SONY-SXRD PROJECTION TV KDS-50A200 50A2010 55A2000 60A2000 60A2010 - LED BLINKING CODES

SONY-SXRD PROJECTION TV  KDS Series - LED Blinking Codes

     This device includes a self diagnosis function.  In case of abnormalities, the power indicator automatically blinks.  It is possible to predict the abnormality location by number of blinks.  If the symptom is not reproduced sometimes in case of a malfunction there is recording of whether a malfunction was generated or not.  Operate the remote command to confirm the matter on the screen and to predict the location of abnormality.
Diagnosis Items and Prediction of Malfunction Location

• When malfunction occurs the 'Power' indicator only blinks for one of the following diagnosis items.  In case of two or more malfunctions, the item which first occurred blinks.  If the malfunctions occurred simultaneously, the item with lower blink count will blink first.
• The screen display displays the result regarding all the diagnosis items listed below.  The display "0" means that no malfunctions has occurred.

Diagnosis item	Number of times the power indicator blinks	Probable cause location.	Defected symptoms
Temp. over	2 times	The periphery of the lamp heats up abnormally	No picture/no sound
Lamp cover	3 times	Lamp cover is not attached properly	No picture/no sound
Fan error	4 times	# Fan 1,3,4 poser is not supplied.  # Fan connector is not attached securely.	No picture/no sound

STOPPING THE STANDBY INDICATOR FLASH

• Turn OFF the Power switch on the TV main unit or unplug the power cord from the outet to stop standby indicator from flashing.

SELF DIAGNOSTIC SCREEN DISPLAY

• For errors with symptoms such as 'power sometimes shuts off' or 'screen sometimes go off' that cannot be confirmed, it is possible to bring up past occurrences of failure on the screen for confirmation.

TO BRING UP SCREEN TEST

• In standby mode, press buttons on the remote commander sequentially in rapid succession  as [Display > Channel-5 > Volume (-) > Power > / TV].  Note that, the volume (-) should be pressed.  If you press Volume (+), the set will enter into Service Mode, not come up screen test mode

The following screen will be displayed indicating the error count.

------------------------------------------------------

2:                                                0

3:                                                N/A

4:                                                0

5:                                               1

8:                                               0

101:                                           N/A

-----------------------------------------------------

Numerical '0' means that no fault was detected.

Numerical '1' means the number of fault occurrence (1 to 255)

HANDLING THE SELF DIAGNOSTIC SCREEN DISPLAY

• Since the diagnostic result displayed on the screen are not automatically cleared, always check the self diagnostic screen during repairs.  When you have completed repairs, clear the  result display to "0".
• Unless the display is cleared to "0", the self diagnostic fucntion will not be able to detect subsequent faults after completion of repairs.

CLEARING THE RESULT DISPLAY

• To clear the result display to "0", press buttons on the remote commander subsequent as shown below when the self-diagnostic screen is being displayed.
• [8 => 0]

QUITTING SELF DIAGNOSTIC SCREEN

• To quit the entire self diagnostic screen , turn OFF the power switch on the remote commander or the main unit.

ENTERING SERVICE MODE

• To enter service mode, press [Display => Channel-5 => Volume (+) => Power/TV]
• 'TT' will appear in the right upper corner of the screen.  Other status information will also displayed.
• Press "Menu" on the remote control to obtain service menu on the screen.
• The screen only displays '8' items at one time.  To move to the corresponding item use the "UP" or "DOWN" buttons on the remote control.
• Press [Right] or [Left] button, or "Enter" button on the remote control to enter into the required item.
• The screen only display '12' items at one time.  To move the corresponding item, use 'Up/Dn' button on the remote control.
• Press [Right] to increase of [Left] to decrease the data value to selected item.
• Press the "Menu" button on the remote control to 'Quit' from service menu.  The screen will display 'TT----'. 
• To 'Exit from 'TT-----' menu, press [0] twice. 'TEST', 'TV' or switch the TV into standby mode.

     The identification of errors within the LE3-3A chassis is triggered in one of two ways.  1: Busy or 2: Device Failure to Respond to IIC.  In the event of one of these situations arising the software will first try to release the Bus if busy [Failure to do so will report with continuous flashing LED] and then communicate with each device in turn to establish if a device is faulty.  If a device is found to be faulty the relevant device number will be displayed through the LED (Series of flashes which must be counted).

SONY NEX CHASSIS - KDL19L4000 KDL29L4000 LCD TV - SERVICE MODE - SELF DIAGNOSIS FUNCTION

IMPORTANT
These TV models "do not" contain a self diagnostic function. 
If an error occurs, whatever it may be,  the TV will not stay ON.  Therefore it is recommended that if a repair is required  for these model TV sets, the technician should have both 'A' board and the 'Power Unit Board'  of same part number should be with him to perform repair.  
It will be best to get this set repaired by any authorized service center for Sony, or by any local technician who have both the above mentioned bards with him at the time of repair.
TO ENTER SERVICE MODE [[remote control unit RM-ED014]]

• Turn ON the Power to the TV.
• Press [(i+) > 5 > Vol(+) > TV|Power] buttons on the remote control in sequence.
• Service menu will be displayed.
• To select an item to adjust, use 'Up' / 'Dn' button on the remote control.
• Press 'Right Arrow' button to enter into the required menu item.
• To adjust the data value to selected item, use 'Up' / 'Dn' button on the remote control.
• To go back to any item, use 'Left Arrow' button on the remote control.
• To "Exit' service mode, press 'RED' button or 'MENU' button on the remote control.
• After carrying out the service adjustments, to prevent the customer accessing the 'service menu' switch the TV set OFF and then ON again by its main Power Switch.

     If an error occurs, the STANDBY/TIMER LED will automatically begin to flash.  The number of times the LED flashes translates to a probable source of the problem.  A definition of STANDBY/TIMER LED flash indicators are listed here for reference.  If an error symptom cannot be reproduced, the remote commander can be used to review the failure occurrence data stored in memory to reveal past problems and how often these problems occur.
     Results for all of the following diagnostic items are displayed on screen.  No error has occurred if the screen displays a [0].
*  If a +B over-current is detected, stoppage of vertical deflection is detected simultaneously.  The symptom that is diagnosed first by the micro-controller is displayed on the screen.
