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

®

A2DP Audio Streaming iPhone

®

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

3D

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

More options may be available in the future.

on the market that can be used.

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

Introduction

Reliability and Serviceability Technologies—Simplified!

If one word could be used to describe the reliability and serviceability technologies in Mitsubishi’s 2011-

2012 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 procedure 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.

TROUBLESHOOTING

The Down to 1 strategy is to have set troubleshooting methods that will best ensure an accurate diagnosis as quickly as possible. The following troubleshooting methods will help the service technician gain the

Down to 1 advantage.

USER LEVEL RESETS AND INITIALIZATION

As in previous models, many symptoms (customer generated or intermittent) may be resolved by performing a reset or initialization. Many of these functions are available to the customer. Asking the user to perform these resets may eliminate the need for a service call. If the exact nature of a symptom is unknown, it’s best to have the customer perform the procedures in a specific order to minimize the number of settings that will be affected. The procedures, order and method are:

1. System Reset - Press and hold the <POWER> button for 8 seconds. Or remove and re-apply power.

2. A/V Reset by Input - Select the Input to be reset. Press remote <MENU> Select “Audio/Video”

Select “AV Reset “ <ENTER>

3. A/V Reset all Inputs - Press side panel <INPUT> and <VOL



> buttons at the same time and hold for 10 seconds.

4. Initialize (User Level) - Press remote <MENU><1-2-3><ENTER>.

If a user level reset does not correct the problem, it may be necessary to perform a Service Level Initialization from the Option Menu as part of a service call.

PICTURE PERFORMANCE COMPLAINTS

Like many Mitsubishi models, the V46 chassis has a “Test Picture” that can be accessed from the customer menu. Press <MENU> select “Global” then “Test Picture.” A photograph of the “Lady” will be displayed. If a TV picture performance problem exists, it should be evident. Otherwise, the test picture will have demonstrated that the set is capable of a quality display and the problem is likely due to a signal source or other external cause.
