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!

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!

Geräte- und Display-Varianten

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 des Service
Manuals Ihr „Product Code“ oder Ihre
Display-Variante nicht aufgeführt sein,
können Sie eine aktualisierte Version
auf dem GRUNDIG Service-Portal
„http://service.grundig.de“ finden.
Überprüfen Sie vor Austausch der
Hauptplatte, ob die Aufkleber der Plati­nen identisch sind.

Austausch der Speicher oder Chassisplatte

Bei Austausch der Speicher oder der Chassisplatte muss die zum
LCD-Panel passende Software eingespielt werden. Anschließend
müssen alle gerätespezifischen Parameter überprüft und gegebe­nenfalls eingestellt werden (siehe "Service- und Sonderfunktio­nen").

Product and 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 your „Product Code“ or display variant
is not mentioned in the spare parts list
of the service manual, please have a
look for a current version at the

GRUNDIG service portal „http://
service.grundig.de“.

Before changing the main board please
check whether the labels on the boards
are identical.

Exchange of Software or Chassis

A software which corresponds with the LCD panel must be pro­grammed after changing the memory or the chassis. Afterwards all
device-specific parameters must be checked and if necessary setu­ped (see part "Service and Special Functions").

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.

- Perform a factory reset:

- 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.

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

- Scart 2 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.

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

Attention:
The selection of other commands than "appstest 157" and
