Sony SSM14N5U Trinitron crt swap

[MX70]

Hi all, I've had this Sony SSM 14N5U industrial monitor for a few years that I got for free and it's in good working order except for a noticeable screen burn. It was a security monitor used in a store and probably not turned off ! I Would have probably tossed or parted it out but being a multi system monitor, is useful to me. I'm not above swapping out the crt , but what would be any issues to watch out for? The crt number is M34KBE11X. It is a UK built monitor made in November 1998, sold new in Canada. The picture is still sharp, bright and colour is great but with the burnt in image. Thanks for any advice !
