ARC projection lamp that is replaceable by the customer. This projector is lighter and more compact than
comparable size projection sets using tubes. They will be available in 44 and 55 inch screen sizes. All of
the screen sizes will have a 16x9 aspect ratio. The following table shows the dimensions and weights.
The EM8U is a High Definition Ready set with a screen resolution of 1280x720. It does not have a ATSC
Tuner built in. A Set Top box will be required for viewing ATSC signals.
SET OPERATION
The set has three 1H or NTSC only inputs. They are AV1 and AV2 located on the rear Jack Panel. The
third input is the Side Jack panel. AV3 and AV4 can be either 1H NTSC, 480P, or 1080I signals. These
signals must be in the Y Pb Pr format. AV5 is a DB15 RBG input. AV6 is a DVI 1080I input connector. The
RF input on the Rear Jack panel is for NTSC only. The MON OUT is a monitor output for whichever 1H
Tuner, AV1, AV2, or Side Jack panel signal has been selected.
The indicator LEDs and the Remote Control Receiver are located on the front of the set. When the set is
turned On, the Amber LED will turn On. After the Lamp in the set has switched On, the Green LED will turn
On.
The Control Panel is located at the top of the set. The Power On button is lighted with a blue LED
whenever power is applied to the set.
When the set is turned On via the Keyboard or Remote Control, the set will take approximately 30 seconds
to display a picture. By using the Select button, the Remote can be used to control other devices. A list of
setup codes for other devices is located in the customer's operator's manual. The customer can select the
Menu button on the Remote to make additional selections and adjustments as desired. Use the cursor right
and cursor down buttons on the Remote to select the desired topic.
When Picture is selected, use the cursor down button to select the desired subtopic. For example, press
the cursor down button to select Contrast then use the cursor left and cursor right buttons to change the
values. Additional dots on the lower part of the line indicate that additional selections are present. Continue
to press the cursor down button to make these selections.

MAINTANENCE
Note: The following topics are all taken from the Customer Owner's Manual. They are repeated here as a
convenience and with the assumption that some customers may fail to accomplish these tasks or possibly
may have misplaced their Owner's Manual.
Cleaning or Replacing the Filters
The Cineos TV has two filters that cover air inlets on the bottom of the set. Maintaining a free flow of air
through the inlets is very important. If the air filters become dirty, clogged, or blocked, the temperature in
the set will rise.
Should the heat level become too high due to blockage, a sensor detects this, and a warning message
appears on screen alerting you to check the air inlets for blockage. The message will be displayed for 6
seconds. It reappears every 15 minutes as long as the temperature remains too high.

If the internal temperature of the TV rises to high, a warning message alerts you that the TV is shutting
down. If the temperature remains at this high level for 1 minute, the TV will enter Standby mode. In
Standby mode, the TV is off.
Be sure the TV is not placed on a surface (such as a shag carpet) that will prevent the free flow of air
through the inlets, and periodically clean or replace the filters as detailed in the following instructions.
WARNING: Do not tip the TV when removing or installing the filters. This may result in
instability of the TV.
1. Place your fingers under one of the filter slots located at either bottom left or right in back of the TV
cabinet.
2. Grasp the filter and gently pull it straight out.
3. Examine the filter for dust or other contamination. If it is dirty, clean it with a vacuum cleaner. DO NOT
WASH it. Replace the filter if vacuuming does not sufficiently clean it.
To order replacement filters, call the Philips Customer Care Center at 1-800-531-0039. The part number
for the Philips TV inlet filter assembly is 3135 037 51810.
WARNING:
DO NOT operate the TV without filters. This will cause serious damage to the TV.
4. Turn the filter so that the arrow is pointing toward the center of the TV. Align the edges of the filter with
the slot track, then gently slide it all the way back into the slot. A click sound can be heard as the filter
reaches the correct position.
Replacing the Lamp
The Cineos TV uses a lamp with a limited lifetime to illuminate the picture. A Lifetime counter in the TV
records the operating time of the lamp. One hundred hours before the lamp reaches the end of its life, a
warning message will appear on screen. This will allow you to prepare to replace the lamp or take action
right away. The message will disappear within 6 seconds. It will reappear each time the TV is turned on
until the lamp is replaced.
To order a replacement lamp, call the Philips Customer Care Center at 1-800-531-0039. A Philips
associate will be happy to assist you. The part number for the Philips TV replacement lamp is 3122 438
71310.

8. Slide the lamp door closed.
IMPORTANT: The door must be closed completely to the left. Otherwise, the TV will not operate.

Resetting the Lamp's Lifetime Counter

select the alphabetical code that is provided with the lamp. The recommended Philips replacement Lamp is
rated for 6000 hours, an F rating

control resets the Lifetime Counter to 0 for the new lamp and begins keeping track of the lifetime of the
new lamp.
1. Press the Menu button on the remote control to display the on-screen menu.
2. Press the Cursor Down button to select "Settings."
