There is a not populated connector in the bottom center of the PCB. What is it? I can see the pins are (from left to right) gnd, signal, signal, gnd, gnd, 4-signals, gnd.
Could it be video? gnd, H, V, gnd, gnd, R, G, B, ?, gnd??????
Above the connector there are resistors missing. The left two signals (that I call H &V) need to be looked at with a scope. If the signals have 60hz and 15k to 32khz then I know what to do. There is a small chance that the IC is out putting standard broadcast video (something like CGA) on those pins.
