when i turned on my xbox the other day, the picture came on, but it was all in funny bright colours, mainly yellow and green, and very bright. it is quite an old model, the white one with 20gb hd. i am using it through a matrix splitter, although i doubt this is the problem as i have been using it like this for 2 years. also, i have plugged my sons new slim 360 into the cable used for mine, and it works fine. when i use the faulty console with the standard av cable, the colour is fine, although picture quality is terrible on my 40" samsung so i would like to get it repaired. does anyone have any idea what this could be.
