Dear Gurus, Mr. LeKostaj asked: "Does the 2400 have only one lamp? Any chance you can post a disassembly procedure?" Yes. One lamp. Very fragile, needs to be soldered at both ends. Disassembling the screen is fairly straight-forward and you needn't open the computer. Just unscrew the four screws in the case (see diagram in repair manual) and set to. The lamp's under the inverter board, the last thing to be disassembled. Donald McCaig Donald McCaig Yucatec Farm Williamsville, Virginia 24487
