ALIGNMENT PROCEDURES
Operating Conditions
Unless otherwise noted, the following conditions must be
observed when aligning the TV:
1. Chassis must be operated from a 120 VAC isolation transformer with line voltage set to 120 VAC.
2. All voltages and waveforms referenced are with respect
to Ground
3. A 10X probe must be used for oscilloscope and frequency
measurements.
TV Service Screen
The service screen is provided to facilitate instrument alignment and service adjustments. The service screen is accessed
by pressing a two-button combination on the front control
panel of the instrument.
Using the Front Panel Controls to enter Service Screen
1. Turn on the TV and select the channel that will be used
for the alignment procedure.
2. With the instrument “ON” press and hold the “Menu”
button and then the “CH q” button.
3. Press the “OK” button on the Remote or Front Panel to
display the service screen Menu as shown.
Fig. 1 Service Screen
Entering the Service Alingment Mode
1. Bring up the Service Screen.
2. Once in the service screen use “CH q” button on the keyboard or the down arrow on the remote control to highlight item “2 Service Alignment”.
3. Press “Menu” on the keyboard or “OK” on the remote
control to activate the Alignment Screen.
Fig. 2 Service Alignment Selection
4. Once the Alingment Screen has been activated use the
“VOLu” button on the keyboard or remote to adjust the
value (V:0) to the desired value.
Fig. 3 Service Alignment Screen
NOTE: When the service mode is accessed, the parameter
will be “0”. Parameter “0” is used to input the security code.
The security code is necessary to protect the factory alignments from inadvertent modification. Attempting to change
the parameter (P) using “CHq” or “CHp” before the proper
security code has been entered will cause the instrument to
exit the service mode. A valid security code is entered (using
“VOLt”or “VOLu”).
Security Codes
When the Service Alignment Screen is first entered, the parameter (P) will come up set at “0”, which corresponds to the
security code function.
1. With the parameter (P) set to “0” adjust the value (V)
(using “VOLt”or “VOLu”) to “76” for access to the
Electrical Alignments.
2. Once the security code has been set, individual alignments can be accessed by pressing “CHq” or “CHp”
changing the parameter (P) number.
ATC336
ALIGNMENT PROCEDURES
3. Once a parameter (P) has been selected for a particular
alignment the “VOLt“and “VOLu” buttons can be
used to change the value (V) of the alignments selected.
Most Electrical adjustments for the DLP instrument must
be done using Chipper Check.

Warranty Clock
1. Enter the TV Service Mode. Highlight item 2 Service
Alignment. Press “OK” on Remote Control.
2. Using the Volume Buttons, go to V: 90. Press “Channel
Up”. The display will show the number of hours in use,
along with the number of hours plugged in. Press the
“Power” button to exit.
Error Codes
If certain failures occur in the chassis, error codes will be
stored in the chassis EEprom. These error codes can be accessed by entering the service menu and setting the VALUE
to 50. With the VALUE set to 50, pressing the Channel up
button will toggle through the 6 error codes. Error code “0”
stores the error code for the first failure experienced by the
instrument. Similarly, error code “1” stores the error code
for the second failure. Error code “2” stores the error code
for the third failure. Error code “3” displays the error code
for the most recent failure experienced by the instrument. Information is displayed in the following order: Error #, Date,
Time, Type, Count, Code. If an Error of the same TYPE is
Error # Date Time Type Count Code
0: 0.0.0 0:0:0 Type=21 Count=4 Code = 4002010000000000
Fig. 4 Error Code Screen
already logged, then the error will overwrite the existing error of that type and the count will be increased. Error codes
are summarized in Fig. 5.
The presence of “Empty” for the error code indicates that
no failures have occurred since the time the error codes were
reset. The error codes can (and should) be reset to “0” after
servicing. Press the clear button to clear the error code that
is currently being displayed.
1. Enter the Service Menu.
2. Press Volume Up Until V is 50.
3. Press Channel Up to View The First Error.
4. Press Channel Up/Down to View the Next/Previous Error.
5. Press Clear to Clear the Error Code that is Currently
Being Displayed.
6. Press Power Off to Return to the P:0 V:50 Display.
7. Press Power Off Again to Return to Normal TV Viewing.
To use the Error Code charts, first look up the “Type”
displayed in the error code (Fig. 4). Then find the Type
number (Hex) in the first error code chart (Fig. 5). The description column indicates the general area of the problem
and the Detail column gives additional information for some
Error Codes.
If the Error Code “Type” is 21 or 22, additional information is available as shown in Fig. 6. Refer to the last string
of hex characters referred to as Data or Code in Fig. 4. The
first two characters hex value of the string refer to the “Chip”
information in Fig. 4. The second two characters hex value
in the string refer to the “Bus” information in Fig. 4. The
third two characters hex value in the string refer to the “Details” information in Fig. 4.
If the Error Code “Type” is 41, additional information is
available as shown in Fig. 5. Refer to the last string of hex
characters referred to as Data or Code in Fig. 2. The first
two
characters hex value refer to the “Watchdog” information in
Fig. 5.

Alignment
Picture centering and rotation are controlled by mechani
cally aligning the position of the DMD module onto the
Light Engine. Prior to alignment, the engine must first be
fully installed into the instrument. Use the following
procedure for centering and rotation alignments. For DMD
Module screw locations see the graphic on the next page.
1. To define the true center of the screen, mark the
projection screen with crosshairs in the center with
0 degrees rotation.
2. Apply a border pattern with cross hair or an appropriate
test pattern.
3. Loosen the three (3) T10 Torx Head DMD Module
mounting screws.
4. Grip the two (2) tabs and adjust the X-Y centering and
rotation of the DMD Mount.
5. Tighten the DMD Module screws when the alignment is
complete.
NOTE: DO NOT loosen the two (2) custom DMD mount-
ing screws.
