               Color Television Wrong Colors

Looking for some help here. 
I have a Sony 26 inch color television that was built in 1985.
The problem I have is that it now generates the wrong colors.
By the way the wrong colors are stable. 
I hooked up the output of a NTSC color bar generator to it and
 this is what I get on the screen;
================================================================
                   Should Be         Is
================================================================
                     white           white
                     yellow          blue
                     cyan            yellow
                     green           brown
                     magenta         cyan
                     red             blue
                     blue            green
                     black           black
=================================================================
I have tried adjusting the Color and Hue controls, they have
an effect but still can not get the colors correct.
 Seems like  most of the color processing is done in a single IC
and the inputs to it appear to be normal, the outputs do not.
Picture tube inputs look correct in that when it is generating
one of the colors the appropriate gun is turned on. If the IC
that does the color was not so expensive ($50) from Sony I would
just replace it if I was sure it was the problem !!
So the question I have, are there any other parts of the chroma
 system that could cause this to happen such as the Comb filter or
Luminance circuits ??

              Thanks in Advance;
