Well the red video is wired to pin 1 of the VGA plug and the ground for
red is pin 6. If one of them is missing, it will look just as you are
seeing. Using a known good video cable would only take a minute to
check. And video cables has been known to go bad. As I have had a few in
my time.

It is hard to say if a docking station would solve your problem. As it
depends on where the red video connection is missing from.

I had a similar problem with this computer I am using now about 6 weeks
ago. I too lost the red video going to the external monitor. It is using
a docking station. And I have six of these M465 and three docking
stations. I was worried it was my external monitor. Popped in another
M465 into the dock and it was just fine. Put this one back in and now
this one is just fine and has been working ever since.

    Well, I'll keep this in mind, Bill. Right now the RED is back again.
It happened after I did a partition backup with an Acronis rescue CD. As
it is using Linux for that backup, I wonder now if perhaps the video
driver in the Linux "cured" the problem temporarily. Of course it could
just be a coincidence as the RED color came back occasionally even
without using Linux.

It is hard to say with any certainty. That is unless you can reproduce
it on command. My problem cured itself just by reseating the docking
connection. Unplugging and reconnecting connections often cures many
problems. Doesn't work for everything though.

Some laptops have a separate board for the VGA socket. Some others are
on the motherboard. If yours is separate, it won't hurt to reseat the
connection to the motherboard.

  Those are the exact symptoms I had with my HP, and it indeed turned
out to be the GPU solder connections.  Once they took the lead out of
the solder, it took certain companies a while to come up with a
formulation that could handle temperature changes without cracking.

  As someone who's done the "home reflow" thing, I can tell you that if
you do it carefully, its low risk to the computer itself, but that, of
course, doesn't mean NO risk.

  Its worked for me each time I've done it, but I go out of my way to
make sure to remove everything possible from the board before I bake it.
  It is a temporary fix, though, as the solder itself is still
defective.  Once my HP failed for the first time, I have to do the home
reflow every 3-4 months.

  But, its better than shelling out the cash for a new laptop...for now!

Not to mention the satisfaction one feels after fixing it himself.
If I venture to that soldering job, I would probably have to get better
soldering tools than what I have from my old Heathkit days. It wouldn't
hurt to view some video of such "home reflow" job, either. Maybe there
is something on Youtube but I haven't checked it yet.

Anyway, thanks for the tips.

  There are several videos.  My suggestion... Stay away from the heat
gun method.  Its too hard to control the actual temperature on the chip.

  The method I used was the Oven Method.
1) Remove the motherboard and all removable piece from the motherboard
(especially the battery!).
2) Preheat your oven to 405 degrees.
3) Take a baking pan, ball up four pieces of aluminum foil, and place
the motherboard on the foil balls so that its level and raised from the pan.
3) Place the pan with MB on it in the oven and bake for 10 minutes.
4) When time is up, turn off the oven, open the oven door, and *let the
motherboard cool to room temperature naturally while still in the oven*.
5) Reinstall the motherboard.

I've done this 3 times to my dv6000 series so far, and no ill-effects
that I've noticed.  As I said, each time I do it, it seems to last about
3-4 months before I start getting the symptoms of cracked solder again.
