I would look at the ram chips first. A bad one will keep it from booting and they are the most likely suspect. They are common 4164s ram chips, so there are easier to find as well. Also, try re-seating all of the socketed ICs as the pins and sockets can oxidize over time and cause poor connectivity. My old 400 wouldn't boot when I pulled it from storage after ten years. I rocked the ram chips in their sockets and up she came.
