Introduction

This Introduction will discuss some of the newest features and technologies. The remainder of the manual is divided into 2 sections to cover the

LASERVUE and DLP Home Cinema product categories separately. While

this manual can be used as a service aid, always refer to the Service Manual for complete service information and safety instructions.

FEATURES and TECHNOLOGIES

A matrix of many of the features included in the 2011-2012 product line follows. Also, several of the newest

Introduction

TECHNOLOGIES

Mitsubishi’s 2011-2012 TV product line includes several technologies either new to the market place or introduced in the recent past. These technologies include:

 3D with built in IR synchronization emitters.  Stream TV™ Internet Media  Wireless Internet Ready and Built-in Wireless Internet  Bluetooth  iPhone

A2DP Audio Streaming

Remote Control App

In addition, Mitsubishi’s Reliability and Service Technologies have evolved yet again. These technologies will be discussed further.

2011-2012 Mitsubishi TVs will support the mandatory HDMI 1.4a 3D signals intended for the United States. However, there may be some 3D sources that are not compatible with the TVs. Specifically, the TVs will support the 3D signals known as:

 Frame Packing 1080p/24Hz and 720p/60Hz (primarily from Blu-ray players and gaming consoles).  Side-by-Side in 1080i/60Hz, 1080p/24Hz/30Hz/60Hz and 720p/60Hz.  Top/Bottom in 1080p/24Hz and 720p/60Hz.  Checkerboard 1080p/60Hz.

In all cases:

(1) 3D sources must connect to the TV using the HDMI inputs or via StreamTV™ Internet Media. (2) Active Shutter 3D glasses are required in order to view 3D content. They must be synchronized

using either IR or DLP-Link. IR synchronization must use either the TV’s internal IR emitter or an external IR emitter connected to the rear of the TV.

Introduction

Stream TV™ Internet Media

Introduced last year, internet media capabilities have been expanded to many more models this year by including an Ethernet port and wireless ready or wireless internet connections. This permits instant access to an extensive library of high quality entertainment and social media content. StreamTV provides consumers with over 100 different applications.

Internet services provided by VUDU™ Apps let you access many popular on-line applications. In addition to free content, VUDU’s movie service lets you buy and rent movies through the TV. Visit VUDU.com to learn more about available movie titles, prices, and services offered. For a list of recommended routers and switches, see the Support > FAQ section at VUDU.com.

Requirements for StreamTV internet media:

 Broadband internet service (at least 2 Mbps for SD, • 4 Mbps for HD, and 8 Mbps for 1080p HDX)  Internet connection (wired or wireless).  Computer access to the VUDU.com website (required for initial account activation).  A credit card for rental and purchase transactions from VUDU’s movie service.

Wired Internet, Wireless Internet Ready and Built-in Wireless Internet

These technologies are exactly what they say they are. Requirements are as follows:

Wired: Category-5 (CAT-5) Ethernet cable connected from the LAN Port of the TV from either a router or modem providing high speed internet service. Wireless Ready: Azurewave AW-NU231 USB wireless adapter plugged into the TV’s USB port. Note: At this time, these are the only wireless adaptors available on the market that can be used. More options may be available in the future. Wireless and Built-in Wireless: IEEE 802.11n compliant wireless network router providing highspeed internet service.

Bluetooth® A2DP Audio Streaming

The Bluetooth specification for basic audio provides a frequency response designed for voice communication. Bluetooth’s Advanced Audio Distribution Profile, or A2DP, allows high-fidelity stereo audio to be streamed from the customer’s Bluetooth device to the TV. A A2DP enabled Bluetooth device (phone, media player, etc.) is required.

iPhone

Remote Control App

Owners of Apple’s iPhone or iPod Touch devices can obtain an optional App (application) that will give the device remote control capabilities. They can then control their TV over the wireless internet connection.

From a Service Technician’s Point of View…

New technologies always present a challenge to the service technician. The customer expects the technology to work to whatever expectation he has in mind. And if it doesn’t, he expects the service technician to wave his “magic wand” and make it all better. In most cases, problems are not due to a failure. The customer simply does not understand the feature’s use, capabilities, requirements or set-up. Since the Service Technician’s primary job is to repair failures, the customer problems have to be eliminated first. When receiving a customer complaint about a new technology, the best first course of action is to point the customer to Mitsubishi’s Operational Assistance department at 800-332-2119.

Introduction

Reliability and Serviceability Technologies—Simplified!

If one word could be used to describe the reliability and serviceability technologies in Mitsubishi’s 20112012 TV products, it would be simplified.

LASERVUE

The second generation V42 chassis is a complete redesign of the V40. It is, well... simplified. How?

 The Screen is stationary. No motors. No moving parts. No shipping screws.  The Fiber Optic Cables have been eliminated. No optical connectors.  The Mirror is flat.

DLP Home Cinema

 The Chassis is held in the cabinet by only 4 screws. And, disassembly is simplified by a reduction

in the number of screws necessary to remove the PWB-MAIN. Comparing the base models V43 to V41 shows a screw reduction of more than 42%. The high end models screw reduction is more than 32%. And the V41 seemed simple!

 The Optical Engine assembly has been redesigned to a more compact design and is held in the

cabinet by only 3 screws.

 The PWB-BALLAST is held in place by a single clip.  The screw on DVI Cable has been replaced by a finger locking LVDS Ribbon Cable.

DLP Home Cinema

 The Self Diagnostics feature is self activated when the set is in the shut down condition. No pro-

cedure necessary to obtain an Error Code.

 The Error Code read-out is now color coded. It’s now simplified to the point where a customer

can read the Error Code.

 Software updates can be performed on-line automatically (Internet Media models).  Bluetooth circuit is on a separate PWB to simplify troubleshooting.

SAFETY

Like the first generation V40 LASERVUE chassis, the V46 chassis includes laser technologies that have safety requirements that are separate and different than those in other TVs. Prior to servicing this type product, it is important to read and understand all safety requirements. The V40 Technical Training Manual includes a section on the Fundamentals of Laser and Laser Safety. It is available for download from new.3diamonds.com. In addition, the laser safety requirements specific to the V46 chassis are repeated from the Service Manual here. Refer to the Service Manual for all other safety instructions.

SAFETY PRECAUTIONS

NOTICE: Observe all cautions and safety related notes located inside the receiver cabinet and on the receiver

chassis.

WARNING:

1. Operation of this receiver with the covers removed presents both a shock hazard and a hazard from laser ra diation. Work on the receiver should not be attempted by anyone who is not thoroughly familiar with the precautions necessary when working on high voltage and laser based equipment.

2. When service is required, observe the original lead dress. Where a short-circuit has occurred, replace those components that indicate evidence of overheating.

CAUTION:

This TV is a CLASS 1 laser product. This TV poses no risk to eyes or skin during normal use. An exposure hazard may exist only if the protective housing is removed.

This TV contains a CLASS 4 laser device, which by itself may be hazardous. However, this TV incorporates a protective housing, optics and electronics such that there should be no exposure to unsafe levels of laser light during normal operation and proper service.

This TV is in compliance with the requirements of IEC 60825-1 Ed. 2(2007).
