Water damage on LCD Screen

Sony Vaio PGC-GRV680

Specs: Win Xp, 2.6Ghz/512

I have a notebook with water damage to the LCD screen. When I power it up, I can see transparent spots covering some of it's surface. I'm not too worried about these spots though because they are just discolorations and I heard that they will get better with time. What I'm worried about is that there is now a black parallel line going from top to bottom and its about 1.5in thick. There are also some 1 pixel thick vertical lines going from top to bottom that have different colors. Also, a few days ago it was showing everything in green but then started displaying the colors properly on its own. It also started displaying the thick black vertical line just a couple of hours ago. So to repair the problems with these vertical lines and color problems, would the best approach be to replace the video cable? Can it be something else? Please advise.

Sounds like dead pixels and so you need to replace the screen!

But how could all those pixels die at the same time? Why wouldn't it be a problem with the connection or cable?

if it's water damaged, it could still be wet somewhere and intermittently shorting out. Have you physically removed the panel and left everything to dry thoroughly?

Pixels are driven by only a few components that are reused to drive the entire screen.

You should send this to a Sony repair center to avoid failure that might lead to a fire.

I read it wrong and answer it wrong too. So get off my case you goober.

If a pixel is clear it's either because circuits are damaged or connections to those circuits are damaged or loose and no longer work - they're dead pixels. The LCD pixels do not produce light - they just modify the light from the backlight behind them.
Your wide black and other lines are also indications that either the circuits are damaged or connections to them are damaged or loose.
There's a possibilty the wiring to the display from the base of the computer is damaged or loose, often where it goes through the hinge, but that's unlikely. If it isn't the wiring that is the problem, there is nothing that will improve your situation - drivers have nothing to do with these problems.
You probably need to replace the whole display unit with a refurbished or new one.
If this computer has a VGA port that you can plug an external monitor into and such a monitor works fine, there is nothing wrong with your video hardware.

The way I see it is if the pixels were really dead I would be seeing irregularly shaped groups of black/dead pixels around parts of the screen where the water splashed. But this is a perfectly vertical straight line. Doesn't the cable transmit signals to the video card from the LCD in vertical lines? I think I can take a shot and see what happens if the cable is replaced.

I didn't open it up yet and let it dry out. My GF spilled water on it and it was 3 days until she gave it to me, and the black line happened 4 days after the accident, but by then I think the panel would have already dried.

This is probably no use to you, but my brothers laptop, has vertical lines on the screen reaching from top to bottom. They were caused by physical damage and was told his HP laptop would need a new LCD screen costing him £400 with service and VAT.
Although he has had water damage to it, which caused small blotches of dis-colouration, which disappeared after a while..
