    image.jpeg as you can see in the picture, the screen is no longer filled with the image, it has shrunk and now it is curved at the sides, what is going on?!

    The CRT is starting to fail, I forget which part exactly (flyback transformer?).

    Defo looks like the EHT/analog board is failing try checking for Bad capacitors or out of spec passive parts (like resistors etc) worse come to worse you will need a new flyback transformer

    Ok thanks, I read somewhere that a sign of a failing CRT was a green hue starting to appear in one of the corners and unclear images while warming up - which I've noticed prior to the shrunken image.
