I have an HP Pavilion dv2000 laptop with Windows Vista Home Premium 32-bit. There is a perfect display all the way through startup until the desktop shows up, then the screen goes black. I did some research on Google and read something about shining a flashlight on the LCD screen. I did this and I could see the desktop, icons and all, dim with the flashlight shining on the screen. However, it did not provide a solution.
I also did some searching on the hp.com forums. One person told me I likely need a new inverter, one person said I likely need a new backlight which would require sending it to a repair-shop because it's so labor-intensive, but the most number of replies I got said it had to do with the onboard video chip overheating. I got some links to YouTube and watched an 18-minute step-by-step video on how to take apart just about everything to get to the video chip. Then, what followed was taking some copper sheeting...aluminum foil, but about as thick as the metal from a soda can and made of copper...putting some thermal paste on the chip and fitting a piece of this copper sheeting directly onto the chip to dissipate heat. They also went through steps to take off the heatsink, one of which covers both the CPU and video chip, and fan and air dusting out the fan for preventative maintenance.
Apparently, this same problem occurs with the HP Pavilion dv2000, dv6000, and dv9000 laptops for anyone that is having this same problem.
I'm not afraid to take apart the laptop, but I am wondering if this is indeed the problem and will end up fixing the monitor display or just helping dissipate heat better for the video chip.
Also, I do get video with an external monitor. No problems whatsoever with an external monitor attached to the VGA port on the left-hand side of the laptop.
Thanks!!

Yeah, I tried booting in safe mode already. Screen still goes black in safe mode. I tried going into BIOS as well, following directions that I needed to change some settings. After about 15 seconds, the screen went black. And the external monitor hooked up doesn't display BIOS, so that option is null.
