Question about HP Pavilion dv9000z Notebook
After 1.5 years of usage bad pixels appeared on the left half of the screen.
But thay are not dead at all, thay just blinking with violet color when they must be blue or a red color when they must display an orrange. Aswell they blink violet on the work space of 3DSMax (grey). This problem appeared in a moment and i could not solve it by reinstalling video drivers or DX.
I've got 2 questions:
1 - what is the matter of the problem
2 - how can I fix it
Plug in an external monitor to your laptop. Is the picture Good on the external, or is it torn like on your LCD?
If it is good on the External, then you need to buy a new LCD and replace yours. If it is bad on there as well, then chances are your video card has gone south. With your model laptop, you will need to replace the motherboard to repair this issue.
In both cases, Ebay may be your friend, as HP is rather over priced on their repair parts.

If the unit is in warranty or your inexperienced with opening notebooks, you should send it in for service.
If you have some experience with repair of notebooks, I would try reconecting the LCD cable to the mainboard first. If that doesnt work, I would go for a new LCD cable. But it might also be defective conectors on either the mainboard or LCD panel.
Be warned tho. The LCD bezel and the bottom screwholes on the LCD assembly break very easily on these models.
If you provide me with the modelnummber I can find the partnumber for a replacement cable. The modelnummber is written on a white lable under the unit. It should look something like this AA111BB#CC.
If a new cable doesnt fix the issue I would recomend you send it in for service anyway. As you dont want to spend to much money on parts troubleshooting.
