Setting Definitions
APRTR: Aperture Setting
Reduces significant ringing observed around letters and edges. Note that the last number/letter 3=ANTa/b, G=480i/p, I=1080i. - Last
number/letters on my set were different; I just found the 3 APRTRT parameters and change all 3 to 00.

COLORG: Color gamma correction point
- Red push fix… Tames the reds a bit and definitely softens out skin tones making them appear more natural.

SRTGA: Super Real Transient Gain
- Has been mentioned to improve detail and sharpness.

Regular Video Settings
– Standard user menu using Menu button, not when in Service Menu.

CONTRAST = 25% to 41%                                                   TINT = 0 to -3 (3 Clicks left of center)
BRIGHTNESS = 45% to 63%                                                 COLOR TEMP = STD
COLOR = 45% to 50%                                                      SHARP = 25 to 50

If settings are too dark for you during the day, you can use them in the Night mode, and tweak the Contrast and Brightness up in the
Day mode. You can even then set the TV's clock, and have it switch the modes automatically.

| If you are using the CLU-4361S remote, there are no PIP Channel buttons, use:
| STOP        = FINE GRID, or, in use with ASPECT, performs INITIALIZE for Magic Focus.
| NOTE: The RASTER mode allows you to center the entire grid for the color you
| have selected. You cannot perform any other adjustments when in RASTER mode.
| NOTE: If you start from the center, just hit the channel DOWN button to move to the next
| alignment point. This should provide the proper ‘working to the outside’ steps.


DCAM Convergence How To
To utilize the 7x5 adjust (which you should do 1st to avoid S curves) you need to select "0" on the remote 5 times.
To utilize 13x9 adjust you need to select "input" on the remote 5 times.

Start in the "medium" 5 x 7 grid first. Get the convergence good then go to the 9 x 13. If you start in the 9 x 13, you can waste an hour
getting it almost perfect and then have an "S" curve happen on one of the last few points, so you have to go to the "medium"
adjustment just to fix it... and then redo much of the 9 x 13.

Work from the center out.

Walkthrough
    1.   Put on Input you will be adjusting and make sure you are receiving a signal.
    2.   Enter DCAM Mode:
         Use the blue Service Button method or
              a. Press and Hold TV key on remote then press ASPECT, then 9 keys. (puts remote in LINE ADJUST mode)
              b. Press STOP key (bottom of remote, has black square on it) to enter DYNAMIC ADJUST mode.
              c. Change Remote to DCU mode: TV + MENU + INFO
              d. In DCAM mode you will see the service grid, red is the selected color by default and it is flashing.
    3.   Start from the center of the screen and work your way out on one color at a time. I adjusted red across the whole screen to
         match green. Then I switched to blue, and adjusted that to green as well. After you adjust blue, you may want to go back and
         adjust some red again? etc. until the convergence looks good.
              a. Use 4, 6, 2, and 5 on the R/C to move the cursor position (dotted lines).
              b. Use thumb stick to move the convergence point color.
              c. There have been other posts in here to tape together the color filters found in the Avia DVD to help converge lines
                   more easily. I have used this method, and it works well for adjusting to a greater detail. Basically, you put the red filter
                   next to the green and adjust your red to the green line both horizontally, and then vertically. Then you do the same
                   with the blue next to the green. Some people recommended you should be at normal viewing distance. I did mine
                   from just a few feet back from the set. There are some other posts also recommending using binoculars. I think it’s
                   great that people suggest things to make the process easier. Whatever you feel works best!
    4.   I did not adjust the green at all. I use the green as the guide and did not adjust the location of any green point. This is highly
         suggested unless you have geometry problems.
              a. To choose other colors to converge, use the following buttons on the remote:
                      INFO or STATUS = Green
                      0 = Red
                      INPUTS or ANT = Blue
    5.   When going along the lines and adjusting, you may run into the problem of getting an "S" curve on the line. You’ll know if you
         get there, you’ll see the lines curve. Basically, no matter what you do to adjust the line to be converged, the middle of the line
         between the points will not straighten out (it bends between the points). To fix this, the manual recommends going to the (7x5)
         mode which gives you less points to adjust. I had this problem, and the solution worked. There is also another mode (3x3)
         which gives you even less points. Basically, if the set looks good, you only fine tune it in (13x9) mode. If you have serious
         problems, the grids work as:



                                    Version 01/06/2007 2:35:00 PM08:20AM Page 2 of 6
                               Hitachi xxF59 DIY Service Guide
                 3x3 - "coarse"
                 7x5 - "medium"
                 13x9 - "fine"
    6. To get to each of these patterns use the following on the remote (press each button 5 times) :
                 INFO or STATUS = (3x3) -- only works when DCU is in uncorrected state
                 0 = (7x5)
                 INPUTS or ANT = (13x9)
        Note: The grid size doesn't change, but the cursor "skips" a line.
    7. If you adjust the 3x3, then you should go to the 7x5, and then the 13x9. You get the point? Depending on where you start,
        work your way up, and always finish on the 13x9
    8. When finishing up the 13x9 mode, to get a fine grid to work with, press the PIP CH (Pip Channel) button on the remote. Fine
        tune the edge convergence as necessary. To exit the fine grid, press PIP CH again.
    9. When convergence is acceptable, press PIP MODE or ASPECT to write data to ROM memory. The words “ROM WRITE?” are
        displayed to alarm system that ROM will be overwritten with new data. Press the PIP MODE or ASPECT button again to write
        displayed data to ROM.
    10. DATA WRITE TO ROM will take approximately 4 seconds and no picture will be displayed.
    11. Green dots will be displayed when operation is completed.

WARNING: YOU MUST DO THE FOLLOWING STEPS TO COMPLETE MAGIC FOCUS INITIALIZATION. THERE HAVE BEEN
MANY POSTS THAT PEOPLE HAVE HAD PROBLEMS WITHOUT DOING THIS STEP BECAUSE THEY LOOSE MAGIC FOCUS!

    12. Press MUTE to return to convergence pattern, now confirm convergence is acceptable.
    13. Press PIP MODE or ASPECT and then PIP CH to initialize Magic Focus. The initialize operation starts and several windows
        appear during this operation. It takes about 30 seconds.
    14. When green dots appear, initialize operation is finished.
    15. Press the blue button to exit DCAM mode
    16. Turn power OFF using remote key sequence of TV - 0 - 1
    17. Wait a few seconds. Turn the TV on, and you should have your normal signal. Press Magic Focus button just to make sure the
        magic focus still works (and that you did the last few steps properly)

NOTES…

While in the DCAM press "MENU" displays only the green grid.

If you push 0, or ANT you can display Red or Blue on top of the green. This allows you to converge Red into Green and then Blue into
Green respectively.

If you push "MENU" repeatedly it scrolls through various DCAM options. One of which allows the user to view an NTSC source as the
background to the DCAM grid. This would then allow the user to set the geometry perfectly from a pattern generated say from your
DVD player.

| NOTES from Service Manual:
| (1) Display only green for easier adjustment and match to jig screen. Press “MENU”, THEN PRESS “INFO”.
| (2) Perform interpolation (calculation) 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 DAY/NIGHT 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.
| (6) To confirm and fine tune the convergence at the edge of the screen, press      the button on the
| remote control while in DCAM for additional lines at the edge of the screen. Fine tune the edge
| convergence as necessary. To exit fine tune, press        again.

For newer Hitachi, models like the S T500 with different remotes...

Taken from the T500 service manual:
Assuming you're already in the DCAM mode. Follow this exactly and you will reinitialize your magic focus to your new setting.
T and S models are pretty much the same with some added feature.

    1.  Adjustment procedure
    2.  Receive any NTSC signal.
    3.  Start adjustment at the center of the screen.
    4.  Continue adjustment at next closest position.
    5.  Adjust center area first, ending with edge sections. -Press VID3 button to perform calculation operation. This process will take
        about 1 second and no picture will be seen at this time.
    6. After interpolation, check convergence again and repeat steps 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.
    11. Press PIP MODE (ROM WRITE) mode, then press SURF to initialize sensor data positions.

         Adjusting Color and Tint using RGBOUT

         Bring up the color bars of your choice (I've used AVIA and DVE with the same results).
         In the user menu, set Color to 50, Tint to 0 and Temperature to Standard.
         In the service menu, change COLORG to 00 (if you've changed it to 01).
         Change RGBOUT (first item in TA1360 menu) to 03.
         Scroll down to COLOR-STD and TINT-STD and alternate between them until the blue boxes are all the same color.
         Don't forget to press SELECT to save your final settings.
         Back up to RGBOUT, change to 02 (green).
         Alternate between GY-PH-CBCR and G/BGA-CBCR-STD to get as many of the green boxes as close to the same
         color as possible.         Back to RGBOUT, change to 01 (red).
         Alternate between RY-PH-CBCR and R/BGA-CBCR-STD to get as many of the red boxes as close to the same
         color as possible.         Up to RGBOUT, change to 00 (unless you're particularly fond of red, green, or blue). SELECT.
         Find COLORG and change it back to 01. SELECT.
         Exit the service menu, pop in the disc of your choice, and let me know what you think.


        When viewing using the blue primary only, the white, blue, cyan, and magenta colors will form four vertical blue bars that
should be the same intensity from the top to the bottom of the display.

          When viewing with the red filter or CRT beam, the red, white, yellow and magenta colors should all appear as the same
intensity of red.

         When viewing with the green filter or green CRT beam, the green, white, yellow and cyan colors should appear to be the
         intensity as of green.
