CIRCUIT DeSCRIPTIONS
MAIN lvDS ChECk
To confirm that the Main board is outputting Picture Content signals, check P902 (LVDS)
for output. Check pins 11-20. This signals vary, but looking for signals like the ones shown
below on any of these pins will confirm the output of video content. This signal is using
a standard SMTE Color Bar output from a generator as the input source. Remember
there are actually 10 pins with LVDS signals. This only represents two waveforms as an
example.
