Is the user menu
displayed onscreen?
Check the onscreen
display.
Check the basic signal flow. The
component signals and video signals flow
in the same way from CVIC IC to DAC
OUT. So there is no need to check the
lines after the CVIC IC.
The component input signals flow through
the same circuitry as for the RGB input
signals. Check the SOG (Sync On Green)
circuit and the color correction circuit.
The video input signals flow into the CVIC
IC through a different route from the RGB
input signals. Therefore check the video-
signal DAC and PLL IC.
Check the DVI digital as well as analog
input signals.
Check the RGB input.
Check the component
input signals.
Check the video input
signals.
Check the DVI input
signals.
End.
