IMPORTANT SERVICE NOTES Service Manual TV E Market 29S-FX10M [1] IMPORTANT SERVICE NOTE IMPORTANT SERVICE NOTES Maintenance and repairing of this receiver should be done by qualified service personnel only. 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. 2. 3. 4. Picture tube in this receiver employs integral implosion protection. Replace with the same type number of picture tube for continued safety. Do not lift picture tube by the neck. 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, please make sure do not increase the high voltage of the set to more then 30kV (at beam 0 A). 2. To keep the set in a normal operation, please make sure it's function at 26.0kV 1.5kV (at beam 1700 A). 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 repaires, 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 excessive 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-metal control knobs, insulating fishpapers, cabinet backs, adjustment and compartment covers or shields, isolation resistor- capacity networks, mechanical insulators etc. 2 3 Setting the service mode by the microprocessor. (3) Make sure the data need modification or not (Initial data). (2) The initial data are preset as listed in page 6~10. (1) During POWER OFF (AC OFF), switch on service key (by connecting MCU Pin 5 to ground ) after raster appeared on the screen. Initial values are automatically preset, only when then follow by AC ON. Initial values are automatically preset only when a new EEPROM is used. (Judge with the first 4 bytes ). Factory Presetting. 3. For reference please check with memory map (See Attachment) Precaution: If haven't done this initialization, it may possibly generate excessive Beam current. 2. (6) Press the SERVICE key again, it will switch to the NORMAL mode position, and the microprocessor is out of the SERVICE mode. (5) In Check mode the data cannot be changed. (4) 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. (3) Press the CH DOWN / UP key on the remote controller to select the item in Adjustment mode, Setting mode or Option mode. (2) 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. (1) Press SERVICE key on the remote controller to set the TV set to SERVICE mode position, and the microprocessor is in input mode. (Adjustment through the I2C bus control). Service Mode also can be reached by by connecting MCU Pin 5 to ground. 1. CAUTION : MAKE SURE TV SET IN "NORMAL CONDITION" BEFORE SWITCH TO SERVICE MODE FOR ADJUSTMENT. 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.
