2 SAFETY INSTRUCTION
WARNING: Only competent service personnel may carry out work involving the testing or repair
of this equipment.
X-RAY RADIATION PRECAUTION
1. Excessive high voltage can produce potentially hazardous X-RAY RADIATION. To avoid
such hazards, the high voltage must not exceed the specified limit. The nominal value of the high
voltage of this receiver is 25KV at max beam current.
The high voltage must not, under any circumstances, exceed 29KV.
Each time a receiver requires servicing, the high voltage should be checked. It is important to
use an accurate and reliable high voltage meter.
2. The only source of X-RAY Radiation in this TV receiver is the picture tube. For continued
X-RAY RADIATION protection, the replacement tube must be exactly the same type tube as
specified in the parts list.
SAFETY PRECAUTION
Potentials of high voltage are present when this receiver is operating. Operation of the receiver
outside the cabinet or with the back board removed involves a shock hazard from the receiver.
Servicing should not be attempted by anyone who is not thoroughly familiar with the precautions
necessary when working on high voltage equipment.
Discharge the high potential of the picture tube before handling the tube. The picture tube is
highly evacuated and if broken, glass fragments will be violently expelled.
If any Fuse in this TV receiver is blown, replace it with the FUSE specified in the Replacement
Parts List.
When replacing a high wattage resistor (metal oxide film resistor) in the circuit board, keep the
resistor 10 mm away from circuit board.
Keep wires away from high voltage or high temperature components.
This receiver must operate under AC 230 volts, 50 Hz. NEVER connect to a DC supply or any
other voltage or frequency.
PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in this equipment have special safety-related
characteristics. These characteristics are often passed unnoticed by a visual inspection and the
X-RAY RADIATION protection afforded by them cannot necessarily be obtained by using
replacement components rated for higher voltage, wattage, etc. Replacement parts which have
these special safety characteristics are identified in this manual and its supplements, electrical
components having such features are identified by designated symbol on the parts list. Before
replacing any of these components, read the parts list in this manual carefully. The use of
substitutes replacement parts which do not have the same safety characteristics as specified in
the parts list may create X-RAY Radiation.

3.6 NVM default setting
The purpose of this message, when you change a virgin EEPROM, is to allow to modify
the NVM DATA to desired values.
1 - Introduction :
The NVM default valus are fixed for the user, but for flexibility in service, these data are stored in
NVM and can be changed when the TV set is in a special mode call "NVM EDITOR". This mode
can only be access from "FACTORY" mode.
2 - Entering into "FACTORY" mode.
To switch the TV set into FACTORY mode, use the factory remote control, and press on “SVC”
key. The factory menu will appear on the screen, showing “FACTORY” , plus other relevant
information like software version and date.
WARNING : When in "FACTORY" mode you should not press any key other than the keys
described in the procedure below. Unwanted key stroke could misadjust the TV set.
3 - Entering into "NVM EDITOR" mode.
To switch the TV set into NVM EDITOR mode, use the user remote control, and press on
“PICTURE/OK” key. The NVM EDITOR window will appear on the screen. This mode allow you
to access all data stored in NVM. The current NVM address is given in column "ADDR." in both
DECimal and HEXadecimal format. The column DATA gives the value contained at selected
address in both DECimal and HEXadecimal format.
4 - Navigation in "NVM EDITOR" mode.
Use Program Up/Dwn keys to select the desired address. Use Volume Up/Dwn keys to change
the data at selected address. You must press "PICTURE/OK" key to store value after
modification.
The data can be adjusted between 0 and 63.
5 - Exit "NVM EDITOR" mode.
To switch the TV set back into FACTORY mode, use the user remote control, and press on
“MENU” key.
The factory menu will appear on the screen, showing “FACTORY”.
6 - Exit "FACTORY" mode.
To exit "FACTORY" mode, use the factory remote control, and press on “SVC” key.
The factory menu will disappear from the screen.

3.7 TV SET ALIGNMENT
3.7.1 G2 ALIGNMENT
- Tune a colour bar pattern.
- Find the “G2 – SCREEN” item in service mode.
- Adjust screen volume (on FBT) to bring the cursor to central position(Green).
3.7.2 WHITE BALANCE
- Select a dark picture and adjust RED BIAS and GRN BIAS to the desired colour temperature.
- Select a bright picture and adjust RED, GRN and BLUE GAIN to the desired colour temperature.
3.7.3 FOCUS
Adjust the Focus volume (on FBT) to have the best resolution on screen.
3.7.4 VERTICAL GEOMETRY
Adjust V. LINEAR (linearity), S CORRECT (S. Correction), VERT SIZE (Vertical amplitude),
VERT CENT (vertical centring) to compensate for vertical distortion.
3.7.5 HORIZONTAL PICTURE CENTRING
Adjust HOR CEN (Horizontal centre) to have the picture in the centre of the screen.
3.7.6 AGC
- Make sure option bits are correct for the tuner fitted on the chassis (See above how to change
option bits).
- Adjust the antenna signal level at 62 dBµV
- Tune a colour bar pattern.
- Find the “AGC” item in service mode.
- Press the key “OK” on the remote keypad and wait until AGC level stabilise to the optimum
value.
- Alternatively, use “Vol Up/Dwn” keys to adjust manually to the desired Tuner Take Over Point
(TOP).
