Apply an XGA 60Hz gray scale input to the PC1 input
circuit and select PC1.
Are the signals of 3Vp-p applied to the signal input pins
(signal names: REV_LVDS, RODD_LVDS, etc.) of
IC9403 and IC9404?
Are pulses (of the video signal) of 3Vp-p applied to Pins
54 to 122 (Except for the GND pin. Check the through
holes, etc. to see whether the waveform appears at the
terminals of IC8005) of IC8003?
Are pulses (of the video signal) of 3Vp-p applied to Pins
200 to 12 (Except for the GND pin. Check the through
holes, etc. to see whether the waveform appears at the
terminals of IC8005) of IC8003?
Are pulses (of the video signal) of 3Vp-p applied to Pins
130 to 185 (Except for the GND pin) of IC8502?
Are pulses (of the video signal) of 3Vp-p applied to Pins
190 to 244 (Except for the GND pin) of IC8502?
Are pulses (of the video signal) of 3Vp-p applied to Pins
21 to 88 (Except for the power supply and the GND pin)
of IC6701?
Is the video signal of 1Vp-p applied to
Pins 124, 133, and 139 of IC6701?
Is the video signal of 1Vp-p applied to
Pins 1, 2, and 3 of the PC connector?
