Small Rectangle of the Screen

[Jack Gillis]

I posted this over on comp.sys.laptops and meant to cross post hear but let
I get away from me before I realized my mistake. So, please forgive.

My Compaq 2010 US has a small rectangle in the upper left quadrant of the
screen. With power off, it is grey and with the power on it is black. If
you remember punched cards, it is slightly smaller than the rectangular hole
in one of those. It looks a little large for a dead pixel. But what do I
know for this is the first I've seen on a flat screen?

Should I be concerned at this point about more of them appearing? I really
don't want to return it right now under warranty. Later this Fall, if I
need to.

Thank you very much for you thoughts and advice.

Maybe someone who knows for sure will show up, but it sounds like dead
pixels. Since you see a difference when it is turned off, I would have
to guess it is some kind of defect in the screen.

Have you tried it with an external monitor?

Thank you very much, Clark.

Yes, I just did that (now that you reminded me it was possible to do.)

The little square doesn't appear on the external monitor.

Yes I remember 80-column cards: bad old days!

Pixels are VERY tiny. Your small rectangle of distress contains many
pixels. I don't think they are dead. Sounds more like a failure in the
electronics that drives them or a broken trace in the connection between
the driver output and the screen itself.

Take advantage of your warranty.

Thank you very much, Roby.

I will probably send the thing back late in September or early October.

I feel like a complete ninny.

The shape started changing a little bit so looked at it under a big
magnifying glass and found it was a small pile of trash of some sort. A
damp cloth cured the problem. So much for high tech reasoning!

Thanks to all who replied.
