    Over the past couple of weeks a light grey line with a darker grey line underneath scrolls down the screen, sometimes it goes up! This happens on all 5 channels (I don't have digital or satellite equipment).This doesn't happen all the time which suggests to me that the fault may lie with the transmission and not the TV. Can anybody help please?

    This could be a transmission fault, but more likely to be a TV fault, the suspect being any large electrolytic capacitor. I don't know the individual layout of this set, but the first one to look for is the "smoothing block", which is a collection of two or more electrolytics within one aluminium can, with multiple connections directly onto the printed circuit board. Any dried up white "gunge" seen spreading onto the PC board topside will give you a clue which capacitor might be faulty.
    But beware if you try and repair it yourself, because it is quite an art to remove any multi-terminal component from the PC board!

    When was the last time you were inside a TV? :rolleyes:
    Modern sets (of which henlistons is) don't use dual-canned electrolytic capacitors these days.
    Main smooothing capacitor failure in his model is extremely unlikely.
    I would try a portable TV on the aerial as a first test.
    Do you have cable TV?..........I know you said you did not have digital or satellite.
