Strange Spots on Trinitron CRT

[wa2ise]

Older American color CRTs the faceplate is stuck on with a silicon like glue. And can be removed by various techniques, search this forum for "cataract". Though none were like Sony's.

If you remove the CRT from the cabinet, don't take the yoke and other stuff attached to the neck area off the CRT, as that will require you do a convergence over again, and that is a PITA.

Be sure to wear eye protection, as CRTs can be dangerous if they implode. A full face shield would be better. And long sleeves and full length pants too, idea is to keep flying bits of glass out of the skin and eyes.

Good day to all,

Thank you! gentlemen for your replies. I've learned something: that Sony also used a plexiglas protection faceplate on some of its tubes - never suspected that.

TV belongs to a friend so i won't be attempting removal.
