• Press & Hold the {P +} button on the TV set, and switch the TV On, by its Mains Power Switch.
• The 'L+' button on the TV set allows to discover other potentially defective interfaces.  If there is no other defective interfaces, the software tries to start the TV set.
• The error messages for the DSP, SAT & PIP modules are only indicated if these modules are actually fitted and the least one IIC bus address on the defective module has been identified.  These error messages refer only interference only in the IIC bus, that is, to those moldules or integrated circuits which do not return an Acknowledge bit via IIC bus, for example, to indicate that there is no operating voltage present on the module, that there is a break in the circuit path, or that the IIC interface is defective.

SAT Module Programming 

• Press and Hold the "i" button on the remote control and switch the TV On, with the Main Switch.  Consequently, on replacement of the EEPROM on the SAT module for example, the stored station table is read out from EPROM IC87030.

CANCELLING THE PARENTAL LOCK

• To cancel personal code number, press the buttons { < > Dn Up} in sequence.

EPROM Version Number

• Press button "i" to call up the "DIALOGCENTER" menu.  The version number is shown by pressing "AUX" button.  The index '07' of the part number (19798-311-07) indicates the EPROM version.

SWITCHING ON WITH TEST PATTERN OR TV MODE

• Call up the Menu "Switch On with test pattern or TV" with "i" button via"DIALOGCENTER" => 'SERVICE'.  On selection of 'Test Pattern' an integrated test pattern will appear on the screen when switching the TV on again.  The 'TXT' button is used to switch the TV back to Program Mode (if no other button is pressed during a period of ca.20s the test pattern reappears).
