Service Mode List
This unit provided with the following SERVICE MODES so you can repair, examine and adjust easily. To enter the Service Mode, press both set key and remote control key for more than 2 seconds. Table 1 Using the SET + or - keys on the remote, step through the ADDRESS until required ADDRESS to be changed is reached. 5. Press ENTER to select DATA. When DATA is selected, it will "blink". 6. Again, step through the DATA using SET + or - until required DATA value has been selected. 7. Pressing ENTER will take you back to ADDRESS for further selection if necessary. 8. Repeat steps 4 to 7 until all data has been checked. 9. When satisfied correct DATA has been entered, turn POWER off (return to STANDBY MODE) to finish DATA input. The unit will now have the correct DATA for the new MEMORY IC. 1. BEFORE MAKING ELECTRICAL ADJUSTMENTS CAUTION Read and perform these adjustments when repairing the circuits or replacing electrical parts or PCB assemblies. Use an isolation transformer when performing any service on this chassis. Before removing the anode cap, discharge electricity because it contains high voltage. When removing a PCB or related component, after unfastening or changing a wire, be sure to put the wire back in its original position. Inferior silicon grease can damage IC's and transistors. When replacing IC's and transistors, use only specified silicon grease (YG6260M). Remove all old silicon before applying new silicon. 1-1: Prepare the following measurement tools for electrical adjustments. 1. Synchro Scope 2. Digital Voltmeter 3. AFT Oscillator 39.5 MHz 4.
