It can be many things that causes the problem. You need to inspect the caps, voltages, solder joints.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Hello Richard Strong,
Welcome, and thank you for using FixYa!
To answer your question: I believe you need to replace the two capacitors that you skipped.
Then touch up every soldier joint on the power supply board. Lastly, I would look for the replacement part for the +5V and -5V transistors on the power supply board. They may need replaced as well. If you have an Ocilliscope you may be able to test out where the power is failing.

Have a great day!

My screen goes black after startup


Try a different monitor, I am sure this sounds overly simplistic to you but, I have seen in my customers have just that, a bad monitor.

If another monitor does the same thing, then you should try another video card. If the video in on the motherboard, there should be a AGP, PCI-e, or an empty PCI slot to put a video card in.

Black screen


Yes, it could be stuck in hybernation


Or.. Check to See if the Lid Switch is Stuck Down... Some laptops have alittle Movable plastic pin that depresses when the lid is closed to turn the screen off... this can sometimes get stuck down to the board button.. causing the symptoms youre experiencing

Monitor going black


HP's are known for bad capacitors in the power supply.
Replacing them is simple if you know how..not so simple if you don't.
Try your local TV repair centre. It should not cost alot to have the capacitors replaced.

Hope it helps =)
