Hi.
I think Michael that the problem wasn't so much the introduction of WS tubes but the cost cutting to enable them to be cheap enough. The Philips WS tubes had terrible gun problems, shorts, open circuit cathodes and low emission after a year or so. The Sony Trinitron WS tubes went low emission very quickly. Some of the Japanese CRT's though were OK.
Our Samsung Slimfit 32 CRT set lasted 8 years until it kept loosing it's memory, this was caused by flashover in the LOPT which was very common.
The early LCD sets were grim, terrible definition, blurring on anything other than a still and poor reliability. Things have improved picture quality wise now and HD terrestrial is better than pictures have been for a long time, although I'd still say a decent 4:3 set on 625 in the 90's would probably knock the pants off an HD picture now (probably not 4K though) although it's not easy to compare as the system is gone to do the comparison.
