My monitor is a Gateway FPD 1730 and it was working nice until few month ago when it just refused to power on. The power led is lightind but I know that it doesn't mean much, and if it is quiet in my office, I can hear a very high frequency sound, but this is all is happening. I just want to know what could be the problem, how can be solved (repaired) and if it worth to be repaired

Re: No Power On at all
What it sounds like is the Power supply on your FPD is bad. If its making a High Pitch Sound, A circuit or piece of your power supply is failing. It would need to be replaced in order to get it working.
You can repair this easily if you have another FPD 1730 lying around that doesnt work you can replace parts, but its best if they were made around the same time because certain models have 3 boards(video board, inverter, power supply) But most have two boards (power supply, video card)
They are easy to replace and maneuver if you want to give it a try. Open the FPD and see what kind you have. If anything you might be able to find a part online.

It can be bad caps in the power supply, bad inverter circuits (check the green color fuse (F1, 4A 125V) close to the heatsink and a trim pot), bad inverter transformers, bad lamps.
You open it up using flat blade screw driver starting along the bottom edge of the case. Post back what you see insdie so we can guide you further.
This sounds like a typical Capacitor in the Power Supply fault. Some people take them apart and replace the capacitors, however I recommend that you get a "Quote" for repair, as these often "Chain Fault" and I have seen a lot of disappointed would be fixers.
nonnie707, It is very possible that your monitor's internal or external (lay on floor) "switch-mode-power-supply" has a problem. Prove that your pc is working by connecting KNOWN GOOD monitor to your pc!!! If you are not electronics technician then you will need to question Gateway as to warranty service or possible swapout for a REFURBISHED unit if your unit is deemed as premature failure. May cost $ for swap. READ my FIXYA profile and that of other FIXYA TECH's (buddymc, budmrtn) for more options as to "what to do"!!! Remember, If very strange and weird things start to happen (occur) with "cold-cathode-fluorescent-lamp" backlit LCD display, the first place I would investigate would be the units "switch-mode-power-supply" Good luck with the repair. 12fixlouie
Its sounds like you have fallen victim to the bad capacitors on these models. You can Google gateway capacitor problems and find a ton in information and unhappy people. I was one of them and had the same symptoms as you. Mine would power up with a blue light then turn orange and not come back on one day then the next it would work untill it finnaly quit all together. I ended up replacing 6 bad ones on my inverter board. This cost me about $5.00 for the parts at Radio Shack and alot of time+beer lol. You can find alot information on this here http://www.badcaps.net/ There are also alot of guys on e-bay that will replace the caps for you if you mail them the board. You can just go to ebay and type monitor power inverter board. This will return a few of these guys.
Check to see if the image is Dimmed. Chances are the power supply on the FPD is either dead or not supplying power to the back lights.
Your problem is the power supply or the inverter on your board, you can replace it and it will be fixed. Easy Fix REALLY EASY FIX (inverter is what supplies power to your backlights. A lot of the times the reason a monitor goes black and the green power button is on, is because the backlights shut off. in most designs of the 1730 the inverter is embedded on the power supply. That is most often the case on this problem. Power supply/Inverter=Replace it and you will have a spanking new looking nice monitor working again. :)
