1.-SAFETY INSTRUCTIONS
Read this page before doing any operation of adjustment, maintenance or repair the TV set described.
Only skilled personnel of Sanyo Technical Service should do the adjustment, maintenance or repair of TV set.
1.1.- WARNING.
For the correct and safe use of the TV set, it is essential that the service personnel follow the process of safety
generally accepted and the safety precautions specified in this manual.
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 side of the converter transformer of the set.
1.2.- PRECAUTION AGAINST X-RAYS.
The primary source of X-RADIATION in the television receiver is the picture tube. The picture tube is specially
constructed to limit X-RADIATION emissions. For continued X-RADIATION protection, the replacement tube must be
the same type as the original including suffix letter. Excessive high voltage may produce potentially hazardous X-
RADIATION. To avoid such hazards, the high voltage must be maintained within specified limit. If high voltage exceeds
specified limits, take necessary corrective action. Carefully follow the instructions for +B1 volt power supply
adjustment, and high voltage adjustment to maintain the high voltage within the specified limits.
COMPLIANCE TO STANDARDS
All of those marked with Xor must be
replaced with original parts
WARNING! This TV set contains components which
are particularly sensitive to static electricity (ESD).
It is recommended that all due precaution be taken
handling integrated circuits and semiconductors.
1.3.- Recommendations to protect our environment
Stand-by mode: In order to save energy and to maintain an optimum picture quality, it is advisable to switch off the TV
using the ON/OFF button located at the front of TV set.
Used batteries: The batteries in the remote control of these models do not contain mercury. However, SANYO
recommends that you do not dispose of used batteries in domestic refuse. Please, contact your dealer or your local
authorities for information regarding the disposal of used batteries or your nearest collection point.
Recommendation about the end-of-life: These SANYO TV sets have been designed and manufactured using high
quality materials which can be recycled and reused. In the future, when the life cycle of these sets come to an end,
specialised companies can disassemble it and reuse certain materials. This reduces the impact of waste in our
environment. Please, contact with your local authorities for information regarding the disposal of your set when the
time arrives. Help us to conserve the environment we live in!

3.-SPECIAL MODE FOR FACTORY
The factory mode is a special TV working mode, thought to aid the manufacturing process and it is identified by the
message “FAC”. This mode is not intended for customer use..
The Factory mode differences with respect to normal mode are the followings:
1. The TV set does not pass to standby mode after 10 min. without aerial signal input. Instead it remains
switched on.
2. The adjustments speed is four times quicker.
3. The standby mode is disabled.
To take TV set out of Factory mode, push the key of remote control.
4.-DESCRIPTION OF HOTEL MODE
By defect the TV set switches on with the program in which is was switched off, but it is also possible to force it to
switch on in a program that can be chosen between the 1 and 8 or AV.
The TV set has a special mode of operation that is adapted for use in hotels, hospitals, etc. In this case the
maximum volume level is limited to the volume chosen when the hotel mode is enabled. Furthermore, in this mode it
is not possible to do channel searching neither to modify the fine tuning control. Additionally there is the “Hotel
Rental” mode in which it is only possible to change the program with the remote control, and it is not possible to do
so with the front keys.
These software configurations are stored in the non volatile memory and therefore they remain even though
the TV set is disconnected from the power supply. The Hotel mode configuration can be changed by pushing the SET
front key and without loosing it, pushing the key of remote control. In the case of Rental mode, the modification
procedure is the same as above but it is necessary to previously set the colour control to zero. When all this is done,
the following indication appears on the screen:
00 HOTEL
The first, most significant digit indicates weather Hotel mode is chosen or not
0 êNormal mode
1 êHotel mode
2 êHotel Rental mode
The last, least significant digit indicates the programme in which the set switches on
0 êThe same as it was selected when the TV set was switched off.
1 êAlways programme position 1.
2 êAlways programme position 2.
..........
8 êAlways programme position 8.
9 êAlways AV mode.
The wanted code should be introduced with the numerical keys of remote control. Always to push the complete code.
Example:
00 êNormal mode. Switches on with the same programme selected when the TV set was switched off.
10 êHotel mode. Switches on with the same programme selected when the TV set was switched off.
11 êHotel mode. Always switches on in programme 1
21 êHotel Rental mode. Always switches on in programme 1.
09 êNormal mode. Always switches on in AV mode
5.-ACTIVATION OF THE INITIAL AUTOMATIC CHANNEL-SEARCH.
In order to reset the initial automatic channel-search function, enter the tuning menu by keeping pushed the frontal
SET key for a few seconds. Afterwards select the AUTO tuning mode by pushing several times the + or - key. Then
push the Mkey to start searching and switch-off the TV set before any station is found. When the TV set is switched
on again it will remain in the same situation as when it was switched off.

8.1.- NOTES ABOUT THE ADJUSTMENT:
In case of doing several adjustments follow the adjustment order in this table, for example, the adjusts Nº2 (AFC detector and AGC) prevails over the Nº6 (FOCUS), adjustment Nº5B (G2) prevails over the Nº5C (Cut-off).
ŒFactory picture control normal has the following OSD positions:
•Brightness: 34 (Push key “+” 34 times starting at minimum position)
•Contrast: 57
•Colour:32
•Sound:34
•The service line is obtained by connecting a resistor of 100 Ωfrom the test point (R718-C713) to ground. If it is shorted to ground directly, the TV set might pass to Stand-by (due to actuation of the deflection circuit protection).
ŽThere can be found 2 positions of the L201 core for which the voltage in R211 is of 3,5V, but the only correct position is that in which that the voltage goes up as the core is introduced in the body of de L201, and the picture is
acceptable.
