After repair of an error that has triggered the display of an error code, the error code
has to be deleted. This is done by pressing GO in the MONITOR INFORMATION menu.
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:
IC Function
Colour decoder & IF (HIP)
TV tuner
M2 Processor
Modulator
Power Link
IOP Main processor
Digital Sound AC3
Sound processor
Video processor (HOP)
CTI
Real-time clock
S - Standby mode
A - Audio mode
V - Video mode
If an error occurs in the EEPROM (6IC6) that prevents output of geometry data to
the TV set, the microcomputer will replace the missing data with default data
stored in the EPROM (6IC3) module 999.
