 You can make your own Composite Sync signal with two very simple components. First, run the Horizontal Sync through a 1N4148 diode (very common - can be found at Radio Shack). Second, run the Vertical Sync through a 820 Ohm resistor. Once the two signals have been conditioned this way then you can simply splice them together. You can make your own Composite Sync signal with two very simple components.

 +===== Theory of RGB Operation (SCPH-50000 unit) =====
 +
 +In this model Sony did some major revisioning. They removed the Firewire port, quieted down the fan and DVD drive, and added Progressive Scan DVD playback.
 +
 +Unfortunately, they also comlpletely redid how the video is done. They went to an all digital format which means that you cannot intercept the RGB signals coming from the GS chip like you could do on the 30000 units. All of the digital RGB signals go from the GS chip to a new chip: the CXM-4000. This is a Digital to Analog conversion chip (DAC) which converts all of the digital RGB signals to all of the other video formats.

 +Worse, I could not even find stable sync from this style of motherboard.
