m,
I had to sit on this one for a while.
How old is your 2040U?.....Have you gone back to Mitsubishi and checked for
newer files (.icu and .inf) for this old monitor?........I have this
trouble with my old Eizo 21".
Yes, your 2040U could have gone T.U......
If you get the same response in both SVGA and BNC, I'd be looking at the
Video card in the 2040U.
Perhaps a good TV shop can test it. Then, the high-voltage card, and/or
other could be doing this. Specially if this trouble just popped up quickly
for no good reason. Stuff happens. These old tube monitors do have a
"finite" life.............. :(
I can not see the video card being a problem. I use a friendly G200, and
a current R4350 to drive my Eizo. It still plays as best it can w/current
crap off the www.
Lastly, from your description, I just finished doing a similar thing with
my Sister. I loaned here a very old GEM 15in digital FP monitor. She
started getting bars across the screen.........It turned out to be a BAD
Video card. It was an old Canopus GForce256 card I gave her years back.
I realize you have already "isolated" the video cards.........Do these
video cards play well in other platforms?
Best,
Duncan

I have a CRT Mitsubishi 2040u that started flashing this morning when I
turned it on and booted up to XP PRO. I use it as a second monitor to put
my scedule. It does not flash on a DOS screen or at POST. It doesn't flash
on and off. It is like bars across the screen illuminating brighter then
the surroundings that produces a flashing effect. The flashing is continuous.
The first thing I checked was the cable connections. Then I tried a
different computer, the 2040u has a switch that allows you to select SVGA
or BNC. Once it booted into XP it happened from both computers / and
video cards. One a Matrox G450, and the other a ATI 9600 AIW PRO.
But in DOS, black and white screen there is not flashing illumination. It
is probably toast but I thought I would ask. Anybody know what might be
causing this?
