Hi-Fi Component SERVICE MANUAL MODEL DN-780R STEREO CASSETTE TAPE DECK Some illustrations using in this service manual are slightly different from the actual set.
DN-780R SAFETY PRECAUTIONS The following check should be performed for the continued protection of the customer and service technician. LEAKAGE CURRENT CHECK Before returning the unit to the customer, make sure you make either (1) a leakage current check or (2) a line to chassis resistance check. If the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of the power cord is less than 460 kohms, the unit is defective.

DN-780R ADJUSTMENT ADJUSTING AND CHECKING THE MECHANISM SECTION 1. Replacing Pinch Roller Before replacing the pinch roller, clean the tape contact surface of the pinch roller and the capstan shaft. Most causes of poor tape transport can be traced to dirty pinch roller and capstan shaft. Capstan shaft Pinch roller Removing the pinch roller Remove the clips that press the pinch roller and pull the pinch roller forward remove it.
DN-780R 5. Checking the Take-up Torque Load the cassette type torque meter FWD side ......... SONY TW2111A REV side .......... SONY TW2121A Check to make sure that the average torque meter reading is within 30 ~ 70g-cm during playback. If it is not within this range, check the voltage (approx. 4V) of the reel motor. After the verification, replace the reel motor if there is no problem with the voltage value. 6. Checking the FF and REW Torques Load the cassette type torque meter (SONY TW2231).
DN-780R 3. Checking and Adjusting the Tape Speed (1) Connect the frequency counter to the LINE OUT terminal and load test tape (SONY TY-224). (2) Load cassette tapes on both cassette decks A and B. Next, on the deck (A or B) whose speed is to be , and adjusted, while holding down the , buttons of deck A together, press the POWER switch.
DN-780R 5. Recording System Adjustment REC Amp 5-1. Adjusting recording/playback comprehensive frequency characteristics. (1) Load a test tape TDK AC-514. Record with a -20 dB 1 kHz input level signal into the LINE IN terminal and playback. (2) Make a sample recording using a 12 kHz input signal and playback this recording. Adjust (left channel) and (right channel) so that they conform to the following specified characteristics. LINE IN ATT PB Amp LINE OUT V.
DN-780R MECHANISM OPERATING TIME CHECK The total operating time of the mechanism is registered in this unit. Check and refer to it when replacing the mechanism, head, or motor. 1. Displaying the Operating Time (1) Set the power to on while pressing the “STOP ( )”, “RESET”, and “MEMO” buttons of the Deck A together. (2) The and buttons of the Deck A are used to switch the display for the Deck A mechanism or for the Deck B mechanism. Ex.
