I have some questions about CRT cataracts. I was wondering if roundies show cataracts more than rectangular type CRT's? Does running the set prevent or stall the onset of a cataract? I recently saw a Shango YouTube that mentions cataracts happen more in a humid environment than a dry climate. Is that true? Which brand has more cataracts, RCA or Zenith? I understand that it's cause is a breakdown of the PVA material used in bonding the safety glass piece to the front of the screen. Can a B/W tv have a cataract? Just curious. Sony brands seem rare to have cataracts, but maybe that's because there not 50 some years old.
