Re: Monitor went blank
This is a generic symptom that could happen to any LCD
The following is a generic answer applicable to most.
Two possible causes are bad capacitors or a bad light inside
the LCD panel.
Open the unit and check to see if any of the capacitors in the power supply or
other boards look domed or vented on the top.
Replace any capacitors accordingly. Use the same value capacitors. Most often,
1000uF 16V or 25V, 470uF at 16 or 25V, 220uF at 16V or 25V.
If this doesn’t solve the problem, try checking the surface-mount transistors
on the inverter board that run the lights. Some times these transistors go bad.
Check the area for any cracked or overheated ceramic or mylar capacitors.
Also, you may have a bad light inside the panel. This is
tough to test without a spare light to use for troubleshooting.
You can take the panel apart and inspect the lamps but it is very tedious. It's
tough enough to get them apart and back together again never mind keeping the
layers clean. You have to try not to get any dust between the layers or you
will see it in the picture.
There are usually two light fixtures each of which holds two lamps. One fixture
is at the top and one at the bottom. Remove them one at a time and inspect the
lamps to see if any are broken or very dark on the ends. If one looks out of
place, it could be bad.
You'll have to find replacement lights on the net. It's not easy to replace
them, but if you've gone this far, good luck. You should be able to get generic
instructions off of the site that sells the lamps.

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.
If tried the monitor on two other computers with the same result -- definitly your monitor is faulty. Take it to the repair shop. To make double sure, run your computer with another monitor. If everything is fine now; you can blame the monitor.
