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!

Displayvarianten

Je nach Verfügbarkeit werden Displays ver­schiedener Hersteller eingebaut. Dies führt zu
unterschiedlichen Chassis-Bestückungen, so­wie zu Änderungen in der Software. Bei Er­satzteilbestellungen und Software-Updates
achten Sie bitte auf das eingebaute Display,
sowie auf den "Product Code". Angaben dazu
finden Sie auf der Geräterückseite. Sollte in
der Ersatzteilliste eine Displayvariante nicht
aufgeführt sein, wenden Sie sich bitte an die
technische Hotline.
Überprüfen Sie vor Austausch einer Chassis­platte, ob die Aufkleber der Chassisplatte iden­tisch sind.

Spare Parts Lists .................................. 3-1…3-5

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!

Display Variants

Depending on availability displays of different
manufacturer are built in. This results in diffe­rent chassis mountings as well as a different
software. On spare parts orders as well as
software updates take care of the fitted display
as well as of the "Product Code". Therefore
you can find information on the labels on the
rear side. If a display variant is not mentioned
in the spare parts list please contact the
technical hotline.
Before changing the chassis board please
check whether the labels on the boards are
identical.

Automatischer Abgleich

Der automatische Abgleich muss immer nach Austausch der Chas­sisplatte, des Displays sowie nach einem Software-Update oder ei­nem "Factory Reset" durchgeführt werden.

Alle gerätespezifischen Parameter müssen vor dem automatischen
Abgleich überprüft und gegebenenfalls eingestellt werden.

- Service Mode aktivieren.

- Im Service-Menü "Selections" Menüpunkt "Factory Reset" an­wählen und mit Taste "OK" bestätigen. Wenn die Menüpunktfarbe
von rot nach schwarz wechselt, Gerät ausschalten (Händlermenü
nicht beenden!).

- PC mit "Gprobe 5"-Programm an die AV1 Buchse anschließen
und PC und Gerät einschalten.

- Service Mode nochmals aktivieren.

- Im Service-Menü "Adjustment" Menüpunkt "Factory Mode" auf
"On" stellen und Service Mode verlassen.

- "Gprobe 5"-Programm starten.

- In das Eingabefeld klicken, mit den Cursor-Tasten (up und down)
den Befehl "appstest 157" auswählen und mit Taste "Execute"
starten (Fig.1).

-Gerät aus- und wieder einschalten.

- PC-Eingang:

- 100%-Farbbalkentestbild über den PC-Eingang einspeisen, PC­Eingang auswählen.

- Mit dem "Mauszeiger" in das Eingabefeld klicken (Fig.1), mit den
Cursor-Tasten (up und down) den Befehl "appstest 34" auswäh­len und mit Taste "Execute" starten. Während des Abgleichs wer­den die Einstellungen am PC angezeigt.

- Wird "Calibration x ends" angezeigt, ist der Vorgang beendet.

- S-Video-Eingang:

- 100%-Farbbalkentestbild über den S-Video-Eingang einspeisen,
S-Video-Eingang auswählen.

- Mit dem "Mauszeiger" in das Eingabefeld klicken, mit den Cursor­Tasten (up und down) den Befehl "appstest 34" auswählen und
mit Taste "Execute" starten (Fig.2). Während des Abgleichs wer­den die Einstellungen am PC angezeigt.

- Wird "Calibration x ends" angezeigt, ist der Vorgang beendet.

- Scart 2-Eingang:

- 100%-Farbbalkentestbild über den Scart 2-Video-Eingang ein­speisen, Scart 2-Video-Eingang auswählen.

- Mit dem "Mauszeiger" in das Eingabefeld klicken, mit den Cursor­Tasten (up und down) den Befehl "appstest 34" auswählen und
mit Taste "Execute" starten (Fig.2). Während des Abgleichs wer­den die Einstellungen am PC angezeigt.

- Wird "Calibration x ends" angezeigt, ist der Vorgang beendet.

Achtung:
Die Auswahl anderer Befehle als "appstest 157" und "appstest
34" kann zu Gerätefehlfunktionen führen!
Wählen Sie beide Befehle sehr sorgfältig aus!

Autocalibration

Autocalibration must be done after changing the chassis or the pa­nel as well a after software update or factory reset.

All device-specific parameters must be checked and if necessary
setuped before starting autocalibration.

- Activate service mode.

- Select menu item "Factory Reset" in the service menu "Selecti­ons" and confirm with button "OK". Switch off the set when the
colour of the menu item switches from red to black.

- Connect a PC with "Gprobe 5" software to AV1 socket and switch
on the PC and the set.

- Activate service mode again.

- Set menu item "Factory Mode" in the service menu "Adjustment"
to "On" and leave the service mode.

- Start "Gprobe 5" Software.

- Click to the input field and select via the cursor buttons (up and
down) the "appstest 157" command. Start the command with
button "Execute" (Fig.1).

- Switch the set off and on.

- PC Input:

- Feed in a 100% colour bar test pattern via the PC input and se­lect the PC input.

- Click to the input field and select via the cursor buttons (up and
down) the "appstest 34" command. Start the command with but­ton "Execute" (Fig.2). During adjustment the settings will be dis­played on the PC.

- "Calibration x ends" will appear on the Gprobe screen when the
process is finished.

- S-Video Input:

- Feed in a 100% colour bar test pattern via the S-video input and
select the S-video input.

- Click to the input field and select via the cursor buttons (up and
down) the "appstest 34" command. Start the command with but­ton "Execute" (Fig.2). During adjustment the settings will be dis­played on the PC.
