2-1 Servicing Jigs and Special Tools
2-1-1 Servicing guide
1.For this VCR chassis, the program switch and the sensors (start/end/reel) are located on the main PCB, not on the deck ass’y.
2.As long as the deck ass’y is connected to the main PCB, all repairs are possible.
Important : In order to repair the main PCB without the deck ass’y connected, the X-5 chassis jig should be used.
3.To emulate the function of the sensors, connect a jumper or solder land (two point) at service option(W750) on the function-timer PCB.
2-1-2 Servicing Jig
4. The X-5 chassis jig can be used for the following :
1)When repairing or confirming the operation of the deck ass’y.
2)When replacing or repairing the components located under the deck ass’y.
3)When repairing the function PCB.
5.The X-5 chassis jig can not be used for the following :
1)Repairing defects in the video section.
2)Repairing defects in the audio section.
3)If the defect is related to tape speed.
Note :
1)Repair may not be possible if there is external noise between the deck ass’y and main PCB.
2)If tape control signal is not connected to the jig, the VCR must be operated in SP mode.

Note : After completing repairs, SW715 on the function PCB in order to reset.
4.Insert wafers of drum motor, capstan motor and loading motor on X-5 chassis jig into each of the connectors of deck ass’y, and then secure with three screws.
5.Solder the 3 leads of the jig cable to “CN605” on the main PCB.
6.Apply power to the function PCB.
7.Insert a test tape into the housing ass’y.
8.Simultaneously touch the start and end sensor LEDs on the PCB, so that the tape loads automatically. After the tape is loaded, all of the function buttons on the function PCB can be used.
9.If the test tape is ejected while the jig is in use, attempt to re-load the tape by simultaneously touching the start and end sensor LEDs. If the tape still does not load, reset the function PCB by pressing SW715.
