REMOVAL 1. Put the Masking Tape (cotton tape) around the Flat Package IC to protect other parts from any damage. (Refer to Fig. 4-1.) NOTE Masking is carried out on all the parts located within 10 mm distance from IC leads.
Blower type IC desoldering machine

3. When IC starts moving back and forth easily after desoldering completely, pickup the corner of the IC using a tweezers and remove the IC by moving with the IC desoldering machine. (Refer to Fig. 4-3.) NOTE Some ICs on the PCB are affixed with glue, so be careful not to break or damage the foil of each IC leads or solder lands under the IC when removing it.

INSTALLATION 1. 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. 4-5.) 4. When bridge-soldering between terminals and/or the soldering amount are not enough, resolder using a Thintip Soldering Iron. (Refer to Fig. 4-8.)

Thin-tip Soldering Iron

Confirm that no abnormality is found on the soldering position and installation position of the parts around the IC. If some abnormality is found, correct by resoldering. NOTE When the IC leads are bent during soldering and/or repairing, do not repair the bending of leads. If the bending of leads are repaired, the pattern may be damaged. So, be always sure to replace the IC in this case.

2. CONFIRMATION AND ADJUSTMENT OF TAPE RUNNING MECHANISM
Tape Running Mechanism is adjusted precisely at the factory. Adjustment is not necessary as usual. When you replace the parts of the tape running mechanism because of long term usage or failure, the confirmation and adjustment are necessary. 2-1: GUIDE ROLLER 1. Playback the VHS Alignment Tape (JG001 or JG001B). (Refer to SERVICING FIXTURE AND TOOLS) 2. Connect CH-1 of the oscilloscope to TP101 (Envelope) and CH-2 to TP3002 (SW Pulse). 3. Press and hold the ATR button on the remote control more than 2 seconds to set tracking to center. 4. Trigger with SW Pulse and observe the envelope. (Refer to Fig. 2-1-A) 5. When observing the envelope, adjust the Adjusting Driver (JG005) slightly until the envelope will be flat. Even if you press the Tracking Button, adjust so that flatness is not moved so much. 6. Adjust so that the A : B ratio is better than 3 : 2 as shown in Fig. 2-1-B, even if you press the Tracking Button to move the envelope (The envelope waveform will begin to decrease when you press the Tracking Button). 7. Adjust the PG shifter during playback. (Refer to the ELECTRICAL ADJUSTMENTS) NOTE After adjustment, confirm and adjust A/C head. (Refer to item 2-2)
