[TechAssist] Re: Hitachi Mod: 51F500 Magic focus

Hey Ben ,sounds like the last tech forgot to
initialize the magic focus after servicing as per the
digital focus written down below. Here is that info
along with more info on magic focus and convergence.

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 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 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

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.
