Does the blue and red crosses move at all ... eather vertically or horizontally. if they move at all then it may not be the chips.. could be a resistor. if the crosses dont move then it probally the ic. these chips run about 7 to 45 dollars apeace depending on type. at our shop we charge around 125 to put in.

I have not fixed it yet. But I have identified the chip that is causing the problem. If you have a service manual scan it and post it please, so I can show you the chip.
