The message belowe is a message I copied from an email I sent to a friend.
The mac is a Macintosh LC 475, internal hard drive, floppy drive, keyboard
and mouse with a Apple Colour Plus 14" Display.

I got the monitor for that LC475 (Apple Colour
Plus 14" Display). I plugged it in and turned it on. It turns on. But When I
start the system I hear the monitor flickle and start then it's just black.
I adjusted the displays and made sure it's in the computer correct and it
IS. I read the troubleshooting guide and it just won't work.

I don't think it's the Monitor, as when I turn it off the screen flicks and
goes off (I can see it turn off).

But then again it may be the monitor, the list of monitors that work with
that computer are given and that one isn't on there at all. There is a
compatable Apple Colour 14" Display but this is a Plus.

Do you think it's that the monitor doesn't work with that system? Is it the
actual monitor (The system works with it, but the monitors defected). Or is
it the System itself?

I made sure the keyboard and mouse are connected properly and all the RAM
chips and ROM chips didn't get knocked out of place (because the ride in the
car was bumpy)
