Hinweise

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 wie z.B. Chassis, Bildrohrplatte, Ablenkeinheit, Lautsprecher usw. 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.

Netzkabel

Diese Geräte dürfen nur mit dem Original-Netzanschlusskabel mit integrierter Entstördrossel betrieben werden. Dieses Netzkabel verhindert Störungen aus dem Netz und ist Bestandteil der Gerätezulassung. Im Ersatzfall bestellen Sie bitte ausschließlich das Netzkabel laut Ersatzteilliste.

Notes

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 like the chassis, picture tube panel, deflection unit, loudspeaker and so on. On completion of the repairs the leads must be laid out as originally fitted at the factory to avoid later failures or disturbances.

Mains cable

The TV receiver must only be operated with an original mains connecting cable with an interference suppressor choke integrated in the mains plug. This mains cable prevents interference from the mains supply and is part of the product approval. For replacement please order exclusively the mains connecting cable specified in the spare parts list.

Correction

The following adjustment No. 2 for the Screen grid voltage substitutes the adequate adjustment in the Service Manual 720100261000, page 3-2.

Adjustment Preparation Adjustment Procedure

2. Screen grid voltage U

Feed in a grey scale test pattern.

Adjust the screen brightness so that the gradation from the darkest grey scale value to black is just still visible (2.7V to IC150-(17)). Contrast: Minimum Measure test points R, G, B (on the CRT panel) to determine the test point with the highest black level and connect this point to the oscilloscope.

With the control UG2 (Splitt Transformer) adjust the black level at the test point with the highest black level to 110V…115V for14" picture tubes and 145V…155V for 15"…21" picture tubes.
