Red flashing light on my LCD displa

Specs: Windows Vista
My display has been broken for half a week now.

Symptom: Black pixels are replaced with a pulsating red. Not all black pixels are replaced, but whenever I'm loading Windows on startup the whole display shows flickering red, kind of like red and black static. When Windows loads, only certain areas of black are replaced, and I have reason to believe that it is when the pixel has no assigned color that it is replaced red. It is inconsistent. There are times when I reboot it that it doesnt do this, but then it comes back in the end after an hour being on the computer.

What I have done to troubleshoot: 1) I have reinstalled my graphics driver.

2) I have updated my BIOS. Then uninstalled my display driver, then reinstalled it again.

3)I've tried putting my display on an external monitor. My external display is clear while my main LCD monitor shows all the red stuff still.

I have not reset to factory settings. I have not dropped my computer, but I do have concerns that since it likes to heat up that something might have melted inside. But its been like this for about a year and a half now, and I don't see why it couldn't have melted the first time I stuck into a bag with it still on.

Anyways. Please help. My display is manageable, but it looks infected with something as well. Not sure if its a virus. I've scanned with everything I have (Spybot, Adaware, CCleaner, Symantec)

PS I've recently taken pictures of this whole thing. Here's the blog:

1. Make sure that the cord that goes into the computer is plugged in tight, and check the cord (especially at the end) for any cuts, stretching, etc. Wiggle the cord around in different places while it's flashing red and see if that makes a difference.

2. Try it on a different computer.

If none of these make a difference, I would say that the monitor is on it's way out. I don't know much about LCD monitors, though, so there might be more info that someone else here can give you.

Hope this helps,

It's an HP dv9000 notebook. But as I said, it works great when I do external display. So its probably not the graphics card.

Is there a way to get this fix in a repair shop or should I start looking at new laptops? (That will suck because I spent so much on this one and it only lasted 18 months.)
