Servicing Hints; Service Tools - Philips CD210 Service Manual

SERVICING HINTS
In the set chip components have been applied.
For disassembly and assembly of chip components see
the figure below.
The disc should always rest properly on the turntable.
To achieve this a disc hold-down has been mounted in a
bracket of the tray mechanism.
if the tray mechanism has to be disassembled for
servicing, a separate disc hold-down should be used. For
a service disc hold—down see drawing 42565 A12.

Test discs
It is important to treat the test discs with great care. The
disorders on the discs (black spots, fingerprints, etc.) are
exclusive and unambiguously positioned. Damage may
cause additional drop-outs etc. rendering the intentional
errors no longer exclusive. In that case it will no longer
be possible to check e.g. the good working of the track
detectors.
