Monitor screen goes black but computer still going fine

[Lani]

I have had this problem for about 3 weeks. I am on the PC and my
monitor goes black.
For about a month the monitor would flicker for maybe once every 2-3
hours. Then the black out started. I have changed the video card and
changed to another PC. I changed from the surge protector to an
outlet. I still get the same thing. When it happens, the CPU is
still going fine but no signal to the monitor. I then have to shut
down with the CONTRL, ESC, up arrow, etc. I turn it back on and it's
fine again. This may happen once a day or twice a weekend. I am on
my PC a lot. What do you think? It is a CRT.

I'm pretty sure that monitor was never sold with any of the
(small number of) "PCs" [workstations, really] sold by Silicon Graphics
(SGI). I would thus think it fairly likely that comp.sys.sgi.hardware
is not an appropriate newsgroup for this question.

Sounds like you have a fault in your CRT.

Probably not the CRT itself, but a fault with the monitor. Don't overlook
the obvious either, I've seen this happen when the monitor's power cord
wasn't fully plugged into it.

My CTX 2085 has done this since I bought it in 1995. It goes black for a
1/2 second then sarts up again..................two times a week or so.

Seems like stuff with more blacks in them (darks on the screen) will get
it going.....................seems to be less common now than when it
was new.

my roomy back then thought is was a weak signal which would trigger the
failure of the video for that second.

I use BNC connectors. this monitor cost over 1200 bucks when i bought it
too.
