SAFETY PRECAUTION

PRODUCT SAFETY NOTICE

SPECIFICATIONS

Product safety should be considered when a component replacement is made in any area of a receiver. Components

indicated by mark in the parts list and the schematic diagram designate components in which safety can be of

special significance. It is particularly recommended that only parts designated on the parts list in this manual be used

for component replacement designated by mark . No deviations from resistance wattage or voltage ratings may be

made for replacement items designated by mark .

!

1: An isolation transformer should be connected in the

power line between the receiver and the AC line when a

service is performed on the primary of the converter

transformer of the set.

2: Comply with all caution and safety-related notes

provided on the cabinet back, inside the cabinet, on

the chassis or the picture tube.

3: When replacing a chassis in the cabinet, always be cer-

tain that all the protective devices are installed properly,

such as, control knobs, adjustment covers or shields,

barriers, isolation resistor-capacitor networks etc. Before

returning any television to the customer, the service tech-

nician must be sure that it is completely safe to operate

without danger of electrical shock.

Mechanical Disassemblies (CE42LM4WPR-E)

1. Check points before disassembly

Check the location of tamper proof marking (Fig-1)

If the marks are removed or touched, somebody may have already disassembled the set.

This makes the warranty regarding this IP model invalid.

After finishing the service, make the set tamper proof again with silver paint.

2. Rear Plate Removal

Remove screws A (6 pcs), then remove the Terminal Cover (Fig-2)

Remove screws B (4 pcs), then remove the AV Terminal (Fig-3)

Remove screws D (20 pcs) - (Fig-6)

Remove screw C (Fig-5), then remove the Rear Plate.

N4JKT

The TV control commands are used to control a TV through RS232C from a computer.

Serial Interface Specification

Transfer Specification

1. Transmission Speed : initial setting value is 19200

2. Transmission speed can be changed by hotel mode

Connection

The designated RS232C serial cable that is provided with the LCD monitor must be used for a connection between a computer and a LCD monitor

The TV command is defined by one command / one line that starts with “C” and ends with carriage return (0x0D)

There are two types of commands:

1. Functional Execution Commands e.g. Co5[CR] (see table on following page)

2. Status Read Commands e.g. “CR0 [CR] (see table on following page)

Setting the monitor address in RS232 mode

To access hotel mode press the green button on the remote control and hold for 5 seconds. The following screen will appear

Each monitor can have a specific address e.g. 007 which helps command that monitor individually and will not affect other monitors connected to

a controlling pc.

Address format command

The adressing format command is used for operating multiple monitor sets from a single pc via the RS232 command line. If you set your monitor

address to ‘000’ it will never respond to any addressing command from the pc. If the address from the pc is ‘FFF’, all monitor sets will execute the

command.

The address format command is defined by one command, one line which starts with ‘A’ and ends with carriage return (0x0D). An address is

added at the top of a control command.

Example:

Functional execution command: “A001C05” [CR] means the address is 001 and the control command is C05

Status read command: “A001CR0” [CR] means the address is 001 and the command is CR0

The monitor can set its own address in the hotel option (see above). The address range is 000 - 999, the default address will be 000.

The baud rate indicates the unit transfer speed of data from the pc the the monitor sets.

IC Descriptions for UK4B

IC1110

This is a switching IC, NJM2233BM, which allows the sync signal input on monitor sets to be switched between pin

20 of SCART 1 (conventional) and pin 14 of SCART 1 (SIS signal). The IC takes a 5V supply and is switched by the

control line SIS.

IC1205

N4JKT

IC Descriptions for UK4B (continued)

IC6600

This is an LA5754 voltage regulator. It provides the 12v supply for the LCD panel.

IC6601

This is a BA33BC0FP voltage regulator. It converts the 5v standby supply to 3.3v.

IC6602

This is a BA09FP-E2 voltage regulator. It converts 13v to 9v.

IC6603

This is a BA12FP-E2 12v voltage regulator. It converts the main 13v supply down to 12v for the fan.

IC6604

This is a LA5754MP voltage regulator. This IC converts the main 13v supply down to 6v. IC801 can switch this IC on

and off via control line “Power 1”. Consequently all supplies developed from this 6v will also be switched (see power

architecture diagram on page 8)

IC6605 / 6 / 7 / 8 / 9 / 10

These are voltage regulators which convert the switched 6v supply down to 5v, 3.3v and 1.8v.

IC6613

This is a TC7SH02 2-INPUT NOR GATE. This IC controls the 5v power to the LCD panel. It is switched via control

lines “Power 4” and “Panel on”.

IC701

This is a THC63LVDM83R LVDS converter IC. This IC converts 3 sets of 8 bit data (R, G & B) into 4 channel and

clock data stream to the LCD panel.

IC8001

This is a HDMI receiver / convertor. HDMI data from K1006 is fed into this IC. The IC then extracts the video and

audio in digital format and sends the data to IC801. Audio data is converted to analogue via IC8501

IC801

This IC is the main control IC for the entire TV.

It incorporates:-

1) CPU for control and on-screen graphics presentation.

2) Video signal processor for controlling picture presentation and quality.

3) LCD scaler for converting different resolutions to the resolution of the LCD.

4) 100 page text decoder.

5) Stereo sound decoder.

6) Multi-system decoder (PAL, NTSC, SECAM etc.)

IC802

This is an 8K x 8 bit EEProm. It is used to store all the calibration data and user settings. When a new IC is fitted,

the CPU (IC801) will detect it and initialise the IC to the default factory settings.

IC8131

This is a 512 x 8 bit EEProm. It is used to store the resolutions that the tv is able to display along with the manufac-

turer, date of manufacture and model number. An external device (eg DVD) with HDMI will read this EEProm to

determine which resolution signal to send to the tv.

IC8141
