My Bush 1473T TV has suddenly (fine one day, faulty the next) developed the
following fault:-

On both normal pictures and teletext, the red, green and blue appear to have
separated vertically e.g.

On normal pictures, some items on screen have coloured, vertical 'outlines'
leading to a 'blurred' effect. Also, sometimes, on normal pictures, a red
line is visible at the top of the screen, and a blue one at the bottom of
the screen.

On teletext, white text is displayed three times, once in red (above and
behind white), once in white and once in blue (below and behind white).
Yellow text is displayed once in red (above and behind), once in yellow etc.

Anyone know what the problem might be, and whether it is likely to be a
economical repair?

TIA.
