IIC bus error
An IIC bus error means that the communication on the bus fails when the
microcomputer tries to communicate with the address in question.
In most cases this means that the addressed IC is defective but the defect could
also be in one of the components surrounding the IC or in other components on
the bus. Adresses in connection with IIC bus errors:
On modes:
S - Standby mode
A - Audio mode
V - Video mode
DF Data failure
If an error occurs in the EEPROM (IC) that prevents output of geometry data to
the TV set, the microcomputer will replace the missing data with default data
stored in the EPROM (IC3) module .
POR Power on reset failure
Reset or update failure of IC30 (TDA3H module ) during start up.
POR Power on reset failure
Reset or update failure of IC700 (TDA330H module ) during start up.
