Yes you can replace the lamp. It is called a CCFL lamp.(cold cathode fluorescent lamp). You can get the information and part at www.Digikey.com. When Digikey comes up type CCFL Lamp in the search engine at the top of browser. You can also get the inverter board at the same place. You will have to measure the size of the old lamp. The lamp is on the top of the LCD screen , you may have to take the tape off the top, and split open the screen , to get at it. Be very careful the small wires and socket on the end of tube break easily. The problem might also be at the wire hook up on the tube. It sounds like it could be the inverter, the fluorescent lamp is a miniature unit similar to the larger ones as we know, and brightness is controlled by the inverter. The tubes are inexpensive you could order one and try. Good luck, Bruce.
