2-1-4 How to Connect X-5 chassis jig
4. Insert wafers of drum motor, capstan motor and
loading motor on X-5 chassis jig into each of the
connectors of deck ass’y, and then secure with
three screws.
5. Solder the 3 leads of the jig cable to “CN608”
on the main PCB.
6. Apply power to the function PCB.
7. Insert a test tape into the housing ass’y.
8. Simultaneously touch the start and end sensor
LEDs on the PCB, so that the tape loads
automatically. After the tape is loaded, all of the
function buttons on the function PCB can be
used.
9. If the test tape is ejected while the jig is in use,
attempt to re-load the tape by simultaneously
touching the start and end sensor LEDs. If the tape
still does not load, turn power off in order to reset.
Note : After completing repairs, turn power off in order to reset.
1. Unplug the power cord from AC outlet.
2. Remove the deck ass’y from main PCB (See Page
4-5 of service manual).
3. To emulate the function of the sensors, place a
jumper or solder land (two point) at service
option(W750) on the timer PCB. Be sure not to
operate function key within 6 seconds.
