Before you go and spend a bunch of money on new boards and re-flowing, try this-
Pull your battery out and unplug the power cable.
Hold the power button down for about 20 seconds to discharge any power left in the capacitors.
Plug the power in.
Start the computer.
Select start windows normally. You should see your screen again.
This is known as a hard reset. And is a known fix on HP's web site.
This is a software issue related to a corrupt sleep/hibernation mode.
So, now go into your control panel and power management. change all sleep/hibernation modes to never so you don't have this problem anymore.
Remember that now you will have to shut down the computer before you close the lid. Also, notice that part of the towel trick is a hard reset.
Hope this helps.
P.S
Also, a simple way to test your video card is to connect your laptop to an external monitor. Once connected and turned on hold down the function key(FN) and hit F4(has monitor icon) 2 or 3 times to cycle through external monitor modes. Wait a few minutes and your desktop should appear on the external screen. If not try cycling through the function key again. If this works then it is not your video card hardware that's the problem, it's a software problem.

- Disconnect all peripheral devices and remove all USB devices and media cards. You want to test the computer not the accessories!
- Disconnect the AC power adapter, remove the battery, and then press and hold the power button for at least 15 seconds .
- Reconnect the AC power adapter (but do not connect the battery), Press the Power button, Look for glowing LEDs near caps lock and num lock keys, and Listen for sounds of a disk drive and fan turning.
