I think the very heavy weight of the large screen models lead to them being dropped by their owners. The 27" models were heavy but nothing like the 29" ones that almost without exception had flat tubes. I could never work out why the 29" ones were so heavy other than very thick glass. J.
The frame of the wire mask is particularly heavy.

I've seen the rainbow and misconvergence errors from sets that were dropped. Never knew about focus problems.
