Dell Latitude XT Gets a New Screen and Gets Naked

Posted by admin | 04/11/2008 | 0 Comments

The replacement screen for my Dell Latitude XT arrived today. I was quite hopeful that it would address the gridding issue I’ve been talking about.

I am pleased to report that the new screen is quite the success. I do not see near the amount of grid that I previously saw. It is now only visible when the screen is off or very dim. Even when it is off, it is nowhere near as visible as it was before. Under normal brightness and working under fluorescent lighting, it is practically invisible. On the old screen, under the same conditions, all it took was a slight tilt of my head and I could see it.

Needless to say, I’m very, very pleased. So much so, that any thoughts of returning it have vanished.

This was the technician’s first time working on a Latitude XT and he remarked at well it was built compared to other notebooks he’s worked on. We worked together to figure out how best to take it apart and put it back together.

While the technician was here, I took the liberty of photographing the process. You’ll get to see the XT as never seen before. Click the individual pictures to see higher res shots.

Everything in place	digitizer / lcd cable connected, screen reattached. At this point, I had to leave. But the tech just put all the screws and plates back together in the order they came off
