a cost cutting measure!
EDIT: Also, if a company is trying to save money, why not take a reliable design and stick with it for as long as possible? Why spend the money designing a new chassis and CRT every year? Change the case and update the look/features, but keep the important internal electronics the same.
