Confirm that the oscilloscope waveform S-curve is symmetrical between A and B. And confirm peak to peak level within 2 0. S-curve waveform symmetry. Measure voltage between pin 22 and pin 3 of IC Adjust T11 ubtil the voltage becomes 0 V. After check, remove the lead wire connected in step 2.
Note : Try to measure several times to make sure than the ratio of A : B or B : A is more than 10 : 7. Take sweep time as long as possible and light up the brightness to obtain best waveform. Turned Power switch on. Load a disc LUV-P01 and playback. Confirm that oscilloscope waveform is clear and check RF signal level is correct or not.
Note: Clear RF signal waveform means that the shape can be clearly distinguished at the center of the waveform. Load a disc LUV-P01 and playback the number nine track. Press the bB button. Becomes the 1track jump mode. Confirm that the level B and A DC voltage on the oscilloscope waveform. In addition to this, the necessary note is printed in each block. Note on Schematic Diagram: All capacitors are in F unless otherwise noted.
C : panel designation. Note: The components identified by mark 0 or dotted line with mark 0 are critical for safety.
Replace only with part number specified. Note: Les composants identifis par une marque 0 sont critiques pour la scurit.
Ne les remplacer que par une pice portant le numro spcifi. B : B Line. H : adjustment for repair. Voltages and waveforms are dc with respect to ground under no-signal detuned conditions. Voltage variations may be noted due to normal production tolerances.
Waveforms are taken with a oscilloscope. Circled numbers refer to waveforms. Signal path. Indication of transistor. C These are omitted. See page 54, 55 for IC Block Diagrams. See page 47 for IC Pin Function. See page 55 for IC Block Diagrams. See page 49 for IC Pin Function. See page 52 for IC Pin Function. See page 51 for IC Pin Function. Some delay should be anticipated when ordering these items. The mechanical parts with no reference number in the exploded views are not supplied.
Hardware mark list and accessories and packing materials are given in the last of this parts list. The components identified by mark 0 or dotted line with mark 0 are critical for safety. Les composants identifis par une marque 0 sont critiques pour la scurit. Note: Two different types of tape mechanism are used depending on models.
They maintain compatibility as an entire mechanism even though there are some different parts are used. NOTE: Ref. Part No. Description Due to standardization, replacements in the parts list may be different from the parts specified in the diagrams or the components used on the set. When indicating parts by reference number, please include the board name.
