    My personal TV has been condemned as beyond repair due to a faulty tube as
    diagnosed by repair tech. There was a damaged 470 ohm resistor on the board
    fixed to the tube neck which was replaced and he swopped over the guns as
    well.
    I'm not convinced and would like to hear some opinions on the following
    fault.

    All functions work ok but picture has a noticeable greeny/yellow haze on
    black and white films and also the same effect on a dark scene in colour.
    Black is the colour that has the most tinge of yellow/green.
    I can see strong red/green/blue images ok if the picture is bright.
    The TV has spent most of it's life on standby or on so never gets degaussed
    very often, I cycled the power switch many times last night and found that
    just before the picture appears the TV shows a full black screen which has
    this greeny/yellow tint, when it switches to picture on a BBC 16:9 signal
    for a second the black bars top and bottom look "normal" as does the
    picture, then the colour haze effect becomes noticeable.
    Does this TV have a fault that sounds repairable and if so can anyone point
    me in the right direction, I can make smoke with the best of them for
    component changes etc but am not a tech. I am used to HV and safe procedures
    so won't kill myself or others! (Sparks by trade but always dabbling!)

    I have looked at the LCD TV's that would replace this and have been amazed
    at the poor digital signal quality, until HD broadcasts are the norm I want
    to stick to my CRT!

    All help gladly accepted.

    I forgot to add my local supplier/repair centre has closed (James TV
    Barnstaple) and Finlux went bust so I have no idea where to go now. Even
    the local independent repair shop has gone now!
