Table 5-2 Error Code Table GDE
Error Error Name Description
A Vertical Output Failure This error indicates the Vertical Deflection pulse received at pin 9 on the TDA933x is not correct.
This can be caused by a failure in the HOP board or the Scan Board.
B Horizontal Flyback Failure This error indicates the Horizontal Flyback pulse received at pin 13 on the TDA933x is not correct.
This can be caused by a failure in the HOP board or the Scan Board.
C HOP Initialization Failure This error indicates the TDA933x was not initialized correctly during ACS board power up.
This can be caused by an error on the ACS board, the HOP board or the Small Signal Carrier
board.
D DAC Initialization Failure This error indicates the TDA8444 was not initialized correctly during ACS board power up.
This can be caused by an error on the ACS board, the HOP board or the Small Signal Carrier
board.
E Auto Convergence Failure This error indicates an error during the Auto Convergence process.
F Set References Failure This error indicates there was an error while setting the reference values.
G Sensor Pattern Failure This error indicates there is an error in a sensor or an error occurred while walking a pattern
across a sensor.
H General Initialization Failure This error indicates a general initialization software failure. This error is caused by the ACS board.
I HOP IIC Error This error indicates there was an IIC error while accessing the HOP.
This can be caused by an error on the ACS board, the HOP board or the Small Signal Carrier.
