CONVERGENCE ADJUSTMENT
Notes: In the convergence mode, if the first two displayed characters are "P", it means PAL, and if "Q", it means NTSC. In the two modes of DVD, the character display is the same as the two above-mentioned modes. "V" stands for VGA mode. These characters are omitted in the following OSD display description.
CONVERGENCE
ADJUSTMENT IN PAL
With
receiving of PAL signal, and the volume to 0, press and hold MUTE button until
the red "MUTE" character becomes three colors (or white), then press
MENU button on front panel of TV to enter "S" mode (Press
"S" button on the jig to enter "S" mode directly when in
production). Press yellow RECALL button to enter the phase of convergence adjustment,
and the red convergence crosshatch displays in the screen. Press DISPLAY button
to switch into green crosshatch signal.
Note"
Generally speaking, you can go to Step IV, V, VI and VII directly.
Press
TEXT button to clear fine/coarse adjusted data of the six channels in the RAM
of convergence IC.
Note:
Normally speaking, do not reset the RPTV to0. If it is necessary, exit
convergence mode and time it before your resetting.
Adjustment
of static convergence in green. Press PIP button until the video image
super-imposes crosshatch-testing signal. Press PICTURE MODE SELECTION button
until character "DCGH" appears, then press POSITION UP/DOWN buttons
to call up "DCGH"( DCGV). Press VOLUME UP/DOWN buttons to make the
center of green line (field) of 5-CH video test pattern locate at the center of
the screen. Then press PIP button to conceal the video image.
Phase adjustment
Adjustment of H. fine adjustment and phase of horizontal test
Instate of crosshatch in green, press PICTURE MODE SELECTION button to call up " FINE NODE", and press SWAP button to switch the cursor into green. Press MUTE button until "P LOCK" appears. Now press POSITION UP button to display the GV value of fine adjusted convergence at H#4/V#4 point as the maximum value on the screen.
Press AV button to call up "FINE PHASE", Press VOLUME UP/DOWN buttons to make the peak appear at the vertical line at the right of horizontal center.
Press AV button to call up "TEST PHASE". Adjust VOLUME UP/DOWN button to make the cursor locate at the peak.
Reset GV value.
Setting of start lines of fine-adjusted convergence (setting of STARTLINES)
In the state of crosshatch in green, press PICTURE MODE SELECTION button to enter "FINE MODE", then press VOLUME UP/DOWN buttons to set the GH fine adjustment value at H#4/V#4 as maximum, and make the peak displays on the screen.
Press AV button to call up "STARTLINES", then press VOLUME UP/DOWN buttons till the peak displays at the center of the field. (Note: "START LINES" value can only be odd number).
Return the GH fine adjusted value.
Press
PICTURE MODE SELECTION button to display "DCRH". Press POSITION UP/
DOWN buttons to call up "KGV3", and press VOLUME DOWN button to set
KGV3 as a larger data. If the cursor is off the horizontal center, press AV
button to call up "COAR PHASE", then press VOLUME UP/DOWN buttons to
return the cursor to the original position.
Press
PICTURE MODE SELECTION button until "DCRH" displays on the screen.
Press POSITION UP/DOWN buttons to call up "KGH3", and adjust VOLUME
UP/DOWN but-tons to set "KGH3" as a larger data. If the cursor is off
the field center, press AV button to call up "START VALUE", then
press VOLUME UP/DOWN buttons to return the cursor to the original position.
"COUNTUP"
Setting
Press
and hold AV button till "COUNTUP" appears, and press VOLUME UP/DOWN
buttons to make crosshatch signal basically be straight in the V/H
direction.
(The recommended COUNTUP data: PAL 3D, and NTSC 3D.
Coarse-adjustment
of convergence in green
Press
PICTURE MODE SELECTION button till "DCRH" appears, then press
POSITION UP/DOWN buttons to select coarse adjustment order as follows:
Trim
horizontal skew in green (KGH3).
Trim
green horizontal pincushion distortion (KGH1)
Trim
green horizontal amplitude (KGH2).
Trim
green field pincushion distortion (KGV2).
Trim
field keystone distortion (KGV1).
Trim
green field skew (KGV3).
Fine-adjustment
of convergence in green
Press
PICTURE MODE SELECTION button to call up "FINE MODE", press SWAP but
line to turn the cursor into green. Press DIGIT SELECTION button to select the
point or line adjustment. Press MUTE button to move or fix the cursor: (When
OSD is "POINT MOVE" or "LINE MOVE", press VOLUME UP/DOWN or
POSITION.UP/DOWN buttons to move the cursor up, down, left and right. When OSD
is "POINT LOCK" or "LINE LOCK", press VOLUME UP/DOWN or
POSITION UP/DOWN buttons to adjust the dot or line data).
Notes:
• In the process of fine adjustment, the cursor
will change into 3 colors automatically. Press MUTE button after adjusting a data,
the cursor will return to original color.
• It is recommended to perform trimming fine
errors from the center of the screen toward out-side area in circumference
inaccordance with such an order as whirlpool-shape. In other word, at first,
trim fine error at the point of H#4/V#4 of the screen center, next trim each
fine point in circumference around outside of the 8 points, then trim other
points in the same way.
• If adjusting one point to increase fine error
of nearby ones, which are not adjusted, you should adjust the data at your
target point to make the error of nearby ones in the permissible range.
Otherwise the fine adjustment data of nearby point might not meet the
requirement even if the data reaches maximum.
• You can save the adjusted data by pressing
MENU button. When OSD displays "DATA OK", the data is saving, and
when " DATA OK" disappears, it indicates the saving is complete.
• When adjusting the parameters of coarse and
fine adjustment in green, it will activate the convergence of the other two
guns at the same time.
Adjustment
of convergence in red
In
convergence mode, press DISPLAY button to switch crosshatch state into red and
green.
Adjustment
of static convergence in red, adjust "DCRH" and "DCRV" of
coarse adjustment convergence, so that superimpose the center of line-field in
red with center of line-field in green.
Trim
horizontal skew in red (KRH2)
Trim
horizontal linearity distortion in red (KRH1)
Trim
horizontal amplitude in red (KRH3)
Trim
field keystone in red (KRV1)
Trim
field skew in red (KRV2)
Adjusting
procedures of fine adjustment data in red is the same as that in green, but
crosshatch on the screen is yellow.
Adjustment
of convergence in blue
In
convergence state, press DISPLAY button so that crosshatches in red and blue
appear on the screen, and press PIP button to make the cursor become blue.
Adjustment
of static convergence in blue. Press and hold PICTURE NODE SELECTION button
until "DCBH" appears, Press POSITION UP/DOWN buttons to call up
"DCBH" and "DCBV", and press VOLUME UP/ DOWN buttons to
position the line-field center of convergence in blue at the center of screen.
Trim
horizontal skew in blue (KBH2),
Trim
horizontal linearity distortion in blue (KBH1).
Trim
horizontal amplitude in blue (KBH3).
Trim
field keystone in blue (KBVI).
Trim
field skew in blue (KBV2).
Saving
Press MENU button to save the adjusted data.
Press STILL/MOVABLE PICTURE ADJUSTMENT button to copy the adjusted data to the corresponding mode of DVD.
CONVERGENCE ADJUSTMENT IN OTHER MODES
Repeat the above-mentioned procedures for NTSC and VGA.
CONVERGENCE ADJUSTMENT IN DVD MODE
In DVD mode, it requires fine trimming PAL and NTSC.
