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.

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.

It is a read only 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 RGB 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 keine/none 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 all 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. 33 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 aus /off 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 press to reset 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 ein/on 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. 60 sec The default is 60 sec. 15 Intensity of the backlight off sets with keyboard - on; sets without keyboard - off The above specified values are averages and can vary dependend on the LCD panel. A software which corresponds with the LCD panel must be programmed after changing the memory or the chassis.
Die angegebenen Werte sind Mittelwerte, die abhängig vom LCD-Panel abweichen können. Bei Austausch der Speicher oder der Chassisplatte muss die zum LCD-Panel passende Software eingespielt werden.
