My daisy has a yellow vertical line pattern, and freezes. Also shows the same on a second monitor. Is there a separate video board? Is a complete motherboard, if required, available?

Is this a good question?

The fact that it does this with an external monitor indicates a failed GPU (Graphics Processing Unit). Sorry to say but it's integrated into the logic board. The 700 MHz is Apple part # 661-2589. You can also use the 800 MHz board in your machine, part # 661-2575.
