Sharp Aquos 70″HD TV Installation

This week, I was commissioned to install a new HD TV. The client wanted it mounted to the wall and it was requested that no cabling be visible. image

First we laid out the location of the new tv on the wall with masking tape.

We then installed new hardware to mount the tv and to accomodate wire runs and a surge suppressing outlet.

Nakamichi MR1 Cassette Deck Maintenance

Nakamichi MR1Occasionally, a piece of control room equipment needs to be decommissioned and taken into the workshop for service.  This time it was the Nakamichi MR1 Cassette Deck. This deck uses three motors to handle the tape.  These motors depend on each other for proper operation and if one malfunctions, the whole machine stops working.  In this case, the spooling motor had a dead spot and the machine would stop playback to keep the transport from eating the tape.
