IMPORTANT SERVICE NOTES
Maintenance and repairing of this receiver should be done by quali- fied service personnel only. SERVICE OF HIGH VOLTAGE SYSTEM AND PIC- TURETUBE
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.
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 34.5kV(at
beam 0
µ
A) for the set.
2. To keep the set in a normal operation , be sure to make it function on 30.5kV
±
1.5kV(at
beam 1800
µ
A) 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 repairing,
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.
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- ca- pacity networks, mechanical insulators etc.

ADJUSTMENT PRECAUTIONS Entering service mode (Method 1) 1. Send the service R/C code to enter the service mode. 2. Send it again to exit the service mode. (Method 2) 1. Short the jumper to enter the service mode. Connect "J 311" with "J 403". 2. Stop shorting the jumper to exit the service mode. Service mode menu 1. Select item by ch up/down ,push vol up/down. 2.When you adjust geometry, please set Full mode by "Wide mode key". 3.About geometry adjustment, it is necessary to adjust 2 pattern. »50hz interlace signal »60hz interlace signal About "ResetTV-set" 1.When replacing the flash ROM or EEPROM, the TV may need to be reset. 2. Unless necessary, do not reset the TV because the adjustment data will be initialized. 3.To reset the TV, enter the "Reset TV-set" menu and press the SURROUND key. After about 30 seconds, the NVM data will be initialized. Changing the NVM data 1. Enter the "NVM Edit" menu. 2. Input the addr. and data in hex with the number keys or vol up/down key. »NVM-edit addr. (hex) ---- »NVM-edit data (hex) --
