SONY KV- 32HQ100B - KV-36HQ100B - TRINITRON - SELF DIAGNOSTICS - ERROR CODES - LED BLINKING CODES

ERROR CODES & SELF DIAGNOSTIC FUNCTION
 Error diagnostics are used to diagnose if parts of the chassis are faulty. Some errors can be safety critical. In this case the TV set is put into standby.

An error is communicated by:

• Flashing the LED red at the front of the TV
• Via the error monitor service menu
• Via the Customer Service Menu (CSM)
• Via an external error reader connected to the service connector.

LED ERRORS

• The most important errors are signaled via this method.
• This is also the only way that safety critical errors can be communicated since the TV will be in standby.
• The LED sequence below is an example of Error Code 3. An error is determined by the number of short red flashes of the LED in between a longer solid green LED indication.

• LED code 1 has the highest priority.
• Errors found corresponding to LED error codes 2-4 will put the TV into standby under all conditions.
• However, an error corresponding to LED error code 5 (Unstable AKB) will only put the TV into standby in service mode – the LED will flash in production mode without the TV going into standby.

ERROR MONITOR MENU

The error monitor is displayed by:

• Entering TT command TT99, or
• Executing the following key sequence when the TV set is in standby:

The error monitor displays the following information:

• The last 5 errors that are stored in flash
• The current error
• The operating time of the TV set. 

                        Error detection can also be enabled or disabled from this menu.

The following error messages are displayed in the error monitor. The error code is displayed in the external error reader.

ERROR READER DISPLAY

• If no menu can be shown, the Error Reader can display the current error. The error reader display is connected to the service connector to read actual error codes. The part number for the error reader display is S-188-900-10. Once an error has been detected it will then be displayed on the two digit error reader. The errors displayed refer to the above table.

Due to the limited count of digits the Error Reader displays the message sequentially. The following example shows the definition of this sequence:

• Start new error sequence [ .]
• Display of 1st error part 1 [ 4 .]
• Display of 1st error part 2 [ 0 1 .] Error Code = 401h
• Display of 2nd error part 1 [ 6 .]
• Display of 2nd error part 2 [ 0 1 .] Error Code = 601h
