TO TAKE OUT A DISC WHEN NOT EJECT (FORCE EJECT)

Remove the screw (M1.7) and front cover (227).

Insert the wire etc. in the hole and up the lock arm by it.

Self-diagnosis Display
When problems occur while the unit is operating, the counter of the viewfinder or LCD screen shows a 4-digit display consisting of an alphabet and numbers, which blinks at 3.2 Hz. This 5-character display indicates the “repaired by:”, “block” in which the problem occurred, and “detailed code” of the problem. Insert the wire etc. in the hole and up the lock arm by it.

SELF DIAGNOSIS WINDOW & CODE DETAILS

PROCESS AFTER FIXING FLASH ERROR

When “FLASH error” (Self-diagnosis Code E:91:01) occurs, to prevent any abnormal situation caused by high voltage, setting of the flash is changed automatically to disabling charge and flash setting.
After fixing, this setting needs to be deactivated. For the method of the error release, refer to “6.Record Data, Initializing method (All Record-Data)” in service manual, ADJ. Note: The error cannot be released only by initializing only the self-diagnosis data, be sure to execute the initialization of all record-data to release the error.

DISCHARGING OF THE ST-154 BOARD’S CHARGING CAPACITOR (C5206)

The charging capacitor (C5206) of the ST-154 board is charged up to the maximum 330 V potential.  There is a danger of electric shock by this high voltage when the capacitor is handled by hand. The electric shock is caused by the charged voltage which is kept without discharging when the main power of the unit is simply turned off. Therefore, the remaining voltage must be discharged as described below.

The KLV-40ZX1M is an ultra-thin LCD monitor measuring a meager 1”- 1/8” (9.9mm) in depth and weighs only 26 pounds. As mentioned, this is a monitor, so it does not contain a RF tuner to receiver television programming. Furthermore, there is only one video/audio input on this model - the digital high-quality HDMI input. Therefore, to receive and display channel programming a STB or DVR with an internal RF tuner must be connect to the HDMI input. The monitor can also be connected to a DVD or Blu-ray player through the HDMI connector to receive high quality video and audio.
The LCD panel is a Full High-Definition 1080p resolution panel. The back-light is produced using a Wide Color Gamut LED edge light system.
This system provides high contrast ratio with more accurate color and blacker blacks. To further enhance the color reproduction a 10-bit processor and 10-bit panel are combined in this model.  The model also includes the Motionflow™ 120Hz technology which enhances sharpness and delivers smooth motion for fast-action sports and movies. And finally, this model contains the BRAVIA® Engine™ 2 fully digital video processor.

TROUBLESHOOTING

Power System Troubleshooting
Normal Operation
IC on the LD1-Board.
110VAC is applied to the GS1-Board, and can be measured at CN6000.  In the standby mode the AC power passes through the main fuse F6001, R6001 (Inrush resistor), and BD6001 and is applied to the Main DC/DC Converter IC6501 and the Standby DC/DC Converter IC6200. IC6501 is not active in the standby mode. However, IC6200 is active in standby mode and outputs STBY 3.3Vdc as long as AC power is applied to the TV (and the GS1-Board). The Standby 3.3Vdc is supplied to the BEMicroprocessor, H1L-Board (Power Key), and H4L-Board (IR Sensor) in the standby mode.
Once an ON command is received form the remote controller or the power button on the H1L-Board the BE-Microprocessor outputs the Power-ON
signal. The Power-On signal is applied to the GS1-Board. On the GS1- Board the Power-On signal switches the 19V from the standby power
supply to activate the relay (RY6001), PFC, and Main Power supply. One relay click is heard at power-on. The relay engages to bypass the inrush
resistor R6001 during the ON state.

The BE-Microprocessor also outputs additional Power.-On signals to activate all the voltage regulators on the B-Board to complete the TV power on sequence
The main power supply IC6501 is now active and outputting a single 12Vdc secondary supply. This single 12Vdc secondary supplies the following four sections in the TV.
B-Board Audio Output Amplifier (AU12Vdc)
B-Board Voltage Regulators (Reg 12Vdc)
BT3-Board (Reg 12Vdc)
LD1-Board (Reg 12Vdc)
The GS1-Board also supplies 390Vdc and 18Vdc to the LD1-Board (LED Back-light Power Board). The 390Vdc supplies each converter high-power output switching transistors, and the 18V is the VCC for each converter.

Failure Symptoms
An actual power supply (GS1-Board) failure will cause one of the following failure symptoms.
> No Power/Dead Set (AC LVP or STBY 3.3Vdc)
> 2X Protection Blink Pattern (12Vdc LVP or OVP)
> 6X Protection Blink Pattern (18Vdc LVP)

NOTE: The protection LED blink patterns occur using the RED Power LED at the lower right of the front panel.

No Power/Dead Set (TV will not Turn ON)
In a dead set condition there will be No Green Power-LED illumination and No Relay Click.
The following bullet list gives the possible failures for a “No Power/Dead Set” condition.
* Loss of AC Power (AC Outlet)
* Loss of AC_OFF_DET (GS1-Board)
* Loss of Standby 3.3Vdc (GS1-Board)
* Defective Main Microprocessor (B-Board)
The first step in troubleshooting a “No Power/Dead Set” condition is to confirm that 110VAC power from an active AC outlet is applied to the GS1-Board. AC power is applied to, and can be measured at CN6000 on the GS1-Board. After confirming that AC power is applied to CN6000 check that the AC is detected by the GS1-Board. Check the AC_OFF_DET voltage at CN6157/pin 2. The voltage level should be 3.3V when the GS1-Board successfully detects the AC power input. If the voltage is 0V a dead set condition will occur. In this case, replace the GS1-Board.  After confirming the AC power, check for a defective Standby 3.3Vdc power supply IC6200. To confirm a defective IC6200 check the 3.3V secondary voltage at N6157/pin 3. As long as AC power is applied to the TV IC6200 should be active and outputting 3.3Vdc.tection LED blink patterns occur using the RED Power LED at the lower right of the front panel.

Finally, a “Dead Set” condition can be caused by a defective BE microprocessor IC3001. The main microprocessor outputs the Power On signal which activates switch Q6404 and passes the 19V from the Standby power supply to activate the relay, PFC, and Main Power Supply on the GS1-Board. If the Power-On signal is not output after receiving the power-on command the GS1-Board circuits remain inactive and a “Dead Set” condition exists. The Power-On signal can be checked at CN6157/ pin 1. It should measure approximately 3V.dc If the measurement is 0Vdc before shut-off the BE microprocessor is defective.

2X Protection Mode Blink Pattern
A loss or excessive condition of the 12Vdc secondary voltage from the main power supply IC6501 will cause a 2X blink pattern on the Power LED. The 12Vdc can be checked at CN6156/pin 3.  If the measurement is 0V or rises above 12Vdc before the TV shuts-off the GS1-Board is defective.
If approximately 12Vdc is present and remains below 12Vdc before shutoff then the B-Board is defective. Before replacing the GS1-Board for a failure confirm that the B-Board is sending the Power-On command to turn on the power supply circuits on the GS1-Board. The Power-On voltage can be checked at CN6157/pin 1.
The normal voltage level at power-on is 3Vdc.
If the 3Vdc is not present before shut-off replace the B-Board. If the 3Vdc is present replace the GS1-Board.

6X Protection Mode Blink Pattern
Although a 6X protection blink pattern normally indicates a back-light error, a defect on the GS1-Board can cause this indication. A loss of the 18Vdc
from the main power supply on the GS1-Board will cause a 6X. Because the 18Vdc is the supply voltage to the LD1-Board back-light converter ICs, a loss of it causes no converter function, and consequently no back-light and 6X. The 18Vdc can be checked at CN6501/pin 3. The voltage should measure approximately 18Vdc before shut-off. If measurement is 0Vdc the GS1-Board is defective. If 18V is present the LD1-Board is defective.

LED Backlight System Troubleshooting

Normal Operation
The LD1-Board is the power supply for the LED back-lighting. It takes the 390Vdc from the GS1-Board and converts it to highly regulated positive and negative 58Vdc to 95Vdc LED drive voltages. These voltages can be measured at CN6781, CN6782, CN6783, and CN6784.
Control voltages from the B-Board are also supplied to the LD1-Board.
The BL_ON signal turns on the back-lights. The Dimmer controls the back light level. The INV_ERR which is normally low goes to 3V during a back-light error. The panel back-lighting illuminates approximately 5 seconds after the H1LBoard or remote control power button is pressed. The back-light remains illuminated and the information banner is immediately displayed. The video is then display after another 2 seconds.

Failure Symptoms
NOTE: The protection LED blink patterns occur using the RED Power LED at the lower right of the front panel.
An actual Back-light (LED) or Back-light power supply (LD1-Board) failure will cause one of the following failure symptoms.
No Backlight & 6X Protection Blink Pattern
Momentary Back-light & 6X Protection Blink Patter
The first step in troubleshooting a back-light error is to view the screen and note the state of the back-light before shut-off and 6X. Does the back-light momentarily illuminate or is there no back-light at all? This one step provides valuable information in locating the defective component.  Reference the following two sections for more details concerning each symptom.

No Backlight & 6X Protection Blink Pattern
Video and audio may or may not be present before shut-off. Although there is no backlight the presence of video can be confirmed by shining a flashlight on the front TV screen. Video can be seen in the lighted area.
NOTE: To confirm that the LD1-Board is actually detecting a backlight failure check the INV-ERR volatge at CN6780/pin 1. The voltage will go high 2V at power on and then low 0V when the back-light is turned off.
This cycle will occur twice as the microprocessor makes two attempts to illuminate the back lights. After two attempts the TV shuts off and a 6X blink pattern is activated.
The following failures can cause a “No Back-light & 6X“ condition.
Defective LD1-Board
Loss of 18Vdc (GS1-Board)
Loss of BL_ON/OFF Signal (B-Board)
Loss of 390Vdc (GS1-Board - connection only)
Loss of 12Vdc (GS1-Board - connection only)
Before replacing the LD1-Board check the supply voltages and control signal needed for proper function of the board. First check the 18Vdc supply from the GS1-Board at CN6721/pin 3. If the 18Vdc in missing replace the GS1-Board.

If the 18V is present check for the BL_ON control signal from the B-Board.  The BL_ON is normally 3V at CN6780/pin 2. If this voltage is missing
replace the B-Board.  If the power-on 3V is present then check the 390Vdc and 12Vdc connections between the GS1-Board and the LD1-Board. Check the following physical connections as indicated.
>> 390V - CN6500 (GS1-Board) to CN6720 (LD1-Board)
>> 12V - CN6157 (GS1-Board) to CN6780 (LD1-Board)
If all the previous voltages and the control signal check okay and the TV still shuts-off and indicates a 6X replace the LD1-Board.

Momentary Backlight & 6X Protection Blink Pattern
The following two failures can cause a “Momentary Backlight & 6X” condition.
Defective Panel LED or LEDs
Defective LD1-Board (single voltage output)
NOTE: To confirm that the LD1-Board is actually detecting a back light failure check the INV-ERR voltage at CN6780/pin 1. The voltage will go high 2V at power on and then low 0V when the back light is turned off.
This cycle will occur twice as the microprocessor makes two attempts to illuminate the back lights. After two attempts the TV shuts off and a 6X blink pattern is activated.  When the TV is initially turned on the back light will momentarily come on 2 times and then the TV shuts-off and indicates a 6X protection blink pattern. The back light system makes 2 attempts to light the LEDs. The AC relay clicks three times with a few seconds between each click. After the final relay click the 6X is activated.
First check the LD1-Board outputs at CN6781, CN6782, CN6783, and CN6784. The voltage measurement at CN6781 and CN6783 will be a positive 56Vdc to 95Vdc level, and the measurement at CN6782 and CN6784 will be a negative 56Vdc to 95Vdc level. The labels on the connectors are as follows 

LS-B (Bottom Edge)
LS-T (Top Edge)
LS-R (Right Edge)
LS-L (Left Edge)
The bottom and top voltages will measure towards the 85Vdc level and the left and right voltages will measure towards the 70Vdc level.  If one or more outputs are missing replace the LD1-Board.  If all the voltages are present and the TV is still shutting off and indicating a 6X blink pattern then the LCD Panel assembly is defective.

LCD Panel Assembly
The LCD Panel Assembly includes the LCD Panel, BT3-Board (TCON/HFR), and LED Back-light system.
The LCD Panel contains the actual liquid crystals, color filters, and polarizers. The liquid crystals are manipulated by the applied voltage to pass a specific amount of light - from the back-light- depending on the level of voltage applied. The panel resolution on the EX1S chassis model is 1920 X 1080 lines. This is considered a 1080P Full High-Definition model.
The BT3-Board (TCON & HFR) performs all the control, timing, charge, and discharge functions driving the operation of the LCD Panel. The HFR (High-White LED Edge Back-light System)
The top, bottom, left, and right edge LEDs generate the white light that is captured and evenly spread across the panel by a Light Guide Plate. The captured light then passes through the liquid crystals in the LCD Panel. The light guide operates in the same way a fiber optic cable operates. There is a light source which generates the light and the fiber optic cable (glass fibers) retains the light within its boundaries.

LD1-Board
This board contains three power converter circuits to drive the top, bottom, left, and right edge LED backlight system. The drive outputs for the LED system are between 56Vdc and 95Vdc.

B-Board
The circuits located on the B-Board perform all Video and Audio processing functions. It also contains all the microprocessor control circuits. The
following circuits are included on this board.
BE (TV) Microprocessor
TRIDENT Processor
- Video Signal Processing
- HDMI Signal Processing
- Scan Converter
- HDCP Processing
Audio DSP
Audio Amplifier
Temperature Sensor

GS1-Board
Except for some regulator circuits on the B-Board, the GS1-Board is the power supply system board, which includes the following components and circuits.
Main Power Supply [ 12V for Audio, BT3-Board, and LD1-Board Circuits]
Standby Power Supply [ 3.3V for standby circuits]
390V for Backlight Circuits (LD1-Board)
18V for Backlight Circuits (LD1-Board)
