I am working on an HP pavilion notebook.
It has windows xp home with svpk3.
It is one of those hp's that had the problem with the hinges and when you would opened it, it was stiff and broken the bezel.
Well because of that the user has actually broken one of the hinges and also removed the bottom park of the bezel so that the inverter is exposed.

Here is what happens.

When you turn on the pc, you can hear the HDD spin. There are no beeps or flashing lights.
I looks like it is on, but there is no video. You can leave it in this state for about 8 hours, and then the screen comes on.
Have tried it with external also, no go.

Any suggestions

Can you give a little more background to the above statement please?

You can actually see the "Windows" Screen or the "HP Logo" screen?

when the screen appears dead, shine a strong flashlight at it and see if you can see a faint image. That would indicate a backligh/inverter issue. Several HP laptops have the inverter near the hinge assembly. Sometimes replacing the inverter can fix it, but not always.

google the model number and disassemble and you might find a teardown view.

I have had several Dells that the inverter failed on and it would come on at irregular times.
