I see things like it (sometimes in color), oftentimes just as soon as a
monitor starts up, just before you see the picture the computer is
supposed to be sending, usually at startup. Even when the resolution was
the right 1.
It seems to be more a function of the video card/built-in video than the
monitor. I had an ixMicro card that would often flash something like a
grating pattern at startup, & an ATI Mach64 card that would get horizontal
lines forming progressively over the raster, even after the Happy Mac
appeared, when used with a 2ary monitor on my beige G3, until some driver
or something loaded, & everything was fine (usually). (This is a known
problem with some ATI cards used with a G3. Eventually I got tired of
that, even tho' it was harmless, & sold it.)
Anyway, to answer your question about a PRAM battery, I've never heard of
a monitor that had one. Sometimes the more high-end 1s have a flash EPROM,
or non-volitile RAM.
If the raster is apparent, even if only "black," then the guns are firing.
The only reason I can imagine that there would be no picture with several
different output sources, is that maybe a pin on the connector was bent or
something. Or maybe a cold solder joint on the mainboard, that just
happened to manifest itself then & there, perhaps under presure of an
intense overdriving of the CRT? Apparently the signal is just not there.
