Black Screen/display problem

Hi there.
I'm running windows 7 on a HP pavilion dv5-1095eo. So, onto my problem:
After filling my computer with loads of crap over the last year, the screen started to be completely black after rebooting the system. No startup messages or HP logo nor anything else, just black. But besides that, the startup runs perfectly. However, after closing down the lid/screen and letting the computer go into sleeping mode and then turning the screen up again the picture miraculously comes back again. I ran my computer like this for 2-3 months until I yesterday decided to format my computer and install a new version of windows 7. Suddenly the picture decided to never come back on my laptop screen, and now I have to run it via my TV through HDMI. Or more accurately, twice today, after starting up from sleeping mode the picture has come back on the laptop screen, but this was quite random since I've rebooted it maybe 20-25 times today.
I have installed all the latest drivers for my graphics card and everything else, including BIOS, but the screen doesn't seem to wanna turn on, even though the screen itself seems to be working fine.
Does anyone recognize this problem, and if so, can you help a desperate fool?!
Thank you in advance

Hello krixtoffer and welcome to TSF,

I would like you to take a flashlight and look closely to the laptop's screen. Do you see a faint image of the desktop, or whatever is currently displayed?

Hi. Thanks for the reply. To answer your question: No, when flashing the screen there is nothing showing. Everything is completely turned off.
One interesting development in the last two days is that when I open the screen after sleeping mode the picture is showing for about half a second, and then it goes black again. So my conclusion is that all the components of the screen (hardware) are fine. Possibly, could this be a cable issue, between the monitor and the graphics card? I will buy a grounding wriststrap in a few days and then try to open up the computer to see if any cables seem to be disconnected or troublesome in any other way.

My old laptop used to do exactly what you mentioned it was a Fujitsu-Siemens. and sometimes when i logged onto my desktop the screen would go black and i had to close the lid to bring it back up.

I Never figured out what was the cause of this issue but i just assumed that the screen back light was on its last legs.

That is the first place I would check. LVDS cables can get pinched in the hinge and it is relatively common for the connections to work loose.

If you remove the button panel (thin strip above the keyboard) and/or the keyboard you should be able to access the connection on the motherboard. To access the rest you will have to spllit the display bezel.

If it were a video card/GPU issue, you wouldn't get a picture on the external display or it would have the same issue as the internal.
