Recommendations on Installation

Provide an ample amount of space around the display. To prevent internal heat buildup sealing off the display, make sure to ensure proper ventilation by leaving open the mini-

mum amount of space around the display, as illustration below.. The ambient temperature must be 0dC to 35dC (32dF to 95dF). Be careful when installing the display near a ceiling. The

temperature there can become much higher than the normal, lower-level room temperature.. Regarding the installation of hardware such as brackets, screws, or bolts, we cannot specify the products. For actual

installation, contact your local Sony Sales Offi ce/Service Center.. While the display is on, a certain amount of heat builds up inside. This can cause burns. Avoid touching the top or rear of

the display when it is powered on or just after it has entered standby mode.

When mounting the display horizontally When mounting the display vertically

1-6. Lead-free Solder

Boards requiring use of lead-free solder are printed with a lead free mark (LF) indicating the solder contains no lead.(Caution: Some printed circuit boards may not come printed with the lead free mark due to their particular size.)

: LEAD FREE MARK

m. Be sure to use the lead-free solder for the printed circuit board printed with the lead free mark.. The lead-free solder melts at a temperature about 40 dC higher than the ordinary solder, therefore, it is

recommended to use the soldering iron having a temperature regulator.. The ordinary soldering iron can be used but the iron tip has to be applied to the solder joint for a slightly

longer time. The printed pattern (copper foil) may peel away if the heated tip is applied for too long, so be careful.

Section 3Circuit Description

3-1. Microcontroller

A microcontroller is mounted in IC400 (A board). It controls the whole block. Firmware is stored in IC600, and each setting data is stored in IC1401. Two external SDRAMs (IC601 and IC602) of 128 MB are connected for various processing (including image processing).

3-2. Input Signal Selection

A signal can be input from DVI and Option as a digital signal. An RGB/component signal can be input from the HD15 terminal as an analog signal, and a composite signal can be input from the BNC terminal. Moreover, an S-video signal can be input from the S-video terminal, and an RGB/component signal can be input from Option.The digital signals from the standard DVI terminal and from Option are selected using IC203 and input to IC400. The RGB/component signal from the standard HD15 terminal is received by transistor, and then input to IC400. The RGB/YUV signal from Option is input to IC400. The composite/S-video signal is selected using IC4 and input to IC400.An audio signal from OPTION DIGITAL is output from IC203 and converted once from digital to analog using IC700, and then input to IC4. Other analog audio signal is input to IC4 and is selected.The COMPOSITE OUT is loop-through from the COMPOSITE IN, and the signal is output as it is when the power is standby and AC is OFF state. The HD 15 Out is active-through, and the signal is output only when the power is ON.

3-3. Video Decoder and Filter Circuits

The video decoder is built into IC400. The selected video signals are decoded using various fi lter circuit. In addition to a main path, the video decoder has a sub-path for PIP/PAP. The main path and sub-path have different fi lter circuit confi guration. A slight difference appears in the image pattern during PIP/PAP. Picture quality is all set in this IC400.

3-4. Audio Circuit

Each analog audio signal is selected by IC4 and divided into two; one for the Audio output and the other for the Speaker output. The signal for the Audio output is buffered in transistor and output from the Au-dio-out connector as the monitor out. The signal for Audio is directly output from IC4. Therefore, the input signal is output as it is as the monitor out without being processed by the Volume control, sound effect, etc.On the other hand, the signal for the Speaker output is digitalized by the A/D converter (IC701) and it is output from Speaker_out via the sound processor (IC704) and Audio AMP circuit (IC705). The sound processor (IC704) performs the settings of the sound quality, volume, delay, etc.

3-2 FWD-S42H1

3-5. Connection with LCD Panel

A signal is connected with the LCD panel using an LVDS signal and output from IC400 via the connector (JK502).

3-6. Network

A network function is controlled using IC1103. It internally communicates with a main microcontroller (IC400) using an RS-232C protocol.For connection with the outside, a network function is connected to IC1103 via IC1000. The fi rmware of IC1103 is stored in IC1002 and processed using work memory (IC1001).

Section 4SNMP

4-1. SNMP

FWD-S42H1/S47H1 installs SNMP (Simple Network Management Protocol). SNMP is a standard protocol for network management that was standardized in IETF (Internet Engineer Task Force).By using SNMP, the management information of equipment connected to a network can be gotten via a network. The information of multiple equipment gotten using SNMP can also be unitarily managed by using SNMP management software.The equipment corresponding to SNMP has a management information database called MIB (Manage-ment Information Base) in the inside of equipment. In SNMP, the bidirectional communication of data contained in MIB is realized between a management system and management object system that exist in a network.In MIB, there is the standard MIB prescribed by RFC. Especially, MIB-2 (formal name: MIB-II) is its representative MIB. MIB-2 was established to manage a network. MIB-2 is installed in much network equipment such as a PC, router, and switch as a standard feature. This unit installs this MIB-2.Monitoring and monitored sides exist when equipment is monitored via a network using SNMP. The monitoring side is called an SNMP manager. It is mainly constituted by the software of PC. For the monitored side, a module called an SNMP agent is installed. SNMP-compatible equipment transmits MIB information to an SNMP manager via this SNMP agent. This unit installs this SNMP agent. This unit can realize the communication with a general-purpose SNMP manager using this SNMP agent.Basically, an SNMP agent replies only when an inquiry is sent from an SNMP manager.The SNMP manager periodically inquires the equipment, which it manages, about MIB information. This way to get information is called polling. In polling, equipment replies using a response command when an SNMP manger sends a request command to equipment. By polling, therefore, equipment can be monitored without applying a high load to the equipment.On the other hand, notifi cation can also be done from the equipment side to an SNMP manager. This noti-fi cation is called a trap. Using this trap, when a serious trouble occurred in equipment, it can be notifi ed to the SNMP manager in a short time.This unit is compatible with the two polling and trap protocols described above. Equipment can be effi ciently monitored using these protocols.

SAFETY CHECK-OUT

After correcting the original service problem, perform the following safety checks before releasing the set to the customer :

Check the metal trim, metallized knobs, screws, and all other exposed metal parts for AC leakage. Check leakage as described below.

LEAKAGE TEST

The AC leakage from any exposed metal part to earth ground and from all exposed metal parts to any exposed metal part having a return to chassis, must not exceed 3.5 mA. Leakage current can be measured by any one of three methods.

1. A commercial leakage tester, such as the Simpson 229 or RCA WT-540A. Follow the manufacturers instructions to use these instruments.

2. A battery-operated AC milliammeter. The Data Precision 245 digital multimeter is suitable for this job.

3. Measuring the voltage drop across a resistor by means of a VOM or battery-operated AC voltmeter. The limit indication is 5.25 V, so analog meters must have an accurate low-voltage scale. The Simpson 250 and Sanwa SH-63Trd are examples of a passive VOM that is suitable. Nearly all battery operated digital multimeters that have a 20 V AC range are suitable. (See Fig. A)
