Use the following procedure to access the Digital Convergence Adjustment Mode (DCAM)

These methods only work if your convergence circuits are working or have been recently repaired! 

If for any reason you can't move the RED and Blue cross hairs in all directions - UP - DOWN - LEFT - RIGHT you need to first repair the convergence before proceeding.   Please check out store for a kit! 


MAGIC FOCUS METHOD DETAILS


To correct abnormal convergence, turn off the television and allow for cool down, approximately 30 seconds. Turn on the television again, and allow for minimum of 20 minutes for warm up. If after pressing MAGIC FOCUS button still returns abnormal convergence, follow the below procedure to access the Digital Convergence Adjustment Mode (DCAM), then first attempt to correct by reading old ROM data into memory. If your TV has a manual convergence section try that first before DCAM.


PROCEDURE FOR DP14G AND DP15 CHASSIS:

Hook up the cables so that your TV displays video. (Set is in Normal mode.) 

1. Press the MAGIC FOCUS button on front panel.

2. While Magic Focus is running, press the MAGIC FOCUS button again to ?STOP?.

3. When ?STOP? is displayed on the OSD, press the RECALL or the STATUS button on the remote control.

4. The unit will now be in the DCAM.

 

GOTO  Adjusting Convergence section below!!!




PROCEDURE FOR HP13 CHASSIS:

(1) Hook up the cables so that your TV displays video. (Set is in Normal mode.) 

1. Press and hold the MAGIC FOCUS button on the front panel.

2. While the button is held down, the OSD will change from ?MAGIC FOCUS? to ?CENTER MODE?,then to ?STATIC MODE?.

3. When ?STATIC MODE? is displayed on the OSD, press the INPUT or the ANT button on the remote control.

4. The unit will now be in the DCAM.

 

GOTO  Adjusting Convergence section below!!! 


Procedure for Chassis DP14G, DP15E, DP15, DP17:

(1) Hook up the cables so that your TV displays video. (Set is in Normal mode.) 

1. Press the MAGIC FOCUS button on front panel.

2. While Magic Focus is running, press MAGIC FOCUS button again to ?stop?.

3. When ?STOP? is displayed in OSD, press RECALL or STATUS button on remote control.

4. The unit will now be in the DCAM.

 

GOTO  Adjusting Convergence section below!!! 



Procedure for Chassis DP06, DP07, HP13:

(1) Hook up the cables so that your TV displays video. (Set is in Normal mode.) 

1. Press and hold the MAGIC FOCUS button on front panel.

2. While the button is held down, the OSD will change from ?MAGIC FOCUS? to ?CENTER MODE?, then to ?STATIC MODE?.

3. When ?STATIC MODE? is displayed in OSD, press INPUT or ANT button on remote control.

4. The unit will now be in the DCAM Mode


Procedure for Chassis DP05F, DP05, HP11, HP12:

(1) Hook up the cables so that your TV displays video. (Set is in Normal mode.) 

1. Press and hold the DIGITAL ARRAY or CONVERGENCE ADJUST button on front panel.

2. While the button is held down, then press the INPUT or ANT button on remote control.

3. The unit will now be in the DCAM.

 

 GOTO  Adjusting Convergence section below!!!


 DCAM Button



If your TV does not have a magic focus feature or if you still can't get into DCAM using the methods described above try this procedure.

One some hitachi TV sets there is a small button located on the front of the convergence board. This is the side that faces the front of the TV. Its very hard to see from the BACK of the TV.


(1) Hook up the cables so that your TV displays video. (Set is in Normal mode.) 

1) Power on the TV.  

IMPORTANT: DO NOT HOLD THE BUTTON DOWN WHILE POWERING ON THE TV! REPEAT - DO NOT  HOLD THE BUTTON DOWN WHILE POWERING ON THE TV. If you do so you will erase all stored data and spend dozens of hours trying to reset convergence. 

2) Remove the front panel of the TV to access the button. With the TV powered on press and hold the button until you see the convergence grid appear. 

Button is on the convergence board facing the front of theTV. 


Remove the front panel/speaker panel - to access the button. Or reach around the TV and press it from the back.  


 

 3. The unit will now be in the DCAM Mode

 

GOTO  Adjusting Convergence section below!!! 


Adjusting Convergence



Now that you are in DCAM you will need to adjust the convergence...

1) First - Lets try to read the original values stored in the TV set.

  • Press the SWAP button twice to read old ROM data into memory.
  • ?READ FROM ROM?? will display on the OSD after the first press of the SWAP button.

2) Proceed with digital convergence adjustments ONLY if READ FROM ROM did not clear up the convergence error.

3) On the screen you will see the convergence grid. The goal is to re-align all the colors behind the each other. Green is the master grid and typicaly should not be adjusted if its straight.  


 



USING THE REMOTE CONTROLL TO ADJUST THE GRID



Now that you ready to adjust the convergence you need to know how to move around the grid. 

Use the following information

Pressing the remote button.... 

“STATUS or Info”  = Selects Green

“0” = Selects  Red

“ANT or Input" =  Selects Blue

Pressing the remote button....  

Use 4, 6, 2, and 5 to move the cursor position (dotted lines).

Pressing the remote button... 

Thumb stick/Arrows  up/down/left/right  = will adjust the lines in that direction.


Three adjustment modes/sizes are available:

(3x3) Press “STATUS” 5 times 

(7x5) Press “0” 5 times

(13x9) Press “ANT” 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 or if you are having a hard time getting the convergence to align try the (3x3) mode again  then repeat (7x5) mode to remove distortion, then return to (13x9) mode to finish touch-up convergence.

To confirm and fine tune the convergence at the edge of the screen, press the PIP CH button on
the remote control while in the digital convergence adjustment mode (DCAM) for additional lines at the edge of the screen. Fine tune the edge convergence as necessary. To exit, press PIP CH again.
 




Example:

Lets adjust the blue color!!!

First - We select the blue color by pressing the "ANT or Input key on the remote"

 

1) Start adjustment at the center of the screen.

2) Cursor over to the next position by pressing either the 4, 6, 2, and 5 to move the cursor position (dotted lines).


(3) Adjust center area first, ending with edge sections. Use the thumbstick/arrows to adjust the blue line in the correct direction. In this case we need to move it up to match the grid! 


(4) Press INFO button to perform calculation operation.


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


5) After interpolation, check convergence again and
repeat (1)-(5) if necessary.


(6) 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.


(7) DATA WRITE TO ROM will take approximately 4
seconds and no picture will be displayed.


(8) Green dots will be displayed when operation is
completed.


(9) Press MUTE to return to convergence pattern, then
confirm again convergence is acceptable.


(10) Press PIP MODE (ROM WRITE) mode, then press
PIP CH to initialize sensor data positions.


 

If you are having a hard time getting them aligned try swithching modes... 

Three adjustment modes are available:

(3x3) Press “STATUS” 5 times 

(7x5) Press “0” 5 times

(13x9) Press “ANT” 5 times



 Saving the new Convergence Settings



Remember to save the correction data. To save the correction data, press the PIP MODE or Move button twice. ?WRITE TO PTV 2 of 2 PTV 01-10 ROM?? will display on the OSD after the first press of the PIP MODE button or Move Button.

After the second press of the PIP MODE button or Move Button, the screen will go dark for approximately 20 seconds. When the data has been saved, or ROM WRITE has been completed, green dots will appear on the OSD corresponding to the 13 x 9 crosshatch intersection adjustment points.

After the green dots appear, press the MUTE button to return to the DCAM.

Note: The above procedure may not work on all models. If that is the case  press the power button on the front of the TV. 


 Magic Foucs Fix


 Magic Focus Initialize - Adjustment Preparation


(1) Hook up the cables so that your TV displays video. (Set is in Normal mode.)
(2) Digital convergence adjustment should have been completed above. 
(3) Set is in DCU adjustment mode.

Adjustment Procedure


(1) Press PIP MODE and then PIP CH to initialize Magic Focus. The initialize operation starts and several windows appear during this operation. It takes about 30 seconds or less.
(2) When green dots appear, initialize operation is finished.
(3) Turn power OFF.


Another way to start the initialize operation:
(1) Press SERVICE ONLY Sw. on CONVER/FOCUS PWB to set DCU adj. mode.
(2) Press [PIP MODE] key on R/C. Then ROM WRITE? is displayed for alarm. Next, press [PIP
CH] key on R/C to start initialization. When green dots appear, initalization operation is finished.


*[PIP MODE]* key is same function as current [MOVE]
key.
