Hello I've got the same computer (HP pavilion DV4000) and... the same problem.

I found the problem is a false-contact in the screen cable (disassembling the computer, you will find the screen cable attached to the monitor).

Just disconnect the cable, and put it again. (In my computer, it must be turned on to solve the problem, otherwise, the malfunction remains.

i recorded this with the laptop apart. throughout this video, when the screen goes black, i was actually physically unplugging and plugging back in lcd connector to the mainboard while its on.....

i can use this computer with an external monitor source. i plug in to the monitor input or use s-video and can still use laptop as normal. so board is still functioning...

Not sure if this is same problem as I had or not, but if it flickers and stops when you move the screen back and forth it may be the screen cable shorting out against the screen mount. See my video "HP G50 Screen Flicker" to see what might be going on inside. I hope this helps everyone with one of these cr*ptops, I mean Laptops...

sorry you are incorrect this this is not a video card issue there is not a video card on this logic board it is all on board.... Also note the hinge issues where the rear bezel cracks. The video issue associated with this unit is from flexing across the motherboard due to the bad hinge design and bad placement of the BGA Southbridge chip

Same computer but the problem isn't so big. When i move the screen it makes like that.

oh... I almost forgot! You must disconnect the screen cable from the mainboard, not the monitor.

You can get the manual for dissasembling that computer from the HP-Online Support Chat (search in their site and explain the technician your problem)
