CHAPTER 2. IMPORTANT SERVICE NOTES
[1] IMPORTANT SERVICE NOTES
Maintenance and repair of this receiver should be done by qualified service personnel only.
1. SERVICE OF HIGH VOLTAGE SYSTEM AND PICTURE TUBE
When servicing the high voltage system, remove static charge from it by connecting a 10K ohm resistor in series with an insulated wire (such as a test
probe) between picture tube dag and 2nd anode lead. (AC line cord should be disconnected from AC outlet.)
1) Picture tube in this receiver employs integral implosion protection.
2) Replace with the same type number of picture tube for continued safety.
3) Do not lift picture tube by the neck.
4) Handle the picture tube only when wearing shatterproof goggles and after discharging the high voltage completely.
2. X-RAY
This receiver is designed so that any X-Ray radiation is kept to an absolute minimum. Since certain malfunctions or servicing may produce potentially
hazardous radiation with prolonged exposure at close range, the following precautions should be observed:
1) When repairing the circuit, please make sure do not increase the high voltage of the set to more than 26.0kV (at beam 0µA).
2) To keep the set in a normal operation, please make sure it’s function at 23.0kV ±1.0kV (at beam 1000µA). The set has been factory - adjusted to
the above-mentioned high voltage.
*If there is a possibility that the high voltage fluctuates as a result of the repairs, never forget to check for such high voltage after the work.
3) Do not substitute a picture tube with unauthorizerd types and/or brands which may cause excessive X-ray radiation.
3. BEFORE RETURNING THE RECEIVER
Before returning the receiver to the user, perform the following safety checks.
1) Inspect all lead dress to make certain that leads are not pinched or that hardware is not lodged between the chassis and other metal parts in the
receiver.
2) Inspect all protective devices such as non-metal control knobs, insulating materials, cabinet backs, adjustment and compartment covers or
shields, isolation resistor-capacity networks, mechanical insulators etc.

CHAPTER 3. ADJUSTMENT PRECAUTIONS
[1] ADJUSTMENT PRECAUTIONS
This model's setting are adjusted in two different ways: through the I2C bus control and in the
conventional analog manner. The adjustments via the I2C bus control include preset-only items and
variable data.
1. Setting the service mode by the microprocessor.
(1). Press and hold the local key "VOL DOWN" & "CH UP" when power on the main switch,
TV will enter into the SERVICE MODE in Adjustment Mode.(The initial value of EEPROM
are automatically preset when new EEPROM is used).
Service Mode also can be reached by pressing "Service" key (code: 81 Hex)
(2). Press the CH DOWN / UP key on the remote controller to select the items
one by one in Adjustment Mode.
(3). Using the VOLUME UP/ DOWN key on the remote controller, the data can be modified.
(4). When press the local key "VOL DOWN" & "CH UP" at the same time,
it will be released from the service mode.
(5) Press the MENU key on the remote controller to enter into NVM mode.
Press MENU key again to leave the NVM mode return to Adjustment Mode.
( Not recommended to modify the data unless as listed in BUS SETUP data)
(6) Press both CH-UP and VOL-DOWN buttons on the TV set simutaneously or press
the "SERVICE" (81HEX) key again, it will switch to the NORMAL mode position, and
the microprocessor is out of the SERVICE mode.
2. Factory Presetting.
(1). Press remote controller key of code "ED"for 4 seconds, the initial values are
automatically preset.
(2). The initial data are preset as listed in page 5~8.
(3). Make sure whether the data need to modify or not (Initial data).
( Refer to BUS SETUP DATA)
Note: Once the chassis has been assembly together and in ready condition, please make
sure it's go through initialize process (see sect 2 above)
Precaution: If haven't done this initialization, malfunction might be happen.

ADJUSTMENT CONDITION / PROCEDURE
(1) Make sure the following items are in INITIAL

(a) 15 DRI-RS = 32
(b) 16 DRI-GS = 32
(c) 17 DRI-BS = 32
(d) 18 CUT-RS = 16
(e) 19 CUT-GS = 16
(f) 20 CUT-BS = 16
(f) 21 SUB BRI = 24
(g) 22 SUB CON = 59
(h) 32 CUT OFF = 25
(i) 35 BLOC= 4
(2) Switch TV to video mode, blue back off, with
no signal and press R/C to set picture into
normal condition.
(3) Go to service mode, select item 31 VSD
(dark screen display)
(4) Adjust the Screen so that cut-off line appear in
low bright, then judge that whether the cut-off
line appear in Red or Green or Blue color, in
this condition between CUT-RS & CUT-GS &
cut-BS, fix the data of the color appear in
cut-off line and adj the other two cut-off data
(Note 1) so that cut-off line color become white.
(5) Turn the screen VR of FBT so that cut-off line
just disappear
(1) WHITE (HIGH BEAM)
(In Window Pattern Signal)
First use Minolta Color Analyzer CA100, let the
gun point at Dark White position (as drawing
attach), Adj SUB-BRI until LUMINANCE Y
become 4 cd/m2, then let the gun point at
White position (as drawing attach), Adj SUB-
CON until LUMINANCE Y become: 150 cd/m2.
Adj the DRI-RS & DRI-BS until the axis of color
temperature become
12300 K X : 0.272 , Y : 0.275
(2) DARK WHITE (LOW BEAM)
Let the gun point at Dark White position, if
the color temperature data shift away from
the data adjusted in Item 1 Screen
adjustment, adjust CUT-RS, CUT GS
& CUT-BS.
Please fix the first colour appears in Screen
adj item step (4) is fixed, adj the other two
so that to obtain the similar axis as above.
