Error Codes
5.4.1
Introduction
Error codes are required to indicate failures in the TV set. In
principle a unique error code is available for every:
•
Activated protection.
•
Failing I2C device.
•
General I2C error.
•
SDRAM failure.
The last five errors, stored in the NVM, are shown in the
Service menu's. This is called the error buffer.
The error 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 may never lead to a
deadlock situation. This means that it must always be
diagnosable (e.g. error buffer via OSD or blinking LED
procedure, ComPair to read from the NVM).
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.
Example: In case of a failure of the I2C bus (CAUSE), the error
code for a "General I2C failure" and "Protection errors" is
displayed. The error codes for the single devices (EFFECT) is
not displayed. All error codes are stored in the same error
buffer (TV's NVM) except when the NVM itself is defective.
5.4.2
How to Read the Error Buffer
You can read the error buffer in 3 ways:
•
On screen via the SAM/SDM/CSM (if you have a picture).
Example:
–
ERROR: 0 0 0 0 0 : No errors detected
–
ERROR: 6 0 0 0 0 : Error code 6 is the last and only
detected error
–
ERROR: 9 6 0 0 0 : Error code 6 was detected first and
error code 9 is the last detected (newest) error

•
Via the blinking LED procedure (when you have no
picture). See "The Blinking LED Procedure".
•
Via ComPair.
Error Codes
In case of non-intermittent faults, write down the errors present
in the error buffer and clear the error buffer before you begin
the repair. This ensures that old error codes are no longer
present.
If possible, check the entire contents of the error buffer. In
some situations, an error code is only the result of another error
and not the actual cause of the problem (for example, a fault in
the protection detection circuitry can also lead to a protection).

no.
Remarks
12V missing or "low".

7202 When Trident IC is
defective, error 10 and
14 might also be
reported. Trident
communicates via
parallel bus, not via the
I2C bus. The I2C bus of
Trident is only used in
ComPair mode.
7315 The TV will not start-up
due to critical data not
available from the
NVM, but the LED will
blink the error code.
