Errors can 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 RC5 command terminates the sequence.
Error code LED blinking is in red colour.
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.
DISPLAYING ENTIRE ERROR BUFFER
the entire error buffer is displayed when Service Mode “SDM” is entered. In case the TV set is in protection or Stand-by: The blinking LED procedure sequence (as in SDM mode in normal operation) must be triggered by the following {RC sequence: “MUTE” “062500” “OK”.}
In order to avoid confusion with RC5 signal reception blinking, this blinking procedure is terminated when a RC5 command is received.
To erase the error buffer, the RC command “MUTE” “062599 “OK” can be used.

- Some of the error codes reported are depending on the option code Configurations.
- This error means: no I2C device is responding to the particular I2C bus. Possible causes: SCL/SDA shorted to GND, SCL shorted to SDA, or SCL/SDA open (at uP pin). The internal bus of the Trident platform should not cause the entire system to halt as such an error can be reported.
