Exit “Factory Mode”; Sanken Display Supply; Ssb Service Supply Connector; Tuner - Philips 32PFL9432/98 Service Manual

5.8.5 Exit "Factory Mode"
When an "F" is displayed in the screen's right corner, this
means that the set is in "Factory" mode, and it normally
happens after a new SSB has been mounted.
To exit this mode, push the "VOLUME minus" button on the
TV's keyboard control for 5 seconds and restart the set.
5.8.6

Sanken display supply

The 47" sets in this chassis come with a Sanken buy-in supply.
The result of a failing Sanken display supply, e.g. one of the
following voltages is missing: +400V, +12V or +24V, will lead to
protection (blinking error 63). The set is switched off.
When the primary circuit of the on-board platform supply fails,
there is a high possibility that the main fuse of the Sanken
display supply will break. In this case the Sanken display
supply must not be replaced completely, just replace the
Sanken main value fuse and repair the on-board platform
supply. For safety reasons, make sure to use the correct fuse
type.
5.8.7

SSB service supply connector

Connector 1B40 can be used to apply external supply (+12V
and +5V). In this way you do not need mains supply for
troubleshooting on the SSB. e.g. component level repair.
5.8.8

Tuner

For access to the components located under the tuner itself,
you need to desolder the ground connections and bend the
tuner up. To maintain a good performing tuner you must make
a new ground connection to the SSB, for instance by use of a
wire.
Caution: In case you replace the tuner, always check the tuner
option!
5.8.9 UI over PCI bus
The UI is not integrated in the RGB signal but is sent from
PNX85xx to PNX5050 via the PCI bus. TXT and MHEG are
integrated in the RGB signal. So if you have TXT signal but no
UI, check the PCI bus.
