To check the display board video signals

To check the display board video signals
(Note that systems that use the ADLINK M880 motherboard do not have a display board. The
display board is integrated with the M880 motherboard.)
The video signals are checked on the 32-pin connector J2 on the display board A12. You can use
an oscilloscope with a bandwidth of at least 100 MHz to verify the signals. Even-numbered pins
are closest to the PC board. If the signals are not present, suspect the display card. If the signals
are present and the backlights are on, suspect the flat-panel display as the problem. Note that
CLK, A0, A1, A2, and A3 are Low Voltage Differential Signals (LVDS).
