As most signals are digital, it will be difficult to measure
waveforms with a standard oscilloscope.
Perform measurements under the following conditions:
• Service Default Mode.
• Video: Colour bar signal.
• Audio: 3 kHz left, 1 kHz right.
5.2 Service Modes
The Service Mode feature is split into one part:
• Factory Mode.
The Factory mode offer features, which can be used by the
Service engineer to repair/align a TV set. Some features are:
• Make alignments (e.g. White Tone), reset the error buffer
(Factory Mode).
Note: For the new model range, a new remote control (RC) is
used with some renamed buttons. This has an impact on the
activation of the Service modes. For instance the old “MENU”
button is now called “HOME” (or is indicated by a “house” icon).
