ELECTRICAL ADJUSTMENT

Method of Using the Jig Remote Controller
Most of the video circuit and the deflection circuit of this set can be adjusted by using the jig remote controller.
Jig remote controller: RC-AVC01
The jig remote controller RC-AVC01 has the two operating modes. One is the NORMAL mode and the other is the TEST mode.
Either the NORMAL mode or the TEST mode can be selected by short-circuiting or opening the shorting land of the printed foil
pattern.
The TEST mode of the jig remote controller is used for adjusting this set.
The NORMAL mode and the TEST mode are selected as described below.
NORMAL/TEST mode selection method:
Disassemble the jig remote controller and locate the shorting land J1 and J2 on the foil pattern of the printed circuit board.
When the remote controller enters the TEST mode, its REPEAT key becomes the TEST key and the CAPTION key becomes the
FINISH key. All keys other than the above two keys are disabled so that the remote controller will not operate even if any key other
than those two keys is pressed.
When the word the TEST key or the FINISH key is written in this Service Manual, it means that the REPEAT key must be
pressed instead of the TEST key, and the CAPTION key must be pressed instead of the FINISH key respectively on the
actual jig remote controller.
NORMAL mode:
J1 Shorted
J2 Open
TEST mode:
J1 Open
J2 Shorted
