I try to open hp dv2-1030us screen but couldnt

set you resoultion to a different setting

I would suggest rebooting your iphone.

Hold the power button (top right) do NOT release.

Now hold and (do not release). the home button (the center round button bottom of phone).

Hold both until screen goes blank... Wait for phone to reboot..and try again.

This is caused by the LCD panel shifting in it's mounts. You will need to disassemble the frame holding the LCD screen in place and re-center it.
The lines will take some time to go away as the set warms up, but be patient, they usually disappear over time.

When you open front door down, cartridges will center in front. Take a hold of top and bottom of cartridge and snap top towards you. It will release and come out.
Putting new one in, put bottom of cartridge in then snap top in.

Power down.  Now power back up and press the eject button at the top of the keyboard and hold until disc ejects.  If that don't work, then you gonna have to open this thing up and physically take the disc out cause something is blocking it from ejecting.

If it just keeps asking you to calibrate, then that means the touch screen is faulty.

when you take all the screws out slide the back down. there is a screw at the bottom holding it from slideing the 9th screw so to speak. you have to take out the u shaped pin on the rod once that u shaped pin is out thats where you will find all the screws to the bracket holding the moter in place take all those out too. it seems like alot but it is really not.

this seems like a hardware problem, most likely you have to send the ipod in for repairs.

you can try another reset and even attempt a restore from this page

sounds like a backlight or display power problem.

Sounds like convergence issue--replace Stk IC's mounted

on large heat sinks. Check power supply for open fuse device.

Re-check convergence alignment.
