Digital Projection Highlite 4000dsx User Manual

							Before removing the lamphousing, switch off the lamp and allow the cooling fans to
run for three minutes. When the projector is in standby mode (power indicator
glows amber) disconnect from the mains supply and wait at least 10 minutes for the
projector to cool down. If the lamp has exceeded 1600 hours and the message “LP”
is displayed on the 7 segment display, it will be necessary to reset the projectors
internal running time by pressing the Help key or Power Off key on the remote con-
trol for 10 seconds, then turn on the mains switch.
1. Remove the two screws from the lamp housing cover at the rear of the projector. 
Remove the cover, locate the Timer PCB at top right of lamp housing and dis-
connect connector POXP.
2. Unscrew the two captive screws at the bottom left and right hand corners of the 
lamp housing and gently pull the lamp out of the projector using the handle on 
the lamp housing.
The lamp housing must be handled with care. If it is dropped from just 10cm the
lamp will be defective.
To install a new lamp simply reverse the above procedure.
New lamps are supplied with a fine mesh filter. This filter needs to be fitted under
the filter lid at the front of the projector to the right of the input terminals.

							1. Unplug the projector before cleaning.
2. Clean the cabinet periodically with a damp cloth. If heavily soiled, use a mild 
detergent. Never use strong detergents or solvents such as alcohol or thinner.
3. Use a blower or lens paper to clean the lens, and be careful not to scratch or 
mark the lens.

SOLUTION
Replace the lamp and the
timer printed circuit board.
Hold down the POWER
OFF key on the remote
control for ten seconds to
reset the running time,
then power on the projec-
tor.
Replace the lamp and the
timer printed circuit board.
Power on the projector.
Check all connections, air
ducts and power supply
output terminals. If all
appears in order, replace
the power supply unit.
Check all the air ducts. If
all appears in order,
replace the thermal sensor
on the light engine. ERROR MESSAGE

							Aspect Ratio
This is the ratio of picture width to picture height (the standard television aspect
ratio is 4x3).
Black body
An ideal body or surface that completely absorbs all light falling upon it with no
reflection.
Brightness
The light intensity of the displayed image.
Colour Temperature
The Colour Temperature is the position along the black body curve of the
chromaticity diagram - but takes into account the preset values for colour balance in
the service set-up to take up the variations in the prism.
Composite Signal
A signal line that carries information relating to the entire signal, also incorporating
sync pulses.
Contrast
The difference between the dark and light areas of the screen.
DMD™
A Digital Micromirror Device™ is a true digital light modulator. See D—2,
DMD™ Usage and Operation for further explanation.
Field
A space on a menu screen for data to be entered.
Horizontal Scan Rate
This is the rate at which the DMD™ is scanning the horizontal lines on the screen.
The rate is set by the horizontal sync from the source and measured in Hertz.

							Hs + Vs
This stands for Horizontal and Vertical sync.
Hue
The graduation (red/green balance) of colour (applicable to NTSC).
Hz - Hertz
Hertz is a measurement of frequency, where one hertz is one cycle per second.
Interlacing
An interlaced image is displayed by alternatively updating two fields of horizontal
display lines to produce a constant image. Field 1 (the odd lines) is updated, then
field 2 (the even lines) is updated.
LED
A Light Emitting Diode is an electronic component that emits light.
Lumen
The measurement of luminous flux.
Luminance
Also known as Y this is the part of an S-Video signal which affects the brightness,
i.e. the black and white part.
Noise
Electrical interference displayed on the screen.
NTSC- National Television Standards Committee
The United States standard for television - 525 lines of resolution transmitted at 60

							Resolution
This is expressed as the number of horizontal pixels by the number of vertical lines,
e.g. 680 x 400 means 400 lines with 680 pixels per line.
