Check the capacitors on the power supply if any on the secondary side are bulged replace them all with low ESR substitutes. Panasonic FC work well.
Also check the transistors around the inverter output transformers there are two on each side. Check them with the diode function of your DMM if any measure shorted replace both in the pair. You can find these on e-bay.
That is a power board / inverter assembly getting it would be extremely hard not to mention expensive.

The auto dimming circuit on the ccfl inverter is out. Replace the inverter and it should cure your problem. Seek adult supervision for this repair. Do not try it by yourself.

I have had the same problem and now suspect that cleaning fluid from when I cleaned the screen may have seeped in. After a number of things I did over a period of 2 weeks the problem went away completely.
1. You may be able, if that is your problem, solve it quicker with a hair dryer at a distance (no melt down!)
2. Run HP diagnostics and clean the registry
3. Re- install drivers
Like I said I think 1 is the most likely. I went from every couple of seconds to completely solved.
Another possibility is that an MS update may have caused the problem and then another solved it.

If the power light does not turn color and stay's green on startup, it is not a power problem. It is most likely the inverter. If the unit is in warranty, send it out ASAP. Contact HP customer care by email and have the issue logged in.
If in warranty, they will send you a box by FedX second day and have repaired.
This is a 19" monitor and will not be worth paying for repairs if not in warranty.
