    areal ? arial? gosh you must mean aerial, why do so many people get this wrong?

    Right rant over, have you got a speaker or something magnetic near these old CRT tellies? This can cause colour impurity problems, LCD tellies are not affected by this.

    Good post

    As this is the Freeview forum, are you talking about old TVs connected to a digital box, but the LCD TV connected to the aerial direct? If so, then I suggest that the SCART cable is probably not properly connected at the end plugged into the box.

    Or

    (1). if it's the same STB connected to the two CRT TVs, the STB is faulty

    (2) I believe that effect can sometimes happen if the STB is set to output RGB when the TV can only deal with a PAL input (as they're both old TVs, that must be a possibility here).

    Some really old CRT TVs had incorrectly wired up RGB SCART sockets, which resulted in a green wash when attempting to view an RGB signal. I had this problem with a 1988 Panasonic TV once.

    The fix was to put the STB or SCART socket into composite mode.

    Yes. I had exactly the same issue recently. I bought the in-laws a cheepo freeview box from Argos. When I set it up the picture was green.
    I went into the output setting for the box and swapped from CVBS to RGB (or vice-versa).
    Excellent picture now.

    STB = set top box, e.g. your Freeview box.

    Digibox = digital satellite receiver for Sky Digital.

    What is going on here in NOT clear ........

    Presumably, several tv older sets are being plugged into a Freeview receiver?

    A "coloured" picture is probably due to a poor SCART connector lead. The correct picture needs all 3 colour component signals (R, G, B), and if 1 pin (of 3) is missing the picture will look coloured! Scart leads are notoriously bad, make sure the connectors both ends are FIRMLY pushed in!

    If this doesn;t work, try changing to CVBS instead of RGB. That's the complete colour signal on just 1 pin!
