4.2 Service mode
BUSINESS TO BUSINESS extra service menu
When a BtB module is detected, an extra field will appear in the first service menu:
BUSINESS TO BUSINESS.
If BtB ENABLED is set to YES and you press
GO
on Beo4, the TV will switch off
automatically, because it enters BtB (Hotel) mode, where the STBC controls the TV.
STBC POWER ON shows which power the STBC is running on: 5 Volt standby or
4V.
BtB IN FLASH shows whether or not the STBC module is in flash mode. This is for
future use.
Ignore Mode
In the case of a fatal component failure, the unit cannot be powered on. To service
a unit despite such a failure, the unit must be put into a state where the failure is
ignored. This state is called ignore mode, and is further described in “Adjustment
and Repair tips”.
Error Codes
The TV is able to detect certain types of error and display them on the screen.
The five latest TV errors are shown as error codes and displayed with the month/
date (four digits) as provided by the system clock. The most recent error is
displayed at the top. As the TV has no hardware clock the displayed month/date
will not be correct, but can be used to see if more errors have occurred at the
same date.
The following TV error types can be displayed:
. . . .
No error registered
DF
Data failure
POR
Power on reset failure
POR2
Power on reset failure 2
