Diagram will be hard to get, but you should do the visual inpsection of the DC filter caps in the power supply which are very common problems with all LCD monitors.<br />

Does the cord plug directly from the wall into the monitor, or is there a power "brick" adapter between?
If there's a "brick" listen to see if the hissing is coming from the monitor itself or the brick. If the hissing is coming from the brick you may just need a new power adapter.
If there's no brick or the hissing is coming from the monitor, the monitor probably needs repair. With the price of LCD monitors these days compared to the price of labor, you're probably better off getting a new LCD monitor. Just make sure you take your old one to a proper E-Waste facility so it doesn't pollute the environment.
One gets to open it up and find out where the signal from the computer is lay aside. Hunt up the model number on the inside of the monitor (the ODM part numbers) for the service manuals if you can use them. Otherwise you can call Gateway or look for a shop (sometimes even buy repair insurance coverage with the thing in that nonfunctional state.)
