Additional connection cables are not provided with the TV. They are available at most electronic stores.

CableCARD Technology

CableCARD is a nationwide system standard that allows your local cable TV provider to supply you with an access card customized to your account. This card allows your TV to receive, decode and unscramble the premium digital channels included in your cable TV subscription without the use of a cable box. It also allows your cable provider to automatically update and change your subscription. When you move to a new cable providers area, you simply return the CableCARD to the original cable provider and get a new card from your new cable provider. Please note that CableCARD is a new technology and your local cable provider may not currently be offering this service. As time passes, this system will become broadly supported by most cable providers. The CableCARD system is unidirectional which means your cable provider can send updates to the access card and TV, however, the TV cannot send back signals such as requests for Video-On-Demand or Pay-per-View programs by remote control. Digital cable channels authorized by the CableCARD will be available on the Firewire IEEE 1394 network and can be shared by other products on the network. Some digital channels or programs may not be copied or recorded because of copy restriction limits set by the content owners or copyright holders. The digital television is capable of receiving analog basic, digital basic and digital premium cable television programming by direct connection to a cable system providing such programming. A security card (CableCARD) provided by your cable operator is required to view encrypted digital programming. Certain advanced and interactive digital cable services such as video-on-demand, a cable operators enhanced program guide and dataenhanced television services may require the use of a set-top box. For more information call your local cable operator. Please see page 19 for instructions on how to insert the CableCARD.

Connecting the IR Emitter NetCommand
Figure 17 A quadruple IR Emitter cable is included with the TV.

IR Emitter NetCommand

The emitters connected to these jacks are used by the NetCommand system to control other devices such as VCRs, DVD players, Cable boxes and Satellite receivers. 1. Connect the plug end of the supplied quadruple IR Emitter Cable to one of the IR Output NetCommand jacks on the TV back panel. 2. Run the cable for each of the emitter ends under, along side or over the top of each device to be controlled to the area of the front where the remote control sensor is located. 3. Place the emitter end in front of the remote control sensor of the device to be controlled. The emitter bulb should face the remote control sensor. This bulb emits infrared light in a cone shaped pattern. The bulb needs to be placed far enough from the remote control sensor to allow the cone pattern to include the sensor. The remote control sensor is usually behind the plastic window of the front display panel. It is sometimes visible when you look through the display plastic using a flashlight and is normally a round or square cutout behind the plastic. If you cannot see the sensor and the devices Owners Guide does not specify the location, you can find it by using the devices remote control. Hold the remote about 1/2 inch from the front of the device. Starting from one end of the display window plastic, press the POWER button. If the device does not respond, move the remote control 1 inch toward the center and try again. Repeat this until the device responds. Note this location then start over from the other end of the display window plastic, repeating until the device responds again. The remote control sensor will be somewhere between these two positions. This is usually enough accuracy for the placement of the IR emitters. 4. With some devices, the emitter will work better facing downward from the top of the device. Some experimentation may be needed. 5. The emitter end being used can be secured in place using double stick tape.

6. If you are not going to be using all emitter ends, place the unused ends behind the devices so that they cannot send signals to the remote control sensors.

If a single emitter end can be placed in a position that will operate more than one device, do not use a separate emitter end for the additional device. A single device receiving remote control signals from too many emitters or remote controls may not respond at all.
Connecting Compatible IEEE 1394 Devices
It is possible to connect devices to the TV that have IEEE 1394 connectors but are not compatible with the TV or with the NetCommand control system. Areas of compatibility to consider are:
Compatible IEEE 1394 Devices
When Connecting IEEE 1394 Devices
Do not loop the last device in the chain back to the TV. When the device chain is looped, the TV may not be able to work with the other devices.
1. Digital Video Signals The TV is able to decode MPEG2 video. Other types of digital video, such as DV video provided by some camcorders, must be decoded by the source device and sent to the TV as analog video or S-Video. If the camcorder uses a compatible digital control system, the IEEE 1394 cable can still provide control for the camcorder while the TV is viewing the analog video or S-Video signals. 2. Digital Audio Signals When received with video signals, the TV is able to decode Dolby Digital signals and MPEG audio signals. Other types of digital audio as provided by some digital recording devices, such as MP3 audio and DTS audio, cannot be decoded by the TV when received over IEEE 1394.
The TV may not be able to pass incompatible digital audio signals on the coaxial digital audio output, however these signals may pass on the IEEE 1394 cable to other devices.
Place devices that have only a mechanical (twoposition) power switch at the end of the chain or leave the power switch in the On position. When turned Off, IEEE 1394 signals may not be able to pass through the device to other devices. Place devices with the slowest communication speed at the end of the chain. Sometimes the communication speed will be marked near the IEEE 1394 connector with an S number. The higher the number, the faster the communication speed. This TV has a communication speed of S400. Devices with slow communication speed can interfere with IEEE 1394 signals from faster devices. When using NetCommand to set up a digital recording between a faster and slower device, the slower device should be the source and the faster device should be the sync. Do not use an IEEE 1394 cable longer than 15 feet between each device. This TV is an IEEE 1394a Device. IEEE 1394b is currently under development. This system will provide for longer distances and multiroom applications. Included in the IEEE 1394b systems are IEEE 1394a to IEEE 1394b converters to maintain compatibility with this TV and other IEEE 1394a devices.

NetCommand does not allow you to delete a device or change the connections for a device (like a VCR or a DVD player) if the device (input) is currently being displayed by the TV. Switch the TV to a different device from the one you are changing or deleting. To change the A/V receiver, you need to be listening to the TV speakers.

IEEE 1394 Devices and NetCommand Control
See pages 30-31 for information regarding compatible IEEE 1394 devices and connection styles. The TV is not able to control IEEE 1394 devices that use other types of control protocols. Incompatible digital audio, video and/or control information will still be able to pass from one device through the TV to another device on the network. These incompatible devices may not appear on the Device Selection menu or in the Review screen of the Edit NetCommand menu.
NetCommand Control of Digital Devices Using the Learn Feature.
Some IEEE 1394 devices such as cable boxes or satellite receivers will not have compatible digital control signals or require the use of the devices own remote control. Some of these IEEE 1394 devices will not display on-screen information through the IEEE 1394 connection and will require using an analog connection for on-screen displays. In many cases, to control these digital devices, the Learning feature of NetCommand can be used.
1. Place an IR Emitter for NetCommand in front of the devices remote control sensor (see IR Emitters, page 29). 2. On the Name for 1394 Device screen (Figure 2, page 51) use ADJUST and ENTER to check mark the Analog Connection box. 3. Select the device type on the IEEE 1394 Device Type screen (Figure 3, page 52) of DBS or similar tuning device. 4. If desired, using the ADJUST buttons enter a custom Name on the Name screen (Figure 18, page 46). 5. At the Device screen, Select Other as a manufacturer and then highlight Learn and press Next (Figure 4, page 52). 6. Follow the device learning instructions found on the screen(s) or in the Edit NetCommand section of Chapter 3. 7. The Connection screen (Figure 5, page 52) follows the learning screens. If analog connections are used, select the correct inputs. 8. Proceed with the Finish screen. This will allow NetCommand to use the learned remote control signal to control these IEEE 1394 devices. Note: When using the NetCommand learning feature for IEEE 1394 devices that do not have analog connections, the GUIDE function will require pressing GUIDE twice. The first press of GUIDE will display the TVs digital channel guide. The second press will display the program guide for the device if an IEEE 1394 Guide is available.

Some manufacturers may change their products, or they may use more than one remote control system. If this is the case, the TV remote control may not be able to operate your VCR, DVD, cable box, satellite receiver, or A/V receiver. After entering the correct codes in each position of the remote control, use the slide switch to select which product will respond when an operational button is pressed. Only one of the below devices is allowed for each slide switch position. TV position: TV, NetCommand Controlled Devices Cable/DBS/DTV position: Cable box Satellite receiver DTV receiver VCR position: VCR DVD position: DVD LD Player Audio position: A/V receiver Mitsubishi CD player If you have a Mitsubishi A/V receiver, the audio position may be used in conjunction with select Mitsubishi CD players. Your audio position must be programmed to 010. When your remote control has been programmed to operate another manufacturers product, the function performed on each layer can vary. The most common functions are: VCR POWER CHANNEL up/down PLAY REC PAUSE STOP FF/FWD REW/REV Mitsubishi VCRs will be compatible with some additional buttons Cable Boxes and Satellite Receivers POWER CHANNEL up/down 0-9 number buttons (on some models) ENTER (on some models) CANCEL (on some models) ADJUST up/down/ left/right (on some models) GUIDE (on some models) A/V Receivers POWER VOLUME MUTE Mitsubishi A/V Receivers Direct Input Selection buttons: numbers, SQV and QV (on some models) Mitsubishi CD Players (not all functions for all models) PLAY FF/FWD REW/REV PAUSE STOP DVD and Laser Disc Players (not all functions for all models) POWER MENU 0-9 number buttons (on some models) PLAY STOP ARROW up/down/left/right (on some models) FF/FWD REW/REV PAUSE CANCEL (on some models) ENTER CHANNEL (on some models)

Table 1-1: V26 Chassis Series Models The new V26 Chassis types are all Integrated HD/Cable Ready TVs. There are three V26 chassis types, V26, V26+ and V26++. The specific models for each chassis type are given in Table 1-1. All of the models are table top models, but matching bases are available for each model. The 52 inch model for each chassis type is shown above, with it's matching base. All models feature: Integrated HD/Cable Ready Circuitry 1-1 DLPTM Light Engine CableCARDTM Slot Memory Card Reader HDMI Input
The V26+ models add: Anti-Glare Diamond Shield TV Guide On Screen (when available) The 26++ models also include HD PVR (High Definition Personal Video Recorder) with a 120 GB Hard Disc Drive.
The HDMI (High Definition Multimedia Interface) video format is basically the DVI (Digital Visual Interface) format. HDMI adds up to 8 channels of digital sound transmission. It also includes an additional serial bus that may be used for status and control purposes. Although the HDMI format is similar to DVI, the connectors are different. Figure 1-1 shows HDMI plug and

socket connectors. DVI to HDMI adaptors are available so DVI equipmeht can be connected to the TV. The CableCARD feature is the basis for the new regulation for Plug and Play Cable Standard. Figure 1-2 illustrates the typical CableCARD. Both HDMI and CableCARD were described in detail in the V25 Technical Description so it will not be repeated in this book.

Figure 1-3: Rear Panel Inputs and Outputs 1-2
Figure 1-3 shows the Rear Panel location of the HDMI input socket and the CableCARD Slot. Note in Figure 1-3 there are only two RF Antenna Inputs, instead of three. Signal input to ANT 1 is amplified and directed to both the Sub and Main Tuners. The Main Tuner can process either NTSC or ATSC (HD) signals. The Sub Tuner processes only NTSC signals, mainly as a sub picture source. The ANT 2 input connects directly through the Antenna Relay, to the Main Tuner. Figure 1-4 is a simplified schematic of the RF Antenna Splitter. The OOB (Out of Band) Tuner is used when cable information and On Screen Channel Guides are available. This feature is only available on V26++ models. It utilizes a 120 GB Hard Drive (HDD) to record digital signals from either the Antenna Inputs or 1394 Inputs: SD digital channels HD digital channels 1-3

1394 digital signals. It can also record analog 480i signals from the: Antenna Inputs External Composite Video Inputs External S-Video Inputs Analog 480i signals are converted to digital and then MPEG-2 compressed before recording on the HDD. The PVR also features "TV Pause" and up to 30 minutes of the current program is recorded. This enable a rewind feature for up to 30 minutes and the TV Pause feature. Although the basic principles have not changed, a quick review of Digital Light Processing system may be in order. Figure 1-5 illustrates the Overall DLP System. A light source is directed through a RGB Color Filter wheel. and is directed to the reflective surface on a DMD IC (Digital Micromirror Device). Light from

the DMD is directed through a Projection lens to the Projection Screen. Figure 1-6 shows a close up of a DMD IC. What appears to be a single mirror on the IC is actually close to one million individual mirrors, refer to Figure 1-7. Figure 1-8 shows that the tilt of each mirror is controlled by changing tilt to either 10 degrees. The tilt of the mirror determines if the light from the mirror passes through the Projection Lens to the screen (light pixel), or to a light absorber (dark pixel), refer to Figure 1-9. -10
Figure 1-6: Digital Micromirror Device
Figure 1-7: Micro Mirrors 1-4
Figure 1-8: 10 Degree Mirror Tilt
Figure 1-9: Light Pixel / Dark Pixel Although the basic fundamentals still apply, the Light Engine has been improved and is much smaller than in previous models. Also the light path from the Projection Lens to the screen has been changed. 1-5 Figure 1-10 illustrates the Light Path in V26 models. The light from the Light Engine Projection Lens is now directed toward a small mirror in the front of the cabinet.

Light Path Changes

From the small mirror the light is reflected to the conventional large mirror and then to the projection screen. In previous DLP models the small mirror was not used.
Figure 1-11 shows the V26 Light Engine. Although not evident in Figure 1-11, it is much smaller that the Engine in previous models. The Engine is supported by an
Adjuster Assembly which includes the picture rotation adjustment screw. Figure 1-12 illustrates the front and back sides of the small mirror. The position of the small mirror is controlled by the adjustments on the back side of the mirror. These adjustments control Horizontal and Vertical Keystone distortion. In nearly all cases no adjustments are required during servicing. The only time adjustments may be required are when the Chassis or Light Engine has been replaced. NOTE: Warranty payment for adjustments is only valid if the Chassis or Light Engine has been replaced.

Servicing the V26 series of models is Down to Major Component Replacement Level Only. The major components in V26 models are the: Chassis Light Engine Lamp Ballast Hard Drive (V26++ only) Figure 1-13 shows the location of the three main major components used on all models. Sub Assemblies can be ordered separately, such as: Card Reader Cooling Fans Front Panel PWBs

A certain amount of disassembly is required before the mechanical adjustments can be perform. The cabinet COVER-BACK and Rear Plate must be removed. Refer to Chapter 2 for the back removal procedures.

Mechanical Adjustments

The Front cover must be removed to give access to the Light Engine Adjuster assembly, and the small mirror adjuster assembly. Figure 4-4 illustrates Front Cover removal on the V26 and V26+ models. Figure 4-5 shows the required Front Cover disassembly on the V26++ models.

Figure 4-6 shows the location of the Rotation Adjustment and the Rotation Locking screws on the Light Engine Adjuster. Figure 4-7 shows the location of the Keystone adjustments and locking screws on the small mirror adjuster. Rotation Adjust From Figure 4-6 the Rotation Locking Screws are on the front of the Light Engine Adjuster, and the Adjust screw is on the left side, from the rear. Neither the locking or adjust screws are as accessible as shown in Figure 4-6.
For all mechanical adjustments: Locking screws are brass. Adjustment screw are black. (A 4mm Allen wrench is needed to turn Adjustment screws.) The Rotation Locking Screws must be accessed from the front of the unit. Referring to Figure 4-8, the two brass Rotation Locking Screws are behind the sponge that surrounds the projection lens. Push the sponge upwards to expose the Locking Screws. Loosen both
brass Locking Screws before attempting to adjust picture rotation. From the rear of the TV, the Adjustment screw is located on the left side of the adjuster assembly , refer to Figure 4-6. A mirror must be used to make this adjustment since the screen is not visible from the rear of the set. When the adjustment is complete, tighten both Rotation Locking screws.
Keystone Adjustments The Keystone locking and adjustment screws are easier to access. Both are accessible from the front, refer to Figure 4-9. Loosen the two brass locking screws before attempting the adjustment.
After completing the adjustments, tighten both locking screws. As an added protection, apply Locktite to the Adjustment screws.

CN2 CONNECTOR

Lamp Trouble Shooting Procedure 1) Unplug the CN2 connector on the Lamp ballast, refer to Figure 5-2. 2) Connect a DVM between pins 1 and 3 of CN2 connector. 3) Check the voltage when the set is first turned On. If 340VDC it points to a Lamp Ballast problem. If the voltage is missing or incorrect, suspect the chassis.
Figure 5-2: Measuring Ballast Supply Refer to page 2-6 in Chapter 2 for the procedure to access the PCB-POWER. To turn the set On, the Exhaust Fan must be plugged in, and the Lamp and Filter Covers must be installed. Table 5-4 lists the key voltages to be measure on the PWB-POWER. Figure 5-3 shows the Test Point locations on the PWB-POWER. Use the Voltage Table and Test Point Locations to check for abnormal voltages. If all voltages are missing.check fuse F9D00. Abnormal voltages indicate a problem on the PWB-POWER.
