    If you are feeling brave you can adjust Green drv / ct in Service Menu.

    Maybe you have too much green, maybe you need more red and / or blue.

    Try increasing CONTX to improve contrast in dark scenes.

    Obviously make a note of original settings before you experiment.

    For Service Menu - Try pressing mute on remote, then hold pressing mute once more whilst pressing menu on tv under the front flap.

    Be wary - you could destroy the tv. :eek:

    Bottom line is the CRT ( tube ) is becoming low emission, a common problem with Toshiba face flat tvs.

    If you have a guarantee it should be replaced before it fails completely.

    Contact the dealer that sold you the tv for a resolution. Otherwise use your statutory rights to resolve your complaint. :cool:

    If the TV is green in dark/black areas then it is the beam 'cut offs' that require adjusting not the drives. Reduce the green cut off - but beware it should be a senstive adjustment so don't give it a 'handful' - tweak and observe. Take the previous above advice and make a note of all your original settings in case you get in trouble and want to go back to square one. I'm not familiar with your model so can't advise further. regards, yt.

    In Service Menu, access buttons under front flap - pressing PROG + / - alters parameters, VOL + / - alters level of selected parameter, on this tv it is a cyclical adjustment so if you go too far you will eventually return to starting point.
    First parameter is R Cut, skip this.
    Second is G Cut, as referred to by red16v above, as stated this is THE likeliest solution. Default setting is 64H, try altering in small steps on a freeze frame containing dark areas.
    Third is B Cut, skip this.
    Fourth is G DRV, you could experiment with this too. Default setting is 30H.
    Fifth is B DRV, skip this.
    Sixth is CNTX, experiment with this too. Default setting is 7FH. Check Teletext display is acceptable if altering CNTX.

    Just to say once more, write down your default settings, they may vary from those above. You can return to defaults if required.
    Providing you ONLY adjust the above, there is little reason to worry.

    Agree with red16v, G Cut is probably all you need to adjust. :cool:
