Home button does not respond

The home button began to have issues responding to touch several days ago. This quickly worsened over the past two days. I turned it off, took the screws out and tried to blow the area clean with the compressed de-duster designed for computers. After reassembling, i still could not get any effect from the home key; the back and menu buttons light up and work, however. This device is not subject to Samsung USA warranty since it is an international phone. Is this a repair I can perform without technical expertise and unique equipment?
