*IMPORTANT

For many of the above adjustments, it is necessary to have an HDTV (1080i) signal generator, SDTV (480P) sig­nal generator, as well as the usual NTSC (480i) signal generator.
Hitachi recognizes that few companies offer HDTV or SDTV signal generators and that the cost of these genera­tors is sometimes prohibitive. For this reason, we suggest the use of a set-top-box for HDTV and SDTV adjust­ments. Usually, there is a switch on the set-top-box which enables it to output HDTV (1080i) or SDTV (480P) sig­nals even with no input. In this case, the sync is automatically detected by the TV (at the Y-P

BPR

Inputs on the

rear panel).

appear after clearing RAM data,
press service switch again (on
POWER/DEFLECTION PWB).

(3) To restore old RAM data, turn TV

Note: If only minor adjustments to convergence are

needed, the jig screen is not necessary. Use
digital data stored in memory and one color as a
reference (red, green, or blue). DO NOT CLEAR
DATAand WRITE to ROM memory.

Adjustment preparation
(1) Position adjustment - This will move an entire

color. Use this adjustment to match colors at the
center of the screen. (Active video center from
external signal and physical screen center
should now match from phase adj. 2.2.).

(2) Use the buttons below to switch color to adjust.

“RECALL” - Green
“0” - Red
“INPUT” - Blue

Adjustment procedure
(1) Press the FREEZE button. Extra horizontal lines

appear to confirm raster position mode.
(2) Use the thumb stick to adjust position.
(3) Press FREEZE again to exit raster position

mode.

Notes: (1) Other functions cannot be accessed when

in raster position adjustment mode. Press
FREEZE and confirm extra horizontal lines
disappear to exit raster position mode.

(2) Press MENU to switch between all colors

displayed or adjustment color and Green
only.

6#&6#6 0"CSFGVFCRF E"JCD HOgLKDMFCD

Adjustment preparation
(1) Select color to adjust.

“RECALL” - Green

“0” - Red

“INPUT” - Blue
(2) Use 4, 6, 2, and 5 to move the cursor position

(dotted lines).
(3) Use thumb stick to move the convergence point.
(4) Three adjustment modes are available:

1. (3x3) Press “RECALL” 5 times (only works
when DCU is in uncorrected state)

2. (7x5) Press “0” 5 times

3. (13x9) Press “INPUT” 5 times

For touch-up, only the (13x9) mode is necessary.
This will adjust every cross-hatch intersection point
on the screen.

For complete adjustment, start with (3x3) mode. This
will adjust center point and eight edge points only,
but will greatly reduce adjustment time. Then use
(7x5) mode, and finally (13x9) mode to finish
convergence.

If “S” distortion appears between cross-hatch lines
repeat (7x5) mode to change calculation process
while adjusting to remove distortion, then return to
(13x9) mode to finish touch-up convergence.

Adjustment procedure

(1) Receive any NTSC signal.
(2) Start adjustment at the center of the screen.
(3) Continue adjustment at next closest position.
(4) Adjust center area first, ending with edge

sections.

(5) Press INFO button to perform calculation

operation. This process will take about 2
seconds and no picture will be seen at this time.

(6) After interpolation, check convergence again

and repeat (1)-(5) if necessary.

(7) When convergence is acceptable, press PIP

MODE to write data to ROM memory. ROM
WRITE? is displayed to alarm system that ROM
will be overwritten with new data. Press the PIP
MODE button again to write displayed data to
ROM.

(8) DATA WRITE TO ROM will take approximately 4

seconds and no picture will be displayed.

(9) Green dots will be displayed when operation is

completed.

(10) Press MUTE to return to convergence pattern,

then confirm again convergence is acceptable.

Adjustment procedure

(1) Receive any HD signal.
(2) Repeat steps 2~11 above.

Notes: (1) Display only green for easier adjustment

and match to jig screen. Press “MENU”,
THEN PRESS “RECALL”.

(2) Perform interpolation and data write to ROM

after green adjustment. Once green has
been confirmed to match jig screen, the jig
screen can be removed. Do not readjust the
green color after jig screen has been
removed. This is now your reference color.

(3) Display green and red only and match red to

green.

(4) Display all colors and match blue to green

and red. Touch-up red color if necessary.

(5) Existing DATA in ROM can be read by

pressing the SWAP button 2 times. This
data can be used after replacing a
component (CRT, DY, etc.) Where complete
convergence adjustment is not necessary
be careful not to overwrite this data.
DO NOT write cleared RAM data into ROM
or a complete convergence adjustment will
be necessary.
