Vor dem Öffnen des Gehäuses den Netzstecker ziehen!
Achtung: ESD-Vorschriften beachten
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.
Durchführen von Messungen
Bei Messungen mit dem Oszilloskop an Halbleitern sollten Sie nur
Tastköpfe mit 10:1 - Teiler verwenden. Außerdem ist zu beachten,
dass nach vorheriger Messung mit AC-Kopplung der Koppelkondensator des Oszilloskops aufgeladen sein kann. Durch die Entladung
über das Messobjekt können Bauteile beschädigt werden.
Messwerte und Oszillogramme
Bei den in den Schaltplänen und Oszillogrammen angegebenen
Messwerten handelt es sich um Näherungswerte!

General Section
General Notes
Before opening the cabinet disconnect the mains plug!
Attention: Observe the ESD safety regulations
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.
Carrying out Measurements
When making measurements on semi-conductors with an oscilloscope, ensure that the test probe is set to 10:1 dividing factor. If the
previous measurement was made on AC input, please note that the
coupling capacitor in the oscilloscope will be charged. Discharge via
the item being checked can damage the components.
Measured Values and Oscillograms
The measured values given in the circuit diagrams and oscillograms
are approximates!

Gives information about the last update time of the SW running. It is a read only option and can
not be set.
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.
This option will enable or disable the Initial setup for the TV. Setting this option to On, the TV will
open from the Quick setup menu. Setting this option to Off will disable this option.
Factory reset option executes a reset operation for the NVRAM. Pressing OK when this option is
selected will erase the NVRAM and load default values to NVRAM.
This option selects the Power option for the TV. Setting this option to On the TV will switch to the
last state for power on transition. Setting this to Off will disable this option and the TV will always
switch to Stand-by state while power on transition.
This option sets the OSD timeout for the main menu structure. Selections are 5, 15 and 60 secs.
The default is 60 sec.
