Consumers worldwide are using PCs to create their own collections of music, photos and even video by burning them onto CDs. But how these collections can be experienced across different dev

30、ices can be confusing to navigate, time consuming to access for a DVD player, and be incomplete in terms of music information available to the customer. HighMAT offers a solution to this growing consumer problem. HighMAT dramatically improves the digital media experience on consumer electronic devic

31、es by delivering a simple, standardized approach that allows consumers who have created personal collections of digital music, photography and video on their PC to: Create a HighMAT CD or DVD which can be easily played back on consumer electronics devices such as CD and DVD players, and car stereos.

32、 Move digital media files (using recordable media such as CD-R and CD-RW) between the PC and various playback devices such as CD and DVD players. A new standard for creating personal media on consumer electronic devices, HighMAT enable easier and more seamless interoperability between Windows PCs an

33、d devices designed for your living room, or the car. 10 SA-HT730GCP 8.3.2. Why take advantage of HighMAT? A Problem Defined:Today, when consumers create their own digital audio, video or photo collections on CD-R or other physical formats, there are numerous, inconsistent ways that devices read the

34、data. For the consumer, the playback experience can be confusing: A Solution Created: HighMAT delivers a better digital media access experience by creating a standard approach for PCs to structure digital media on various physical formats and for playback devices to read the data. 8.3.3. Benefits of

41、r diode in the optical pickup unit may break down due to static electricity of clothes or human body. Special care must be taken avoid to electrostatic breakdown when servicing and handling the laser diode. 10.1. Cautions to Be Taken in Handling the Optical Pickup Unit The laser diode in the optical

42、 pickup unit may be damaged due to electrostatic discharge generating from clothes or human body. Special care must be taken avoid to electrostatic discharge damage when servicing the laser diode. 1. Do not give a considerable shock to the optical pickup unit as it has an extremely high-precise stru

43、cture. 2. To prevent the laser diode from the electrostatic discharge damage, the flexible cable of the optical pickup unit removed from the PCB should be short-circuited with a short pin or a clip. 3. The flexible cable may be cut off if an excessive force is applied to it. Use caution when handlin

44、g the flexible cable. 4. The antistatic FPC is connected to the new optical pickup unit. After replacing the optical pickup unit and connecting the flexible cable, cut off the antistatic FPC. 10.2. Grounding for electrostatic breakdown prevention Some devices such as the DVD player use the optical p

45、ickup (laser diode) and the optical pickup will be damaged by static electricity in the working environment. Proceed servicing works under the working environment where grounding works is completed. 10.2.1. Worktable grounding 1. Put a conductive material (sheet) or iron sheet on the area where the

46、optical pickup is placed, and ground the sheet. 10.2.2. Human body grounding 1. Use the anti-static wrist strap to discharge the static electricity form your body. 16 SA-HT730GCP 17 SA-HT730GCP Some chassis components may have sharp edges. Be careful when disassembling and servicing. 11 Disassembly

47、and Main Component Replacement Procedure “ATTENTION SERVICER” 1. This section describes procedures for checking the operation of the major printed circuit boards and replacing the main components. 2. For assembly after operation checks or replacement, reverse the respective procedures. Special reass

48、embly procedures are described only when required. 3. Select items from the following index when checks or replacement are required.
