No Power on my sony vaio

I have a Sony Vaio with a motherboard, foxconn ml194v-0 e253117. The power adapter is fine and I've tested the lead up the connector on the motherboard and the voltage is correct there; however, there is no power that I can find beyond that point. There are no LEDs or other indicators on when plugged in.

Should I assume a faulty motherboard? Where can I find a replacement?

Thanks
