If you're not talking about the portables, I'd check the obvious first. Open
up the case and reseat the video cables. Check for tarnished/corroded
connectors. I haven't opened a Model 4 in years, but as I recall it's
relatively easy to pull and twist the video cables in the process, affecting
the connection.

Maxing out the RAM is probably not a bad idea,
but I'd
suggest you attempt to
figure out why the non-working ones don't work, and, if
that's the only problem
you can't solve, I'll happily send you the necessary DRAMs
for the cost of
postage.
I _think_ there are video problems with both units. They seem to attempt
to
boot up, while leaving the monitor in a relatively
empty state.
