Allgemeiner Teil
Allgemeine Hinweise
Achtung: ESD-Vorschriften beachten
Vor dem Öffnen des Gehäuses zuerst den Netzstecker ziehen!
Leitungsverlegung
Bevor Sie die Leitungen und insbesondere die Masseleitungen lösen,
muss die Leitungsverlegung zu den einzelnen Baugruppen beachtet
werden. Nach erfolgter Reparatur ist es notwendig, die Leitungsführung wieder in den werkseitigen Zustand zu versetzen um evtl.
spätere Ausfälle oder Störungen zu vermeiden.
Messwerte und Oszillogramme
Bei den in den Schaltplänen und Oszillogrammen angegebenen
Messwerten handelt es sich um Näherungswerte!
Achtung: Chassisvarianten
Einige Gerätetypen wurden sowohl mit Chassis P6 als auch mit Chassis P7 produziert. Für
Chassis P6 ist das Service Manual
720100493000 maßgebend. Auf dem Typenschild (Geräterückseite) ist die Chassisbezeichnung aufgedruckt. Beachten Sie hierbei
auch den Produktcode der links neben der
Seriennummer zu finden ist.

General Section
General Notes
Attention: Observe the ESD safety regulations
Before opening the cabinet disconnect the mains plug!
Wiring
Before disconnecting any leads and especially the earth connecting
leads observe the way they are routed to the individual assemblies. On
completion of the repairs the leads must be laid out as originally fitted
at the factory to avoid later failures or disturbances.
Measured Values and Oscillograms
The measured values given in the circuit diagrams and oscillograms
are approximates!
Attention: Chassis variants
Some types of sets are produced with chassis
P6 as well as with Chassis P7. For chassis P6
Service Manual 720100493000 is standard.
Type of chassis is printed on the type label (rear
side). Please also pay attention of the product
code which you can find left from the serial
number.

option and can not be set.
LCD TVs only: Backlight on time option reserved.
Sets the prescale values for the input sounds entering the scart input of the MSP (Micronas Sound Processor). Changing this value you can adjust the level of the output sound going to
loudspeakers for all the sources except the Tuners. The range is between 0 and 100.
Sets the prescale values for the Nicam standard sounds for tuner inputs. Changing this value you
can adjust the level of the output sound going to loudspeakers for Nicam sounds entering the analog sound input of MSP. The range is between 0 and 100.
Sets the prescale values for the FM/AM standard sounds for tuner inputs. Changing this value you
can adjust the level of the output sound going to loudspeakers for FM/AM sounds entering the
analog sound input of MSP. The range is between 0 and 100.
Sets the input voltage going to IF decoder AGC pin. Changing this value you can adjust this voltage for optimum Tuner performance. The range is between 0 and 31.
These are used for color bias adjustment. The range is between 0 and 255
Forces the video format to the desired format. Selectable formats are Auto, PAL, NTSC and SECAM.
Gives information about the video colorspace input to PW181 IC. Do not change this value unless
an error occurred in the colors displayed.
Activates the internal pattern of PW181 IC. There are 3 choices: none, vert bars, solid color. None
will deactivate the internal pattern. Vert bars choice activates the bar pattern for the selected color
component. Solid color activates the solid pattern with one color selected in color component and
also you can change the level of the color by solid field level.
Selects the color for the internal pattern of PW181 IC. There are 4 choices: all, red, green and
blue. If you choose all, you can see the white pattern and if you choose one of the other choices
you can see the test pattern with the selected color.
This option will adjust the level of the colors for the test pattern. The range is between 1 and 64.
