Tape Deck; Drive Assembly - Philips VR120 Service Manual

10. Tape deck

10.1 Drive assembly

This tape deck has three motors; one providing precision
drive for the scanner unit; the second providing direct drive
for the capstan and belt drive for the reel tables; the third
motor drives the lift and tape threading/dethreading
operations.
Special features are:
– Quick start
– Short winding time
– Automatic cleaning of video heads by cleaning roller
To obtain a high repair standard we have developped a
range of service kit's. These kit's covers the spare parts
which are engaged together.
The tape deck's sensors are located on the motherboard
underneath the tape deck, and included in its circuitry, lay out
and parts list.
10.1.1 Deck parts replacement
The procedure for the removal and refitting of the following
parts is described; only the lift, the scanner, the capstan
motor and the A/C head are fixed by screws.
All the other deck assembly parts are held only by snap
hooks.
For the replacement of parts on the underside of the tape
deck, remove the tape deck from the motherboard.
Manual extraction of cassette:
If, after the Eject button has been pressed, the drive does not
unthread and eject the cassette, the dethreading/eject
operation can also be carried out manually by turning the
wheel at the rear of the threading motor.

IMPORTANT:
After each repair has been carried out in the drive assembly,
the first operation after repairing must be to bring the
cassette compartment into „eject" position by hand.
