There is usually a water cut off , behind the refrig , mounted on the wall , or , a cut off under the sink , connected to the cold water line ( with a small cut off valve ) .
The hissing noise , is usually associated with a hole or cracked water line . You can also try removing the ware filter , to see if the noise stops .
Would need more info , to have an idea where the water line is defective .
I would first try to locate the source of the hissing. Try spraying some engine starting fluid around the hissing area and home in on the source. The engine revs will change as the starting fluid is drawn into the engine. Sounds though more like a vacuum as you have suggested.
If the hissing noise is from the LCD, it could be from the power supply due to failing capacitors. This noise is generated when the TV is trying to compensate for the lack of voltage/curent requirements.
