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.

Hi Don,
it sounds like your monitor's Capacitors have gone bad. This is very common. It is repairable, but the caps have to be removed and new ones resoldered on.

If you have soldering skills, not too tough of a job. If not, a shop will usually charge around $100 or so. You will have to weigh the cost vs a new monitor on this one.

Here is some more info for you on the Capacitor plague, that is quite common on monitors now.

The monitor has blown a capacitor, and if your good with a soldering gun and can locate the cap which will have the top rounded instead of flat, remove it and take it to the electronic store and they will give you a replacement. If the capacitor is bad it won't hold the charge and that's why you only see a second or two on the screen. Make sure you are capable of this kind of work, before you decide to do 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.
