I changed the LCD cable, screen, but continues to be striped.
Also when I move and fold the screen attached to the lid of the laptop (which has no cover) is made, but when I let go, he turns to see the stripes, which may be?

Your second sentence is not very clear. Can you find the right position for the screen when stripes go away?

I am replacing a display enclosure for a HP dv9000 (dv9620us) laptop. The used part does not have glue to secure some of the retention tabs on the silver material. What is the best type of adhesive to use to secure them? Do I have to worry about any negative effect from using the wrong type of adhesive?

I think you can use just regular clear scotch tape. There shouldn’t be any negative effect.

I have a Dv9000 with a black screen problem i know its not the motherboard because i can still get video on an external monitor and i know its not the inverter because i just replaced it also im not sure if it is a bulb problem because the backlight comes on when i power the laptop if you could plz help me out i would really appreciate it

Let’s see what could be wrong with your laptop.
1. The video still appears on the external monitor. It means that most likely the motherboard still works fine.
2. You’ve tried replacing the inverter. It means it’s not inverter related issue.
3. The screen backlight still works, it means inverter/backlight work properly.

From all above mentioned I can guess that your problem could be with the following:
1. Poor connection between the video cable and motherboard or LCD screen. Try reseating the video cable on both ends.
2. Faulty video cable. Try replacing the cable.
3. Possible LCD screen failure. Cannot confirm without testing the laptop with another working screen.

I put it on an external display and it looks good, had used the EuroCheck and said that the LCD Cable Failed

If external video works properly, most likely there is no problem with the graphics card.
Most likely it’s one of the following:
1. Failed LCD cable.
2. LCD screen problem.

Here’s what you can try if you feel comfortable with taking it apart. Take apart the display panel and try moving the video cable while the laptop is turned on. If moving the video cable affects image on the screen and it get’s better or worse, most likely it’s bad cable.

My Laptop has pink vertical lines on the white parts of the screen, it could be? LCD cable or inverter?

Not the inverter, that’s for sure.
You’ll have to test your laptop with an external monitor. Can you see same lines on the external video?
