Procedures To Adjust 3Dγ; Memory - Sony VPL-FX50 Manual

3-8-4. Procedures to adjust 3Dγ
1. To begin with, enter [GAMMA].
2. Set the LEVEL to 1.
3. Observe how the grade of uniformity of the screen
may be and check undesirable portion.
4. Finding possibly un-uniformity, locate the cursor using
and changing [POSISION] as 1, 2, and 3 back and
forth to the place where to adjust uniformity.
5. Moving [R] and [B] up and down, achieve its unifor-
mity to the extent of satisfactory.
6. Repeat adjustments alike on the LEVEL 2 through 6 as
well.
7. Again, observe each the test pattern of the LEVEL 1
through 6.
Finished completely by now, return to the menu 1
layer back " DEVICE ADJUST " .Then save data in
the " SAVE TO MEMORY ".
Notes:
1. Do not adjust for GREEN, but RED and BLUE only.
2. Do not adjust for 0 and 7.
3. Should such adjustments be hardly unavailable and
therefore, want to abandon it to Factory adjust, put the
power source "OFF" before SAVE TO MEMORY of
saving data. Data will return to the value default; the
Factory data.
If, oppositely, should enter to execute SAVE TO
MEMORY, data will not return to the default, unable
Factory to adjust.
Therefore, when saving data after any adjusting
performances, take full care of observation on the
screen.
4. When a case is zoom lens, uniformity is somewhat
dependent to the zooming position. Furthermore, it is
possibly influenced by F Number of the lens.
Due to these reasons, suggest adjustments be done
under the projector system same as the usual operating
conditions.
5. Do not use the menu DEVICE ADJUST for any items
other than 3Dγ Adjust.
This DEVICE ADJUST item is comprised of parame-
ters important to operation of a device. Troubles such
that no picture appears, or the picture clashes will be
produced.
Moreover, data of the DEVICE ADJUST item is
unable to be reset in the factory.
If " SAVE TO MEMORY " should be executed, data
will completely changed to otherwise. Never take
redundant operation to change data.

3-9. Memory

FX50 is composed of the following six Memory blocks.
1. Set memory.
2. Status memory.
3. Channel memory.
4. Chroma memory.
5. W/B memory.
6. Installation memory.
Gamma memory is realized in the gamma mode added by
OFF SET function of the Contrast / Brightness output
value to each device.
For your reference, data stream will be briefed as the
follows.
When plugged in first (Standby state), whole data in the
ROM are written in the NVM (Non volatile memory).
Turning Power ON, memory data required enough for
current video image are selected from each Memory block
and developed in the RAM where adjusting is performed.
Thus, data adjusted in the RAM are written and memorized
in the NVM, automatically when in the user mode, or
triggered by memory operation ( Item in Service / Special
Service ).
W / B and Device Adjust is adjusted by an user in the
Service mode or in the Special Service mode and memo-
rized in NVM at performing memory operation. In this
moment any data adjusted in the factory will be lost.
