Compaq FP7317 monitor is dark. Can see very faint image on the screen. Tested with two computers - isolated to the monitor, the video card is good. Suspect backlight inverter.
1. Is this the most common solution to this problem, or should I be checking something else?
2. If the inverter is bad, can the part even be replaced? If so, where can I get it?
To close this thread, I just wanted to let you know that I decided to replace my monitor. I'm about 99.9% certain that the inverter is bad. After searching numerous sources including HP, I concluded that the required parts are not sold to the public. The inverter is a common failure in LCD monitors, so buying a used monitor for parts wasn't a good idea. Since I had to buy a new monitor, I decided to upgrade to a 20". I'm disappointed that my monitor only lasted 2 1/2 years, but maybe that's the norm these days.
For what it's worth, the inverter board on my IBM Thinkpad went out about 3 years ago after nearly 5 years of service. IBM sold the circuit board for about $30. I replaced it myself and saved my $4,000 (at that time) laptop. I will never again buy a Compaq computer or monitor - too many quality issues with my desktop and laptop (R3000), and HP doesn't sell internal parts to consumers. If something breaks, good luck fixing it. What could be an inexpensive repair, turns into an expensive replacement.
Thanks again for your kind assistance.

Re: Compaq FP 7317
I'm not sure about the inverter part of this but have you checked the menu options on the monitor itself to be sure the brightness and contrast haven't gotten messed up? Sometimes as a monitor gets older it requires more brightness to look the same.

I suspect that when you reattached the monitor back you might have moved the agp card out of her slot. Check if you have connected properly your monitor to the pc
And if the agp is in it's slot properly attached.
Hope it helps, good luck!!
Turn on the computer and complete the following steps:
Step 1: Check cable connections
(If you can see the initial HP or Compaq logo screen but later lose the picture, you can skip to Step 2.)
check the video cable connection on the back of the computer and on the monitor. Make sure that it is connected properly and the connecting screws are tight. Turn the monitor off and then back on again (while the computer is on) to see if an image appears.
Some Flat Panel monitors have two similar power input connections placed side-by-side on the back of the monitor, which sometimes allows them to get confused for one another.
One connector is used to supply power to the speakers with a separate power cord, while the other connector is used for the monitor's power adapter.
Ensure that you have the monitor's power adapter cord plugged into the power connector and not the speaker connector.
After you have reconnected the power cord, turn on the monitor (while the computer is on) to see if an image appears. If there is still no image, continue to the next Step.
Step 2: Resetting the monitor
At first setup, or under certain signal conditions, the monitor may not be able to switch to a new display resolution. Do NOT shut down or restart the computer. Instead, perform the following steps:
Turn off the monitor using the Power button on the front.
If the Power button does not respond, unplug the power cord from the back of monitor and wait five seconds.
Plug the power cord back in.
You should see the image from the computer on the screen.
