How to Activate SDM [Service Default Mode]
To activate SDM, use the following methods:
• Press the following key sequence on the RC transmitter: “062596”, directly followed by the “Home” button. After activating this mode, “SDM” will appear in the upper left corner of the screen.
How to Exit SDM
• Switch the set to Stand-by by pressing the standby button on the remote control transmitter or on the television set.
• Via a standard customer RC-transmitter: key in “00”-sequence.
Note: If the TV is switched “off” by a power interrupt while in SDM, the TV will show up in the last status of SDM menu as soon as the power is supplied again. The error buffer will not be cleared.
How to Activate SAM [Service Alignment Mode]
To activate SAM, use one of the following methods:
• Press the following key sequence on the remote control transmitter: “062596”, directly followed by the “INFO” button. Do not allow the display to time out between entries while keying the sequence.
• Or via ComPair.
After entering SAM, the following items are displayed, with “SAM” in the upper right corner of the screen to indicate that the television is in Service Alignment Mode
How to Store SAM Settings
To store the settings changed in SAM mode (except the RGB Align settings), leave the top level SAM menu by using the POWER button on the remote control transmitter or the television set. The mentioned exceptions must be stored separately via the STORE button.
How to Exit SAM
Use one of the following methods:
• Switch the set to STANDBY by pressing the mains button on the remote control transmitter or the television set.
• Via a standard RC-transmitter, key in “00” sequence.
The Blinking LED Procedure.
The software is capable of identifying different kinds of errors. Because it is possible that more than one error can occur over time, an error buffer is available, which is capable of storing the last five errors that occurred. This is useful if the OSD is not working properly. Errors can also be displayed by the blinking LED procedure. The method is to repeatedly let the front LED pulse with as many pulses as the error code number, followed by a period of 1.5 seconds in which the LED is “off”. Then this sequence is repeated.
Example (1): error code 4 will result in four times the sequence LED “on” for 0.25 seconds / LED “off” for 0.25 seconds. After this sequence, the LED will be “off” for 1.5 seconds. Any RC command terminates the sequence. Error code LED blinking is in red color.
Example (2): the content of the error buffer is “12 9 6 0 0” After entering SDM, the following occurs.
• 1 long blink of 5 seconds to start the sequence.
• 12 short blinks followed by a pause of 1.5 seconds.
• 9 short blinks followed by a pause of 1.5 seconds.
• 6 short blinks followed by a pause of 1.5 seconds.
• 1 long blink of 1.5 seconds to finish the sequence.
• The sequence starts again with 12 short blinks
Additionally, the entire error buffer is displayed when Service Mode “SDM” is entered.
ERROR CODES
Error codes are required to indicate failures in the TV set. In principle a unique error code is available for every:
• Activated (SW) protection.
•Failing I2C device.
• General I2C error.
The last five errors, stored in the NVM, are shown in the Service menu’s. This is called the error buffer. Theerror 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, it is displayed at the left side and all other errors shift one position to the right. An error will be added to the buffer if this error differs from any error in the buffer. The last found error is displayed on the left. An error with a designated error code never leads to a deadlock situation. It must always be diagnosable (e.g. error buffer via OSD or blinking LED or via ComPair). In case a failure identified by an error code automatically results in other error codes (cause and effect), only the error code of the MAIN failure is displayed.
How to Read the Error Buffer
You can read the error buffer in three ways:
• On screen via the SAM/SDM/CSM (if you have a picture).
Example:
– ERROR: 000 000 000 000 000: No errors detected
– ERROR: 013 000 000 000 000: Error code 13 is the last and only detected error
– ERROR: 034 013 000 000 000: Error code 13 was detected first and error code 34 is the last detected (newest) error.
• Via the blinking LED procedure (when you have no picture).
Option Settings
The microprocessor communicates with a large number of I2C ICs in the set. To ensure good communication and to make digital diagnosis possible, the microprocessor has to know which ICs to address. The presence / absence of these MT5366 ICs is made known by the option codes.
After changing the option(s), save them by pressing the OK button on the RC before the cursor is moved to the left, select STORE and press OK on the RC.
The new option setting is only active after the TV is switched “off” / “stand-by” and “on” again with the mains switch (the NVM is then read again).
Option Code Overview
Enter SAM mode to check the option codes. They could not be edited in the NVM.
Display Code Overview
Press the following key sequence on a standard RC transmitter: “062598” directly followed by MENU and “xxx”, where “xxx” is a 3 digit decimal value of the panel type: see column “Display Code” in Table. After resetting the Display Code, restart the set immediately.
Display code overview Table
Reset of Repaired SSB
A very important issue towards a repaired SSB from a Service repair shop (SSB repair on component level) implies the reset of the NVM on the SSB. A repaired SSB in Service should get the service Set type “00PF0000000000” and Production code “00000000000000”. Also the virgin bit is to be set. To set all this, you can use the ComPair tool or use the “NVMeditor” and “Dealer options” items in SAM (do not forget to “store”).
After a repaired SSB has been mounted in the set (set repair on board level), the type number (CTN) and production code of the TV has to be set according to the type plate of the set. For this, you can use the NVM editor in SAM. The loading of the CTN and production code can also be done via ComPair (Model number programming).
In case of a display replacement, reset the “Operation hours display” to “0”, or to the operation hours of the replacement display.
SSB Indentification
SSB’s of this chassis are identified by a “715” code on the SSB. 715Axxxx-Nnn-MMM-OOOO
• 715main category, Printed Wiring Board
• Axxxxsub category, sequential coding number
• NnnVersion code
• NDevelopment number
• nnProduction number
• MMMMounting variation code
• OOOOOptional variation code
Make sure when replacing an SSB the SSB identification codes match the replacement board.

SELF DIAGNOSISThis monitor is equipped with a self-diagnosis function. If there is a problem with your monitor or computer (s), the screen will go blank and the (power) indicator will either light up green or flash orange. If the (power) indicator is lit in orange, the computer is in power saving mode. Try pressing any key on the keyboard or moving the mouse.
If the (power) indicator is green
1 Turn off the AC power switch and disconnect the video signal cables from the INPUT1 and INPUT2 connectors of the media engine.
2 Press the AC power switch twice to turn the monitor off and then on. If all four color bars appear (white, red, green, blue), the monitor is working properly. Reconnect the video input cables and check the condition of your computer(s).
If the color bars do not appear, there is a potential monitor failure. Inform your authorized Sony dealer of the monitor’s condition.
If the (power) indicator is flashing orange
Press the (power) switch twice to turn the monitor off and then on.
If the (power) indicator lights up green, the monitor is working properly.
If the (power) indicator is still flashing, there is a potential monitor failure. Count the number of seconds between orange flashes of the (power) indicator and inform your authorized Sony dealer of the monitor’s condition. Be sure to note the model name and serial number of your monitor. Also note the make and model of your computer and graphic board.↧
