I have an Advantech PCA-6003 SBC as well as the "motherboard" this plugs into PCA-6108P4-C Rev.:C1. The SBC had two bad caps which I replaced. Everything else appears to be in order but it won't POST, no beeps, no video at all. I tried several different sticks of RAM as well as a known working CPU. No dice.

I don't have any experience with those so I might be overlooking something obvious. I'm using a known working AT power supply to power it.

I played with this last year already and couldn't figure anything out. Maybe 2021 will be better? 😁
