LP340/340B/350 Service Manual 8

The LP350

Introducing the LP350, LP340 and

LP340B

The LP350, LP340 and LP340B set a new standard in ultra-light projectors. Weighing less than seven

pounds, yet producing a 1300-lumen image, the three projectors use DLP (digital light processing)

technology from Texas Instruments.

The primary difference between the two LP350 and the

LP340/340B is that the LP350 has a native XGA

resolution (1,064 x 768 pixels), while the LP340/340B

have a native SVGA resolution (800 x 600 pixels). The

LP340B is a lower-cost alternative to the LP340. The

LP340B does not offer digital input like the LP340 and

LP350.

The LP350, LP340 and LP340B are extremely easy to service. The number of boards in the projector has

been reduced to one. Voltage and resistance testing is easy too. You need only to remove the bottom

case to access test points. Nearly all the interior replaceable parts fasten to a magnesium chassis. You

can pull everything out of the case by removing just a few screws.

Below is a table that shows the differences among the projectors.
