Safety Precaution for Repair

1-1 Cautions

PRODUCT SAFETY NOTICE

Many electrical and mechanical parts have special safety-related characteristics. These are often not evident from visual inspection nor can the protection afforded by them necessarily be obtained by using replacement components rated for a higher voltage, wattage, etc. Replacement parts which have these special safety characteristics are identified in this Service Manual. Electrical components having such features are identified by marking with a on the schematics and the parts list in this Service Manual.

The use of a substitute replacement component which does not have the same safety characteristics as the HITACHI recommended replacement one, shown in the parts list in this Service Manual, may create shock, fire, or other hazards. Product safety is continuously under review and new instructions are issued from time to time. For the latest information, always consult the current HITACHI Service

Manual. A subscription to, or additional copies for, HITACHI Service Manual may be obtained at a nominal charge from HITACHI SALES CORPORATION.

CAUTION

CLASS 2M LASER RADIATION WHEN OPEN.

DO NOT STARE INTO THE BEAM OR VIEW

DIRECTLY WITH OPTICAL INSTRUMENTS.

Function to correct the gradations on dark portions to make dark scenes easierto-see.

Content Protection for Recordable Media: Copyright protection function that is suitable for online distribution of music.

One type of DVD standard disc, to which writing once is possible (recordable type)

One type of CD standard disc, to which writing up to 1000 times is possible

Used for outputs of HDTV video signal format. Since signals for brightness and colors are independently handled for components signals (Y: luminance signal;

PR/PB: chrominance signals), degrading of image will be reduced.

A device that decodes the data coded and recorded on DVD Video and restores it to video and audio signals. This processing is referred to as decoding.

A difference between maximum and minimum levels of audio recorded on disc:

Measured in decibel (dB) units. If the dynamic range is compressed (audio DRC), the minimum signal level will increase and the maximum signal level will decrease: This will reduce the higher audio signal - such as burst sound - so that the low-level audio signal - such as human voice - can be heard more clearly.

Audio coding format developed by Dolby Laboratories in U.S, also simply referred as AC3 format: Supports 5-channel full-range sound and one channel for sub-woofer sound playback.

Dynamic Range Control: Adjusting the audio range of maximum and minimum levels (dynamic range) will improve audio signal when, for example, dialog is hard to hear or user is watching movies late at night.

Digital Theater System: Sound system as for movie theaters developed by US

Digital Theater Systems, Inc. The number of channels provided by DTS is the same for Dolby AC3.

Digital Versatile Disc. A huge amount of digital data for video (movie) and audio can be recorded on this disc, whose size is the same as CD.

One type of DVD standard disc, on which high-quality audio can be recorded

One type of DVD standard disc, to which writing once is possible (recordable type)

One type of DVD standard disc, to which writing up to 100,000 times is possible

One type of DVD standard disc, to which writing up to 1000 times is possible

One type of DVD standard disc, on which high-quality video and audio can be recorded

Video recording/playback standard that applies to DVD-Video, DVD-R and DVD-

RW

Video recording/playback standard that applies to DVD-RAM and DVD-RW:

This allows versatile editing functions, differing from the DVD Video Format.

DVD recorders normally use data that is common between images, and individually record different data for each image.

I-picture: Images recorded independently for the reference of commonly used data.

P-picture: Images created from past I-picture or P-picture

B-picture: Images created from both I and P pictures, which interact between both types

Since I-picture delivers the highest image quality, selecting I-picture is recommended when adjusting image quality.

MPEG1 Audio Layer-3: Audio data digital compression technology.

Audio is usually converted to an electrical signal and transmitted from DVD to a device such as amp: When audio is converted to a digital signal, this optical digital audio output can be transmitted on optical fiber.

Most DVD videos are produced assuming that they will be displayed on wide TV screen (aspect ratio of 16:9): If they are displayed on TV screens with 4:3 aspect ratio, 16:9 images will not quite fit on 4:3 screens. There are two ways of displaying 16:9 images on 4:3 TV:

· Pan & Scan: Cuts out the left and right ends of images and displays them on whole screen.

· Letterbox: Reproduces 16:9 images on 4:3 screens with black bands across the top and bottom of screen.

One format to play Video CD: User can select desired screens and data while watching the displayed menu screen.

This function converts interlaced images to non-interlaced images and displays them. It can play back 24-frame/second images included in DVD movie software, etc.

The video signal is separated into chrominance (C) and luminance (L) signals and transmitted to TV: This delivers clearer images.

Sampling slices audio waves (analog signal) at a specified time interval, and digitizes the levels of the sliced waves. The slicing number per second is referred to as the sampling frequency: The higher the number, the closer the sound to the original.

Secure Digital Music Initiative: This conference was established by hardware makers, the Recording Industry Association of America (RIAA) and music industry companies, to protect copyrights of musical compositions.

To make adjustment for clearer playback image, by reducing noise that appears on screen during videotape playback.

V Virtual surround

W WMA

This technology localizes sound at any position using only two front speakers, by subjecting the L and R signals to matrix operation. It uses the four transfer functions from L/R speakers located at specified positions to both ears of listener located in a specified position, taking into account the shape of head and the effect of earlobes, and the two transfer functions from any position to both ears.

Windows Media Audio: Codec that was developed by Microsoft Corporation in

USA.

Most semiconductor devices are electrostatically sensitive and therefore require the special handling techniques described under the "Electrostatic Protection

Measures" section of this service manual.

Note :

Do not use the part number shown on this drawing for ordering. The correct part number is shown in the parts list (may be slightly different or amended since this drawing was prepared).

Important safety notices :

Components identified with the mark have the special characteristics for safety.

When replacing any of these components.

Use only the same type.
