Protections - Philips 7629 Service Manual

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).
