I have a Dell cpx laptop that the screen sometimes starts to flicker.
Sometimes it goes almost totally blank. I have noticed that if I
squeeze the right side, around the vertical center of the screen edge,
that the flickering will stop as long as I hold some pressure on it.
Does this lead you to believe it is a poor connection of some sort or
a failing part? Is my best bet just to replace the whole lid assembly
and all? Is this where the lcd inverter is located?
Any help is appreciated.

Thanks
David

I have an old Toshiba laptop (ca 1998) that would lose its screen
illumination just as you're describing. I would pinch or snap my finger on
the upper right side of the LCD to get it to work. Finally, about a year and
a half ago, this method didn't work. Thinking the machine was now a boat
anchor I was able to move all my data off it because the screen was *just
barely* readable if I worked at night in a darkened room with a blanket over
my head! After I got settled on a new computer I took off the screen bezel
and found an inverter board about 3/4-inch wide by 3 inches high. It
generates high voltage power for the backlighting somehow. I ordered a new
one from impactcomputers.com for about $35 and got the machine working
again. Now I use the machine to take on trips to download my digital cameras
to.

This response is the comp.sys.laptop entry in the most useless response
cataegory of the 2008 newsnet awards.

But I should point out that there is some stiff competition this year ;-)

The symptoms you describe are classic of a loose connection. If you can get
the screen assembly apart, you may hit lucky and find the culprit. My first
guess would be a poor connection to the actual backlight tube itself, but
there is no guarantee that the bit you pinch is that close to the actual
fault.
