5.2 Error Code
5.2.1 Introduction
Error codes are required to indicate failures in the TV set. In principle a unique error code is available for every:
• Activated (SW) protection.
• Failing I2C device.
• General I2C error.
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 never leads to a deadlock situation. It must always be diagnosable (e.g. error buffer via OSD or blinking LED).
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.
