Hey, CRT nerds! Any ideas on what could cause this sort of blotchy dimness on parts of the screen?

There is also a few decades of dust on the tube and the caps (“condos”) might be in bad shape.

I want to apologise for insulting French Telecom engineers. The minitel crt is really nicely designed for servicing and has its own stand built in.

It’s like @cibomahto says: there’s always an 8051 in there somewhere.

@th @cibomahto The Minitels I have are designed by Philips and has an 80C31 in it. Interestingly has an eprom on board that can be used to run ones own code as some did.
