Einführung

Die 2. Ergänzung zum Service Manual Chassis LE≥37" wurde bereits
im März 2007 unter der Materialnummer 720100505200 veröffentlicht.

Dies ist die korrigierte Version, die unter der Materialnummer
720100505201 veröffentlicht wurde.

Grund: Die Geräte Lenaro 40 LXW 102-8720 Dolby und Lenaro 37
LXW 94-8720 Dolby mit den Product Codes BBZ und BBY wurden nie
produziert. Die Geräte wurden nur mit den Product Codes EMQ und
EMN produziert, die in dieser korrigierten Version dokumentiert sind.
Bitte ersetzen Sie die 2. Ergänzung zum Service Manual Chassis
LE≥37" vom März 2007 (Materialnummer 720100505200) durch diese
Version.

In dieser Service-Manual-Ergänzung ist die Chassisplattenvariante
GW2.190R-2 (2 HDMI-Eingänge / kein DVI-Eingang / Power Supply
LW6.194 auf Chassis integriert / geändertes DDRAM) sowie Geräte­varianten, die mit diesem Chassis ausgestattet sind, dokumentiert.

Hinweis:

Grundlage für den Service sind folgende Service Manuals:
– Service Manual Sicherheit, Materialnummer 720108000001
– Service Manual Chassis LE ≥ 37", Materialnummer 720100505000

never produced. Only sets with product codes EMQ and EMN are
produced, which are published in this corrected version. Please
replace supplement 2 of Service Manual Chassis LE≥37" from March
2007 (part number 720100505200) by this version.

This Supplement of Service Manual describes chassis variant
GW2.190R-2 (2 HDMI inputs / no DVI input / Power Supply LW6.194

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 Ihr "Pro­duct Code" oder Ihre Displayvarian­te 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.

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 your "Product Code" or
display variant is not mentioned in
the spare parts list please have
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.

Austausch von 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).
