A line has appeared at the very top of my sony tv screen. The line is straight and is rainbow colours. It will appear when the tv is on video 1, 2, 3, or 4. What could have caused this line to appear and how can it be fixed please?

the LCD is a very complicating device for all CP. you may check it by disassemble it to it's LCD and connect the ribbon wire/flex of the LCD firmly... but this problem is best to replace it with a new LCD... very complicated device indeed
your convergence IC;s are out, they cost about $40, if you know how to solder, you can do it your self, if not , I would try to find somone that can, service centers charge about 4 or 5 hundred, after you get the new ones, there easy to find on the board in the back of the tv
well what i think happend is that the convergance has been modified and some parts has moved inside the TV.
There's lots of posts in this website about this problem so just search for convergance.
