In my experience with 3 Aeros, this is a sign that the solder joints on
the screen connector [on the mother board] have broken. If you have a
very fine soldering tip and are a very good solderer, you can remove the
motherboard and resolder these connections. This will resolve the
problem.

It may also be a cable, but on all of my Aeros, resoldering fixed this
problem.

Subject: reattaching the screen cable properly

I had my clutch break on me, and then when replacing the clutch, my screen
cable became detached from its socket near the keyboard. I reattached it
with success, but later I began to have connection problems (the screen
would get lines and static in it).

In attempting to improve the connection, I ended up tearing the cable,
which I am now replacing.

I have learned that I was reattaching the cable in the wrong way.

I am not sure if the proper way is noted in the clutch and screen
connection sections of the aero faq, but it might be good to add this note
in a prominent place in relevant sections because I did not notice
warnings about reattaching the screen cable when I read the faq.

The proper way to reattach the screen cable is (I think):

After removing the plastic cover that sits around the keyboard, unscrew
the keyboard so it can moved out of the way in order for you to have
easier access to the socket.

Then, there is a little grey plastic piece with a slit in it sitting over
the socket. Take this off the socket and slide the cable through the slit. 
Then stick the cable in the socket and slide the grey plastic piece down
until it snaps in place. The cable should be snugly attached to the socket
now. 

The grey plastic piece is essentially a little wedge which presses the
contacts on the cable close to the contacts on the socket, and also holds
the socket in place.

Mike,

The connector is actually a slide/friction thing.  It's possible to put it
together and have it ALMOST right.

Next time you have it apart, look closely at the two little tabs on either
side of the plastic.  Use those to pull half the connector away from the
circuit board.  BE CAREFUL - it only moves about 1mm.

Then slide the cable in.  When the cable is all the way down, push those
two little tabs toward the circuit board and you should be able to see that
the cable is now crimped, sort of, and shouldn't slide away.

FWIW, I've had my Aero almost since they came out with it, and have never
had a problem with the connector IF I had put it together right.

That solves my mystery of what to do with the little metal clip. I
thought it was there as some sort of shielding clip to maintain
continuity between hard disk and the chassis. 

I did notice my Aero cable was on the loose side. Next time I have to
take mine apart I'll put the clip back where it is supposed to go.

Denis: I had the same problem, so I took screen casing down and tightened
up the clutch screws and it was better....for about a month and
I've noticed screen casing loosening up again, did you try tightening the
screws?  I've got a feeling it's got something to do with too much flex in
the screen casing affecting connections in LCD, just a guess.

... try pressing firmly on the ramp on the
case just above the F3 and F4 keys. If this causes the display to light, then
the contacts on the cable from the screen to the motherboard are dirty...

[Q] My 2 month-old Aero 4/25 monochrome recently developed a "loose connection"
in the wiring between the screen and the CPU so that the screen blanks out when
the clamshell hinge is opened...and the screen works only after you open it
almost fully and then slowly, carefully bring it back to about 110 degrees. The
backlighting still works. I just get a bright, blank screen. I've called
Compaq's product support here in Canada, and they've told me that the "tape
that holds down the ribbon that goes to the screen probably became unseated
within the hinge," and they would fix it under warranty. Has anyone else had
this problem?

[A] Yes. When I opened the case of Aero that ribbon-like cable slipped off the
hinge. I doubt whether it ever was properly seated. Ask them to replace it with
a longer cable if they have one. The original one is definitely too short.
