PF7001S, AO4286
All
power supplies are a black box for Service. When defective, a new board must be
ordered and the defective one must be returned, unless the main fuse of the
board is broken. Always replace a defective fuse with one with the correct specifications!
This part is available in the regular market.
Consult the Philips Service web portal for the order codes of the boards.
Important
delta’s with the 3010/4010/5010//5110 platform are:
• New power architecture for LED backlight
• “Boost”-signal is now a PWM-signal + continuous variable.
The control signals are:
• Lamp “on/off”
• DIM (PWM)
In this manual, no detailed information is available because of design
protection issues.
The output voltages to the chassis are:
• +12V for main board and audio amplifier (standby and on-mode) (for
715G6197,715G6297,715G6550)
• +12V(on-mode) ,+8.5V(Standby-mode)for main board and audio amplifier (for
715G6934 715G6677 715G6973)
• Output to the display; in case of
- IPB: High voltage to the LCD panel
- PSL and PSLS (LED-driver outputs)
- PSDL (high frequent) AC-current.
The
diversity in power supply units is mainly determined by the diversity in
displays.
The
following displays can be distinguished:
• CCFL/EEFL backlight: power board is conventional IPB
• LED backlight:
- side-view LED without scanning: PSL power board
- side-view LED with scanning: PSLS power board
- direct-view LED without 2D-dimming: PSL power board
- direct-view LED with 2D-dimming: PSDL power board.
PSL stands for Power Supply with integrated LED-drivers.
PSLS stands for a Power Supply with integrated LED-drivers with added Scanning
functionality (added microcontroller).
PSDL stands for a Power Supply for Direct-view LED backlight with 2D-dimming
