PRECAUTIONS IN REASSEMBLING
MOUNTING THE CASSETTE CONTROLLER
Initial setting is indispensable
made in two ways; electrical and mechanical.
Electrical setting:
Make a short-circuit between TP8804 and TP8805, both located at the center on your side on VCR PWB,
with a 22 ohm resistor and be sure that the mechanism is back to its initial setting position (*l). Now place
the cassette controller in position. (This method is used when the mechanism has been already set on its
COUPLING THE MECHANISM TO THE PWB
Match the mechanism's projections with the two symbols (round reference and oval sub-reference) on the
VCR PWB. Place the mechanism straight down in position with due care so that the mechanism chassis's
outer edges should not damage any parts nearby.
Tighten up the two screws (one for fixing the mechanism and the head amplifier shield, the other on the
VCR PWB's soldering side and located near the loading motor) to fix the mechanism and VCR PWB.
Reconnect the FFC cables (EB, EF and EH) and harnesses (ED and EG) between the mechanism and VCR
