1. General Description & Safety Instructions
1.1 General Description
WARNING!
In order to prevent electric shock, do not remove cover.
No user-serviceable parts inside refer servicing to qualified service personnel.
Features
Conventional color TVs apply 50Hz/60Hz alternate scanning and scan a picture in two separate fields,
which results in distinct scanning structural lines and horizontal flicker. As the TVs can display only
25/30 frames of picture per second, it cause wide-range image flicker. The larger the TV screen is, the
more conspicuous the problems are. Therefore, watching this kind of TV, you are susceptible to
eyestrain.
With the world's the state of the art digital inverter technology, our rear projection TV is an improved
product for better performance. With 60Hz progressive scanning, the RPTV can display a whole frame
of picture per scanning and increase display frequency from 25 frames of picture per second to 60. At
the same period of time, the RPTV can scan lines of up to 1250, two times as many as the conventional
TVs. The RPTV removes completely wide range image flicker and horizontal flicker, and offers
sharper and more lifelike pictures.
• Precision vision: With progressive scanning, the RPTV automatically increases vertical
frequency from 50Hz to 60Hz and horizontal frequency from 15625Hz to 31250Hz.
• Automatic white balance correction: The RPTV correct automatically white balance each
power-on, which avoids color distortion due to long time use and delivers consistently vivid
color.
• VGA terminal: You may connect a computer to the VGA terminal on the RPTV and use the
RPTV as a large-screen multimedia display terminal, through which you can surf Internet
and play games.
• Advanced projection tube" High brightness and high-resolution projection tube of the
world's advanced level guarantees high brightness and reliable focus performance.
Other features
• 7" projection tube (3 pieces)
• 470MHz CATV ready
• Multi system/digital NICAM reception
• Theatre and music surround system
• Still picture
• On/off timer
• Wide power voltage range
• Digital frequency synthesized tuner

1.2 Maintenance Instructions
• If a problem occurs (such as no picture or no sound), or if smoke or an abnormal odor starts
to come out from the RPTV, immediately unplug the power cord and contact the service
agency as soon as possible.
• High voltage inside! Non-professionals can not open the back cover.
• Do not expose the RPTV to direct sunshine or put it near heat sources.
• Do not put the RPTV in a place subject to moisture and dust or where the rain can reach.
• Set up a lightning arrester when an outdoor antenna is used. Do not turn on the RPTV in
thunder days. At lightning intervals, pull off the power cord and antenna cable.
• Please turn off power supply of the RPTV while outgoing. In ease of the RPTV is not used
for a long period of time, please pull off the power cord and antenna cable.
• Do not put anything on the RPTV, especially objects filled with water or chemical material
on top of the RPTV. Doing so may cause deformation to the cabinet and screen or water to
spill into the RPTV.
• Install the RPTV in a place with good air circulation. Do not cover the ventilating holes to
prevent the RPTV from overheating.
• Avoid hard objects hitting on .the RPTV (especially screen) or severe vibration when
moving the unit. Doing so may adversely affect location of the inside lens.
• To prevent the RPTV from falling off or tip over, place the RPTV on stable and flat surface
without vibration and fix it according to Operation Manual.
• Do not switch the RPTV on and off frequently. Doing so may shorten life span of the RPTV.
• Do not switch on or off the RPTV by plugging or pulling off the plug.
• When using TV games, computers and similar products with your RPTV, keep the
brightness and contrast functions at low setting. If a fixed pattern is left on the screen for a
long period of time, especially at a high brightness or contrast setting, the image can be
permanently imprinted onto the screen, which is not covered by your warranty.
• Wipe the cabinet regularly using only a soft cleaning cloth.
• If the cabinet is particularly dirty, soak a soft cloth in water to which a small amount of
neutral detergent has been added, and dry it to wipe the cabinet. Do not use organic solvent.
• Keep the screen dry. Wipe the screen using a dry soft cloth. Observe the instructions if using
a synthetic rag.

3. Troubleshooting Charts
3.1 Safety Precaution
WARNING:
Service should not be attempted by anyone unfamiliar with the necessary precaution on the RPTV. The
following are the necessary precaution to be observed before servicing.
1. Cold ground near the point to be tested, not warm ground on the power supply board shall be 0
reference when testing voltage at circuit joints.
2. In the process of servicing, do not turn on/off the set quickly and frequently. The minimum
internal shall be more than 30s.
3. Always be certain that the wires are connected or wrapped as it was after completion of servicing.
4. Keep signal and supply wires from high voltage or high temperature components.
5. Be careful and do not scratch the screen and lens when removing the screen.
6. Normally, do not perform any operation (e.g. press VOLUME UP/DOWN buttons) under the item
of "INIT" of Data menu for final adjustment in order to avoid initiating final-ad-justed data.
Product Safety Notice
Many electrical and mechanical parts in this chassis have special safety-related characteristics.
These characteristics are often passed unnoticed by a visual inspection and the protection afforded by
them cannot necessarily be obtained by using replacement components rated for higher voltage,
wattage, etc. Replacement parts, which have these special safety characteristics are identified in this
manual and its supplements.
Electrical components having such feature are identified by printing on the schematic diagram and the
part list. Before replacing any of these components, read the part list in this manual carefully.
Unauthorized substitutions may result in fire, electric shock or other hazards.
