1. REMOVAL OF ANODE CAP Read the following NOTED items before starting work. After turning the power off there might still be a potential voltage that is very dangerous. When removing the Anode Cap, make sure to discharge the Anode Cap's potential voltage.
REMOVAL AND INSTALLATION OF FLAT PACKAGE IC REMOVAL Put the Masking Tape (cotton tape) around the Flat Package IC to protect other parts from any damage. (Refer to Fig. 2-1.) NOTE Masking is carried out on all the parts located within 10 mm distance from IC leads.
Page 11
INSTALLATION Take care of the polarity of new IC and then install the new IC fitting on the printed circuit pattern. Then solder each lead on the diagonal positions of IC temporarily. (Refer to Fig. 2-5.) Soldering Iron Solder temporarily Supply the solder from the upper position of IC leads sliding to the lower position of the IC leads.
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. Set Key Remocon Key VOL. (-) MIN VOL.
WHEN REPLACING EEPROM (MEMORY) IC If a service repair is undertaken where it has been required to change the MEMORY IC, the following steps should be taken to ensure correct data settings while making reference to TABLE 1. Enter DATA SET mode by setting VOLUME to minimum. While holding down VOLUME button on front cabinet, press key 6 on remote control for more than 2 seconds.
BEFORE MAKING ELECTRICAL ADJUSTMENTS Read and perform these adjustments when repairing the circuits or replacing electrical parts or PCB assemblies. CAUTION • Use an isolation transformer when performing any service on this chassis. • Before removing the anode cap, discharge electricity because it contains high voltage.
