Poor monitor image on Micron Trinitron CRT

[Dave Smith]

A friend gave me a monitor that he never could get a decent display
image on. It came with a Micron computer he bought about three years
ago. It's a 19" flat screen Trinitron with the model number "CPD-4401
Trinitron" on the back. I've connected it to two computers, each
running Windows XP Pro, and I also get a very poor image. The image
has poor contrast, a greenish color cast, and no real blacks. It also
has lines across the screen about an inch apart and maybe ten degrees
off horizontal. I posted a photograph (not a screenshot) of the
monitor image at: http://members.cox.net/kprdave/monitor.jpg The
black border is added and is true black. I'm fairly familiar with the
adjustments on my other monitors, and this is the best I can get, even
using the color correction in my video card's software.

In the Device Manager, it's listed simply as "Plug and play monitor."

I can't get any info about the monitor from the Micron website as they
seem not to support any hardware but memory anymore. I didn't have
any luck at the Sony site either. I did find a Win. 95/98 driver and
tried that, but it didn't improve the display so I rolled back the
driver.

Any help would be appreciated. Thank you.

It's a re-badged Sony Trinitron. Go to Sony's website and get their .inf. Also
do a google search on CPD-4401.

Yeah. I did that. All I could find was a Windows 95/98 driver and it
didn't help.

What strikes me as odd is that the former owner accepted this monitor
instead of having Micron replace it.

Regardless, it appears to be a hardware fault within the monitor
itself. With TV sets it could be related to a capacitor failure in
the vertical sync circuit, though I don't know if this applies to
monitors as well.

I seriously doubt that anything other than repairing the monitor's
internal fault can compensate for this and result in a reasonably
useable monitor. You might leave it unplugged for a few days and then
open it, see if there's any obvious sign of problem, but remember that
this is potentially lethal high-voltage, not something you should be
messing with if not already knowledgable in such things.

If I had to guess, a repair shop might want $60 to fix it, though
YMMV, I could be wildly off. If the monitor hadn't been used much in
it's 3-year life due to the problem then it might easily be worth
($60?) to fix it.
