Introduction
Options are used to control the presence/absence of certain
features and hardware.
How to Change an Option
Different from other Philips TV sets, the options are not
represented as bits and bytes, but with clear text.
The option settings are a part of the Service Menu. The method
of entering the Service Menu and the structure of the Service
Menu are described in “Software Alignments” below.
8.2
General Alignment Conditions
Perform all electrical adjustments under the following
conditions:
•
AC voltage and frequency: 230 V / 50 Hz.
•
Connect the set to the mains voltage via an isolation
transformer with a low internal resistance.
•
Allow the set to warm up for approximately 20 minutes.
•
Measure the voltages and waveforms in relation to chassis
ground (with the exception of the voltages on the primary
side of the power supply). Never use the cooling fins /
plates as ground.
•
Test probe: Ri > 10 Mohm; Ci < 2.5 pF.
•
Use an isolated trimmer / screwdriver to perform the
alignments.
