SHARP CORPORATION
The chassis in this receiver is partially hot. Use an isolation transformer between the line cord plug and power recep-
tacle, when servicing this chassis. To prevent electric shock, do not remove cover. No user-serviceable parts inside.
Refer servicing to qualified service personnel.
In the interests of user-safety (Required by safety regulations in some countries) the set should be restored to its
original condition and only parts identical to those specified should be used.

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 tube of the same type number 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, be sure not to increase the high voltage to more than 30.0kV (at beam 0 μA) for the set.
2. To keep the set in a normal operation , be sure to make it function on 27.0kV ±1.0kV (at beam 1,000 μA) in the case of the set. 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 unauthorized types and/or brands which may cause excess 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-metallic control knobs, insulating fishpapers, 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 adjust-
ments via the I2C bus control include preset-only items and variable data.
CAUTION: MAKE SURE TV SET IN “NORMAL CONDITION” BEFORE SWITCH TO SERVICE MODE FOR ADJUSTMENT.
1. Setting the service mode by the microprocessor.
i) Short JA 304 & JA 307 , then tv set will switch to the SERVICE mode position, and the microprocessor is in input mode. (Adjustment through
the I2C bus control).
ii) Press the MENU key on the remote controller to get ready to select the mode (Adjustment mode, Setting mode, Check mode and Option
mode) one by one.
iii) Press the CH DOWN / UP key on the remote controller to select the item in Adjustment mode, Setting mode or Option mode.
iv) Using the VOLUME UP/ DOWN key on the remote controller, the data can be modified. Please wait approximately 200 msec for data storage
in EEPROM before select to another mode.
v) In Check mode the data cannot be changed.
vi) Disable the short of JA 304 & JA 307, it will switch to the NORMAL mode position, and the microprocessor is out of the SERVICE mode.
2. Factory Presetting.
i) Short JA 304 & JA 307, then turn ON the main power and release the short of JA 304 & JA 307 after raster appeared on the screen. Initial val-
ues are automatically preset, only when a new EEPROM is used (Judge with the first 4 bytes ).
ii) The initial data are preset as listed in page 4-2 to 7-1.
iii) Make sure the data need modification or not (Initial data).
NOTE: Once the chassis has been assembled together and ready to be POWER ON for the FIRST TIME, make sure to short JA304 & JA307 to
switch to the service mode position first and then turn on the main power switch (See 2-i) above).
Precaution: If haven’t done this initialization, it may possibly generate excessive Beam current.
3. For reference please check with memory map.
