7.2.1 Power Supply Unit
All power supplies are a black box for Service. When defective,
a new panel must be ordered and the defective one must be
returned, unless the main fuse of the panel 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
panels.
Important delta’s with the TPM14.2E LA classis platform are:
• New power architecture for LED backlight
• “Boost”-signal is now a PWM-signal + continuous variable.
The control signals are:
• Stand-by
• Lamp “on/off”
• DIM (PWM) (not for PSDL)
In this manual, no detailed information is available because of
design protection issues.
The output voltages to the chassis are:
• +4V7-STANDBY (Stand-by mode only)
• +12V (on-mode)
• +Vsnd (+24V) (audio power) (on-mode)
• +12V (bolt-on power) (on-mode)
• +12V (stanby:8.5V Output;on-mode:12V Output)
• +12_audio(+12V) (audio power) (on-mode)
• 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.
7.2.2 Diversity
The diversity in power supply units is mainly determined by the
diversity in displays.
The following displays can be distinguished:
• CCFL/EEFL backlight: power panel is conventional IPB
• LED backlight:
- side-view LED without scanning: PSL power panel
- side-view LED with scanning: PSLS power panel
- direct-view LED without 2D-dimming: PSL power panel
- direct-view LED with 2D-dimming: PSDL power panel.
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.

7.3 DC/DC Converters
The on-board DC/DC converters deliver the following voltages
(depending on set execution):
• +5V-STANDBY, permanent voltage for the Stand-by
controller, LED/IR receiver and controls
• +12V, input from the power supply for the panel common
(active mode)
• +12V, input from the power supply for audio amplifier
• +1V2, core voltage supply for MT5591
• +1V5, supply voltage for DDR2 (diagram B03B)
• +3V3, general supply voltage
• +5V, supply voltage for USB and CAM
• +3V3-TUN, supply voltage for tuner
• +5V-USB, input intermediate supply voltage for USB
• +3V3 from the power supply for the scaler IC MT5591
• +12V input from the Power supply for the Ambilight
common.
• +3V3-DVBS, clean voltage for DVB-S2 channel decoder.
• +1V2-DVBS, core voltage for DVB-S2 channel decoder.

converters with its current consumptions:
