Troubleshooting Video Flow/ - 20
Video Flow
Video signals begin on the logic board at connector J16 and travel
to connector J8 on the A/V interconnect board. The video signals
then travel out from connector J6 (on the opposite side of the A/V
interconnect board) and continue on via the internal RGB cable to
P301 on the analog/video board. From there, the signals are
transmitted to the CRT where they are displayed on the screen.
