GENERAL
The operating instructions mentioned here are partial abstracts from
the Operating Instruction Manual. The page numbers of the
Operating Instruction Manual remein as in the manual.
1-1. ANTENNA CONNECTION
To connect a VHF antenna or a combination VHF/UHF antenna—
75-ohm Coaxial Cable (Round)
Plug the connector into the T socket of the TV.
To connect the indoor antenna
(Except for KV-1485GET, 1685GET, 1985GET, 2185GET, 1985AS, 2185AS)
We recommend using an outdoor antenna for better reception.
For KV-1405GE or KV-1415AS
KV-1405GE These models do not have audio/video jacks. Use an antenna cable to connect a VTR. (Page 3)
KV-1415AS
KV-1405GE | This model is not supplied with a Remote Commander. Use the buttons on the TV for operation.

SET-UP ADJUSTMENTS
@ The following adjustments should be made when
a complete realignment is required or a new
picture tube is installed.
@ These adjustments should be performed with
rated power supply voltage unless otherwise noted.
The controls and switch should be set as follows unless
otherwise noted :

Preparation:
@ Feed in the white pattern signal.
@ Before starting, degauss the entire screen.
3-1. BEAM LANDING
1. Input a raster signal with the pattern generator.
2. Loosen the deflection yoke mounting screw, and
set the purity control to the center as shown in
Fig.2
3. Turn the raster signal of the pattern generator
to green.
4. Move the deflection yoke backward, and adjust
with the purity control so that green is in the
center and red and blue are at the sides evenly.
(Fig.3)
5. Move the deflection yoke forward, and adjust so
that the entire screen becomes green. (Fig.1)
6. Switch over the raster signal to red and blue and
confirm the condition. |
7. When the position of the deflection yoke is
determined, tighten it with the deflection yoke
mounting screw.
8. When landing at the corner is not right, adjust
by using the disk magnets. (Fig.4)

Preparation:
@ Before starting, perform FOCUS, H.SIZE, V.LIN
and V.SIZE adjustments.
@ Set BRIGHTNESS control to minimum.
@ Feed in dot pattern.
(1) Horizontal and Vertical Static Convergence
1. Adjust H.STAT VR to converge red, green and blue
dots the in center of the screen.(Horizontal move-
ment)
2. Adjust V. STAT magnet to converge red, green and
blue dots in the center of the screen. (Vertical move-
ment)
3. If the red, green and blue dots do not converge on
the center of screen with H.STAT VR, perform
horizon-tal convergence adjustment using H.STAT
VR and V.STAT magnet as shown below. (In this
case, H.STAT VR and V.STAT magnet effect each
other.)
