This set is a component of the MHC-S90D.
The MHC-S90D system configuration is as shown below, and
therefore it does not operate normally unless all four components
are connected.
In performing the repair, connect all components with the system
cables.
Note: The precaution to the users is described on the label stuck
on the back panel (DVD/video CD/CD player) and in the trouble-
shooting section in the Operation Manual.

TCM-230AWR41 and TCM-230MWR41 are used for the tape
mechanism deck of this set, and they can be discriminated as shown
below.
