With the repair people that is. What you're describing sounds a lot like a crack in the screen, and the liquid crystal is leaking out. While it's certainly not impossible, this sort of thing usually doesn't happen without some kind of abuse.
The kicker is that it could have been a bunch of little things that wouldn't seem like abuse. You might have set some things on top of the laptop, and the weight caused small cracks to form, and then when the crystal was heated up and expanded, it expanded into those cracks, forcing them open wider and wider, until they finally gave way.
It's possible small cracks were there from the time of manufacture, but try and prove that now. Could have been dozens of other possibilities, which are equally difficult to prove.
Since getting a screen replaced on a laptop is generally a significant portion of the cost of a new laptop, this time around, make sure you get a no-fault warranty if one is offered. A warranty where it doesn't matter if you throw the thing out the window, they'll fix it. You can probably flog the current unit on ebay for someone to use as spare parts. Just be sure to format the hard drive a few times using a secure erase program. That way, for the vast majority of people, the data is as good as gone.
The screen on my year-old laptop just had an LCD ink leak (it looks like there was a black ink spill across aportion of my screen and you can see the outline of it even when the computer is turned off). Since this occured, when the computer is turned on vertical and horizontal lines block out most of my screen space.
I realize that I need to get a new screen or a new laptop, but the warranty repair company is telling me that these leaks are generally caused by abuse or misuse, so they won't fix my problem. Trouble is, I've never dropped, abused, or misused my computer. I feel like my chain is being yanked because the company is trying to get out of fixing the problem. Does anyone know what else can cause the LCD to leak? Does anyone else know if Toshiba laptops are prone to any screen defects?
