TO ENTER SERVICE MODE
  • The Service Alignment Mode (SAM) is used to align the set and/or adjust the option settings and to display/clear the error code buffer values.
Entering Service Alignment Mode
  • To enter the Service Alignment Mode (SAM), press the following key sequence on the remote control transmitter: {0-6-2-5-9-6-INDEX or Status.}
  • Do not allow the display to time out between entries while keying the sequence
  • It is also possible to enter the Service Alignment Mode by pressing the“VOLUME +” and “VOLUME -” key on the local keyboard simultaneously for at least 4 seconds when the set is in SDM.
  • To exit the Service Alignment Mode, press the Power button.
In SAM the following information is displayed on the screen:
ITEMS EXPLANATION
Operation Hours (Run Timer):
This display indicates the accumulated total of operational hours. (Shown in hexadecimal format).
Software identification of the main micro controller.(A101US1-2.06)
  • A10 is the engineering chassis name for the A10 PTV chassis
  • 1US1 is a character combination to indicate the software type and the supported languages: 3AP1 or 3AP2 are also possible in the Asian Pacific Region.
  • US = United States, AP = Asia Pacific
  • 1 = Main Software language version number
  • 2.06 = sub-version number.
Error buffer (7 errors possible):
Displays the 7 most recent errors. The most recent error is displayed at the upper left.
Option bytes (8 codes possible):
Summary of options is explained below.
Sub menus are listed in a scroll menu.
SAM MENU CONTROL
  • Menu items may be selected using the cursor ▲/▼ keys.
  • The selected item will be highlighted.
  • When not all menu items will fit on the screen, pressing the cursor ▲/▼ keys on the remote transmitter will display the next/previous menu items.
With the cursor ◄/► keys, it is possible to:
  • (de)activate the selected menu item (e.g. GEOMETRY)
  • change the value of the selected menu item ( e.g. VERSLOPE )
  • activate the selected submenu (e.g. SERV-BLK).
NORMAL USER MENU ACCESS
  • Pressing the “MENU” button on the remote control switches between the SAM and the normal user menus (with the SAM mode still active in the background). 
  • Pressing the “MENU” key in a sub-menu will return the screen to the previous menu.
ERROR CODE BUFFER & ERROR CODES
The error code buffer contains all errors detected since the last time the buffer was erased. The buffer is written from left to right. When an error occurs that is not yet in the error code buffer, the error code will appear at the left side and all other errors shift one position to the right.
The error code buffer will be cleared in the following cases:
  • By activating CLEAR ERRORS in SAM menu
  • Exiting SDM or SAM with the “Standby" command on the remote control
  • Upon automatic reset when content has not changed for 50 consecutive hours.
By leaving SDM or SAM via the power switch, the error buffer will not be reset.
Examples:
ERROR: 0 0 0 0 0 0 0 :No errors detected
ERROR: 6 0 0 0 0 0 0 :Error code 6 is the last and only detected error
ERROR: 9 6 0 0 0 0 0 :Error code 6 was first detected and error code 9 is the last detected (newest) error
The contents of the error buffer can also be displayed by use of the “blinking LED” procedure, if no picture is available.
ERROR CODE DEFINITION
   In case of non-intermittent faults, clear the error buffer before starting the repair; to make sure “old” error codes are not present. If possible check the entire content of the error buffers. In some situations an error code is only the result of another error code (and not the actual cause).
Note: a fault in the protection detection circuitry can also lead to a protection.
   Error codes 1,2, 3, and 4 are protection codes, and in this case the supplies of some circuits will be switched off. Also in protection, the LED will blink the number of times equivalent to the most recent error code.
ERROR CODE TABLE
CLICK ON TABLES TO ZOOM IN
A10 PTV-MODEL LISTING & SOFTWARE
LED BLINKING PROCEDURE & CODES
The contents of the error buffer can also be made visible through the “blinking LED” procedure. This is especially useful when there is no picture.
  • When the SDM is entered, the LED will blink the number of times equal to the value of the error code.
  • Upon entry into the SDM, the LED will blink the contents of the error buffer.
  • Error-codes greater than/equal to 10 are shown in the following manner: A long blink of 750 mSeconds indicating the decimal digit, followed by a pause of 1500 mSeconds.
  • The LED will then blink the number equal to the error code.
  • When all error-codes are displayed, the sequence is finished with an LED display of 3 seconds.
  • At this point the sequence will begin again.
Example: [Error code position 1 2 3 4 5.]
Error buffer: 12 9 6 0 0
After entering SDM:
  • The sequence will begin with 1 long blink of 750 mSeconds, then pause 1500 mSeconds, then blink twice (indicating error code 12), then the LED will pause for 3 seconds, then blink 9 times (indicating error code 9), then the LED will pause for 3 seconds, then blink 6 times (indicating error code 6), then pause 3 seconds and blink for 3 seconds again, ending the blinking sequence.
If errors 1, 2, 3, or 4 occur the LED ALWAYS blinks indicating the last error, which occurred, even if the set is NOT in service mode.
TROUBLESHOOTING TIPS
Power Supply Circuit
   When the set is turned On, the Main Switch Mode power supply is turned On This supply produces the +130 volt, +32 volt,-32 volt, two +15 volt, and Audio supplies. When IC 7302 develops a normal steady state operation, resistors 3324,3323, and 3322 sample the 130-volt supply. This sample voltage is then sent to shunt regulator 7303, which drives the feedback opto isolator 7303.The feedback voltage on Pin 14 is then compared with an internal 2.5 volt reference by comparator "C". Comparator "C" then sets the reference voltage on the inverting side of comparator "B" to control the On time of the drive at Pin 3.If the voltage on Pin 14 increases due to the 130 volt supply increasing, the On time of the pulse on Pin 3 will be reduced. If the 130 volt supply decreases, the voltage on Pin 14 would decrease, causing the On time of the pulse on Pin 3 to increase. This is used to keep the 130 volt supply at the correct voltage. Variable resistor 3322 is used to adjust the 130-volt supply to the correct level.
   The over voltage protection circuit of the IC will shut the IC down if the VCC level on Pin 1 exceeds 17 volts.  To troubleshoot this circuit, first check the On/Off line from the Small Signal Panel to ensure that it is going Low. Then check for the presence of start up voltage on Pin 1 of the regulator IC 7302.If the IC is working correctly, this voltage will be changing from 9.4 to 14.5 volts. If the start up voltage is not present, check the start-up resistor 3300 and the bridge rectifier. If the voltage on Pin 1 is changing, check the drive signal on Pin3. Then check for signal on the gate and drain of 7301.An excessive load on the secondary, a short on the 130 volt line for example, would cause the supply to pulse with little or no voltage on the secondary.

CONVERGENCE ADJUSTMENTS
   The set should be warmed up for at least 20 minutes prior to making any Geometry or Convergence adjustments. A signal must be applied to the set while performing Convergence or Geometry alignments. This is necessary to provide the correct horizontal and vertical sync to the Convergence panel. Failure to do so will result in an out of convergence picture when signal is applied to the set. The Serviced Technician should sit at least 5 to 10 feet from the front of the screen while doing Convergence. Ensure that you are eye level with the area of the screen you are adjusting. When performing Digital Convergence, the adjustments are
interactive. A change in one quadrant will affect adjacent areas of the screen. Several passes through the Convergence sequence may be necessary. When doing Convergence, it is advised to follow the sequence pattern when going from on adjustment location to another. Pressing the Right Cursor key will sequence the Icon through a pre-loaded sequence. 
   When the Convergence error is small, a touch up Convergence will be all that is necessary. Do not adjust Green Geometry while in this mode. A compete in-depth Convergence is required when the Small Signal Module (SSM) or the Convergence Memory IC, has been replaced.  If the SSB (Small Signal Board) or the Large Signal Board (LSB) has been replaced, a complete in-depth Geometry should be completed before Convergence is adjusted. The Geometry alignment should not be necessary if the SSB or LSB have not been changed.
SCREEN TEMPLATES
When performing a complete in-depth Convergence alignment, a Screen Template is necessary to obtain the correct Geometry. The correct Templates are listed below:
43 INCH => ST4168
50 INCH => ST4169
55 INCH => ST4170
60 INCH => ST4171
64 INCH => ST4172
TOUCH-UP CONVERGENCE
   Enter the Digital Convergence Mode (DCM) by entering 0-6-2-5-9-7-(Status or Index) on the Remote control. The following menu will appear:  Select an active channel or Aux Input. A signal must be applied to the set when performing convergence. If any Customer Adjustments need to be made, the Menu button can be used to toggle between the Customer Menu and DCM. The MPOSD ADJUST is used to center the Customer Convergence grid. A highlighted cross will appear along with the Convergence alignment grid. The highlighted cross should be centered onto the center of the Convergence grid.  To perform a Touch Up Convergence, highlight SELECTION and press the right cursor button on the remote.
The following menu will appear:
Selections STORE, RESTORE FACTORY, and RESTORE DEFAULT are not shown after selecting SELECTION.
Press the cursor down button on the Remote for these selections to appear.
RESTORE FACTORY loads Convergence defaults from the Factory Loaded section of the Convergence Memory IC.
RESTORE DEFAULT loads Convergence defaults from the sets software.
PERFORMING TOUCH-UP CONVERGENCE
  • Enter the Convergence Mode and select RED TO GREEN or BLUE TO GREEN. Do not select GREEN (Green Geometry) without placing a Template over the screen. To perform Green Geometry, refer to the complete in-depth Convergence.
  • Use the Cursor buttons on the Remote to Navigate from one adjustment point to another. Press the Status or Index button on the Remote to select ADJUSTS. Use the cursor buttons on the Remote to adjust the Red to Green or Blue to Green. Press the Status or Index button again to navigate to the next adjustment location.
  • After Convergence alignments are complete, press the Menu button on the Remote to return to the SELECTION menu.
  • Highlight the STORE selection and press the right cursor key on the Remote to save changes.
  • Use the GREEN TO RED or GREEN TO BLUE selections to perform convergence when the Green CRT has been replaced.
CENTERING THE SCREEN
  • Make sure a signal is applied to the set.
  • Enter the Convergence mode by entering 0-6-2-5-9-7-(Statusor Index). Select an active channel or input. If the Customer settings need to be adjusted, pressing the Menu button will access the Customer menu.
  • Place a Template over the screen.

CONVERGENCE ADJUST PROCEDURE
  770-790 series PTV incorporates a Digital Convergence Panel. This panel does not contain the familiar three rows of adjustment potentiometers as employed in the past PTV systems. Instead geometry and screen convergence settings are contained within EEPROM located on the Digital Convergence Panel. These settings may be easily modified through the following procedures.
  • When aligning the digital convergence, the adjustments are very interactive in that a change in one quadrant will potentially effect other areas of the screen; thus, requiring several alignment passes through the convergence sequences.
  • A convergence panel severely out of convergence will not necessarily have perfect icon shapes. It’s not uncommon to see bent or twisted icons.
  • In some instances to initiate icon movement with one of the arrow functions on the remote transmitter, it may require the technician to hold the desired button for several moments to see movement. This is normal. If movement doesn't occur, continue alignment sequence in other areas of the screen (use icon positioning keys 2,4,6,8), then return to the problem area of the screen. The technician may need to save present settings then exit to the convergence menu, and then return to the problem area of the screen.
  • Remember the adjustment points are highly interactive with each other. A change in one quadrant of the screen could affect other areas.
  • When converging be sure you’re at eye level with the area of the screen you are adjusting.
  • When converging a PTV, it is not required to follow the pre-defined sequence of adjustment points. When converging or adjusting the green geometry of a set that is severely out of convergence, begin at the outer regions (edges) of the set, working in a circular pattern towards the middle. Only move the icon a short distance towards the target point, then continue circling the outer perimeter moving each sector partially.
Digital Convergence Alignment of the Chassis consists of any one or a combination of the following procedures described below.
  • The first procedure "Convergence Touch Up" allows for minor convergence adjustment of anycolor. With "Convergence Touch Up" it's assumed that one or two of the colors are geometrically correct and used as reference for the color/s requiring alignment. This alignment is required for minor convergence adjustments, single yoke or CRT replacements and any physical alteration of a single Lens/CRT Assembly. 
  • The second procedure "Mechanical Alignment" is required with Major Convergence and Geometry Alignments, Yoke replacement, Convergence Module Replacement and the replacement of a CRT or physical alteration of the Lens/CRT Assembly.
  • The third procedure "Major Convergence/Geometry Alignment" is required when a Convergence Module or all three CRT's are replaced. This procedure is also required if the Green Geometry requires adjustment. Note: If the Screen Geometry of the Red or Blue gun is correct, use the "Convergence Touch Up" procedure to converge the green using the Red or Blue as a reference.
The set should be warmed up for at least 20 minutes prior to making any Convergence or Geometry adjustments.
CONVERGENCE SERVICE MODE PROCEDURE
Note:  This procedure is required for all of the following geometry and convergence adjustments.
Using the remote transmitter, enter the following seven-button sequence to activate the convergence mode. [06 -25 -97 -Menu (M)]
The "Opening Menu" will appear offering choices:
Channel 3
Use Channel ▲/▼  to Select a Channel with Video.
Remote control key functions:
▲, ▼, ◄, ►: Adjust Convergence
M: Advance "cross" location ▲, ▼, ◄, ►
To  Exit Convergence
Status: Abort/Cancel Changes
M: Begin Convergence.
[Video information must be present to correctly adjust the convergence. A signal source is required to lock the vertical and horizontal sync. After entering the "convergence service mode," verify the presence of a video source by confirming the presence of active audio (use the volume up function on the remote).
Use the channel up and down function on the remote to select the desired tuning source.]
Select item "M" from the first menu, the "Convergence Menu" will appear featuring 5 possible selections.
Channel 3. Convergence:
green geometry
  • Red To green Convergence
  • Blue To green Convergence
  • Green To red Convergence
  • Green To blue Convergence
  • Status: Abort/Cancel Changes
CONVERGENCE TOUCH-UP PROCEDURE
  • Enter the "convergence service mode" as described above in the "convergence service mode procedure".
  • Select the desired color requiring adjustment.  Note: Do not select Green Geometry (1). This procedure is described under "Major Convergence/Geometry Alignment. If Green Geometry is altered during this procedure a "Major Convergence/Geometry Alignment" maybe required.
  • Cover the Output Lens of the single color presently NOT being adjusted. Example: If you select Green to Red Convergence (4) cover the Blue Output Lens.
  • The highlighted adjustment Icon (Cross) should be illuminated on the middle left side of the screen. Make the necessary Convergence Adjustments using the following Remote Keys:
Use the Arrow Up (▲ ) to adjust the selected color up.
Use the Arrow Down Key (▼ ) to adjust the selected color down.
Use the Arrow Right Key (-) to adjust the selected color to the right.
Use the Arrow Left Key (+) to adjust the selected color to the left.
Move to the next location to be converged. It is not required that the full Convergence Sequence be followed while performing the "Convergence Touch Up Alignment Procedure".
The following alternate Remote Keys allow for positioning of the Icon to the desired adjustment location:
  • Key 2 on the Remote Transmitter will position the Adjustment Icon upward on the screen.
  • Key 8 on the Remote Transmitter will position the Adjustment Icon downward on the screen.
  • Key 4 on the Remote Transmitter will move the Adjustment Icon to the Left.
  • Key 6 on the Remote Transmitter will move the Adjustment Icon to the Right.
  • Return to the "Convergence Service Menu" by selecting Key number 3 on the remote transmitter or by sequencing the Icon to the last adjustment point at the lower right corner of the screen and pushing the Menu (M) Key on the Remote Transmitter.
  • Repeat steps 1 through 6 for other required Convergence Alignments.
  • To Save the Adjustment completed in the last procedure, Exit/Save the Convergence Service Mode by selecting Key 1 on the Remote Transmitter. This forces the corrections to be written to the EEPROM on the Convergence Module.
{To save the convergence corrections made above you must exit the convergence menu by selecting Exit/Save Data (1)}

CONVERGENCE CENTER FREQUENCY ADNUSTMENT
[This adjustment should not be done unless a component on the PLL circuit has been replaced]
  • Connect a voltmeter from TP3 on the convergence board to cold ground (use top shield).
  • Adjust L3 to obtain 1.5Vdc.
MAJOR CONVERGENCE/GEOMETRY ADJUST
Major Convergence/Geometry alignment procedures are required when replacing the Digital Convergence Module or all three CRT's require replacement.
The following procedure must be followed in the order listed to insure satisfactory results.
Use the following order to converge a set requiring "Major Convergence/Geometry Alignment":
  • CRT Centering using the Centering Tabs around the Yoke.
  • Align the Convergence by first setting the Green Geometry using the "Convergence Template" and following up with the Red and Blue Convergence Alignment.
{The part number for ordering the Screen Template Kit is: ST4130. This kit contains all the templates for all screen sizes required for the PTV770 through PTV788 series. For individual screen templates, add the screen size to the kit number. Example: ST4130-46 is the individual part number for the 46'' Screen Template.}
CRT SCREEN CENTERING [MECHANICAL]
  • Locate the Screen Center by placing strings diagonally across the viewing area of the screen from corner to corner. The Screen Template, if centered correctly on the screen, can also provide the center point location.
  • Enter the "Service Setup Mode" (06-25-96-Menu-Menu) and confirm approximate register values of the following registers:  Note: Confirming the following register values is not required if the Small Signal or Large Signal Boards have not been replaced or altered.
  • Connect a Signal Source (pattern generator) to the antenna terminal of the set. A signal source must be present while following these procedures.
  • Enter the Convergence Service Mode as described above in the Convergence Service Mode Procedure.
  • Place a jumper wire from pins 1 to 2 of test point 4 (tp4) on the convergence panel.
  • Select "1" Green Geometry from the Convergence Service Mode Menu. Cover the Red and Blue output lens using a 7" X 7" piece of cardboard.
  • The highlighted icon (cross) maybe visible on the left side of the screen about half way up. Position the icon at the screens approximate center by pressing the M on the remote transmitter 3 times.
  • Using the Centering tabs of the yoke, position the highlighted Green icon to the screen center as defined by the diagonal strings positioned across the viewing area of the screen or using the center point on the screen template.
Note: In some cases there may be insufficient range with the centering tabs to position the Green icon to the screens center. In this case position the icon as close as possible to the screen center.
  • Confirm the centering by viewing the screen from the front of the unit.
  • Return to the Convergence ServiceMode Menu by selecting number 3 on the remote transmitter. Select number "2" on the remote to activate the "Red to Green" Convergence. Cover the Green and Blue output lenses with a 7" X 7" piece of cardboard. Repeat step 7 through 9 using the Red yoke Centering Tabs.
  • Return to the Convergence Service Mode Menu by selecting "3" on the remote transmitter. Select "2" to repeat convergence. Select "3" on the remote to activate the "Blue to Green Convergence". Cover the Red and Green output lenses with a 7" X 7" piece of cardboard. Repeat step 7 through 9 using the Blue yoke Centering Tabs.
  • Exit the convergence mode by selecting the Status Exit function on the remote transmitter. Remove the 7" X 7" pieces of cardboard from the output Lenses. CRT centering is complete.
  • Remove the jumper from TP4 on the Digital Convergence Module.
GREEN GEOMETRY
{The Green Geometry must be accurately adjusted to achieve proper convergence and screen geometry. The Red and Blue displays will individually be made to conform to the Green.}
  • Confirm the CRT Centering as described in the previous procedure.
  • Remove the protective screen enhancement filter (if present) to make the following adjustments.
  • Attach the "Screen Template" to the screen using a low tac tape.
  • Enter the Convergence Service Mode by selecting 06-25-97-Menu with the Remote Transmitter.  Note: Video information must be present to correctly adjust the convergence. This can be checked by the presence of audio on the channel selected.  Select Mto begin the convergence adjustments.
  • Select "1" Green Geometry. The Green icon should be positioned near the left edge of the screen and on the middle row of the template If not visible hold the right arrow key of the Remote Transmitter until the icon is visible on the screen. Use the M key to position the icon on the next horizontal point in the convergence sequence. Move the Green icon using the Remote Transmitter arrow buttons Only Half Way towards the next template point. Continue through the whole Green Geometry Sequence moving the Green icons Only Half Way towards the target point on the template. Upon reaching the End Here point on the template press the M to recalculate.
  • Select Repeat Convergence by selecting the number "2" on the Remote Transmitter. Select Green Geometry number 1 on the Remote Transmitter. Follow the Green Geometry Sequence through a second pass, this time accurately aligning the Green icon to the alignment points on the template. Repeat the Green Geometry Sequence as required. When completed Exit/Save the changes by entering the converging page and selecting 1.
  • Confirm the accuracy of the Green Geometry.
