I thought that there was some definite economization-to-death in the later years. From like 1995 until their demise, was there any meaningful enhancement to NTSC tube TVs? There were minor enhancements in on-screen display, flatter glass fronts, and maybe the addition of S-video inputs, but there wasn't really much that could be leveraged as a "premium" set that could demand a higher margin except for maybe a Sony Trinitron. There was no meaningful "Replace your 720-line set with a 1080- or 2160-line one" sales pitch. The obvious way to compete is to go full Madman Muntz and cut every possible corner. I recall in the early 2000s a fairly newish (at the time) RCA 27" tube release the magic smoke, and the discussion on sci.electronics.repair was very much "oh, that chassis design is all but guaranteed to fail catastropically when it does fail, may as well buy a new set". I don't doubt that group had several thousand man-years of repair experience, and they had very little positive to say for any set made after the Carter administration.
