Identifying Vestel malfunction - shadows with wrong colors on the screen

[televizora]

The TV is Crown CCT3207W(Vestel 17MB08P-5 chassis)
The problem is with shadows on the screen with wrong colors, that appear usually if there is a high contrasting image on the screen, including gradients. I am attaching a pictures. What do this artifacts mean? Look at the blue shadows, that appear on the parts of the image, where there are gradients of certain colors. Sometimes the shadows are blue, sometimes red - depends of the background color...
The problem is not with the image source. I've tried a STB on the SCART and another STB on the RCA inputs..

If you do not have the skill to replace the Gamma IC on the T-CON Bd, just replace the T-CON Bd.
