SAFETY & PRECAUTIONS SAFETY CHECK AFTER SERVING Examine the area surrounding the repaired location for damage or deterioration. Observe that screw, parts and wires have been returned to original positions. Afterwards, perform the following tests and con- form the specified values in order to verify compliance with safety standards. 1. - Page 4 SAFETY & PRECAUTIONS 4. Leakage current test Confirm specified or lower leakage current between B(earth ground, power cord plug prongs) and externally exposed accessible parts (RF terminals, antenna termi- nals, video and audio input output terminals, microphone jacks, earphone jacks, etc.) Measuring method:(Power ON) Insert load Z between B(earth ground, power cord plug prongs) and exposed accessible parts.

Page 15: Circuit Operation
CIRCUIT OPERATION 1. VIDEO PART 1-1) EE MODE Video Signal which is output from RL902 is input to pin 37 of IC301 through OSD IC. It is amplified 6dB by AGC, then it is output to pin 34. This output signal is output to Video Jack through RL902 of RELAY IC. 1-2) REC MODE The signal which is input to pin 37 of IC301 is output to pin 3 through IC internal AGC AMP. - Page 16 CIRCUIT OPERATION 1-3) PB MODE When playing the tape, the signal which is picked up from the tape is amplified 60 dB. Then luminance signal goes to pin 11 and color signal goes to pin 7 through AGC. Luminance signal of pin 11 is input to pin 39 of IC301 through PB EQ circuit in order to match playback characteristic.
- Page 17 CIRCUIT OPERATION 2. AUDIO PART 2-1) EE MODE External AUDIO signal which is input to pin 16 of IC201 is output from pin 22 of IC201 after being ampli- fied through ALC and Line Amp. 2-2) REC MODE It will be the REC mode when REC 5V is input to pin 24 of IC201. Input signal will be replaced on the tape through R/P HEAD after being amplified and modulated with Bias Frequency.
