SECTION 1 PRECAUTION
1.1 SAFTY PRECAUTIONS Consequently, when servicing these products, replace the cathode ray tubes and other parts with only the specified parts. Under no circumstances attempt to modify these circuits.Unauthorized modification can increase the high voltage value and cause X-ray emission from the cathode ray tube. (12) Crimp type wire connectorIn such cases as when replacing the power transformer in sets where the connections between the power cord and power trans former primary lead wires are performed using crimp type connectors, if replacing the connectors is unavoidable, in order to prevent safety hazards, perform carefully and precisely according to the following steps. Connector part number :E03830-001 Required tool : Connector crimping tool of the proper type which will not damage insulated parts. Replacement procedure a) Remove the old connector by cutting the wires at a point close to the connector.Important : Do not reuse a connector (discard it). Prior to shipment from the factory, JVC products are strictly inspected to conform with the recognized product safety and electrical codes of the countries in which they are to be sold.However,in order to maintain such compliance, it is equally important to implement the following precautions when a set is being serviced. 1.1.1 Precautions during Servicing (1) Locations requiring special caution are denoted by labels and inscriptions on the cabinet, chassis and certain parts of the product.When performing service, be sure to read and comply with these and other cautionary notices appearing in the operation and service manuals. (2) Parts identified by the symbol and shaded ( ) parts are critical for safety. Replace only with specified part numbers. NOTE : Parts in this category also include those specified to comply with X-ray emission standards for products using cathode ray tubes and those specified for compliance with various regulations regarding spurious radiation emission. (3) Fuse replacement caution notice. Caution for continued protection against fire hazard. Replace only with same type and rated fuse(s) as specified. (4) Use specified internal wiring. Note especially: Wires covered with PVC tubing Double insulated wires High voltage leads (5) Use specified insulating materials for hazardous live parts. Note especially: Insulation Tape PVC tubing Spacers Insulation sheets for transistors Barrier (6) When replacing AC primary side components (transformers, power cords, noise blocking capacitors, etc.) wrap ends of wires securely about the terminals before soldering.

Fig.2-1a 2.2 Jig RCU mode This unit uses the following two modes for receiving remote control codes. (1) User RCU mode:Ordinary mode for use by the user. (2) Jig RCU mode: Mode for use in production and servicing. When using the Jig RCU, it is required to set the VCR to the Jig RCU mode (the mode in which codes from the Jig RCU can be received). As both of the above two modes are stored in the EEPROM, it is required to set the VCR back to the User RCU mode each time that an adjustment is made or to check that the necessary operations have been completed.These modes can be set by the operations described below. Note: When the unit is set to JIG mode and when the unit is under JIG mode, the remote control unit attached to product operates only in "Remote Control Code 1". Since the unit is in "Remote Control Code 3" when it is shipped and just after its batteries are changed, "Remote Control Code 3" needs to be changed to "Remote Control Code 1." Confirm the RCU mode when exchanged parts. Since some SERVICE PARTS sets the VCR to the Jig RCU mode as initial setting. Therefore please set the VCR to the user RCU mode after replacing the EEPROM.

2.2.1 Changing Remote Control Code (1) Slide the TV/CABLE/DBS/DVD switch to DVD. (2) Press the numeric button "1" of the remote control unit while pressing the "SET UP" button of the remote control unit. Then,press the "ENTER" button, and then release the "SET UP" button. (3) Press the "POWER" button on the unit to turn off the unit. (4) Press the "PLAY" button on the unit for over 5 seconds while the unit is turned off. The code currently set appears on the front display panel. (5) Press the "STOP" button on the remote control to change the units code. When FDP indicator displays "DVD1," it means that the Remote Control Code has been changed to "1." 2.2.2 Setting the Jig RCU mode (1) Turn on the power. (2) Press the VCR/DVD button repeatedly on the unit so that the VCR lamp lights up on the unit. (3) Press the following remocon keys continuously within 2 seconds " SET UP " " 2 " " 8 " " ENTER ". When the VCR is set to the Jig RCU mode, the symbols ( " : " ) in the time display of the FDP are blinked. (Refer to Fig.2-2a User/Jig RCU mode) 2.2.3 Setting the User RCU mode (1) Turn off the power. (2) Press the "REC" and "PAUSE" buttons of the VCR simultaneously. Alternatively, transmit the code "9D" from the Jig RCU. 2.3 Mechanism service mode This model has a unique function to enter the mechanism into every operation mode without loading of any cassette tape. This function is called the "Mechanism service mode". 2.3.1 How to set the "Mechanism service mode" (1) Set the VCR to the Jig RCU mode (the mode in which codes from the Jig RCU can be received) (2) Transmit the code "E5" from the Jig RCU. (3) Release the lug of the Cassette holder and then slide the Cassette holder toward the direction where the Cassette holder is loaded by manually. (4) The cassette holder lowers and, when the loading has completed, the mechanism enters the desired mode. When the VCR is set to the Mechanism service mode, the symbols ("HDD") in the FDP (LED) are turned on. 2.3.2 How to exit from the "Mechanism service mode" (1) Unplug the power cord plug from the power outlet. 2.4 Maintenance and inspection 2.4.1 Cleaning Regular cleaning of the transport system parts is desirable but practically impossible. So make it a rule to carry out cleaning of the tape transport system whenever the machine is serviced. When the video head, tape guide and/or brush get soiled, the playback picture may appear inferior or at worst disappear, resulting in possible tape damage. Note: Absolutely avoid sweeping the upper drum vertically as this will cause damage to the video head. (1) When cleaning the upper drum (especially the video head), soak a piece of closely woven cloth with alcohol and while holding the cloth onto the upper drum by the fingers, turn the upper drum counterclockwise.

4.1.6 Manual tracking mode (Auto tracking ON/OFF) setting (1) In order to set to the manual tracking mode during tape playback, press the SP/EP(LP)button on the remote control unit. Each press of the button switches the auto tracking ON or OFF. When the manual tracking mode is set, the tracking is placed at the center position. (2) Press channel +/- to adjust the tracking manually. 4.1.7 EVR Adjustment Some of the electrical adjustments require the adjustment performed by the EVR system. The main unit have EEPROMs for storing the EVR adjustment data and user setups. Notes: In the EVR adjustment mode, the value is varied with the channel buttons (+, -). The adjusted data is stored when the setting mode changes (from PB to STOP, when the tape speed is changed, etc.). Take care to identify the current mode of each adjustment item when making an adjustment. When changing the address setting in the EVR adjustment mode, use the Jig RCU or the remote controller having numeric keypad with which a numeric code can be directly input. The remote control code of the Jig RCU corresponds to each of the digit keys on the remote controller as follows.

As the counter indication and remaining tape indication are not displayed FDP during the EVR adjustment mode, check them on the TV monitor screen. When performing the EVR adjustment, confirm that the FDP indication is changed to the EVR mode. 4.2 Mechanism compatibility adjustment (VHS SECTION) Notes: Although compatibility adjustment is very important, it is not necessary to perform this as part of the normal servicing work. It will be required when you have replaced the A/C head, drum assembly or any part of the tape transport system. To prevent damaging the alignment tape in the compatibility adjustment, prepare a cassette tape (for self-recording/playback), perform a test on it by transporting it and making sure that the tape is not bent by the tape transport mechanisms such as in the guide rollers.(See Fig.4-2b.) 4.2.1 Tension pole position Notes: This adjustment must be performed every time the tension band is replaced.

(1) Play back the back tension cassette gauge (A). (2) Check that the indicated value on the left side gauge is within the specified value (G). (3) If the indicated value is not within the specified value (G), perform the adjustment in a following procedure.(See Fig.4-2a.) a) Remove the top frame, cassette holder and side frames (L/R) all together. (Refer to the SERVICE MANUAL No.86700 [MECHANISM ASSEMBLY].) b) Rotate the loading motor gear to move the control plate so that the triangular stamping to the left of the Pstamping is aligned with the stamping (a) on the main deck. This positioning is mode (B1). c) Adjust by turning the adjustment pin so that the tip of the tension arm is aligned with the stamping (b) on the main deck. d) Rotate the reel disk (S) by about one turn clockwise and make sure that the round hole of the adjustment pin is located in the OK range. If it is outside this range, restart the adjustment from the beginning. After completion of the adjustment, rotate the loading gear motor to return it to the mode (B2) position.
(1) Play back the alignment tape (A1). (2) Apply the external trigger signal to D.FF (E), to observe the V.PB FM waveform at the measuring point (D). (3) Set the VCR to the manual tracking mode. (4) Make sure that there is no significant level drop of the V.PB FM waveform caused by the tracking operation, with its generally parallel and linear variation ensured. Perform the following adjustments when required. (See Fig. 4-2c.) (5) Reduce the V.PB FM waveform by the tracking operation. If a drop in level is found on the left side, turn the guide roller of the pole base assembly (supply side) with the roller driver to make the V.PB FM waveform linear. If a drop in level is on the right side, likewise turn the guide roller of the pole base assembly (take-up side) with the roller driver to make it linear. (See Fig. 4-2c.) (6) Make sure that the V.PB FM waveform varies in parallel and linearly with the tracking operation again. When required, perform fine-adjustment of the guide roller of the pole base assembly (supply or take-up side). (7) Unload the cassette tape once, play back the alignment tape (A1) again and confirm the V.PB FM waveform. (8) After adjustment, confirm that the tape wrinkling does not occur at the roller upper or lower limits. (See Fig. 4-2b.) [Perform adjustment step (9) only for the models equipped with SP mode and EP (or LP) mode.] [Perform adjustment step (9) only for the models equipped with SP mode and EP (or LP) mode.] (9) Repeat steps (1) to (8) by using the alignment tape (A2).

5.3.4 EMG content description Note: EMG contents E09 are for the model with Dynamic Drum (DD).

E01: Loading EMG

CONTENT
If the mechanism mode does not change to the next mode within 4 seconds after the loading motor starts rotating in the loading direction, while the mechanism is in the after-loading position (with the tape up against the pole base), [E:01] is identified and the power is switched OFF. However, if the tape loading is not completed within 4 seconds after the loading motor starts rotating in the loading direction, the tape is simply unloaded and ejected. No EMG data is recorded in this case. When the mechanism mode cannot be changed to another mode even when the loading motor has rotated for more than 4 seconds in the unloading direction, [E:02] is identified and the power is turned off.
1. The mechanism is locked in the middle of the mode transition during a tape loading operation. 2. The mechanism overruns during the tape loading operation because the SYSCON cannot recognize the mechanism mode normally. This problem is due to a cause such as a rotary encoder failure. 3. Power is not supplied to the loading MDA. (M12V/Vcc/Vref/ICP are disconnected in the middle.)
