Unplug the connector CP351, CP757 and CP302, then remove the TV/VCR Block from the set.
Unplug the connector CP810, CP820 and CP850, then remove the Main PCB from the VCR Block.
Connect as shown in the below figure using the Service Fixture.
• Connect the Syscon PCB to the Main PCB with the cable JG162C and JG162D.
• Connect the Syscon PCB to the CRT PCB with the cable JG162Y.
Remove the Operation PCB from the set, then connect it with the Syscon PCB.
If necessary, connect CP351. (Front A/V Jack Input Terminal)
Short circuit between TP1001 and GND with the cable JG154.
(The EOT, BOT and Reel Sensor do not work at this moment.)
At that time, the STOP/EJECT button is available to insert and eject the Cassette Tape.
