Question about HP Pavilion dv4000 Notebook
When my laptop is first turned on, the screen comes on for a few seconds and then goes black. The computer still runs but the screen doesn't show a picture. There is a sleep button on the computer. whenever you press it, the screen comes back on for 1 to 2 seconds then it goes out again. I took my computer to a local repair shop and they tried replacing the inverter and that did not work. They told me the problem was more than likely the LCD screen itself. So now I am looking online for cheap replacement screens. My question is: can I be confident the problem is actually the screen or might it be something with the sleep button/sensor? I want to be sure before I spend money on a new screen.
My hp dv 2000 shut down while working ang the by pressing the power key it resumes to the same position.
this problem repeats every 2-3 minute of working.
Please solve this problem.

Try connecting an external monitor to the laptop, power up the monitor first then boot up the laptop. The video data will switch to the monitor automatically, check if the monitor dislays a normal image and see if the image stays on the monitor.
Also press and hold the Fn key and press the F4 key, these keys toggle the video output between the LCD screen and the video port.
Test to see if this functions correctly.
Get back to me with the results of the tests.

I am sure that power jack is a part of your mother board but you can also replace a new power jack for your mother board. I know that if you send it to HP they will charge you 398$ for repairing the notebook. I will give you a link from where you can purchase a power jack with a nominal price. You can fix it by yourself or you can go to any electronic shop for foxing this. It is as simple as soldering the new power jack on the mother board.
