Before Starting Disassembly

Prohibition:
Do not perform disassembly with power supplied. (Perform work with power supply off.)
Execute operation check to be performed after completing attachment/assembly, with all components
reassembled.
This DVD video camera/recorder incorporates a laser emitter block: Never let the laser beam strike your eye.
Essential note:
Take antistatic measures: Wear a wrist strap, etc. to prevent damage to electronic components because of
static electricity in human body.
Cautions:
Lens, loader and mechanism unit are precise components: Do not subject them to impact or undue force.
Do not disassemble the components in lens or drive mechanism unit.
Be careful that no foreign object, such as dust, enters the lens or drive mechanism unit.
Be sure to use only replacement parts listed in "parts list".
1) Press the DISC EJECT button and make sure that the disc loading block opens. If a disc is in the holder, remove it.
(After checking and removing the disc, close the disc loading block.) If the disc loading block does not open, refer to
"3. Troubleshooting during Disassembly" on the next page.
2) Flat-cable connectors (female) used in this DVD video camera/recorder are four types a - d shown in Fig. 2-1:
Note that the disconnection method with flat cable is different for each connector. (Some connectors have the same
structure as type-a, but the flat cable is connected to the circuit board at right angles.)
Connect the flat cables by the reverse procedure to disconnection.
Type-a disconnection
(1) Move both ends of connector in the direction of the arrows (parallel with flat cable) to release the lock.
(2) Pull out the flat cable in the direction of the arrow.
Type-b disconnection
(1) Pull up both ends of connector from the circuit board (in the direction of the arrow) to release the lock.
(2) Pull out the flat cable in the direction of the arrow.
Type-c disconnection
(1) Disconnect the flat cable from connector in the direction of the arrow.
Type-d disconnection
