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.

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.

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
This is an I2C isolation device
IC8501
This is a digital to analogue converter. It is used to convert the HDMI digital audio data to analogue.
IC8502
This is a dual OP-AMP and is used to bufffer the HDMI analogue signal to the audio selector IC (IC1271)
