The colours on screen have changed with blue and green being the dominant colours now. There seems to be a lack of red ie, all people are now light blue. There seems to be a halo effect around the outside edge of the screen. I have tried reconnecting scart and changing setting on the TV but no joy. I'm now worrying that it's something more terminal!
The picture on my tv is mainly blue and green for about 2 weeks. I just turned on my tv and it was like this. I have reset the picture settings and taken out the scart cable but the colour on the screen is not changing. Can anyone help with this please?

It sounds like your TV may need degausing.
Is your TV situated near to any loudspeakers or other devices with large magnets inside them? Or has anyone been near your TV screen with a magnet???
You need to try to get the screen demagnetised (degaussed). Many TV engineers have a degausing coil that could do this. It only takes around 20 seconds at most.
Some TV's like Mitsubishi have a DG button on the remote, that does this function without the need to call out an engineer! It only needs one press of the button every few years!
ok well "tube" tellys as they are called use an electro magnet to keep the picture stable and colours correct its called gaussing now if you have a speaker or something magnetic nearby it will stuff up the colors but only normally producing colors like purple,green, or white
if you have colors across the screen (that aren't caused by magnetic force) then you need to take it to a repairer or decide wether or not to buy a new one this issue can turn out to be quite hard to fix and can be expensive the different colored electron guns may be burning or burnt out causing pale color or it could be as simple as a power transistor in the H.V supply has shorted out..and causing power issues to the tube.
hope this helps,ben
Did you change the resistor by yourself? I am not sure if your TV has manual adjust on the back of the TV that you can adjust. Some times turning the TV Off and unplug it from the wall helps because it resets the TV. Check your Back ground color and see what is the dominating color. Blue, Green or Red. If this doesn't work please call a professional to look at it.
