Hp Pavillion dv6000 there is no video on the computer LCD panel or external monitor.

You might consider first booting the laptop with an "on-the-fly" operating system such as Knoppix (http://knoppix.net/get.php) to test if you can get any functionality from the video adapter before going through the hassel of adding it to a network, locating its IP, etc.  Its your call.

The BIOS update you pointed out may very well fix your issue however, after briefly reading it, it seems to pertain to fan control which leads me to believe this is an effort to thwart overheating/cooling issues.  Generally you should get some output from the machines display if the hardware components are OK and it is just overheating after "x" amount of time.  Granted there are circumstances where this may not be the case, that is just based on my experience.

You are not getting ANY video output from the laptop?  Not even the BIOS boot up or any POST messages or anything, windows splash screen?

Tried Knoppix boot cd, no luck.  It was reading the drive as the green light was flashing but then it stopped and I noticed the system seemed to reboot....can't tell as there is no image, but all the lights went off then came on and repeated the process.

I think I am dealing with multiple problems.  I will see if a remote control is possible, but now I am thinking the system isn't booting that far.

Also, from my experience, updating the BIOS does not help.

Thanks for the input.  Leaning towards motherboard failure and not fixing due to the cost.
Cheers!

I have an HP DV-2000.  For the past few weeks the screen would go blank for anywhere from a few seconds to 15 minutes.  Sometimes shutting down the system would bring back the screen.

It has now failed completely, no screen at all.  HOWEVER, the external port works.  I've hooked it up to an external monitor and it is working perfectly.

The Fn F4 key on this machine is a "round robin" control of the external vs internal monitors.  One press gives you external + internal, next press gives you external only, next press gives you internal only.  Any time the internal monitor is enabled there is a faint light (more like a glow) on the screen.  I am assuming that is the back light.

I've read quite a bit of posts in various places on the net indicating that many of the dv-2000's and dv-6000's have a variant of this problem.  Solutions seem to run from re-flowing the solder on the video board to striking the computer with a sharp axe (the latter seems to eliminate any indecision about buying a new computer).

Anyone have any ideas?  I would like to repair this beast if at all possible.

Thanks,
Gary

Close!  I almost chose the axe option.  I can't even get an external monitor to work.  I would love to know where to re-solder as I have  basic electronics experience.  

Since all the components are surface mount you really need to use the hot air technique.  Surface mount repair stations have hot air guns that blow hot enough to melt solder.  To reflow a surface mount board, first cover any plastic parts (connectors, etc) with duct tape.  The very carefully use the hot air gun to heat the solder to just above the melting point.  You must be very careful because at the same time you are heating to reflow the solder, you are heating the ICs.  Too much heat on them an they are toast.  Additonally if you are not careful you can melt all the connections on an IC at the same time and the IC will basically be "floating" on solder.  In that situation it is very easy to move the IC out of position.
