When i see my picture from mainboard, i found two intresting point.
One is the near of right left corner of the main cpu. 9 hole. 2 big, and 7 small soldering point. Is Sata port. i Find a bad motherboard, and change the port, to use sata hdd.
The second is the bottom of the coax rca female connector. is a 3 pin. I think, 2 side is ground, and the center anything. I hope this is component video, but missing some parts. i try this tomorrow.
