Thanks Tiberio, but I have read all of that. Seems that info is everywhere,
even on the NET for anyone to get. It is not specific to my model. The
problem with all of that is that even though it list my model 50DX10B at the
very end of the thread, it talks about Magic Focus. And then it only tells
how to enter the Digital Convergence Adjustment Mode (DCAM), without opening
the front of the unit to access the service switch. My set 50DX10B does not
have Magic Focus, it has a Digital Array button instead. The sets with
Digital Array work differently, at least the convergence save part. I know
someone has had to come across this button and had to do a convergence
alignment. At least I thought maybe since the set came out in 2001. I still
don't have a answer in case someone can help.

here are some notes
SUBJECT: MAGIC FOCUS METHOD DETAILS

Magic focus

MODEL: 43UWX10B DP-14G CHASSIS
53UWX10B, 53UWX10BA DP-14G CHASSIS
61UWX10B, 61UWX10BA DP-14G CHASSIS
53UDX10B, 53UDX10BA DP-15 CHASSIS
61UDX10B DP-15 CHASSIS
53SBX10B HP-13 CHASSIS
SUBJECT: MAGIC FOCUS METHOD
DETAILS:
Some of the new 2001 Projection TV models are using
?Magic-S? convergence technology instead of the prior single cross-hatch
technology. This new ?Magic-S?technology uses four sensors instead of eight.
When the MAGIC FOCUS button on the front panel is pressed, the television
will automatically adjust itself to the factory
adjusted data.
NOTE:
BEFORE INITIATING MAGIC FOCUS, THE TELEVISION MUST BE TURNED ?ON? AND HEAT
RUN FOR A MINIMUM OF 20 MINUTES. IF THE MAGIC FOCUS BUTTON IS PRESSED BEFORE
THE WARM-UP PERIOD IS COMPLET, THE CONVERGENCE RESULTS MAY BE ABNORMAL. 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 onvergence, 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 this fails, proceed with digital
convergence adjustments.
PROCEDURE FOR DP14G AND DP15 CHASSIS:
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.
5. 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.
6. Proceed with digital convergence adjustments ONLY
if READ FROM ROM did not clear up the convergence error.
7. Remember to save the correction data and initialize the MAGIC FOCUS
sensors.
To save the correction data, press the PIP MODE 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.
After the second press of the PIP MODE 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. To initialize the Magic Focus
sensors, first press the PIP MODE button once. Again, ?WRITE TO ROM?? will
display on the OSD. Then
press the PIP CH button to start the sensor data position initialization
procedure. When this process has completed, you will again see the green
dots on the OSD, unless an error has occurred in the initialization
procedure, in which case the technician would be presented with an error
code in the lower left corner in the OSD corresponding to what the actual
error is. Failure to initialize MAGIC FOCUS sensors after saving convergence
correction data will result in a STATIC (+) display when MAGIC FOCUS
attempts to run. The technician will then be required to access the service
only switch behind the
front cover to get back into the DCAM to initialize
the sensors, since the procedure to access DCAM without removing the front
panel, requires MAGIC FOCUS to be running.
8. To exit, press the POWER button on the front panel.

PROCEDURE FOR HP13 CHASSIS:
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.
5. 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.
6. Proceed with digital convergence adjustments ONLY if READ FROM ROM did
not clear up convergence error.
7. Remember to save the correction data and initialize
the MAGIC FOCUS sensors. To save the correction data, press the PIP MODE
button twice. ?WRITE TO ROM??will display on the OSD after the first press
of the PIP MODE button. After the second press of the PIP MODE 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. To initialize the Magic Focus sensors, first press the
PIP MODE button once.
Again, ?WRITE TO ROM?? will display on the OSD. Then press the PIP CH button
to start the sensor data position initialization procedure. When this
process has completed, you will again see the green dots on the OSD, unless
an error has occurred in the initialization procedure, in which case the
technician would be presented with an error code in the lower left corner in
the OSD corresponding to what the actual error is. Failure to initialize
MAGIC FOCUS sensors after saving convergence correction data will result in
a STATIC (+) display when MAGIC
FOCUS attempts to run.
8. To exit, press the POWER button on the front panel.

SUBJECT: DIGITAL CONVERGENCE ADJUSTMENT MODE ACCESS
Details:
In the past, when the technician needed to enter the
Digital Convergence Adjustment Mode (DCAM),
it was necessary to open the front of the unit to
access the service switch. Now, to access the DCAM
without removing the front panel, please follow the
below instructions.
Procedure for Chassis DP14G, DP15E, DP15, DP17:
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.
Procedure for Chassis DP06, DP07, HP13:
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.
Procedure for Chassis DP05F, DP05, HP11, HP12:
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.
NOTE:
1. Proceed with digital convergence adjustment.
2. Remember to save the correction data.
3. Units with MAGIC FOCUS only - Failure to initialize
MAGIC FOCUS sensors after saving
convergence correction data will result in a STATIC
(+) display when MAGIC FOCUS attempts
to run. The technician will then be required to access
the service only switch behind the front
cover to get back into the DCAM to initialize the
sensors, since the procedure to access DCAM
without removing the front panel, requires MAGIC FOCUS
to be running.
4. To exit, press the POWER button on the front panel.
5. There is NO remote access code for DP15E Chassis.
