HP Monitor MX75 / P1499A dead ('open case, how?)

Before I tear into this beast - suspecting either blown fuse or
softstart circuit failure; how does the case open? Beyond the typical
two screws near the pedestal, there only appears to be some curious
recessed black overgrown-hex screw on the top <!>. 'Thought I would
ask before I start, so as to avoid frustration/pry-bars. It's the
first CRT I've encountered that isn't intuitively obvious from the
exterior...

And, if anyone is familiar with any typical power-up failure
mechanisms (it's dead as a doornail now), I'd be eternally grateful!

Thx, all.

I know this post is years old, and by now you've either figured ou
how to remove the cover, or destroyed your monitor trying..

In case anyone else is looking for the same thing, though, I jus
figured this out on one that came into my shop

Remove the base, and the 2 outer screws in the bottom. The inner one
hold the separate bottom, which is also the circuit board mount. The
don't need to come out

Then, along the top edge where the front and back come together, ther
are two slots about 3 inches in from each edge. These allow access t
a pair of plastic clips that hold the top edge on. Get a wide fla
screwdriver, and slip it into on of these slots. Angle it so th
handle of the screwdriver is pointing toward the back of the monito
as you go in. When it stops, pry like hell.. Kidding. Yo
will need to put quite a bit of force on this though, as it's fairl
inflexible plastic. Firmly pull the handle of the screwdriver towar
the front of the monitor while maintaining the downward pressure.
(This is all assuming your monitor is sitting upright on a fla
surface.) You should be getting to the point of cringing thinkin
you're going to break something when the clip will release with
pretty sharp crack. You'll probably think you have broken somethin
at this point, but it should have just released that side. Do th
same to the other, and the whole cover should slide off the back o
the monitor

If you break some plastic doing this, well :crybaby: it sucks. But
it's a typically annoying name-bran
"don't-fix-it-just-buy-another" monitor. Next time, get a
NEC or Phillips

Laptop repair is fraught with similar fears of snapping plastic, no matter which
brand it is. I've taken apart a client's Dell notebook twice now, and each time
I cringe while I pull the plastics apart. At Dell (and IBM) have service
manuals on their web site for the notebooks, so one can figure out how to take
them apart. HPaq posts no consumer-accessible service info on its web site, at
least nothing I can find. If you are an authorized HP service provider, you get
the service manuals and the right to charge obscenely high prices for repairs.
We here who are not duly authorized HP gurus generally tell people not to buy HP
again, due to the difficulties of servicing and maintenance... Ben Myers.
