I am pretty sure that my monitor has the same problem as others mentioned here (starts for a few seconds, then goes black). I did the "flashlight test" (thank you for that) and can see my desktop. Do you know of anyplace on the web that explains how to replace the FPD1760 inverter board with step-by-step directions? This monitor is just out of warranty and I decided to give replacing the inverter board a shot before I give up on it.

Re: Replacing Inverter Board
I did some poking around and only found a few places that sold inverter boards for this monitor. Ebay has one that sells for about $80:
I wasn't able to find any specific instructions posted, however, taking a typical LCD panel apart and replacing the board shouldn't be too difficult. The only hard part is not getting shocked, which is why this is not a job for the typical user. Anyway to disassemble the typical LCD you remove the pedestal from the back of the LCD then remove the screws around the back of the LCD, remove the back and look for the inverter board. Typically it is covered with a metal shield; again the hard part is knowing how to correctly handle the parts.
Considering you can buy a new 17" LCD for $120 to $150 (and has a 1 year warranty) you might want to consider investing in a new monitor instead. If you have any other questions let us know, otherwise please don?t forget to rate this posting.

Hope this helps.... Your monitor has an inverter issue. You know it's an inverter problem when:
1. Your monitor starts normally and displays the startup/desktop screen for a while.
2. Then it suddenly goes off, leaving a blank (black) screen or a very dim display.
may be this is you are mentioning there is no display in your monitor or u have already getting the boot display. if u getting the boot display it must be the problem of your monitor inverter board in side ur lcd. otherwise it must have your computer memory not working properly so u must clean and re install your memory first.thank you.
The problem is in the power supply inverter board, caused by bad capacitors. To have it repaired by a professional will be costly and consideration should be given replacing the monitor, "average life span 3 to 5 years" in most cases.
That is often an inverter failure. Try turning off the room light, and point a flashlight sticking to the dark screen. If you can see a very faint picture, then the inverter has failed. Before replacing the inverter, the PSU must also be tested. If the PSU does not supply power to inverter, then the PSU and not the inverter is the part to be tested.
If the screen is not dark, but there is backlight and no picture, then the problem is not the inverter. In that case check the source and the connection cable. If the cable is OK, then it is usually the main controller board inside the monitor. Once again the part must be tested.
If the computer starting up and Windows is running properly but the screen is black (or the desktop is barely visible if you look at the screen closely), the backlight inverter circuit is probably to blame. This provides power for the display's backlight, and without the light you can't see the display even though it is working properly.
Fortunately, replacing the inverter in most laptops is pretty easy. Replacement parts and how-to information for many brands and models can be found online. Just search for "replacement inverter" for your brand and model and you should find several sources. A good place to find vendors today is eBay.
Replacing the inverter typically involves only a few steps. You remove a few screws to open the display. The inverter is usually a small board at the bottom of the display, held in by a couple of screws. Unplug a couple of cables, take out the old board. Then put the new one, reassemble the display and you should be back in business.
On the other hand, if the power light comes on when you press the button but the computer isn't starting up to Windows, there's some other issue that needs to be fixed. Connect an external monitor to your computer to verify it's really starting up (unless you are hearing the normal startup sound through the speakers). If an external monitor shows everything else is good, replace the inverter. Otherwise you'll need to see why your computer isn't starting.
Good luck on a speedy repair. Thanks for using Fixya!
Hi , The monitor flicker problem. The monitor when turn on will display image for couple of second then turn black. The monitor status led is still green. This will happen each time it is turn on. The symptom at appear to come from the inverter board.
You are experiencing an inverter board failure. You will need to replace or repair the inverter. The inverter drives the CCFL lamps that illuminate the screen if the lamps draw to much current or components on the board are overheating it will shut down the backlights. Some monitors have cold solder joints on the toroidal coils of the inverter that causes this problem, very typical with HP monitors, If you are handy with a solder iron you may try just re-soldering board and replacing push-pull transistors for a few more years of use. Provide make and model and I can be more specific about probable cause and solution.
I agree from what you have described it might be the inverter board, however, I wouldn't start tearing and replacing based on your description just yet. With the computer on and the monitor power LED green shine a flashlight in the lower left hand corner of your screen. Look for the Windows ?Start? button, if your backlight and/or the inverter board is not working you?ll see a faint ?start? button if you look closely. If that is the case I wouldn't recommend randomly re-soldering or replacing parts on the inverter board. Unless you physically see damage or have the ability to trouble shoot the failure to a discrete component I would suggest replacing the entire board if it is economically worth it. Depending on the monitor this is usually an economically repairable problem.
