Troubleshooting
Check
•Projector power cord is not plugged into the wall outlet.
•Selected input is wrong. (See page 24.)
•Cables incorrectly connected to back panel of the projector. (See pages 12–15.)
•“Contrast” and “Bright” adjustments are set to minimum position. (See page 43.)
•Picture adjustments are not correct. (See page 43.)
•Adjust the focus. (See page 16.)
•Projection distance is too long or too short to allow for proper focus. (See pages 21 and 22.)
•OSD Display is set to “OFF”, preventing to display some or all On-screen Displays. (See
page 36.)
•If the picture is normal, the sound is due to cabinet shrinkage caused by temperature
changes. This will not affect operation or performance of the projector.
•Refer to “Lamp/Maintenance Indicators” on page 44.
•Adjust the “Phase” setting. (See page 33.)
•Change the input signal type. (See page 36.)

(RS-232C) Specifications and Command Settings
PC control
A computer can be used to control the projector by connecting an RS-232C cable (null modem, cross type,
commercially available) to the projector. (See page 14 for connection.)
Communication conditions
Set the serial port settings of the computer to match those of the table on the next page.
Signal format: Conforms to RS-232C standard.
Baud rate: 9,600 bps
Data length: 8 bits
Parity bit: NON
Stop bit: 1 bit
Flow control: None
Basic format
Commands from the computer are sent in the following order: command, parameter, and return code. After the
projector processes the command from the computer, it sends a response code to the computer.
Return code (0DH)
C1    C2    C3   C4    P1    P2    P3    P4
Response code format

Command format
When more than one code is being sent, send each command only after the OK response code for the previous
command from the projector is verified.
•When using the computer control function of the projector, the projector operating status cannot be read to the computer.
Therefore, confirm the status by transmitting the display commands for each adjustment menu and checking the status with
the On-screen Display.

This SHARP projector uses a DMD chip. This very sophisticated chip
contains 480,000 pixels. As with any high technology electronic
equipment such as large screen TVs, video systems and video
cameras, there are certain acceptable tolerances that the equipment
must conform to.This unit has some inactive pixels within acceptable tolerances which
may result in inactive dots on the picture screen. This will not affect
the picture quality or the life expectancy of the unit. If you have any
questions about this matter, please call toll free 1-877-DTV-SHARP
(1-877-388-7427).

Appendix
Glossary
Aspect ratioWidth and height ratio of an image. The normal aspect ratio of a computer and video image is 4 : 3. There are also wide images with an aspect ratio of 16 : 9
and 21 : 9.
Auto SyncOptimizes projected computer images by automatically adjusting certain characteristics.
BackgroundInitial setting image projected when no signal is being input.
ClockClock adjustment is used to adjust vertical noise when clock level is incorrect.
CLR Temp (Color temperature)Function that can be used to adjust the color temperature to suit the type of image input to the projector. Decrease the color temperature to create warmer,
reddish images for natural flesh tones, or increase to create cooler, bluish images for a brighter picture.
Composite syncSignal combining horizontal and vertical sync pulses.
Digital keystone correctionFunction to digitally correct a distorted image when the projector is set up at an angle, smoothes out jaggies on keystone images and compresses the image
not only horizontally but vertically keeping the 4 : 3 aspect ratio.
Digital shiftShifts image up or down easily by / buttons when RESIZE mode of input image is NORMAL, BORDER, or STRETCH of COMPUTER, VIDEO and DTV
inputs.
DVI (Digital Visual Interface)Display digital interface that also supports Analog interfaces.
GAMMAImage quality enhancement function that offers a richer image by brightening the darker portions of the image without altering the brightness of the brighter
portions. You can select from four different modes: Standard, Black Detail, White Detail and Brighten.
HDCPDigital entertainment content is protected from copying with the HDCP system.
Intelligent compression and expansionHigh quality resizing of lower and higher resolution images to fit the projector’s native resolution.
PhasePhase shift is a timing shift between isomorphic signals with the same resolution. When phase level is incorrect, the projected image typically displays horizontal
flicker.
RESIZEAllows you to modify or customize the picture display mode to enhance the input image. You can select from four different modes: NORMAL, FULL, BORDER
and STRETCH.
RS-232CFunction to control the projector from the computer by using the RS-232C ports on the projector and computer.
StretchMode that stretches the 4:3 image horizontally to display it on the wide screen.
Sync on greenVideo signal mode of a computer which overlaps horizontal and vertical sync signal to green color signal pin.
