TOUCH-UP ALIGNMENT Green Needs Adjustment
Like Analog convergence, the green is used as the reference color. Green should be touched up only if its out and both red and blue are aligned with each other. Otherwise, theres no way to know if the reference is out or the other two colors are out. (it could happen) When green needs alignment, the overlay should be used to check the reference. Proceed to the Green 13 x 9 Mode (page 85) portion of the complete convergence procedure.

(continued)

Using the CRT magnets (centering rings), align each color as described in the diagrams below. The horizontal line (left/right) for each color should be aligned with the center horizontal line of the overlay. The vertical line (up/down) for each color should be positioned as shown, which is offset. This is done so that the Convergence Output devices (STKs) will operate in a more efficient manner, thus preventing possible memory overload in the DCU and causing an error during sensor initialization. For example, the Blue is offset to the right because the Blue CRT is physically to the right of center (Green).
Single Crosshatch Green Centered

Horizontal / Vertical Size Adjust
After the magnetic centering has been accomplished, the master size adjustment should be checked, and adjusted if necessary. Apply the screen overlay. (page 6) Clear the DCU RAM. (page 74) Select Green Only Press the button on the remote associated with Color Display Mode (Remove Color), then press the button on the remote associated with Green Only / 3 x 3. Example: MENU, RECALL Adjust horizontal and vertical size controls (usually located on the Power/Deflection PWB) so that the raster size corresponds to the size marks on the overlay.

STATIC CENTERING

After the magnetic centering and size adjustments have been verified, the Static Centering should then be adjusted. The screen overlay should be in place, and the DCU RAM should still be cleared. Enter the Static Raster Centering Mode Press the button on the remote associated with Centering. Example: FREEZE Two additional horizontal lines will appear, to indicate that the set is now in the Static Raster Centering Mode.

2H MODEL PROCEDURES

General 2H Model Information Most of the Hitachi 2H (HDTV capable) models require that additional procedures be performed. This is due to the fact that the horizontal or vertical deflection is manipulated in some way, to properly display the input HDTV signal. (An example would be a 4:3 model displaying a 1080i image, which is 16:9) On the older 2H models, (pre-2001) the additional procedure involves simply doing the entire convergence procedure a second time, using a different overlay and engaging the manipulated deflection mode. However, on the newer 2H models, there are other adjustments that need to be performed before even starting the convergence correction procedures, such as DCU Character Set-up, and DCU Pattern Set-up. These additional adjustments are necessary because the same DCU is used in a multitude of cabinet sizes and the light pattern must strike the sensors correctly for Magic Focus to function as well as the correct "wording" must be seen. Understand that as this document is prepared, newer and/or more up to date alignment information can be located on our website, http://www.hitachiserviceusa.com

DP-17 Procedures
The DP-17 has only one deflection mode however, there are two adjustments which must be properly adjusted before starting the convergence correction adjustments; they are DCU PHASE ADJUST and HORIZONTAL POSITION ADJUST. DCU PHASE ADJUST 1. Input an NTSC signal via tuner, composite video, or S-video. 2. Press the Service switch. 3. Press HELP button on remote. (Green crosshatch is displayed) 4. Press EXIT button on remote. (Character pattern is displayed, which is the DCU Phase setting mode) 5. Set PH-H phase data as shown below by using the 4 and 6 button on the remote. 6. Set PH-V phase data as shown below by using the 2 and 5 button on the remote. 7. Set CR-H phase data as shown below by using the ' and ( button on the remote. 8. Set CR-V phase data as shown below by using the " and ! button on the remote. 9. Press HELP button on remote to exit from PHASE ADJUST Mode. 10. Press PIP MODE button on remote twice to write the new Phase data to memory. 11. When Green dots appear, press MUTE button on remote to return to DCU adjustment mode.

DP-26/27/27D Procedures

The DP-26/27/27D has only one deflection mode however, there are two adjustments which must be properly adjusted before starting the convergence correction adjustments; they are DCU PHASE ADJUST and HORIZONTAL POSITION ADJUST. DCU PHASE ADJUST 1. Input an NTSC signal via tuner, composite video, or S-video. 2. Press the Service switch. 3. Press AV NET button on remote. (Green crosshatch is displayed) 4. Press EXIT button on remote. (Character pattern is displayed, which is the DCU Phase setting mode) 5. Set PH-H phase data as shown below by using the 4 and 6 button on the remote. 6. Set PH-V phase data as shown below by using the 2 and 5 button on the remote. 7. Set CR-H phase data as shown below by using the ' and ( button on the remote. 8. Set CR-V phase data as shown below by using the " and ! button on the remote. 9. Press AV NET button on remote to exit from PHASE ADJUST Mode. 10. Press PIP MODE button on remote twice to write the new Phase data to memory. 11. When Green dots appear, press MUTE button on remote to return to DCU adjustment mode.

HORIZONTAL POSITION ADJUST 1. Input an NTSC crosshair signal. 2. Press the Service switch to change to internal DCU crosshatch. 3. Mark the center of the DCU crosshatch with your finger. 4. Enter the I2C Bus alignment menu and select Item H POSITION. 5. Adjust the data so that the center of NTSC crosshair matches the location found in step 3 above. 6. Press the MENU button to exit from the Service Menu. Service Menu access and how to view/change the I2C Data values: The Set should be OFF Press and hold the INPUT (PAGE 01) button on the front panel. ADJUST MODE Then press the POWER SERVICE ! button. ! SUB BRT Release both buttons. ! WHITE BAL The Service Menu (I2C) R DRV (COOL) 3F should appear on the B DRV (COOL) 3F screen. To scroll through the Menu R CUTOFF (COOL) 80 use the " and ! buttons.
