Check the basic signal flow. The signal flow from
CVIC_IC to the panel output is the same for the
component and video signals. Therefore the lines
after CVIC are not checked. (The 480i and 580i
component signals are not included.)
The signal flows through the same circuits as the
DTV RGB signal does. Check the SOG (Sync On
Green) circuit and the color adjustment circuit. (The
480i and 580i component signals are not included.)
The video signal flows through a different route from
the RGB input signal, and goes into CVIC_IC.
Therefore check the video signal ICs.
Check the D-SUB input.
NO
Checking the PC PWB
Is the user menu properly
displayed?
Check the on-screen
display.
Check the DTV RGB
input.
Check the VIDEO input.
Check the DTV
